Brief Overview of the Publisher Story
For today’s case study we have selected a publisher who started solo, just experimenting with simple tools and ideas.
Instead of spending a lot of money upfront, they built a basic converter using open-source software and a free hosting option.
- Backend: Python (Flask)
- Database: MongoDB
- Audio processing: LAME MP3 encoder / FFmpeg
- Hosting: free cloud solutions (like Streamlit Cloud or similar)
The whole project focuses on a simple but popular need: an online YouTube-to-MP3 converter that lets users quickly turn videos into audio, like music concerts, podcasts, you name it. Most of the traffic is organic and search-driven, so users show up with a clear goal and act quickly. That means you get a steady flow of new visitors, which keeps ad fatigue low and engagement high.

What Traffic Strategy is Used?
The publisher also spreads out their efforts by running several converter tools, in this article we will show the statistics of three websites. Each site targets different keywords, regions, and types of traffic.
If you look at the SimilarWeb data, you’ll see traffic is spread out across the sites:
- Some websites attract near a million of visits monthly
- Others remain relatively small with niche or experimental traffic
This is exactly why the strategy works so well:
Instead of relying on one main site, the publisher builds and grows a network of websites. Each one adds to the total revenue. Even smaller sites help by testing new ideas, capturing niche traffic, and supporting growth.
Relying on only one monetization partner is risky. This publisher understands that and avoids it. work with several ad networks at the same time including HilltopAds to:
- Compare performance across different traffic segments
- Maximize fill rates and overall revenue
- Reduce dependency on any single source

Utility websites are one of the best matches for Popunder ads because users come for a quick action and leave. If you monetize that exact moment without interrupting the process, you get both: good UX and strong revenue.

Placement Strategy: Monetize the Right Moments
Rather than placing ads at random, the publisher chooses to show ads during key user actions, when engagement is highest. Actions such as clicking “Convert” or “Download” show clear intent, so these are the best times to trigger ads.
Why does this work so well?
- Seamless integration into the user journey
- No disruption to the core product experience
- High interaction rates → higher earnings
This model is effective because it captures value right when it counts most.
It brings together high-intent traffic, action-based triggers, and mobile-friendly formats to reach users when they are most engaged and ready to take action.
This approach creates a smooth experience for users and consistently brings in higher revenue. Over time, setups that are cleaner and better matched to users usually do better than aggressive methods, leading to more stable and scalable results.

Don’t trigger Popunders on every single click. Over-triggering can hurt long-term performance. The best results usually come from controlled frequency, for example, once per session or tied to meaningful actions like ‘Convert’ or ‘Download’. That way, ads show up right when users are most engaged.
Results: $168,834 in Revenue
Since launching monetization in Spring 2024, the publisher has generated $168,834.01 in total revenue.
Interestingly, growth did not come from one big breakthrough, but from building multiple projects and gradually learning how to monetize a website more effectively over time.
