Indexing
Indexing is a crucial stage in a search engine‘s work process, following the crawling or crawling phase and preceding ranking.
During indexing, the information gathered by search engine crawlers is analyzed and organized into an index (hence the name), which is a kind of giant database of content found on the Web. This index is then used by search engines to provide quick and relevant results when users perform a search.
Indexing takes into account various factors, such as page content, site structure, metadata, keyword usage, and many other signals to determine the relevance of a page for certain search queries.
Not all scanned pages are indexed; for example, and as a general rule, search engines may decide not to index pages with duplicate content, low quality content, or those that do not meet the guidelines for ethical SEO.
