Programmatic pages get deindexed for one of three reasons. Knowing which one applies saves weeks of debugging.

Programmatic pages get deindexed for one of three reasons. Knowing which one applies saves weeks of debugging.

1. Duplicate content — your templates aren't varying enough between pages. Google sees 500 near-identical pages and treats them as spam.

2. Thin content — each page exists but provides no genuine value. The data is there, but there's nothing for a user to actually do with it.

3. Crawl budget waste — you're generating pages faster than Google can process them. Thousands of low-value URLs drain crawl budget from your important pages.

Diagnose via Google Search Console coverage report + Screaming Frog crawl. If indexation rate is below 40% on a programmatic build, one of these three is the culprit.

Fix the root cause, don't just request reindexation.
