The best part of this software is its ability for me as an advertiser or webmaster owner to be able to track my website performance in real time with all other sites being tracked by it! I can see what keywords are bringing traffic into our site which helps us know where we need improvement so far from SEO perspective but also how well each page performs compared to others within same category. It's not free version available at least yet (as per March 2020). We have been using follow click since 2016 now after few years i realized there should be some improvements done like better UI/UX design etc instead just adding more features here & there without any major changes made over last couple year only. So please try out if you're serious about your business then go ahead otherwise stay away because they don't deserve money unless their service really worth while providing value added benefits than basic advertisement toolkit provided by google itself. Tracking keyword related data has become much easier through use of such.
