AdSense Preflight runs the same technical checks Google uses during review. Catch the issues that cause "Site down" or "Low value content" rejections, fix them, and apply with confidence.
Access code required · 5 site checks per week · No signup, no email
Real signals from Google's own infrastructure — not vague generic advice.
Calls Google's real PageSpeed Insights API. Same Lighthouse engine Google uses internally for ranking signals.
Pulls Core Web Vitals from CrUX — actual performance experienced by real visitors, the data AdSense reviewers see.
Paste your access logs. The tool detects fake bots, zero-byte responses, and the exact patterns that trigger AdSense rejections.
HTTPS, viewport, robots.txt, auto-popups, vulnerable libraries — every technical check AdsBot-Google runs during review.
Auto-checks Wayback Machine to verify domain age — critical signal for the 2026 stricter approval rules.
Site signals + server signals = one final number. Above 85 means you're ready. Below means specific work to do.
Three steps. About two minutes.
You'll need a code to use the checker. Each code is good for 5 site analyses per week.
Enter your site URL. Optionally paste server logs from your hosting panel for deeper analysis.
Receive a 0–100 score with prioritized fixes. Address the high-priority items, then apply to AdSense.
The most common rejection. Triggered when AdsBot-Google gets a timeout, 5xx error, or zero-byte response when visiting your site.
How we detect it: Server log parser identifies zero-byte responses, fake bot traffic stressing your server, and 5xx error patterns — the exact issues that cause this rejection.
2026's stricter content rules. Sites need 15+ articles, 800+ words each, real author info, and original content.
How we help: We can't read your articles, but we measure structural signals — heading hierarchy, meta descriptions, image alt text — that correlate with content quality scores.
Catch-all for technical violations: HTTP without SSL, broken navigation, auto-popups, deprecated APIs, vulnerable libraries.
How we detect it: 21 specific Lighthouse audits flag every one of these issues with severity ratings.
No. It's an independent diagnostic that uses Google's public APIs. The PageSpeed Insights API and Wayback Machine API are public; everything else is open knowledge about the AdSense review process.
No, and we're honest about that. Google's content-quality classifier and human reviewer judgment cannot be replicated. But about 70% of rejections are technical or structural — and that 70% is exactly what this tool catches before you submit.
Codes are distributed by the operator of this site. If you don't have one, contact whoever shared this tool with you.
Site URLs go to Google's PageSpeed API and the Internet Archive. Server logs you paste are processed entirely in your browser — they never leave your device.
Google's free PageSpeed quota is finite. The 5/week limit ensures everyone with a code gets fair access without burning the daily quota.
