SheerSEO

While the tool is still young and warrants attention, its interface could be polished as it's not particularly intuitive. Adjustments will definitely be necessary. It's functional at the very least, so I recommend it.

In my current case, I have a limit of 150 keywords, which I find very low. I recommend the company revisits the number of keywords tracked for all users who have purchased this product.

The support does exist, even if it lacks responsiveness; they were able to solve a problem.
