I have the start of an amp site and I am looking to take advantage of Google AMP Cache. I understand the instructions of generating cdnAmpURLs and I can see that I should use them to prefetch content such as fonts and images but what I don't understand is where to use them for maximum benefit.
Do I:
- Use them on my canonical pages?
- Build a specific sitemap.xml of them?
- Use them in advertising?
- Provide them to external link providers?
- Replace relative path URLs internal to my site with them?
I just don't get that bit, any pointers would be greatly appreciated.
