“Ad-Shield’s adblock revenue recovery solution was able to connect with various demand sources and quickly increased our revenue. Now, Ad-Shield is one of our most important partners and indispensable for our revenue generation.”


The problem: Lots of traffic, but low ad revenue

YGOSU is one of South Korea’s largest gaming communities, with over two million daily active users (DAU). The CEO approached us two years ago with a problem: Their ad revenue was significantly lower than their high traffic. They believed that the solution was to display more ads.

We advised against this. Though showing more ads can produce short-term results, simply increasing advertisements without considering UX creates negative ad experiences for users. As intrusive, annoying ads increase, the use of ad blockers grows. More ad blockers mean fewer impressions. Publishers end up showing more ads while lowering their eCPM and overall ad revenue.

We didn’t increase YGOSU’s ads. Instead, we first measured YGOSU's ad block ratio to determine the number of ad impressions that we could regain.

The cause: 40% ad block ratio (40% loss in ad revenue)

YGOSU assumed their ad-block ratio would be 5-10%. To YGOSU’s surprise, it was 40%, over four times their internal estimate.

Despite their sizeable traffic, YGOSU’s high blocked ads ratio was making them lose money. They realized a powerful ad tech solution was necessary to recover their substantial lost ad revenue. Being a gaming community, YGOSU had no experience with ad block recovery and was wary of wasting in-house engineering resources. Our team of dedicated adblock experts and guaranteed 90%+ recovery rate made Ad-Shield their vendor of choice.


Since 2021, Ad-Shield has

- Monetized over 700 million pageviews for YGOSU
