Where does SEOMoz pull it's keyword data from?

[FilterEasy]

I would like to know where the data in the keyword recommendation tool comes from.  Specifically, from what sources is SEOMoz referencing to compile the keyword recommendations and analysis?

Thanks!

Hey there! Tawny from Moz's Help Team here!

Where we're getting keyword suggestions from depends on which tool you're using. For Moz Pro, the suggestions come from our own data and data from a third party, Similarweb. For Keyword Explorer, the suggestions are based on our own database of millions of keywords.

I hope that helps, but if you've still got questions, feel free to shoot us a note at help@moz.com and we'll do our best to sort things out for ya!
