Search Engines for Genealogical Research

Although Google is the most widely-known and comprehensive search engines for locating genealogical information at present, many other search engines are also useful. The fierce market competition between the better-known search engines should only serve to make genealogical research easier.

Many websites are added each day to the Internet. If you have searched for information on an ancestor more than 60 days previously, it is worth searching again. The information changes at an amazing rate on the Internet. Websites with frequent changes often get updated in the search engines daily, if not every week or two.

A search engine 'crawls' or 'spiders' the web based on what is already there. If a new link is added to a website somewhere, and it is not already in the search engine's database of sites it searches, the search engine will go to that link and 'spider' it for its contents and add the page or entire site to its database, index its contents, and make that site's contents available for searching by way of the search engine. This can happen anywhere from once a month to daily depending upon how frequently that site is updated.

No two search engines contain the exact same database. Any one search engine may contain listings of sites that another search engine has missed. So if you do not find an ancestor in one search engine, try another, or better yet, try a compiled search engine, or 'metacrawler'.
