Probably one of the best products on the market for getting deeper insights on Google Search Console data
Great tool that taps into Google search console. Lets you run SEO Split tests and shows keywords within the 'striking distance' Love it!
Really nice and easy product to use for keyword tracking. But the benefits are in the other features
We've been using it on our agency site for the past few months. It's been a great help in drilling down into areas we can improve and as such we have seen improvements across the board in our SERPS
I don't use it to it's full potential (yet) but get loads of value out of the features I do use
Hands down, SanityCheck is the highest value SEO tool that we use (and pay for). It's simple to use, and highly effective at surfacing "low hanging fruit" on a regular basis. By addressing the issues and opportunities that SanityCheck brings up, we're able to steadily improve our SEO while juggling everything else.
It is a simple to use yet highly effective tool. I have used it for strategic SEO growth around high value key word rankings since it launched and it has really paid off. I am a paying customer btw :-)
But you can look the early stage of this product as an advantage - plenty of interesting directions to go in. The developer, Nick, seems to be interested in feedback, and is actively developing new functionality. He's interested in use cases, jobs to be done, not just adding another feature.
