The second article in the search engine optimization series on SEO Profile is How Search Engines Work. This is an article for beginner SEO’s and people wanting to learn more about search engine optimization. Here is a small excerpt from the article.
Once the user performs the search, the search engine returns a results page showing all the pages in its index that it considers a match for the search terms. The search engine will rank the results by relevancy, providing the most relevant results at the top of the list. The search engine will find all the documents containing the words the user searched for and return them in a list to the user. The search engine determines which documents are the most relevant by counting the number of times the words appear together within the document. Additional factors considered include the placement of the keywords within the document.
