When beginning any type of online marketing campaign with any type of social media optimization involved you want to join the most effective social networks that you can find. So I decided to take a list that Traffikd had put together with a big list of social networks and see what type of traffic Compete estimated the sites had along with Google’s Page Rank.

Here are the results:

Top Ten Social Networks by PageRank

*Ranked first by Page Rank then by Compete.com to determine tie breakers. Full list of all 360+ can be found at Google Docs here and downloaded under File->Export.

Be sure to check all the sheets at the bottom of the document for the different sorted views. (All Data, Alphabetical, Compete (visitors), and PR)

We put our research online and available for the full report of rankings. There are over 360 social networks on the list. You can download it locally and use it as a checklist or however you’d like to consume the data. If you found this article useful share it with your friends, tweet it, digg it, or do whatever you can to spread this resource.

Some social networks didn’t make our list because they had so little data that Compete didn’t pick them up as having enough data. If you have suggestions for other social networks to add to the list let us know.
