Seo-cant detect h1 h2 tags

I’ve heard back from the Bubble team after they had reviewed the issue raised:

Some tests are not sophisticated enough to handle client side javascript generated pages. The header tag is being set, which you can see if you inspect the element. Thus, it is working with Google, etc.

As a few other posters had summarised, some tools simply don’t offer the ability to detect on-page tags.

Unfortunately a few premium tools I use to generate reports of pages do flag that there are missing H tags and alt tags, so in the reports these misrepresent the actual optimisations. But perhaps overtime as the web world landscapes shifts more to JavaScript, they will adopt better tech for scanning dynamically generated page schema.

Thanks for everyone’s input. Its an important subject and glad we’ve found a resolution.
