SEOTESTING is connected to your Google Search Console and presents different KPIs as you like. You can also create custom reports to gain more information about low-hanging fruits or opportunities.
But the best part, is that you can create SEO tests in 1-2 mins and can monitor your changes. It is very easy setup and can be done as single, group or even split-test.
