What is Event Match Quality (EMQ)?

Definition
Event Match Quality (EMQ) is a score from 0 to 10 that measures how well Meta can match a conversion event to a user, based on the customer parameters you send (hashed email, phone, name, external ID and more).
Also called: Event Match Quality, EMQ, Match Quality
Sådan virker det
Event Match Quality (EMQ) scorer fra 0-10, hvor godt Meta kan genkende brugeren bag en hændelse. Jo flere matchede parametre (hashet e-mail, telefon, ekstern ID), jo højere EMQ — og jo flere af dine reelle konverteringer kan algoritmen tilskrive og lære af.
01Why EMQ decides the payoff from your tracking
A server-side setup is only as good as the data it sends. The more matched parameters — hashed email, phone number, name, city, postcode, external ID (fbp/fbc), IP — the higher your EMQ, and the more of your real conversions Meta can attribute and learn from. An account that lifts EMQ from 4 to 8 sees measurably more conversions in-platform without anything changing in reality.
Better matching gives the algorithm a cleaner signal to optimise on, and that flows through to lower CPA and better scaling. EMQ is therefore one of the most concrete technical levers you have to lift performance without touching budget or creative.
Frequently asked questions
What's a good EMQ score?+
Aim for 7 or above out of 10. You get there by sending as many matched customer parameters as possible via the Conversions API — hashed email and phone carry the most weight, backed up by name, address and external IDs.
How do I raise my EMQ?+
Send more matched parameters server-side (hashed email, phone, name, postcode, external ID) and ensure correct deduplication against the pixel. Better data quality at the point of collection lifts the score directly.

What is server-side tracking?
Server-side tracking sends conversion events from your own server (e.g. via a server-side Google Tag Manager container and Meta's Conversions API) instead of from the user's browser — so data isn't lost to ad blockers, cookie restrictions and iOS limitations.

What is the Meta pixel?
The Meta pixel is a piece of JavaScript placed on your website that records visitor actions (page views, add-to-carts, purchases), so Meta can measure conversions and optimise ads.

What is attribution?
Attribution is the method that distributes the credit for a conversion across the touchpoints the customer met along the way. The model decides which channel gets the credit — and therefore where budget flows.
