A practical guide to running Meta Ads in 2026 — Conversions API, EMQ tuning, dedup, and why measurement discipline now beats creative volume.
Why this post exists
Every month I take an inbound call from a brand whose Meta Ads have “stopped working.” Nine times out of ten, the ads haven’t stopped working — the measurement has. Pixel-only setups, broken dedup, unmonitored EMQ. The CPMs are fine; the data is wrong.
The four things to fix this week
- Conversions API. If you don’t have CAPI, install it. Not “later.” This week. Server-side or via a managed integration — both work; the wrong answer is none.
- Deduplication. Make sure Pixel + CAPI events are sending the same event ID. Without dedup, Meta double-counts and you get false confidence.
- EMQ score. Push every standard event above 8.0. Send hashed PII (email, phone, name, city, zip) with every purchase or lead event.
- Custom event for high-quality conversion. Don’t optimise for “Lead.” Optimise for something like “Lead_Confirmed_By_Sales” — a higher-quality custom event that closes the loop.
What you get
The accounts I’ve migrated through this sequence have all shown the same pattern: a 3–8% lift in attributed conversions (because dedup stops the double-count), a 10–15% lift in algorithmic targeting quality (because EMQ is finally good), and a clean baseline from which to actually evaluate creative. You stop fighting the platform and start running media against real signal.
