Keep indexable content out of iframes, and check web components in the rendered HTML

Google generally tries to index iframe content as part of the embedding page, but that is not guaranteed because both are normal pages of their own. Google flattens shadow DOM and light DOM when it renders web components, and content that does not appear in the rendered HTML cannot be indexed.

Put the main content in the page's own DOM and use iframes for third-party widgets you do not need indexed. For web components and micro-frontend libraries that patch browser APIs, verify the result in Google's tools rather than trusting a library's promise of indexability.
