"If I move to server-side, will my match rate go up?" The answer is yes — but not automatically by moving to the server. What decides it are the identifiers you send. Here's what actually raises match rate.
What match rate is
Match rate (Meta's Event Match Quality) says how well a platform can match your conversion to a specific user. Higher match rate = better attribution and a lower cost per result.
Why server-side helps
- More reliable delivery. Server-to-server sending gets through even where an ad-blocker blocks the client-side pixel — so there's something to match at all.
- A place to enrich. In the container you can add hashed identifiers from first-party data to the conversion before forwarding it.
What actually raises match rate
Moving to the server alone isn't enough — the key is quality hashed identifiers:
- Hashed email — carries the most weight; send it whenever you have one. The principle is in what hashing is.
- Phone, name, city/postcode — supplementary, where available and you have consent.
- Click IDs and cookies (fbc/fbp, gclid) — see what fbp and fbc are.
Summary
Server-side tracking improves match rate because it delivers the conversion more reliably and gives you a place to enrich it. But the real jump comes from quality hashed identifiers, not the move to the server itself. Send email and click IDs with consent and watch match rate rise. More in the Meta Conversions API guide.
