This case study demonstrates how the right combination of ad format and niche can drive meaningful results. By aligning strategy with execution, the use of the 300×250 banner format and targeted US traffic proved effective. Read on to see how this approach resulted in $1,675 in earnings and a 32% ROI in just a few weeks.
*The Cost-Per-Sale (CPS) model is a performance-based model when affiliates get paid only when a sale is made.
The campaign was launched using 300×250 banner ads. Pricing Model: CPC Initial Settings:
After 2-3 days of testing, the campaign gathered enough data to begin optimization. Based on the conversion data from the advertiser’s panel, a whitelist of zones was created. These zones had a registration cost that didn’t exceed the desired CPA by more than 50%, and the CPS stayed within the $20-28 range.
As the whitelist was further refined, only zones with registration costs between $1.8 and $4.1 remained. The higher the traffic volume on a zone, the more lenient we were with the registration cost. Some zones brought in up to 70% of the campaign’s traffic, with a Target CPA (CPS) between $24-28, but we decided to keep these in the whitelist as the average CPS across the whitelist stayed around $20.
In the first week, we also optimized the campaign by browsers. The best-performing browsers were:
These were the only browsers kept in the targeting after optimization. Additionally, we noticed that most conversions, including both registrations and sales, occurred between 16:00 and 04:00 EST, so we optimized the campaign schedule accordingly.
We used 5 dynamic GIF creatives in 300×250 format, featuring graphics and messaging around a free trial for first-time users. All 5 creatives showed relatively similar CTRs during testing. One advantage of the CPC model is that it allows for extended testing of creatives without losing budget, as the advertiser only pays for clicks, even if CTR isn’t particularly high.
The landing page featured a brief trial of the website interface, making users feel as if they had already signed up for a free trial. However, to receive the final AI-generated image, users had to register via social media or by entering their email and password.
By the end of the test period, the advertiser achieved a profitable CPS using Clickadu’s traffic and identified top-performing sources for potential growth. With the sources and data collected, the advertiser is well-positioned to scale this offer and launch similar campaigns without requiring an extensive testing phase.
