In the beginning, the search engine optimizer algorithms were dependant on the keywords, Meta tags, and index files provided by the Webmaster. Meta tags provided information about a particular page, but using them for indexing the pages didn’t prove to be successful as some Webmasters added irrelevant Meta tags to increase the number of hits and earn huge ad revenue. They even changed the HTML of the web pages to achieve a good rank for the page. But this was a case of abuse as it fetched irrelevant pages.
