I have been using WebCEO for quite some time now and it's has got every tool and reporting feature you could need to master SEO, all in one place. In particular it's competitor insights are extremely useful for benchmarking purposes and understanding your position in SERPs. We would have preferred if there was an option between the Solo and Startup plans that allowed for more keywords. We found we wouldn't have needed all of the features in the Startup plan but could have benefitted from more keywords. However we are more than satisfied with the solo plan for now, it's still a fantastic tool
