I spent yesterday creating an AMP portion of a website and it was a pain, I got it to a decent state but when I ran performance tests it wasn't that much better but the usability seemed to suffer. I'm not sure if it's worth it. The website's sole business purpose is to succeed in SEO so that's why I thought it might be worth doing (if it sends a signal to google). Since non-amp and amp are already getting high marks and loads very fast I rather not include amp if doesn't actually increase SERPs. If someone knows the facts here I'd love to know because I scrapped it and would prefer not to look back.
