What AdSense actually tells you
When a site isn't approved, AdSense shows it under Sites with the status Needs attention and one or more reasons underneath. The same result usually arrives by e-mail, and site-level policy problems are listed in Policy center. Write the reasons down word for word before you change anything: they decide where to look.
The labels publishers see most often are Low value content, Site down or unavailable, Policy violations, Valuable inventory: Under construction, Valuable inventory: No content and Site navigation issues. Several can appear at once, and each one is broad: Low value content alone can mean thin posts, copied text, a mostly empty site or hundreds of near-identical pages.
Why technical causes come first
A rejection that reads like a content problem is sometimes a crawler that never saw the content. A Disallow line for Mediapartners-Google in robots.txt, a Cloudflare challenge, an expired certificate or a redirect loop on the www version all look the same from Google's side: the pages couldn't be read.
These are also the quickest to rule out. Each answer above lists the free checks that test them; each one runs in seconds and needs no account.
How the scan connects your reason to your site
The free scan reads the first pages of your site the way Google's crawlers do and runs the same checks as the full report. Started from this page, the report opens on its Issues tab with your reason already entered in the rejection decoder, which lists the findings that can explain it and how many pages each one touches.
The decoder matches Google's wording, it doesn't guess: when the scan finds nothing behind a reason, it says so. You can also paste the whole rejection e-mail there; it recognises Google's reasons in English and Turkish. Every check, and the evidence it relies on, is documented on the methodology page.
Before you click Request review
- Fix the cause first. An unchanged site gets the same answer, and Google says the review "usually takes a few days, but in some cases can take 2-4 weeks".
- Don't remove the site and add it again. Google: "Make sure you don't remove your site and resubmit it because this can delay the process."
- Don't open a second AdSense account to try again. Google allows one account per publisher, and a duplicate account is a rejection reason of its own.
- Look at your changes logged out and on a phone, the way a reviewer sees the site.
