How to write a good pattern.
The matching engine uses boundary-checked regex compiled from substring patterns. A good pattern is specific enough to avoid false positives, generic enough to match all current and reasonable future URLs of the vendor.
| Quality | Example | Why |
|---|---|---|
| Good | static.hotjar.com | Specific CDN host. No false positives. |
| Good | browser.sentry-cdn.com | Vendor-specific subdomain. Stable. |
| Risky | analytics.js | Many vendors use generic names. High false-positive risk. |
| Risky | cdn | Matches every CDN. Useless. |
| Bad | . | Matches everything. Will be rejected. |
Tips for high approval rates
- Use the vendor’s official CDN domain (e.g.
cdn.segment.com, notapi.segment.iounless that’s the script host) - Include 2–3 example URLs where you observed the vendor in the wild
- Pick the most specific category from the standard taxonomy
- If the vendor is vertical-specific, add a vertical tag (e.g.
v_ecommerce) - Skip fingerprinting and ad-serving vendors that don’t have a stable, public signature
