Genealogy In Time Magazine gives us an article about the 100 most popular genealogy websites that is a great read.
The article explains the methodology used to come up with the list, and then gives you the following information on each site: rank, website name, category, country, free or pay, Alexa traffic rank, website address.
The article concludes with several insights gained from the survey. For instance, genealogy forums are the second most popular category; three genealogy society websites made the list; and more than half of the top 100 are free.
If nothing else, this is a good article to read just to be sure there is not a website out there that you are not aware of, but which can help with your research.
