The term "search engine optimization" refers to the process of optimizing a website for search engines. In basic words, it refers to the process of enhancing your website in order to improve its exposure when consumers use Google, Bing, and other search engines to look for goods or services relevant to your company. The higher your pages' exposure in search results, the more likely you are to draw attention and attract new and current consumers to your company.
Bots are used by search engines like Google to crawl the web, traveling from site to site, gathering information about those sites, and indexing them. Consider the index to be a huge library where a librarian may bring up a book to assist you in finding precisely what you're searching for at any given moment.
Then, using hundreds of ranking variables or signals, computers evaluate sites in the index to decide the order in which they should show in search results for a particular query. The librarian in our library example has read every book in the library and can tell you which one will contain the answers to your queries.
Google uses authority to determine whether or not a piece of information is factual and trustworthy. But how does Google determine whether or not a page is authoritative? They consider how many other sites connect to that page. In general, the higher a page's ranking, the more links it has.
Relevant and authoritative content is possible. However, if the information isn't helpful, Google won't want to put it at the top of the search results. Indeed, Google has said that there is a difference between "better quality material" and "useful" information.
