Inventory and targeting in DV360: audiences, formats and real reach
Published August 19, 2026
A DSP is worth exactly two things: who it lets you reach and where. This is the practical tour of both sides in DV360 — the audience toolbox and the inventory footprint.

Let's talk →The audience toolbox
| Type | What it is | When to use it |
|---|---|---|
| Google audiences | Intent, in-market, affinity and demographic segments built from Google signals | Prospecting at scale — and at no extra data cost in DV360 |
| First-party | Your CRM lists, site visitors, app users | Retargeting, exclusions, lookalike seeds |
| Third-party | Purchasable segments from data providers | Niche B2B or category targeting your data can't cover |
| Contextual | Page content, keywords, categories | Cookieless-proof relevance; strong for brand campaigns |
| Geo + tech | Location, device, OS, connection | Structural filters layered on everything above |
Two notes that matter in practice. First: Google's audience segments are included — in most DSPs, third-party data of that quality carries a CPM surcharge. Second: contextual has come back hard as cookies fade; combining context with first-party data is today's most durable targeting stack.
The inventory footprint
DV360 buys across 80+ exchanges plus Google's own supply:
- Display: the classic — millions of sites, all screen sizes.
- Video & YouTube: online video across the open web plus YouTube bought with DSP-grade controls.
- Connected TV: streaming apps and smart TV inventory, the fastest-growing branch.
- Audio: music and podcast streaming.
- DOOH: digital billboards and venue screens, bought like any other line item.
- Mobile in-app: exchange inventory beyond what app networks sell.
Quality control is built in: site lists, category exclusions, viewability thresholds and — where open auction isn't enough — deals with specific publishers.
Layering is the craft
None of these tools works alone. A working line item stacks them: in-market audience × contextually relevant placements × viewability floor × cross-channel frequency cap. That layering — matched to each campaign objective — is where operations differentiate, and it's the skill you either build in-house (Self) or borrow (Manage).
If you're still weighing whether this power is worth a second platform, start with DV360 vs Google Ads.
