Ad link returns a 4xx error
The link from your ad ends on a page that returns 404, 410 or another client error.
Why it matters
Paid clicks land on an error page: the visit is wasted and platforms may disapprove the ad.
How to fix it
- Open the link from TagGap and follow it to the final URL.
- If a product or collection was renamed or deleted, add a URL redirect in Shopify admin → Content → Menus → URL redirects, or update the ad’s final URL.
- Re-run the check in TagGap to confirm the link resolves.
After a fix, TagGap confirms it on the next comparison run. Questions: support@taggap.com.
