TL;DR: Most indexing problems come from one of these: the page is blocked, set to noindex, hard to discover (no internal links), or the content is too thin/duplicate.
Open the URL in an incognito browser. If it doesn’t load, Google won’t index it.
If a page is set to noindex, Google can crawl it but won’t add it to search results.
Robots.txt can block crawling entirely. If Google can’t crawl it, it can’t index it.
If your page’s canonical points to a different URL, Google may treat the other URL as the “real” one and ignore this page.
If nothing links to your page, Google may not find it quickly (or at all).
If your page redirects multiple times, or if both http/https or www/non-www versions exist, indexing can get messy.
If the page is very short, near-duplicate, or doesn’t add value, Google may crawl it but skip indexing.
