The bottom line
iOS 14.5 changed Meta advertising fundamentally. App Tracking Transparency reduced the conversion signal available to Meta's algorithm, attribution windows shortened, and reported ROAS dropped 30-50% across most accounts as conversions stopped being properly tracked. The brands that responded by configuring Conversions API, adopting modelled conversions, and adapting creative strategy continued to scale profitably. The brands that didn't are now running accounts where Meta reports a 0.8x ROAS while the actual blended ROAS (measured properly through GA4, Triple Whale, or similar) is 3-4x — they pulled budget unnecessarily because the reported numbers looked worse than reality. in Wolverhampton The second shift is the creative-first algorithm. Audience targeting on Meta has been progressively commoditised — broad targeting often outperforms detailed targeting because Meta's ML has more signal to optimise against. The differentiator is now creative quality and variety. Brands running 5-10 fresh ad creatives per week scale; brands running the same three videos for six months see CPM creep, CTR drop, and CPA inflate. Creative production needs to be a continuous operational process, not an occasional refresh. JW Digital handles both shifts properly. Conversions API set up correctly with deduplication, modelled conversions enabled, and attribution measured against blended sources rather than just Meta's reported numbers. Creative testing as a systematic process — UGC sourcing, founder content production, demonstration videos, hooks tested against benchmark CTRs. Pairs naturally with our content marketing strategy, social media management, and conversion rate optimisation services for full-funnel ownership.
