Starting point

A Hungarian–German B2B webshop on two domains, with two separate Google Ads accounts. Part of the revenue comes from webshop purchases, but the larger deals come from quote requests, phone calls and email. Ads ran in both markets, but the accounts couldn't see clearly what happened after the click.

What the audit found

  • A conflicting tracking pluginThe webshop plugin sent events in parallel with Tag Manager, so purchases didn't arrive once.
  • Missing cookie handlingThe tracking tags ran regardless of consent, and Consent Mode v2 wasn't set up.
  • Untracked inquiriesPhone and email inquiries never reached Google.
  • Enhanced conversionsGoogle Ads showed enhanced conversions warnings in both accounts.

What I built

  • A Tag Manager container for both domains, with shared logic
  • A purchase event with transaction ID, value and currency, sent to the right Google Ads account
  • Enhanced conversions for purchases and quote requests
  • Tracking of phone and email inquiries
  • A cookie banner with Consent Mode v2, connected to the tracking tags
  • Removal of the conflicting plugin, verified with real test orders, documented

iOS app of an AI-powered job portal

Complete measurement plan, Firebase and Meta SDK events, ATT and SKAdNetwork, built together with the development team.

The app had no measurement specialist. I wrote the event map and the implementation guide, the developers connected the SDKs from it, and I verified that the events reach Google Ads and Meta accurately.

Let's see what's going on with your tracking.
