Shop Sheriff AMP Pages

Excellent App. Having AMP pages seems to be more important than ever since Google went to Mobile-first indexing. Our rankings went up immediately. Awesome customer support: so much better than a big impersonal company.
Very easy to implement: you don't need to know anything about AMP etc. It didn't render some of our custom pages very well, but it was easy to simply unpublish those on a case-by-case basis. Big fan of this app and this company.
