Search engine optimization
On-page SEO is still practiced by web owners and web development agencies. Websites are ranked by content and use Google keywords  to index websites and rank accordingly. In fact, Google’s own “How Search Works” reported that, “The most basic signal that information is relevant is when a web page contains the same keyword as the search query. If those keywords appear on the page, or if they appear in the headings or body of the text, the information is more likely to be relevant”.
