MetaCrawler queries the other search engines, organizes the results into a uniform format, ranks them by relevance and returns them to the user. This means that MetaCrawler is more likely to obtain accurate results for your search query. The right search engine for you is the one that finds more of the information you want, and the one you're most comfortable using. Each engine has a different database, so each will have a different result. You may find that for a particular subject, one search engine is better than another.
Some search engines provide excerpts from the Web pages they locate.
These excerpts can help you decide whether to follow a link. Other engines display only the link. Still other search engines give you the choice to see more or less detail about the pages located. Once you have identified which search engine is best for you, you may want to personalize your web search engine page. For example, imagine you are trying to find the web page of an old college friend Michael Jordan, not the Chicago Bull Michael Jordan but someone else by that name.
