At TrafficStars, advertisers choose the CPM (Cost Per Mille) model to pay for impressions – giving them full control over costs and room to optimize for conversions. In our previous case study on a Nutra offer in India, we explores how CPA can drive results in cost-efficient regions. Now, we’re taking things to the next level.
This new campaign promoted an AI tool in top English-speaking markets, with a clear performance goal: achieve an eCPA under $1.5. The campaign combined banners and popunders, PRIME traffic, and a smart optimization strategy.
