Meta’s LPA Rollout Just Split Your EU Audience Into Two Tiers
In January 2026, Meta rolled out non-dismissible Less Personalized Ads (LPA) choice flows to every EEA user, the third revision after the European Commission’s €200 million DMA fine. Meta’s own filings acknowledge the option uses approximately 90% less data than personalized ads. A measurable segment of EU users has now selected it, splitting Meta’s EU ad delivery into two training sets — one detailed, one ~90% sparser. WooCommerce campaigns are now being optimized against the blended average. Ads Manager doesn’t show what proportion of your EU audience is on which tier. Your CAPI-sourced server-side events become the bidding model’s proportionally most reliable EU input.
