Case study · Luxury and high-consideration retail

How a fine jewellery brand recovered 100%+ of its conversion revenue data.

Google Tag Gateway under Google funding.

100%+

Recovered revenue data inside 30 days

The challenge

What wasn’t working

A high-end fine jewellery brand was losing more than half of its conversion signal to ad blockers and ITP, despite running a Google-funded ad stack at scale. The paid team could see the spend going out and the customers walking in, but couldn’t connect the two.

The board wanted a finance-grade view of marketing contribution. The setup as it stood could not deliver one. Without a credible answer, the next budget conversation was going to be a difficult one.

What we did

How we delivered it

01 Eligibility check and submission

Confirmed eligibility for Google Tag Gateway funding and submitted on the brand’s behalf in the same week.

02 Consent layer audit

Reviewed the CMP rollout, fixed misfires, restored consented-audience tracking properly.

03 Google Tag Gateway deployment

Implemented GTG on the brand’s own domain. Ad-blocker losses removed from priority conversions.

04 Conversion modelling validation

Compared restored conversion volumes against the pre-implementation baseline for two consecutive months.

05 Offline conversion pipeline

Wired bespoke high-touch sales paths (including in-person consultations) back into Google Ads as offline conversions.

06 Finance-grade revenue dashboard

Stood up a Looker Studio dashboard reconciling Google, Meta and the brand’s booking system.
