We took 40 of our largest e-tailers with a variety of products that have spent more than 43 million in ads over the past 12 months and compared their results in Tanganica with results from their own campaigns.

To simplify the calculations and make the results more relevant, we only compared investment in Google advertising. Unfortunately, the data from the e-commerce campaigns also includes data from brand campaigns, which we do not have in Tanganica and which slightly affect the results.
