You mean Checkbot is confirming your pages should be indexable as you expect but the pages aren't turning up in Google?

Some general suggestions: add a site map, submit your sitemap and pages via Google Search console, see if changing the internal linking of pages helps (e.g. pages that have links in the header/footer will seem important to crawl/index, maybe hubs for or "related pages" links for related pages would help), get more (and better quality) backlinks, and make sure pages don't look like duplicates (as Google will group together repetitive pages).

Yes that's correct. Regarding your suggestions - thank you! I've done three of the four but still missing back links. We do have 1000s of pages that have a very similar structure, so I would understand why Google would mark them as duplicates, but the content on each differs, so I'm hoping that's not the case.
