Best Search Engine Submission Search engine works by sending out a spider to fetch as many documents as possible. Another program, called an indexer, then reads these documents and creates an index based on the words contained in each document. Each search engine uses a proprietary algorithm to create its indices such that, ideally, only meaningful results are returned for each query. It searches your site for words that describe your page and index your page based on how many times such words are used on your page. For instance if your page is about "hosting", the search engine will index your site and keep it until someone searches for "hosting". It will pull up your site and every other site that have hosting mentioned in their text. However, to have your site on top of other sites will certainly get you more "hosting" interested visitors than other sites.
