67% decrease in cost per acquisition after phone attribution.

A national mobile service provider operating 50+ vans across 3,500 suburbs used Gibson call tracking through a Webhook API and Google Analytics to connect phone demand with campaign reporting. The verified campaign results were a 67% decrease in cost per acquisition, 60% more offline conversions, a 33% conversion-rate uplift and a 36% reduction in spend, saving tens of thousands of dollars per month.

Evidence reviewed

Evidence dossier

What the published record establishes.

Evidence reviewed 2 August 2026
Status

Governed anonymised client record. The four published campaign metrics are supported by that record. The client identity, raw report and comparison query are not published.

Operating context

National mobile service provider with more than 50 vans operating across about 3,500 suburbs.

Baseline

More than half of sales closed by phone or live chat and were not represented in the digital campaign view.

Intervention

Call Tracking connected phone demand to campaign reporting through a Webhook API and Google Analytics.

Timeframe

The measurement window and implementation dates are not recorded in the publishable case summary.

Evidence

Governed campaign record supporting the published before-and-after marketing measures.

Outcome

67% lower CPA, 60% more offline conversions attributed, 33% higher conversion rate and 36% lower spend in the recorded comparison.

Comparable when

Operators with material phone or live-chat sales that are missing from the campaign and acquisition-cost view used for budget decisions.

Not established by this case

That Call Tracking alone caused every change, that the same percentages will repeat, the result outside the recorded comparison, or a standard implementation price or timeframe.

The problem

A national mobile service provider had clear data on digital bookings and online sales. But over 50% of their sales closed over the phone or via live chat. Those conversions were invisible. Marketing had accurate data on half the picture, which meant budget decisions were based on guesswork.
