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. | Many websites are added each day to the Internet.

A search engine 'crawls' or 'spiders' the web based on what is already there. If a new link is added somewhere, 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. | |||
