Pixel & CAPI Diagnostics
Check what tracking is installed on any URL: Meta Pixel, GA4, GTM, TikTok, Google Ads.
Enter your Pixel ID. Tool checks event match quality, deduplication between browser pixel and CAPI, missing events, broken parameters, and ATT-impacted iOS attribution. Get specific code fixes for each issue.
Why this exists
Most pixel issues are silent — they don't show errors, just lose conversion signal. Post-iOS 14, a misconfigured pixel can cost 30-50% of reported conversions, which Meta's bidder uses to optimize delivery.
Use cases
- Audit a new account before scaling spend
- Diagnose why CPA inflated suddenly with no other changes
- Verify CAPI is actually capturing events (not just installed)
- Check match quality against industry benchmarks
FAQ
Do I need to grant access?
Read-only Pixel API access via Business Manager. No ability to modify your account.
What's a healthy match quality?
6.5+ on Meta's scale (out of 10). Below 5 means most events aren't connecting to real users.
Does it check Google/TikTok pixels?
Currently Meta only. Google Tag and TikTok Pixel support planned.
