Since version 5.5, WordPress has a built-in XML sitemap. Any newly published content will automatically be in that sitemap — including any web stories you create! The same goes for XML sitemaps added by plugins like Yoast SEO.

Another way for crawlers to find your content is by linking to it, for example by embedding the story in a blog post using the dedicated Web Stories Embed block.
