In performance marketing, the right bidding strategy can make or break your campaign. At TrafficStars, most advertisers use the CPM (Cost Per Mille) model — paying for impressions while keeping full control over costs and optimization.
In our previous case study, we explored how Nutra campaigns achieve profitability in emerging GEOs. This time, we’re going global — testing an AI offer in top English-speaking markets with a clear target: an eCPA under $1.5.

How to Boost Ads Effectively in Ad Networks
Whether you’re promoting AI tools, gaming apps, or subscription offers, these principles apply to every campaign:
- Start broad, test fast.
- Use CPM to find what converts before scaling with CPA.
- Use data, not guesswork. Let postback tracking and eCPA guide decisions.
- Combine formats. Mix banners for profitability and popunders for reach. Leverage PRIME traffic.
- Compete on top-quality spots to ensure conversions. Analyze constantly.
- Bid adjustments and optimizer tools help fine-tune ROI.
This is exactly how to optimize bids for better performance — by iterating fast and scaling what works.
Conclusion
CPA is a powerful pricing model – when executed with the right strategy.
In this case study, we explored a campaign promoting a niche AI product in English-speaking markets. The approach was clear and effective: begin with CPM testing to gather data, optimize with a CPA bid, and then scale once the model proves profitable.
The results speak for themselves – success comes from getting the fundamentals right.
