OpenRTB (oRTB) is the IAB's standard protocol for buying and selling ad impressions in real time. When a user loads a page, the supply side fires a bid request describing the impression — placement, GEO, device, OS, floor price — and demand partners answer with a bid and a creative inside roughly 100–300 milliseconds. Highest valid bid wins, ad serves, money moves. For performance buyers in dating, adult, and creator verticals, oRTB is how you get impression-level access to inventory that used to be sold only in opaque bundles.
The 60-second mechanics
Four pieces of the protocol actually matter to a buyer's P&L:
- Bid request — the impression's spec sheet. The fields you care about: site/zone ID, GEO, device, OS, browser, and ad format. This is what makes zone-level and device-level optimization possible programmatically — the same discipline we describe in our zone-level optimization guide, executed at machine speed.
- Bid floor — the minimum the supply side will accept. Floors on quality dating/adult inventory are real; bidding $0.10 under floor doesn't get you cheap traffic, it gets you zero traffic and wasted QPS.
- QPS (queries per second) — how many bid requests you can receive. More QPS is not automatically better: untargeted QPS means your bidder evaluates millions of impressions you'd never buy. Smart partners filter the stream to your GEOs and formats first.
- Win/loss + nurl/burl notifications — how you learn what you actually paid. Marry these to your tracker's conversion data and you have true impression-to-conversion economics.
What oRTB changes for performance advertisers
Three practical shifts:
1. Access without bundling. Traditional network buys sell you a blend — some great zones subsidized by filler. An oRTB pipe exposes each impression individually, so a sophisticated buyer can cherry-pick: only iOS in Norway, only members-area placements, only above-floor-by-X bids on zones that have converted before.
2. Speed of optimization. Manual zone optimization works on a daily review cycle. A bidder consuming oRTB data adjusts in real time. The catch: your conversion signal still arrives on human time (a dating SOI confirms in minutes; a deposit takes days), so the best setups combine programmatic bidding with human campaign rules.
3. Honest price discovery. Floors plus first-price auctions mean the clearing price reflects actual demand for that specific impression. You stop paying display-average prices for email-quality clicks — and stop getting email-quality prices on display-quality inventory.
When direct tags still win
oRTB is not a religion. Direct tags (or a managed insertion order on a known zone list) beat programmatic when:
- The inventory is curated and scarce — high-intent placements like members-area tabs don't need an auction to prove their value; they need a relationship that keeps you on them.
- You want predictable costs for a clean test. A $500–$2,000 validation test (the way our Sweden campaign started) is simpler on fixed CPC than on auction dynamics.
- Your team doesn't run bidder infrastructure. A DSP seat plus fees can eat the margin that made the traffic attractive.
The pattern we see among profitable buyers in 2026: direct buys on proven, high-intent zones; oRTB for scale and discovery.
How Vrume runs oRTB
Vrume is fully oRTB-ready on both sides of the marketplace:
- Publishers with 5,000+ daily impressions can integrate via a full oRTB endpoint or simple direct tags — display banners, email, push, interstitials, and in-app are all supported, with NET-15/NET-30 payouts. Details on the publisher page.
- Advertisers can buy the same inventory as managed CPC/CPM campaigns — prepaid, no auction complexity — while our team handles the zone-level optimization weekly. Programmatic buyers who want a direct pipe can talk to us about endpoint access.
Either way you get the part of oRTB that actually matters — impression-level transparency — without being forced to build bidder infrastructure to use it.
Key takeaways
- oRTB is impression-level market access: bid request in, bid + creative out, ~100–300ms round trip.
- Floors and QPS discipline determine your real costs more than your max bid does.
- Direct tags still win on curated, high-intent inventory and clean small-budget tests; oRTB wins on scale and discovery. Run both.
- Vrume supports both models: managed prepaid CPC/CPM campaigns, or oRTB integration for publishers and programmatic partners.
