I Built a Free AdSense Audit Tool — Here's What It Actually Checks (And Why Most Sites Fail)

If you've ever wondered why your AdSense application got rejected — or why your
existing account keeps getting policy warnings — the answer is almost never "bad
content." It's usually something invisible: a missing privacy policy, a
misconfigured robots.txt, or a page structure that automated reviewers flag before
a human ever looks at it.

I ran into this problem with a client site. Clean content, decent traffic, but
rejected twice. So I started auditing manually — crawling pages, checking headers,
verifying policy pages, testing mobile rendering. After doing this a few times I
built a tool to automate it.

That tool is now live on ToolzPedia: https://toolzpedia.com

Here's what it actually checks.

What the audit covers

Crawlability
The tool checks whether your robots.txt is blocking Googlebot and the AdSense
crawler. A lot of staging configs get pushed to production and lock out crawlers
entirely — your site looks fine to humans but invisible to Google.

Privacy policy detection
AdSense requires a privacy policy that covers cookie usage and data collection.
The audit scans your footer links and page content for a valid privacy policy URL.
Linking to a generic template on a third-party domain usually fails this check.

Content quality signals
Thin pages, doorway-style URL structures, and low word counts are all flagged.
The tool estimates content density per page so you can see where you're below
the threshold before Google does.

HTTPS and security headers
Running on HTTP in 2025 is an automatic rejection. The audit also checks for
basic security headers since some reviewers now flag their absence as a trust signal.

Mobile usability
AdSense policy has tightened on mobile experience. The audit checks viewport
meta tags and basic responsive structure.

Ad placement rules
If you already have ads running, the tool checks for known placement violations —
ads too close to navigation, ads inside article tags that push content below the
fold, and interstitial-style placements on mobile.

Why most sites fail

In my experience auditing sites, the three most common rejection reasons are:

Privacy policy either missing or not linked from every page
robots.txt accidentally blocking the AdSense crawler
Content that's technically original but too thin per-page (under ~300 words)

None of these are hard to fix. They're just invisible without a structured audit.

How the tool works

It's a Node.js crawler running on a VPS, with a PHP front-end. You enter your
URL, the crawler fetches your pages and runs them through a set of checks, and
you get a scored report with specific fixes.

Free accounts get a one-time audit. If you want to run it monthly or track
changes over time, there's a paid tier.

If you find something wrong with the audit results or have a site it doesn't
handle well, drop it in the comments — I'm still actively improving the checks.
