THE CHALLENGE

Prove the true incremental impact of Self’s marketing efforts — particularly on social media platforms like TikTok.

Determine whether their TikTok campaigns (web+mobile) were actually driving conversions — and how these campaigns compared to their overall CAC benchmarks.

With standard tracking and attribution falling short, the Self team lacked the data needed to confidently scale or optimize their TikTok efforts for ROI. ​
THE APPROACH

Self & TikTok turned to Twigeo for help.

We quickly identified that our GeoLift solution* was ideally suited to measure the true impact of their TikTok investment through geo-based experimentation.

HOW IT WORKS

Using our proprietary AI & machine learning algorithms, we split a market into:

Control (no changes)

and Treatment (turn media off/launch new media).

After analyzing Self’s historical conversion data, we designed a holdout test using synthetic control methodology. 60% of TikTok campaigns were paused and 40% had BAU + spend from Treatment.

THE RESULT

Conversions dropped by 6%*, with 99% statistical significance


This revealed that the TikTok campaigns:
Drove more conversions than reported in TikTok’s native interface

Outperformed internal expectations
delivered a lower CAC than many other channels

*This drop was identified by comparing the actual number of conversions to a synthetic counterfactual, which reliably shows what would have happened had the campaigns continued as usual.

Armed with these insights, Self was able to:

  • Confidently increase their TikTok investment.

  • Improved blended ROI.
  • Unlock a new growth opportunity.

The results not only exceeded expectations — they also equipped Self with a scalable experimentation framework for future decisions.

Traditional attribution falls short in a privacy-first world.

GeoLift provides a privacy-safe, platform-agnostic way to measure true incremental impact with greater clarity.
