Look at the Google and SEO RelationshipWith the launch of the Google search engine, the SEO process became more complex. It was developed to ensure better and more accurate indexing as well as identify the misuse of search engine optimization tactics such as keyword stuffing, which refers to including irrelative keywords in a web page to mislead the search engine crawlers.
