Supply-Side Platform (SSP) — Definition & Explanation

Technology platform used by publishers to manage and sell their ad inventory programmatically. SSPs connect to multiple ad exchanges and DSPs, run auctions, enforce floor prices, and optimize yield. Publishers typically work with 5-8 SSPs.

How Supply-Side Platform (SSP) Works

An SSP receives ad requests from publisher pages via ad tags or header bidding, broadcasts bid requests to connected demand sources, runs auctions, enforces floor prices, selects winning bids, and delivers creatives — all in real-time.

Why Supply-Side Platform (SSP) Matters for Publishers

The SSP is the publisher's primary interface with programmatic demand. Choosing the right SSP partner is the single most important monetization decision a publisher makes. Stellor Media specializes in web publisher monetization with 50+ demand partners and 48-hour onboarding.
