There are numerous and plentiful stat sites for your own affiliate sites or if you’re interested in seeing where your competitors are gaining or sending traffic.
However, a site we’ve been really enjoying lately called SimilarWeb has been insanely helpful for all things stat-related:
SimilarWeb – About Us: “The source of our data is the accurate collection of clickstream data from internet users all over the world. Unlike some providers who focus on a specific region or user type, our collection is done on a global scale, with a statistically representative cross-section of all types of consumers. This allows us to reach unbiased, all-round understanding of a website’s traffic.”
For instance, here’s ReveNews’ entry on SimilarWeb.
You get the point.
This is fun and very helpful. Go and enjoy this awesome free tool.
