Apple's iOS14 App Tracking Transparency update in 2021 caused 30–50% of Meta conversion events to go untracked for advertisers using browser-only Pixels. The Meta algorithm needs 50+ conversion events per week to optimize. If it's only seeing 60% of actual conversions, it optimizes for the wrong audience — directly damaging ROAS.
Server-side tracking sends conversion data directly from your server to Meta — bypassing iOS restrictions, ad blockers, and browser privacy settings entirely. Event match rates typically improve from 65–75% (browser only) to 95–99% (server-side). Most clients see 20–40% ROAS improvement from tracking alone.
