How to Find and Check AdSense Code on Your Website: Verification Guide [de]

The Role of the AdSense Code Snippet

When you apply for Google AdSense or submit a new domain for review, Google asks you to perform a critical step: connect your site. To complete this connection, Google provides a small asynchronous JavaScript snippet that must be placed in the HTML <head> section of your website.

This script serves two primary functions. During the review stage, it acts as an automated site ownership verification beacon. When Google’s review bot (Mediapartners-Google) visits your domain, it looks for this tag to confirm that you actually control the website. Later, once your site is approved, this same script powers Auto Ads and delivers display banner creatives across your templates. If this code is placed incorrectly, stripped by caching plugins, or deferred improperly, your review will remain stuck in "Getting ready..." indefinitely.

What the Standard AdSense Code Looks Like

The standard modern Google AdSense loader tag is lightweight and asynchronous. It typically looks like this:

<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-0000000000000000"
     crossorigin="anonymous"></script>

Notice the client=ca-pub-XXXXXXXXXXXXXXXX parameter. That parameter contains your unique AdSense publisher client ID. If this parameter is missing or contains placeholder zeros, Google cannot link your site to your account.

3 Methods to Verify AdSense Code on Your Website

Method 1: Inspect Page Source Code in Your Browser

The most straightforward method to confirm the script is physically present in your HTML response:

1. Open your website in Google Chrome, Mozilla Firefox, or Microsoft Edge.
2. Right-click anywhere on the page and select View Page Source (or press Ctrl + U on Windows / Cmd + Option + U on Mac).
3. Press Ctrl + F (or Cmd + F) to open the in-page search bar.
4. Type pagead2.googlesyndication.com or adsbygoogle.
5. Verify that the script tag appears between the opening <head> and closing </head> tags, and confirm your publisher ID matches your dashboard.

Method 2: Use Browser Developer Tools (DOM & Network)

Sometimes caching plugins or tag managers inject scripts dynamically via JavaScript. To check if the script executes in the live DOM:

1. Press F12 or right-click and choose Inspect.
2. Click on the Network tab in Developer Tools.
3. In the filter box at the top, type adsbygoogle.
4. Reload the page (press F5 or Ctrl + R).
5. Look for a successful network request to adsbygoogle.js returning an HTTP 200 status code. If the request shows in red with a status like (blocked:other), an ad blocker in your browser is active—disable it and test again.

Method 3: Run an Automated Audit with Rankzio

Instead of manually inspecting multiple pages, enter your website into Rankzio’s free AdSense Readiness Checker. Our automated scanner inspects your raw HTML response and reports whether the official AdSense client script tag is detected, giving you immediate visual confirmation.

Common Code Placement Mistakes

1. Placing the Code Inside the <body> Instead of <head>

While ad unit display containers (the actual ad banner boxes) belong inside the <body> where you want ads to render, the primary site verification loader script must reside inside the <head>. Placing it in the footer or body can cause review bots to miss it during automated scans.

2. Aggressive JavaScript Minification or Deferral

Performance optimization plugins (like WP Rocket, Autoptimize, or LiteSpeed Cache) frequently offer options to "Defer All JavaScript" or "Delay JS Execution until User Interaction". If your plugin delays the AdSense script until a user moves their mouse, an automated Google review bot—which does not perform physical mouse movements—will never see the script fire! Exclude adsbygoogle.js from JavaScript delay rules during your application review.

3. Forgetting Staging vs. Production Differences

If you build your website on a local environment or staging subdomain (e.g. staging.yourdomain.com), ensure the code snippet is copied over to your live production domain before submitting to Google.

Summary Checklist for AdSense Code Verification

• Script tag located between <head> and </head> on homepage.
• Contains valid ca-pub-XXXXXXXXXXXXXXXX publisher identifier.
• Network request returns HTTP 200 in browser Developer Tools.
• Script is not delayed or stripped by performance/caching plugins.
• Ad blocker disabled when testing live rendering in your browser.
