A live install counter inside the description box
Influencer MarketingZorka.Agency added a live referral install counter beneath YouTube creator videos for Plarium, giving viewers a shared progress target and reporting doubled installs compared with standard integrations by the same creators.
About the campaign
Plarium needed a way to improve user acquisition as cost per install rose and reach plateaued. Zorka.Agency described the challenge as getting viewers to participate rather than simply watch a creator integration and move on. Its idea was to turn the install itself into a shared audience objective, with subscribers helping their favorite blogger complete a visible progress bar.
The agency built a custom widget and embedded it in the description beneath each participating YouTube creator's video. The bar displayed a live count of installs arriving through that creator's referral link. Viewers could refresh the widget to see the count rise and install to move the bar toward 100%. Creator videos supplied the audience relationship and the user acquisition integration, while the widget made the audience's collective progress visible alongside the content.
This structure connected a referral install to a concrete contribution for a preferred creator. Zorka.Agency reports that installs doubled compared with the same creators running standard integrations, alongside 1.5M+ views. Its metric panel records a 50% cost per install reduction, while the narrative describes a decline of more than 50%. The source also indicates a conversion rate increase without quantifying it. These are agency-reported results; the page does not disclose campaign dates, spend, absolute install totals or detailed comparison methodology.
