If the phone number you insert into your Ads account is a tracking number or any other number you do not have listed on your website, then it's possible you may see a message like this in your Google Ads account:
The reason for this is that Google's robots have recognised that either the ownership of the domain hasn't been verified or there are phone numbers listed on the Ad but nothing on the website to match it.
Google provides two methods to verify your call extension phone numbers:
- Ensure the phone number used in the extension appears in text on the website featured in your ad.
- Prove that you own your domain by linking your Google Search Console to your Google Ads accounts. You can also add your unique Google Ads conversion tracking code snippet to the landing page featured in your ad if you prefer to verify ownership of your domain without using Google Search Console.
After linking your Google Ads and Google Search Console accounts, it may take several hours or days for the phone numbers to appear as verified.
When using Infinity, the recommendation is to verify a Google Search Console account to prove ownership of your ad's display URL.
