CTV SSP Fees and Take Rates: How to Compare Supply Partners
How SSP fees and take rates work in CTV and online video, how to compare supply partners on working media, and what to ask for in contracts.
The short answer
An SSP take rate is the share of the buyer's media cost the SSP keeps before paying the publisher. In CTV and online video, the total cost between buyer and publisher also includes DSP fees and any reseller margins. Buyers compare supply partners by asking for fee disclosures, using log-level data to see clearing prices, checking the number of intermediaries, and measuring the share of spend that reaches the publisher on verified, viewable impressions.
Every party between your DSP and the streaming publisher takes a cut. In CTV, there can be more parties than in display: an SSP, a reseller, a syndication partner, and a platform revenue share. The take rate question is really a question about how much of your money buys media.
Where the money goes
A simplified path:
- Advertiser pays agency and DSP.
- DSP takes its fee and bids.
- SSP runs the auction and takes its fee.
- Any resellers take a margin.
- Publisher (or platform) receives the rest.
Industry studies, such as the ANA's programmatic transparency work, have found that a meaningful share of spend does not reach publishers. The exact figure varies by path, so measure your own.
Why fair rates are hard to state
- Contracts differ by deal type: open auction, PMP, programmatic guaranteed.
- Some SSPs charge buyers, some sellers, some both.
- Bundled services (curation, data, ad serving) blur the line.
Rather than chase one number, compare like with like.
How to compare supply partners
| Check | How |
|---|---|
| Fee disclosure | Ask each SSP and reseller to state its fee on your deals in writing |
| Clearing prices | Use log-level data to compare what you paid with what publishers report |
| Hops | Use the SupplyChain object to count intermediaries |
| Authorization | Check app-ads.txt and sellers.json |
| Quality | Compare viewability, completion, and IVT by path |
Then calculate cost per verified, completed impression on each path. A path with a higher fee and much better quality can still be cheaper per useful impression.
Questions for a CTV supply partner
- What is your fee on our deals, and who pays it?
- Are you a direct seller or reseller for each publisher in the deal?
- How many hops do typical impressions take?
- Will you provide log-level data?
- Do you offer curated deals, and what do they add in fees?
Reducing fees
- Consolidate paths. Fewer SSPs per publisher. See supply path optimization for pharma.
- Direct paths. Prefer sellers listed as DIRECT in app-ads.txt.
- Programmatic guaranteed with major publishers.
- Quality-weighted choice. See quality path optimization.
Common mistakes
- Comparing SSPs on CPM alone.
- Ignoring reseller layers in CTV.
- Assuming curated deals are always more efficient.
- Not asking for fees in writing.
Practical takeaway
For your top five CTV publishers by spend, list every path you buy them through and the fees each path discloses. Moving spend to the best-documented, lowest-hop path is the simplest fee cut available.
Frequently asked questions
What is a fair SSP take rate?
It varies by deal type and service level, and contracts are often confidential. Rather than a single benchmark, compare partners on the share of your spend that reaches publishers for comparable inventory.
Can buyers see SSP fees?
Not always directly. Some SSPs disclose fees on request or in curated deals; log-level data and supply chain audits can help estimate them.
Do CTV supply paths have more intermediaries?
They can. Resellers, syndication partners, and platform revenue shares can add layers between buyer and content owner.

I work on health and pharma data, identity, and activation, after five years running HCP and DTC programmatic agency-side. Happy to talk through how this applies to your situation.
