Five years after iOS14: what actually works for tracking now
Attribution never fully recovered after Apple's privacy changes, and it won't. But the gap between accounts that accepted that and accounts still waiting for the old world is now worth thousands a month.
Data & tracking lead
What actually broke
When Apple made tracking opt-in, browser pixels lost visibility on roughly a third of conversions overnight. The number got worse as browsers added their own restrictions. Most accounts still report fewer conversions than they generate, which means the algorithm optimises on incomplete data and everything downstream gets dumber.
The stack that works in 2026
Conversions API is the baseline now, not an upgrade. Events go straight from your server to Meta or Google, bypassing the browser entirely. Set up properly with deduplication, it recovers most of what the pixel misses. We install it on every account before touching campaigns.
First-party data is the second leg. Email lists, phone numbers, purchase records: upload them, match them, build audiences on data you own instead of data you rent. Customer Match on Google and custom audiences on Meta both run on it.
The third leg is boring discipline: consistent UTMs, a CRM that records lead source, and a weekly check that platform numbers roughly agree with reality. Not perfect agreement, rough agreement. Perfect doesn't exist anymore.
Setup checklist
- CAPI live and deduplicated
- GA4 events mapped to outcomes
- Customer lists uploaded monthly
- UTM conventions enforced
- CRM lead source mandatory
The mindset shift
The accounts that win now stopped asking 'which ad caused this sale' and started asking 'is the whole system profitable'. Platform-reported attribution was always flattering anyway. Blended maths, total spend versus total revenue, is uglier and truer.
If your tracking was set up before 2023 and never touched since, assume it's leaking. Our retargeting and funnel builds start with a tracking audit for exactly this reason, and the free audit covers it too.
If you skimmed
The short version
- Browser pixels miss up to 40% of conversions, CAPI recovers most of it
- First-party data (lists, CRM) is the targeting edge now
- Judge the blended numbers, not what each platform claims credit for
