The Google Ads Ad Preview and Diagnosis tool, where you can preview your ads in the Google Search results, within the Google Ads interface is broken. It loads a CAPTCHA box and doesn’t let you remove the CAPTCHA from being displayed. So you cannot use the tool to preview your Google Ads.
The Ad preview and diagnosis tool helps you understand why your ad or ad asset might not be appearing and find a preview of how it appears on a Google search results page.
But again, it just doesn’t work. Here is a screenshot of the issue:
I spotted this via Govind Singh Panwar who wrote on X that this issue has been ongoing for about a week. He said that he “tried multiple devices and different internet connections, but I keep getting the reCAPTCHA “unusual traffic” page.” “It’s been more than a week,” he added.
It is not clear when this will be resolved.
Forum discussion at X.
