Overview #

When a funnel is published on a subdomain (example: offers.example.com), Google Ads may reject the landing page due to:

• Circumventing Systems

• Compromised Site

• Final URL Mismatch

• Redirect or URL Loop Detected

This usually happens because the funnel has two different URLs that load the same page, such as:

• https://offers.example.com/

• https://offers.example.com/summer-deal

Google Ads sees this as a redirect or URL inconsistency, even though the page loads normally in a browser.

This article explains why it happens and how to fix it.

Why This Happens #

Funnels automatically include a step path such as:

But many users want the root version:

Both URLs point to the same funnel step, which can lead to:

• Two URLs → One page

• Google detecting a redirect or mismatch

• Google Ads rejecting the landing page

This is normal behavior in funnels, but Google needs one “official” URL.

The Fix: Add a Canonical URL #

A canonical tag tells Google:

“Both URLs are valid, but this one is the official version.”

Adding a canonical tag removes redirect-related disapprovals in Google Ads.

---

How to Add the Canonical Tag #

1. Open your Funnel → Select the Funnel Step.

2. Click Settings (top right).

3. Scroll to SEO Meta Data.

4. Locate Custom Head Tracking Code.

5. Paste this code:

6. Replace offers.example.com with your actual funnel subdomain.

7. Save and publish.

What This Solves #

• Removes redirect/mismatch warnings in Google Ads

• Prevents “final URL mismatch” rejections

• Ensures Google sees one stable version of the URL

• Avoids SEO duplicate-content issues

• Reduces indexing inconsistencies in search engines

---

When to Use This Fix #

Use this solution if:

• Your funnel is hosted on a subdomain

• Google Ads rejects the landing page

• You notice an extra funnel path (e.g., /summer-deal)

• You want the root URL to be recognized as the main landing page

• Google Search Console reports duplicate URLs

---

Important Notes #

• This does not change how your funnel behaves for visitors.

• It only informs Google/Google Ads which URL should be treated as the authoritative version.

• This is the recommended fix for funnels with multiple accessible URLs.
