[AMP Pages] AMP Pages Pros and Cons

Hello,

We need help!
What are the benefits and what are the drawbacks to switching to AMP pages?

The website is with good ranking in Google. With AMP pages the aim is to make the site load faster on mobile devices. At present the site loads slowly due to extensive number of images, the current site size is circa 12GB.

There's Yoast SEO installed. We plan to use Glue for Yoast SEO & AMP plugin to make AMP and Yoast work together, but we are open to suggestions.

Can you think of a way to test the setup in advance?

Thank you!
