Meta’s Engage-Through Window Is Toggleable — Most WooCommerce Stores Don’t Know
In March 2026, Meta redefined click-through attribution to include only link clicks — moving likes, saves, shares and video views into a new engage-through bucket with a fixed 1-day window. Reported click-through conversions dropped 15–40% overnight across WooCommerce stores. The engage-through window is toggleable (advertisers can turn it off or leave it at 1-day), but most stores haven’t adjusted it. For WooCommerce operators running CAPI, the fix is server-side event deduplication with proper event_id matching and optimising toward purchase signals within the tighter 24-hour engagement window.
