Our main root domain for our PWA is here:
The main editor page (and some previous versions) keep being de-listed as a "Soft 404". This removes the root domain from search results completely (and site:editor.construct.net) results.
All old versions point their canonical URL to the main root domain.
I am 99.999% sure the URL's don't respond with a 404 (all content is static, behind Cloudflare and we receive no user reports of difficulties accessing the PWA), which leads me to believe Google is delisting for thin content.
We have a tag on the editor page that has links and a little bit of content with the goal to pass link juice to our main website. For technical reasons, we cannot have HTML content outside the tag.
Does anyone know what we could do to stop Google delisting our PWA as a soft 404?
