Best Practices

Performance

Place script before closing </body> tag. The script loads asynchronously and doesn't block page rendering.

Testing

Test integration in staging environment before deploying to production. Verify script loads correctly.

API Key

Obtain your unique API key from the AntiBlocker dashboard. Never share your key publicly.

Monitoring

Track detection rates and user responses through the AntiBlocker analytics dashboard.
