I've been using SERank for over a year now and own a few other rage products. I've tried a lot of other seo products both downloadable and online. I have found SERank to be, by far, the easiest one to use on my Mac. Most other rank tracking products are built for Windows first, but SERank looks and works fantastic on my Mac!

The only one feature it is missing is scheduling. But because you can select all your websites and have it run in the background by itself, it's not the biggest deal.

I also, love the Google Analytics integration. It tells you how many visitors come to your site from each keyword. It's interesting to see when a well ranked keyword either brings you a lot of visitors or very little. Letting you know which keywords you should really be targeting and which you can forget about it.

Support has also been great!
