Here are some common factors to consider:
Technical Issues: Check if your robots.txt file is blocking search engine bots from crawling your pages, or if you have any noindex meta tags that might prevent indexing.
Content Quality: Likely the biggest culprit we see as to why your pages aren't indexed. If your content is considered duplicate, thin, or low-value, it may not meet Google's quality threshold for indexing. Pro tip: Make sure you have enough content to give Google context for the page and don't forget your internal links with proper anchors!
Crawl Budget: For larger sites, you might exceed Google’s crawl budget, leading to some pages remaining unindexed.
Outdated Content: If your content is outdated or not regularly updated, it may lose relevance and thus not get indexed.
Technical Errors: Issues like broken links, server errors (like 404s or 500-series errors), or excessive redirects can also hinder indexing.
Lack of Backlinks: If your site has few or no backlinks, search engines may not trust your content enough to index it.
Also, it is very important to note that indexing is never automatic (it is a process) and is certainly never guaranteed. In fact, a recent study in April 2025 showed that approximately 62% of all pages NEVER get indexed. Even those that do, ~14% of them fall out of index status within 90 days.
