ads.txt Redirect Breaks AdSense Verification
AdSense reports ads.txt as missing even though browsers load it fine. The crawler refuses 3xx redirects; host the file at the canonical root with a direct 200.
💰 AdSense Approval & Ads Delivery Issues
Rejections, low value content, ads.txt, Auto Ads placement, blank slots, duplicate-site confusion, privacy policy, static-site ad slots.
"Site needs review" and "no ads available" are the two biggest AdSense traps for indie sites. This hub breaks down review states, common rejection reasons, blank ad slots, missing ads.txt, duplicate-site confusion, incomplete privacy policy, weird Auto Ads placement, ads slowing the site, and manual ad units failing to render on static Astro / Firebase / Vercel sites. Core message: technically correct ≠ ads will run; more pages ≠ approval; "no ad" is usually review + fill rate + policy + delay + script + environment combined.
Common problems
- AdSense low value content rejection Not about length — about unique value & intent.
- Site needs review for too long No SLA — check crawlability while you wait.
- Ads not showing after approval 24-48h delay + fill rate + policy.
- No ads available on some pages Page content, advertiser demand, region.
- Ad script installed but slot remains blank data-ad-slot / display width / async load.
- Auto Ads appear in poor places Anchor regions + restrict types + blocklist selectors.
- Ads slow down the website Lazy-load + reduce slot count.
- Privacy policy missing or incomplete Must cover third-party cookies and AdSense.
- Cookie consent for ad-supported sites EU users need CMP; elsewhere depends on policy.
- ads.txt not found or delayed Must be reachable at root, ~24h cache.
- AdSense approved but site still pending Account ≠ per-site; each site is separately reviewed.
- Many pages but still too thin for review More pages ≠ more unique value.
- Content site monetization before enough traffic Review doesn`t need traffic but needs trust & value.
- Ads show on homepage but not article pages Template diff / article length / slot code.
- Duplicate site / domain confusion during review Same content on multiple domains tangles review.
- Manual ad units not rendering in static sites Common pitfalls on Astro / Next static exports.
- AdSense invalid traffic warning Check category + appeal with evidence + Cloudflare Bot Fight.
