BIDLINE connects publisher inventory to hundreds of demand partners through live second-price auctions — no wasted impressions, no manual insertion orders, no guesswork on yield.
A publisher's ad slot signals an available impression — size, geo, device, and context data attached.
Connected demand partners evaluate the request in parallel and return a bid within the timeout window.
The highest bid wins at second-price clearing; the winning DSP is notified and billed for the win.
The winning creative is fetched and rendered into the slot — the whole cycle finishes under 50ms.
BIDLINE maintains direct auction pipes into demand-side platforms across display, video, native, and CTV — so inventory clears at the best available price without extra integration work on your side.
