Check Your Revenue Potential →What is a Programmatic SSP?
A programmatic Supply-Side Platform (SSP) is the technology infrastructure that allows web publishers to sell their digital advertising inventory through automated real-time auctions. When a visitor loads a page on a publisher's site, the SSP broadcasts a bid request to connected demand partners — DSPs, ad exchanges, and direct buyers — collects bids in under 300 milliseconds, runs an auction to select the winning bid, and delivers the winning creative to the user's browser.
The programmatic SSP sits at the core of modern publisher monetization. Without an SSP, publishers would need direct relationships with every advertiser — an impossible operational burden at scale. With a well-connected SSP like Stellor Media, a single integration unlocks access to thousands of advertisers and billions of dollars in demand, with pricing optimized automatically for every impression based on real-time market signals.
The quality of the SSP relationship directly determines publisher revenue outcomes. SSPs that connect to more demand partners, implement better floor pricing algorithms, and provide dedicated publisher support consistently outperform generic exchanges by 30-60% on equivalent inventory.
How Stellor Media's SSP Works
Stellor Media's programmatic SSP is built on three technical pillars that drive publisher revenue:
- Header Bidding via Prebid.js: Our Prebid.js adapter runs competitive auctions across all 50+ demand partners simultaneously, ensuring every impression goes to the highest bidder rather than the highest-priority partner in a waterfall.
- OpenRTB Integration: Full OpenRTB 2.5+ compliance enables connection to every major DSP and trading desk, with structured bid request enrichment that helps buyers make confident, high-value decisions.
- Dynamic Floor Pricing: Our proprietary floor algorithms analyze hundreds of real-time signals — geography, device, content category, time of day, bid density — to set optimal floors that maximize revenue without sacrificing fill rate.
Additionally, Stellor Media's Google MCM partnership enables publishers to access Google demand through our managed network, adding the world's largest demand source to the competitive auction without a separate Google relationship.
