If you search for “alternative to google reader”, within the top few results is alternativeto.net, a user-voting style site to rank alternatives to products. I use the site a lot to find obscure alternatives to products I’ve grown out of.
In the past month, there have been 58,799 visits, with 539 of those coming from alternativeto. That’s competing with all other referral sources, such as press, and all direct traffic, which is all returning visits. So 1% of the total is more like 4% of all referral traffic. I’d say that’s pretty good!
