Easily Detect Destination Errors
in Meta Ads Automatically

After connecting via Facebook Login, click 'Sync' to import all ad accounts linked to your profile. Then, simply select the Ad Accounts you want to monitor (up to your Tier's limit). Our system will automatically scan all Active Ads in these Accounts every 24 hours to detect 404 Not Found and 503 Service Unavailable errors before they waste your budget.

Smart Filtering Logic

To avoid spamming you with errors from old/paused ads, our system only checks ads that are currently Active. This ensures we focus on where your money is actually being spent.

Deep Link Analysis

We don't just ping the URL. We analyze your ads at the Meta Graph API level. Our engine extracts the exact deep-link and validates the server response code to catch hard 404 and 503 errors with surgical precision.

Instant Alerts

If a broken link is found, we send you an immediate email notification with the exact Ad Name and Campaign so you can pause it instantly and save your budget.
