Diagnose why a page isn't getting indexed

[yourdomain.com/blog/best-vpn-for-streaming-2026/] was published 6 weeks ago,
submitted via GSC's URL inspection tool three times, and still shows "Discovered,
currently not indexed." It's 2,800 words, not thin content on its face, and links to
and from 4 other posts on the site.

Diagnose this the way Google's own documentation frames it, as a decision tree, not a
single cause:
1. Rule out hard blockers first: check robots.txt disallow rules, a stray noindex
   meta tag or X-Robots-Tag header, and whether the canonical tag on the page
   actually points to itself rather than to some other URL.
2. If no hard blocker exists, consider crawl budget and site-wide quality signals: is
   this a low-authority site publishing high volume, in which case Google may be
   deprioritizing crawl of new pages, versus a specific quality judgment on this one
   page.
3. Compare this page against the 2-3 similar posts that did get indexed. If it's
   near-duplicate of an existing page on the same topic (even a different URL),
   Google may be treating it as redundant rather than "not yet crawled," and no
   amount of resubmitting fixes that; the fix is differentiation or consolidation.
4. Check internal link depth: if this page is only linked from a single low-traffic
   archive page and nowhere else, that's a plausible discovery problem, and adding
   contextual internal links from higher-traffic pages is the actual fix, not
   repeated manual submission.
5. Give a ranked list of the 2 most likely causes given the evidence provided, and
   say what to check next if both turn out to be wrong.
