Criterion MA10: Create Lookalike Audiences — guide + checklist

Keyword : audience similaire facebook

This criterion (MA10) is used to **secure Facebook lookalike audience** and avoid errors that distort the audit or delivery.
In 2026, performance depends more on **Smart Bidding, conversion signals, and structural consistency** than isolated micro-optimizations.
**Score (impact): 7/10** — apply the checklist, then validate with an audit.

Why this criterion matters in 2026

  • Context: automation, privacy, and signal quality.
  • Objective: make the configuration **observable** and **stable**.
  • When it’s critical: whenever you change tools, templates, or structure.

Implementation checklist (step-by-step)

  • Confirm the objective (Sales/Leads) and signal quality (events, value, deduplication).
  • Verify Pixel + CAPI + consent, then test deduplication (event_id).
  • Limit changes: 1 variable at a time (budget, creative, targeting).
  • Monitor: Event Match Quality, cost per result, frequency, attribution.

Configuration / snippet ready to copy

  • **Meta — Pixel + CAPI (minimum viable)**:
  • Pixel active on all pages
  • CAPI: dedup via `event_id`
  • Events: `Lead` / `Purchase` + value if e-commerce
  • Check Event Match Quality in Events Manager

Validation & common errors

  • Optimizing on a bad signal (poorly defined conversion, inconsistent window).
  • Changing budget/bids too often (extended learning phase).
  • Over-segmentation (too low volume per entity).
  • **Validation**: check before/after (audit + manual test).
FAQ

Frequently asked questions — MA10

How to quickly verify Facebook lookalike audience?

Use the checklist above, then validate with an audit (tool) and manual verification on a sample.

How often should it be rechecked?

After any major change (theme, tag manager, campaign structure) and at least once per quarter.

What is the most common pitfall?

Confusing “configured” and “functional”. A setting may be present but inactive (conditions, consent, conflicts).
