I've purchased dozens of different programs on appsumo. I usually end up using about 10-20% of them regularly, but there are only a couple which I actually have saved to come up every time I open my browser, and SEOCrawl is one of them. This is one of my most useful tools for running my agency. And I'm still finding things that I hadn't seen before, adding to the value. One of my top purchases. Well done!
