Pixel Hygiene · Audit
Pixel drift costs ROAS.
Why Pixel Drifts
Over months, new tools are added (Klaviyo, Yotpo, apps) that fire their own pixel events. Duplicate events appear. Naming conventions break. Custom events end up with wrong currency settings. EMQ drops gradually.

The Audit Checklist
- Pixel Helper browser extension on every page (PageView, AddToCart, Purchase)
- Identify duplicate events (same event firing twice per user)
- Check custom events for correct currency and value settings
- Ensure naming convention is consistent (verb_object_modifier)
- Server-side match rate in Events Manager (above 80%)
- EMQ score per event type in Events Manager
Example
Brands with an annual pixel audit keep EMQ stable above 8.0. Brands without one see EMQ drift to 6.5 within 12 months, often without noticing.
What to Do After the Audit
Deduplicate events (pixel or CAPI, not both). Enforce naming convention. Update currency settings. Set up an EMQ monitoring dashboard with an 8.0 threshold. Quarterly spot checks between annual audits.
