I have no idea how this plugin has any positive reviews

I never got a single reply from the developer while using the free version of Booster so we bought the paid Booster Plus and still can’t get a reply to multiple support requests!

I can only assume that the majority of the high reviews are completely fake. If you’re contemplating using this plugin be forewarned that it DOES NOT WORK with Yoast SEO and if you have any questions for the developers, you’re out of luck.
