Link health checks
Find marketplace links that have stopped working.
What the checker does
Once a week the plugin checks your saved marketplace URLs in the background, in batches, and flags the ones that are clearly broken. A dead listing sends shoppers to an error page, and without a check nobody notices until a customer says so.
Only definite failures are flagged: a 404, a 410, or a domain that no longer resolves. Timeouts, redirects and rate limiting are left alone, because marketplaces routinely produce those for automated requests and treating them as failures would fill the report with noise.
Seeing the results
Flagged products show a warning icon in the Marketplaces column on the Products list. EM Buttons → Advanced has a Link Health section listing every problem URL with the product it belongs to.
Checking on demand
The same section has a Check Now button that runs a batch immediately rather than waiting for the weekly schedule. Fix a URL on the product, run the check again, and the flag clears.
