A little passion for search engine optimization seo
It all started in mid 1990's when Webmasters and content providers began the optimization process of sites for search engines. Earlier what happened was that webmaster's job was to submit a page, or URL, to the various engines which would allow a spider to "crawl" that page, get the links to other pages from that page and get the information on the page which was to be indexed. This was a two step process where the spider after "Crawling" the page would save the information on search engine's own server where a second program known as the indexer would extract the relevant information from page. For crawling at later date the data was saved in a scheduler. Website owners recognized the value of the benefits a highly ranked and more visible site in a search engine generated.
