Demand-Side Platform (DSP)

A DSPGlossaryAd NetworkA platform that aggregates ad demand from many advertisers and matches it to publisher inventory through real-time auctions. (demand-side platform) is the advertiser-side interface to programmatic advertisingGlossaryProgrammatic AdvertisingThe automated buying and selling of digital ad inventory through real-time auctions, replacing direct deal-making between advertisers and publishers.. Advertisers use DSPs to: set audience targeting rules, upload creatives, configure bid strategies, allocate budgets, and report on performance — all across multiple ad exchanges and inventory sources simultaneously. The DSP handles the technical complexity of programmatic (RTBGlossaryReal-Time Bidding (RTB)The auction protocol underlying programmatic advertising — each ad impression auctioned in 50-150 milliseconds via the OpenRTB specification. integration, audience data activationGlossaryActivationThe percentage of installs who complete a defined "activation event" — the action that converts a passive install into an active user., bid optimization) so advertisers can focus on strategy.

DSP vs SAN — what each does best

• DSPs: cross-channel reach (mobile + CTV + display), in-app inventory at lower CPMGlossaryCost Per Mille (CPM)The price an advertiser pays for 1,000 ad impressions, regardless of whether those impressions drive clicks or installs. "Mille" = Latin for 1,000. than direct SAN buying, custom-audience activation (your CRM data → bidding signal), brand campaigns where reach matters more than performance attribution.

For mobile-app advertisers, the practical split is usually 70-90% SAN + 10-30% DSP. DSPs add incremental reach beyond what SANs deliver; they don't replace SAN scale.

Mobile-app fit considerations

SANs handle it natively. Setup is heavier.
• In-app inventory access: most DSPs integrate with major mobile ad exchanges (PubMatic, Magnite, OpenX, MoPub formerly). Verify their mobile inventory depth for your category.
• Audience activation: DSPs work best when you have first-party audience data (CRM, web visitors, app users) to upload as bid-targeting seeds.
• Reporting integration: most DSPs integrate with major MMPs for unified attribution reporting.
