This is a review of the company RankSonic, not the product. RankSonic aka 4webmasters.org et al is a blight on the Internet with their spam tactics. Do Not do business with this firm. They Suck! The entire web operation is out of the Ukraine - good luck if you provide a credit card to them. I manage over 100 websites and 75% of them have 4webmasters.org spam hitting Google Analytics. I am glad that Google is working on taking down all of their web assets. Search Google for "stop referrer spam" for ways to fix your tracking metrics if you see 4webmasters.org or RankSonic in your Google Analytics.
