Third-party cookies are dead in Chrome since 2025. iOS continues to tighten ATT. Pixel-based tracking is mostly fiction in 2026. The local businesses who adapted are running on first-party data and a different definition of attribution.

What still works

  • First-party data: your own CRM, opt-in email and SMS list, loyalty program enrolments.
  • Server-side tracking: Conversions API, Enhanced Conversions, properly hashed identifiers.
  • In-store attribution: unique SMS code per campaign, redemption tied back to source.
  • Aggregated footfall: privacy-safe, anonymised mobile data via providers like Footfallcam, Adsquare.
  • Incremental testing: split your geography, run the campaign in half, measure the lift. The only true causal metric.

What to stop pretending to track

  • Cross-device journeys (without cookies, you're guessing).
  • View-through conversions: historically inflated, now mostly fictional.
  • Last-click attribution: gives credit to the last touch, ignores the brand campaign that did the heavy lifting.
  • Anonymous web visitors' behaviour: mostly noise without consent.

The privacy upside

The death of pixel tracking is, paradoxically, good for local. Local always lived more on real-world signals than on creepy attribution chains. The end of cookies forces every business to invest in first-party relationships: which is what local has always been about anyway.
