Monetize every impression your current stack doesn't fill
If you're running direct deals or header bidding, you already know some percentage of your inventory goes unsold or fills at a discount. AdBunny catches that gap.
Get Your JS TagThe remnant inventory problem
Even well-optimized ad stacks leave impressions on the table — geos with thin demand, times of day with low bid density, slots outside your top placements. Traditionally, publishers deal with this using a fixed waterfall: call network A, then B, then C, in a set order, regardless of what's actually the best-paying option for that specific impression. It's simple, but it leaves revenue behind.
How AdBunny fills the gap
Sits below your primary stack
AdBunny is a backfill layer, not a replacement. It only evaluates inventory your existing direct deals and header bidding partners didn't fill.
AI picks the best banner per impression
Instead of a static call order, AdBunny's optimization layer evaluates real-time demand for each individual impression and serves whichever banner is likely to pay the most.
One tag, no dev lift
No line items to configure, no waterfall to maintain, no new SDK for your engineering team to integrate. Paste the tag, done.
What you get
Higher fill rate on remnant slots
AI-driven yield optimization instead of a static, out-of-date waterfall.
Zero interference with primary demand
No conflict with your existing direct-sold or header-bidding demand.
Same-day setup
One tag, no ad-ops overhead, no engineering sprint required.
Who this is for
Publishers and app developers of any size dealing with unsold or underperforming banner inventory — from independent sites supplementing a small ad stack to larger publishers looking to squeeze more yield out of remnant slots without adding ad-ops overhead.
