View and fix issues by going to the Policy Manager. For each issue, you can do one of the following:
• Edit your ad to fix the issue. Saving your ads after editing them will automatically resubmit your ads for approval. As such, you do not need to submit your ads for review again manually.
• For ads with destination issues, first fix your ads’ destination page, then hover over the ad’s “Status” column and click the “Appeal” button to submit your ads for review.
We review most ads within 1 business day. Some reviews may take longer if an ad requires a more complex review.
If you have successfully fixed the policy issues, the ad’s status will change to “Eligible” after some time.
For others to assist you, you’ll need to provide more information about the placement of the ads, and how you have added them to your Ghost theme.
Whilst I am familiar with Google Ads, I don’t use them nowadays, and never have with Ghost. Nonetheless, you should pay attention to the policy violation: Restricted Verticals - Credit, Malicious software. Clearly there is something potentially malicious or untoward on your site, or linked from your site. I suggest you scan your site for vulnerabilities and malware–there are plenty of free resources online–and remove any infringing content or links. If you don’t think there is an issue you can appeal.
We did not place any ads on the server however used the Google Tag Manager to track ads to bring traffic to the site. The ads are Text ads created on Google Ads to drive traffic to the site. We tried with basic Ghost installation too creating a campaign and trying to drive traffic through a text ad. That too gave the same error.
Its nothing to do with placing any ads in Ghost. Its more outside in.
