Google Alerts lets you automate your Google genealogy queries, sending you an email whenever any new content about your query is added to the Google index. This makes it easy to keep up with your Google genealogy searches and not miss any new sites without having to perform the same Google searches over and over.
Create a set of keywords, and Google Alert will run a search each day, and automatically send you an email alert when the query produces *NEW* results. So before taking advantage of the Google Alerts, you will want to first run the query in Google to thorougly examine all the old results.
You can use all the advanced search features that Google offers such as quotes, math signs, etc, as you would in a regular Google genealogy query. To take full advantage of Google Alerts, you can learn about advanced Google search features for genealogists at Google Hints and Tips for Genealogists .
I’ve been using Google Alert for a while now and have been pleasantly surprised at the results. Not only have I found previously unknown Web Pages that fit my query, but I have also found archived Rootsweb mailing lists that I never would have thought of searching.
You can set Google Alerts to perform a search once a day, once a week, or as it happens. You can search the Web, Blogs, Groups, News or Comprehensive (all). I have been using Comprehensive, but most of the results I get are from the Web.
You can search for your surnames, or ancestral town, or whatever, whomever, and wherever you are researching. With unlimited alerts allowed, you can set up an Alert for individual people in your database. You can search for records you hope someday may be transcribed and put on the web.
