AudioGoldCoin turns a standard HTML5 banner into a rewarded audio moment. A user taps, listens to a 15-second audio ad, and earns coins. No SDK, no app install, no new ad format to traffic.
Programmatic display traffic is plentiful and under-monetized. AudioGoldCoin layers an opt-in audio ad on top of it, served through the same banner slots you already run, and rewards the listener for their attention.
It ships as a self-contained HTML5 creative. If a slot can render a banner, it can run AudioGoldCoin.
Plays standard audio ads, including VAST tags, so existing audio buyers can reach display supply.
Listeners earn coins for completing a listen, a value exchange that lifts attention and recall.
Quartile and completion tracking out of the box, across desktop, mobile web, and in-app webviews.
Four steps, all inside the banner unit. The tap satisfies the browser's gesture requirement, so audio plays reliably across environments.
A standard display creative loads in the slot and invites the user to listen for a reward.
One tap starts a 15-second audio ad inside the banner. No redirect, no new app.
Completing the listen unlocks AudioGoldCoin, the proof that the value exchange landed.
A landing page lets the listener save their coins and opt in, building owned first-party data.
