HTML tags: what they are, what they are for, which ones are the most useful
If every website were a building, HTML tags would be the bricks with which it is constructed. They are in fact the framework that supports the body of content, images, and functionality that make up the online experience, an invisible language that shapes the Web and helps shape our pages. These small commands tell the browser how to interpret and display the content of a page, allowing it to interpret the content correctly and display it to users in a consistent and functional manner. There are a hundred different HTML tags that we can use, and each of them has a specific function, to be exploited in the appropriate way to create a visually appealing and search-engine optimized web page. So with this guide we try to find out what exactly these HTML tags are, what are the main types to master, and how they can affect the SEO of our site .
What are HTML tags
HTML tags are the basic language used to create Web pages, and essentially they are small commands that guide the browser by instructing it how to interpret and display the content of a page. These tags reside in the cornerstone element of any web page, namely its HTML code, which stands for HyperText Markup Language, which we can imagine as what brings web pages to life.
More precisely, HyperText Markup Language is the programming language used to describe structured documents and to create web pages and applications on the Internet, and which we view every moment as users from our browsers, such as Chrome, Firefox, and Edge. From the perspective of HTML source code, a page is a collection of elements, each of which has a specific role, such as “article title,” “text,” “subtitle,” and so on, and these elements are defined by tags, marked by the special characters “<”, “>” and “/”.
In fact, each HTML tag is enclosed in angle brackets (< >), and most of them work in pairs, that is, providing an opening tag (<tag>) and a closing tag (</tag>) in which to insert and enclose a specific portion of code, i.e., the content we wish to format. Between the opening and closing tags is in fact inserted what we wish to display on the page, such as some text, an image, or a hyperlink.
The definition of HTML tags
HTML tags are the actual building blocks with which we construct web pages. Defining an HTML tag is quite simple: it is a command that tells the browser how it should interpret and display the content enclosed between its ends.
But what do the tags really mean?
Each has a specific function and communicates something to the browser, from text formatting (e.g., <b> for bold, <i> for italics) to the basic structure of the page (e.g., <div>, <header>, <footer>). So the role of tags is twofold: on the one hand, they organize the structure of the content for the browser; on the other hand, they make the code consistent and clear for other developers who might work on the project in the future.
If we think about it, when we talk about tags we are referring to a kind of common language between us and the browser. It is through these “placeholders” that we communicate to the browser where, how, and what to show. For example, the <a> tag is used to create a hyperlink, a link that may take the user to another section of the site, to an external page, or to download a file. Each tag has a precise “meaning” dictated by the HyperText Markup Language ( HTML ) standards, which is constantly updated by international consortia such as the W3C to adapt to new technologies and needs of the modern web.
Therefore, these labels (literal translation of tags) serve to specify and define how the browser should format and display content. Thus, they are the ones that determine whether a text should be italicized or bold, whether a line break should be inserted, a bulleted list, and much more.
But HTML tags are not just formatting tools, for they can also be powerful allies for SEO, because search engines such as Google use HTML tags to understand the structure and content of a web page and then index it correctly in search results.
The evolution of HTML tags: from their origins to HTML5
Despite their simplicity, HTML tags have come a long way, marking the history of digital communication: their evolution has not occurred in a linear fashion, but rather through increasing depth and complexity, parallel to the expansion of the uses and functionalities offered by web technology. And in that time they have transformed from simple text markup to critical elements in the construction of dynamic and accessible Web experiences.
HTML was developed in the early 1990s by Tim Berners-Lee, one of the pioneers of the Internet. The idea was simple, but revolutionary: to create a language that would allow text to be “marked up” or “tagged” (hence the term tags) with useful formatting and structure cues so that it could be viewed by a Web browser. The result? A standardized way of formatting information to make it accessible in a hypertext environment, i.e., the Web.
Early HTML tags were extremely basic, intended primarily to organize text within a page. For example, elements such as <p> (paragraph), <b> (bold) and <a> (anchor, for hyperlinks) provided essential functionality for the structure and navigability of Web pages. However, as the Internet gained centrality, so did HTML. New requirements for design, interactivity, and compatibility between different browsers led the W3C (World Wide Web Consortium) to develop increasingly advanced versions of HTML.
With the introduction of HTML4 in the 1990s, greater complexity began to emerge, supporting the creation of more complex Web sites with a richer user interface. Meta tags were introduced in HTML4, which were critical for SEO and meta-descriptive data management. However, with the growing importance of connectivity and usability on various devices, it became clear that HTML needed to evolve further.
The advent of HTML5 represented a crucial turning point. Officially released in 2014 after years of development, HTML5 not only simplified some of the complexities introduced with HTML4, but also brought major innovations. These include new semantic tags such as <header>, <footer>, <article>, and <section>, which help to better structure content and improve search engines’ understanding of context. In addition, HTML5 has increased native multimedia support (for video, audio, and graphical canvas), eliminating the need for external plug-ins such as Flash.
HTML tags, HTML meta tags and attributes: differences between these elements
It is appropriate at this point to open a small parenthesis to clarify what are the differences between “HTML tags,” “HTML meta tags,” and “tag attributes,” terms that refer to distinct concepts and different tasks in the creation of a web page and in the definition of HTML elements, i.e., each element of the page that is part of the content. Especially when we are first starting out withHTML or are SEO beginners, it is indeed easy to confuse the meaning of these elements, which although they are similar in some ways, yet have quite distinct functions within the syntax of an HTML document.
Understanding their differences is crucial to being able to develop code that is robust and capable of responding correctly to the needs of the modern Web.
In summary:
- HTML tags create the structure and main visible content of the page.
- Meta tags provide non-visible information (meta-information) about how the page is to be interpreted by search engines and browsers.
- Attributes specify additional details about how HTML tags should behave, modifying how they function.
More specifically, HTML tags form the skeletal structure of a web page and are used to define the elements that make up the content. Each tag encapsulates specific parts of the content and tells the browser how that content is to be displayed.
Meta tags differ substantially from HTML tags in their function. While HTML tags direct the display of content, meta tags provide data about the data itself, or “metadata.” These tags are located within the <head> section of the HTML document and are not viewed by the end user, but they have a huge impact on how search engines understand and index the page, as well as handling various technical aspects such as display device and text encoding. Meta tags do not require to be closed and in many cases are self-contained. Meta tags are used to communicate with browsers and search engines, offering information that is not displayed directly on the page but is crucial for elements such as SEO, usability, and cross-browser compatibility.
Attributes, unlike both HTML tags and meta tags, do not represent new elements inserted into the web page. Rather, they are textual identifiers added inside HTML tags to define additional properties or to specify additional information about an HTML element. Attributes are composed of a “name-value” pair, formatted as attribute_name=“value,” and are placed within the opening tag. For example, the src attribute indicates the source of an image within the <img> tag, as in <img src=“image.jpg” alt=“Photo description”>. The value assigned to each attribute significantly changes the behavior of the HTML tag to which it belongs. For example, attributes are critical in controlling the layout of a page, interactivity with the user, and other relevant functions such as readability and accessibility of content. Understanding these differences not only helps prevent common mistakes, but also allows you to better master thearchitecture of a web page and optimize the site for certain goals, including SEO.
In any case, all three represent essential components that work together to create a functional, accessible, and search-engine-optimized web page, and that is precisely why we cannot go wrong either in theory or especially in practical applications.
HTML tags are the fundamental building blocks of any web page and are used to define and structure the content of a web page; each HTML tag has a specific meaning and tells the browser how to interpret the content within the tag, affecting how an HTML element is displayed .
HTML meta tags, on the other hand, are a specific type of HTML tag that provide information about the web page itself, rather than structuring its content. These tags should be placed within the <head> element of an HTML page. HTML meta tags are invisible to the user, but they play a crucial role in search engine optimization and ensuring that the web page functions properly.
Finally, tag attributes are additional information that can be added to an HTML tag to change its behavior or appearance and to describe the characteristics of an HTML element. For example, in the image tag <img src=“image.jpg” alt=“Image description”>, src and alt are attributes that, respectively, tell the browser where to find the image to display and provide a textual description of the image, which can be displayed if the image cannot be loaded and which can be used by screen readers for people with visual impairments.
To summarize, then:
- HTML tags contain instructions on how to display an element on the page.
- HTML elements are the contents of the page enclosed within the tags.
- HTML attributes provide additional information about HTML elements and are displayed within the HTML tag.
- HTML meta tags are a subcategory of HTML tags, which provide information about the web page that is not directly displayed to users.
The grammar of HTML tags: a universal language
The grammar of HTML tags is simple and universal, which allows anyone to learn how to use them simply with a little practice and attention.
Each HTML tag has a specific function and must be placed in the right place within the page code, while also respecting the syntax in order to actually communicate sensible instructions to the browser and avoid errors.
As mentioned, an HTML tag consists of a tag name enclosed in angle brackets < >, and most HTML tags have an opening and a closing command, with the content placed in between. For example, <p> is an opening tag for a paragraph, and </p> is the corresponding closing tag; thus, a paragraph of text would be written as <p>Thisis a paragraph.</p>.
Servers read HTML code to understand and display the content of a page, and reading is done from top to bottom, just as it is done at normal human reading.
The grammar of tags is not too complex, and there are just a few rules to know and follow, starting with the structure of this element, which generally consists of three elements:
- An opening tag, which begins with a < > symbol.
- The content, which is the brief instructions on how to display the element on the page.
- A closing tag, which ends with a </ > symbol. It is important to note that the closing tag has the same text as the opening tag, from which it differs only by the addition of the slash character (/) that clarifies the command.
However, some HTML tags can remain open, that is, they do not require a closing tag, and are typically used for metadata or line breaks. These HTML tags are known as “empty” or “self-closing” tags precisely because they do not need a closing tag: they are designed to hold information that does not need textual content or other HTML elements inside, and some common examples of empty tags include <img> for images, <br> for a line break, and <input> for input fields in forms.
For example, an image tag can appear as <img src=“image.jpg” alt=“Image description”>, without the need to specify a closing </img> command. Instead, the src attribute specifies the path to the image, and the alt attribute provides a textual description of the image, which can be used by search engines and screen readers.
However, it is good practice to include a space and a slash at the end of the tag (e.g., <br /> or <img src=“image.jpg” alt=“Image description” />) in XHTML and some versions of HTML: this helps maintain compatibility between different versions of HTML and ensures that the code is interpreted correctly by all browsers.
HTML tag rules: how tags are written and where they should be placed in HTML text
There are also few formal rules for writing these elements correctly: essentially, HTML tags should be placed strategically and consciously within the code to define the structure and layout of the site or page, because each has its own function and is only “activated” in the area where the command is open.
To put it more simply, the <head> tag, for example, serves to contain metadata about the web page and links to CSS style sheets: and it is located at the beginning of the document, just after the opening <html> tag, and does not contain any user-visible content, because it communicates its crucial information “only” to the browser and search engines. The <body> tag, on the other hand, encloses all the visible content of the web page, such as text, images, links, tables, lists, and so on: it should be inserted immediately after the closing </head> tag and extends to the end of the HTML document, just before the closing </html> tag.
Basically, then, the other HTML tags should be placed within the <body> tag to structure and format the visible content of the web page; the exact location of these elements depends on the type of content we are creating and the visual effect we want it to present to users.
In fact, proper organization of HTML tags within the code serves to provide reading support for people browsing the site, and at the same time they help browsers interpret and display the content correctly and, not least, they can also help improve SEO, as we shall see.
Correct syntax of HTML tags: how to avoid common mistakes
Learning how to correctly write an HTML tag is the first step in building robust and error-free web pages. Although it may sound simple, there are some basic rules that it is crucial to follow to ensure that the code is interpreted correctly by browsers and is easily readable by other developers.
First of all, it is essential to understand the basic syntax of an HTML tag. An HTML tag consists of three main parts: the opening tag, the content tag, and the closing tag. A classic example is the <p> tag used for paragraphs – example <p>This is a paragraph of text.</p>.
In the opening tag <p>, the < symbol indicates the beginning of the tag, followed by the name of the tag itself (p in this case) and closed by the > symbol. The content tag is the text that will appear on the page, and the closing tag </p> follows the same syntax as the opening tag, but with the addition of the slash / to indicate closure.
But there are some nuances to pay attention to:
- Self-closing tags: Some tags such as <img>, <br>, and <hr> do not require a closing tag. These tags are known as self-closing tags. The correct syntax, especially in HTML5, requires immediate closing of the tag with a slash / before the > symbol, e.g. <img src=“image.jpg” /> />. This ensures that the code is compatible even with stricter standards such as XHTML.
- Proper nesting: Some HTML tags can be “nested,” that is, inserted one inside the other. When nesting tags, it is critical to close them in the reverse order of how they were opened. For example,
<div>
<p><strong>Important Text</strong></p>
</div>
In this case, we open the tags in the following order: <div>, <p>, <strong>. Therefore, the <strong> should be closed first, followed by the <p> and finally the <div>.
- Case sensitivity: In general, HTML is not case sensitive, which means that <P> and <p> are treated the same way by browsers. However, to maintain readability and code cleanliness, it is a good practice to use lowercase tags as preferred by HTML5.
- Proper attribution of attributes: When writing attributes within tags, you must enter them in the correct format: attribute name = “value.” For example, when we add a source to an <img> tag, we would write it as <img src=“image.jpg”>. Don’t forget to always enclose attribute values in quotation marks to avoid ambiguity.
Following these syntax rules not only reduces the likelihood of errors in the code, but also makes our work more professional and easier to maintain. Any error in writing an HTML tag can lead to page display problems or negatively affect the site’s indexing in search engines. Refining the technique of writing HTML tags is therefore an investment in the future of our site and its overall performance.
The main errors in writing HTML tags and their consequences
Having clarified the theoretical issues, let’s turn to some rather practical aspects involved in managing and writing HTML tags. As mentioned, we are not talking about rather complicated aspects or requiring specific skills, but still there are many mistakes that can be made, which cause potential consequences for the web page that it is good to be aware of, so as to take appropriate action. When working withHTML, in fact, it is easy to make mistakes that, while sometimes subtle, can have significant consequences for the functioning of the site or its ability to be properly indexed by search engines. Recognizing and correcting these errors is essential to ensure that our HTML code is consistent, readable and functional.
- Failure to close tags
One of the most common errors is the omission of closing tags: as mentioned, many HTML tags work in pairs, requiring an opening tag and a closing tag. If we forget to close a tag, the browser may not be able to interpret the code correctly, causing display problems on the page-most often, extending the command to the next closing tag. An unclosed tag can compromise the page display, breaking the layout and causing rendering problems. Alternatively, search engines may have difficulty understanding the page structure, negatively affecting SEO.
- Misuse of self-closing tags
Some HTML tags, such as <img>, <br>, and <hr>, are self-closing, which means they do not require a specific closing tag such as </img>, </br>, </hr>. However, it is common to forget to add the slash (/) that closes these tags, which is practical especially in older versions of HTML that are not compatible with XHTML or HTML5. Formatting the code correctly helps avoid compatibility problems. Avoiding nonstandard use of self-closing tags not only improves code readability, but also prevents any rendering problems that may arise on some browsers.
- Misuse of header tags
Header tags(<h1>, <h2>, <h3> and so on) should be used to structure the content, not to format the text: using these tags improperly could confuse search engines and compromise the SEO of the page.
- Keyword stuffing in meta tags
Another common mistake is “keyword stuffing,” or the excessive use of keywords in meta tags. This practice can be penalized by search engines and make the page less visible in search results.
- Unsupported tags
Some HTML tags are not supported by all browsers or have been deprecated in newer versions of HTML. Use of these tags can cause display and functionality problems on the page.
- Nesting errors
HTML tags must be nested correctly, that is, closed in the reverse order of the order in which they were opened. Nesting errors-that is, closing one open tag within another before the entire block has been closed-causes confusion for both browsers and search engines, compromising readability and accessibility of content, and can cause display problems and make code more difficult to read and maintain.
- Attributes not formatted correctly
Attributes must always be formatted correctly within the HTML tag. This means that they must be entered in the correct “attribute=”value“” mode, using quotation marks to enclose the value. Many times, missing quotation marks or incorrect formatting can cause the browser to misinterpret the attribute correctly, causing display errors.
- Overuse of div and span elements
Although the <div> and <span> tags are essential for structuring content and applying CSS, excessive or unnecessary use of these elements can make the DOM too complex, slow down the site, and complicate code maintenance. This type of issue is often referred to as “divitis.” To avoid overuse, it is good practice to limit div and span tags to cases where equivalent semantic tags are not available (e.g., use <section>, <article>, <header>, <footer> instead of <div> when appropriate).
- Insert text outside of tags
Writing text outside of HTML tags, perhaps by mistake or distraction, results in that content not being interpreted correctly or, worse, being displayed in an unintended way on the page. Ensuring that all content is enclosed in the appropriate tags is essential to maintain code order and cleanliness.
Ultimately, inserting HTML tags into your site is a process that requires care and precision, because you have to open and close each tag correctly and make sure they are placed in the right place within the code. Errors in writing HTML tags are not only a sign of poor understanding of the language, but can have a direct impact on site usability, SEO performance, and the overall reputation of our online project. Maintaining attention to detail, scrupulously checking the code, and adopting the best practices dictated by web standards will allow us to avoid most of these issues, providing our users with a top-notch visual and functional experience.
Fortunately, with a little practice it will become a natural skill, and the text editors of CMSs make it markedly easier, because they allow us to manage all these parameters with simple buttons, without manual work in the code.
What are the most common and most commonly used HTML tags
Small but powerful, HTML tags are thus somewhat of road signs that guide search engines and users to find their way through the maze of code that brings a site to life, giving shape and color to the text on a web page.
There are hundreds of HTML tags that we can use to shape content, and it’s easy to feel overwhelmed by the sheer quantity-that’s why we generally divide HTML tags into a few broad categories, each of which serves a specific purpose in building and displaying web pages.
- Structuring Tags
These are the tags that allow you to define the structure of a web page. Some examples include the <div>, a generic tag that creates a “division” or “container” within the page, and the semantic tags introduced with HTML5 such as <header>, <footer>, <article>, and <section>, which help organize content into understandable sections, both for search engines and for screen readers intended for accessibility. - Text Formatting Tags
These tags allow you to control how text is displayed within the page. For example, <p> creates a paragraph of text, <b> or <strong> apply bold formatting, while <i> or <em> apply italics. These tags are critical to ensure that the content is readable and well-organized for the user, but also to highlight keywords for SEO purposes. - Linking and Anchor Tags
Closely related to navigation, tags such as <a> (anchor) are used to create hyperlinks, both internal and external. This tag is central not only to the usability of the site, but also to establish the structure of the site’s information architecture and links between pages, crucial aspects in SEO. - Multimedia Tags
With HTML5, specific tags have been introduced or improved to handle media of various kinds within pages. Prime examples are <img> for images, <audio> for audio files, and <video> for videos. These media tags not only make the site more interactive and engaging for users, but also contribute to SEO optimization when accompanied by appropriate attributes such as alt. - Tags for Forms and Input
One of the most essential categories for user-server communication is the form tag. The <form> tag allows the creation of data collection forms. Within it, we find tags such as <input> for collecting user data, <button> for submitting, and <select> for creating drop-down lists. With these tags, we can analyze user behavior and gather valuable information. - Meta tags and SEO
Meta tags are included in the <head> of the web page and are not directly viewed by users. However, they are crucial for search engines that read their content. Tags such as <title>, <meta name=“description”> and <meta name=“keywords”> provide crucial information that improves the visibility and findability of the page in search results. - Commentary Tags and Debugging Tools.
Finally, we must not forget tags such as the <!– comment –>, which are not visible to users, but allow developers to add explanatory notes in the code. These are especially useful when working in teams or having to come back to a project after some time.
For the purposes of our work, we have further broken down the tags and identified the most common and useful commands that we can best master to optimize our pages.
- The basic HTML tags
<!DOCTYPE> defines the document type.
<html> represents and defines the header of the HTML document.
<head> contains all the elements that describe the document.
<body> encloses the content of the web page.
<div> designates the paragraphs of a document.
<style> accommodates CSS codes that define the appearance of the website,typing the code directly into the HTML file.
<title> specifies the title of the HTML page, which is displayed in the title bar of the browser.
<p> is used to format text as a standard paragraph or main text: everything between the opening <p> tag and the closing </p> tag is displayed as a paragraph.
<br> with this tag you insert a space to wrap, activating a single line of space.
- Formatting tags (they affect text or fonts and work on everything between the opening tag and the closing tag </ >).
<h1 – h6> define the hierarchy of content headings.
<em> is used to emphasize a particular text in a paragraph, making the text italicized (same task as the <i> italic tag, but this has been deprecated with HTML5).
<b> makes text bold.
<u> allows text to be underlined.
<li> allows content to be placed in order in the form of a list. There are two types of lists: the ordered list <ol> and the unordered list <ul>.
- Link tags (for links within HTML documents):
<a> determines the hyperlink to another page, and the href attribute is used to define the link
<link> creates the link between the document and an external source.
<nav> creates links for navigation.
- Tags for embedding resources in content.
<img> is used to embed an image in an HTML document and requires the mandatory specification of the source of the image within the tag.
<map>, allows a map to be embedded in the document.
<audio> to include audio content.
<video> allows us to add video content.
<iframe> is used to embed content external to our pages.
<table> is used to create a table in the HTML document; the tag (<tr>) is used to create the rows of the table, while (<td>) is used to insert data into the table.
Why it is important to know HTML tags
Every text, image, video and every element we wish to include in our site is structured through HTML tags. Knowing and mastering these tags is not only a necessity for developers, but also an essential skill for anyone working with the Web, such as SEO professionals and content creators. Indeed, correctly understanding the meaning and use of the various tags allows us to ensure that our content is not only visually pleasing, but also well-structured and easily indexed by search engines.
Today more than ever, technical SEO plays a crucial role in determining the online success of a project. A website may be rich in quality content, but if HTML tags are not implemented correctly, it risks not being considered by search engines as it deserves to be. For example, careful use of the <title>, <h1> and meta tags can make the difference between a page that ranks on the first page of search results and one that does not appear at all. Proper use of HTML ensures that search engines clearly understand what each page is about, greatly improving click-through rate (CTR) and organic ranking.
But it’s not just about SEO. Accessibility is another crucial point, and well-structured HTML tags ensure that content is accessible even to people with disabilities, such as those who use screen readers. For example, the appropriate use of attributes such as alt for images not only strengthens search engine indexing, but also ensures that even visually impaired users can better understand the page content.
In addition, a good command of HTML tags allows us to be more flexible and quicker in web project management. When we know exactly which tags to use and how, we can resolve issues more quickly and prevent errors that could prove harmful in the long run. This is especially useful in a context where speed of development often goes hand in hand with the need to create responsive web pages that adapt to different devices.
Simply put, knowledge of HTML tags is like web literacy: without it, we are limited in our ability to create, manage, and optimize digital content.
HTML tags and SEO, how to use them appropriately
HTML is the cornerstone of the Internet, it defines the structure of the Web site and brings our pages to life, and tags are part of HTML markup: these small code snippets play, as mentioned, a crucial role in SEO as well, because they highlight parts of the content that are relevant to search and describe those elements for search crawlers.
Although perhaps the weight of such elements has waned somewhat in recent years-artificial intelligence and algorithms have made great strides in understanding content, for one thing-the link between HTML and SEO is still strong, however, making on-site optimization, which requires a deep understanding of language and HTML skills, a crucial step in the website creation process .
This is true for two reasons: first, there are still considerable margins for error in the automated work of crawlers, and HTML tags still have a crucial task in making sure that all our content is interpreted in the right way. Moreover, these tags are not only used to help search engines understand our content, because they can also improve the user experience, create preview snippets, solve duplicate content problems, and apply crawling rules.
Understanding the value and structure of a tag is essential if we want a web resource to reach the first page of search results, and when we talk about SEO HTML the focus falls precisely on tags, which are essential for building a logical and hierarchical structure of content, allowing it to be displayed properly on the browser screen.
Writing well-argued content that is valuable to users and search engines is only one part of the equation, because the other part is the ability to effectively use HTML tags and meta tags to give semantic meaning to our content, improving its visibility on Google. An incorrectly written tag is like an actor forgetting his lines: not only does it not contribute to the performance, but it can also ruin the whole show, making the text unreadable.
What are the main HTML tags for SEO
That said, not all HTML tags carry the same weight nor is it necessary to use all these extra code tools.
However, there are some elements that, when used properly, can greatly support our optimization efforts, as they help search engines understand the structure and content of our site.
First, we need to know and master the HTML tags that provide semantic structure to our website: tags such as <title>, <h1>, <h2>, <p>, and <img> tell search engines which parts of our content are titles, subtitles, paragraphs, or images, and this makes it easier for them to understand the context of our content and determine its relevance to user searches.
In addition, meta tags provide direct information to search engines, and we know, for example, how useful and when the description meta tag is used to provide a brief summary of our page content, which search engines can use to create the excerpt that appears in search results.
Finally, the proper use of HTML tags can improve the accessibility of our website: for example, the alt attribute in images provides a textual description of our images, which can be used by screen readers for people with visual impairments.
