Page Speed
PageSpeed refers to the speed at which a single web page loads. Specifically, it measures the time it takes to fully load the content of a specific web page, encompassing both the full display of visible content (above-the-fold) and background processes (from-the-start-to-the-finish). It is therefore a different concept from that of site speed.
Page speed can be affected by various factors, including file size, server speed, and user bandwidth. In addition, the parameter can vary greatly from one page to another within the same site, based on elements such as the amount and type of content or the structure of the code.
Theoretically, a faster loading time improves the user experience and increases the likelihood that the user will interact with the page, reducing the bounce rate. In addition, pages that load quickly can maintain user attention, improve customer satisfaction, and ultimately lead to higher ROI.
However, there is no value, metric or standard to use to measure the speed of a web page-it is not like the speed of a car nor is it enough to think about the “faster the better” equation. Page Speed is more like looking at how long it takes a person to interact with a site and how comfortable they feel while doing so. Google has tried to simplify things by introducing Core Web Vitals, which are a set of measures that help precisely to understand how fast a web page loads and how easy it is for people to use it.
