AMP stories are just like other web pages in the sense that they have a URL on your web server, they are linkable, and they can link out to other web pages.
Flavio Palandri Antonelli, a Software Engineer at Google, states:
“In particular, just like other pages on your site, make sure your Stories are linked from within your website so that your users and bots can actually discover them. If you are using a sitemap, make sure to include your Stories in that sitemap. If you are posting your regular web pages to social media, post your Stories as well. We could go on here, but the gist really comes down to: Follow the best practices you’re already applying to the rest of your website.”
AMP stories should be optimized like any other page on your website. What works for regular web pages will also work for AMP stories
With that said, there are some SEO tactics specific to AMP stories that can be utilized as well.
