I have purchased a number of SEO tools now through AppSumo still looking for a favorite, but SerpWatch is growing on me (fast enough I'm buying more codes). The user interface is simple, but I sometimes am not sure where to click (I click on the company project name and it goes to their website) However, after the learning curve, the display of what is offered is really nice, but the best feature is that when you set up a project, SerpWatch is very clear about how much of your "license" the monitored keywords are going to take, I REALLY like this.

One of the challenges with the sumo deals is worrying about using too much, I like SerpWatch does a great job of letting me know how much bandwidth I have. Looking forward to using the client portals in time.

Looking forward to integrating this tool more frequently with our small agency. I think we're off to a good start.
