The science of enhancing a website to make it more visible when people search for goods or services is known as SEO (search engine optimization).
The positioning of a website on search engine results pages, often known as its ranking, is a typical metric for determining website exposure (SERPs).
Businesses continually compete for the top page since that is where visitors are most likely to pay attention.
Every page of a website is crawled by search engine bots, who then take the data and store it in a collection called an index.
The search engine acts as the librarian when someone searches this index, which resembles a library. The search engine collects and shows pertinent data from the search query.
Search engine algorithms look at the websites in the index to determine which sites should be shown in what order on the SERP.
