AdBuyMCP vs Amazon DSP

We are built to buy through them. If Amazon audiences and CTV are the whole plan, go direct and skip the layer.

This comparison is awkward and the honest thing is to say why. Amazon DSP is one of the twenty-five connectors AdBuyMCP registers — a sub-seat covering connected TV and the audio pipe — and it is also a direct alternative to using AdBuyMCP at all. Both are true. Amazon's advantage is commerce data no third party can see and inventory across its own properties. Its access is not open: a sub-seat comes through an authorised reseller rather than a signup, which is a friction a small advertiser feels. If your plan is Amazon audiences against Amazon and streaming inventory, buying it directly costs less and starts sooner, and there is no honest argument for a layer between you and it.

What you get if you choose Amazon DSP

The case for the alternative comes first, in the terms it is usually made in rather than in ours. A comparison that opens by restating the alternative in our own vocabulary has already lost the reader who knows it better than we do.

Amazon's audiences and inventory, including Prime Video and the wider commerce ecosystem.

both columns

Where they are ahead, and what is actually left

Two lists at the same size, in the same card treatment, with theirs first. The left column is written without hedging and without a compensating clause on the end of each line, and the right one is often narrow — where the honest answer is three things rather than ten, it is three things long.

What is actually left

  • 01The five channels Amazon does not sell, planned against the same audience
  • 02One exposure record, so Amazon deduplicates against everything else rather than being counted separately
  • 03Seller-neutral allocation, including how much should go to Amazon at all
  • 04UK cinema and addressable television

4 against 4 on this page. The two columns are the same length here, which is how the material came out rather than a target: neither list is padded to match the other. Both lists are rendered from src/data/comparisons.ts unedited.

If the left column contains the thing your plan actually depends on, Amazon DSP is the better buy and a working session will say so in the first ten minutes.

Talk it through
// before you decide

Bring the brief, not the shortlist.

Forty-five minutes, a real audience, compiled live in the sandbox against the plan you are weighing Amazon DSP for. Where the honest answer is that Amazon DSP serves it better, that is the answer you get in the session rather than after a contract.

the decision

Which of the two you should actually buy

Both blocks are the same size, in the same box, with the same weight of rule around them. The one on the left is the case for not buying this, it is written to be actionable rather than to be dismissed, and on a page like this it is the more useful of the two.

Choose Amazon DSP when

Amazon audiences and inventory are the plan, and you can get a sub-seat. Adding a layer to reach one seller you can reach directly is a fee for nothing.

Choose AdBuyMCP when

Amazon is one leg of a UK plan and you want the split between it and five other channels argued rather than assumed — in which case Amazon DSP is one of the rails AdBuyMCP is built to buy through.

The verdict at the top of this page — “We are built to buy through them. If Amazon audiences and CTV are the whole plan, go direct and skip the layer.” — is the one-line version of both blocks, written before the argument rather than after it and published so it can be quoted back at us.

Neither block describes your situation exactly. A working session is where the actual version of the question gets answered, and the answer is sometimes the other one.

where to check this

The evidence behind both columns

Everything asserted above is checkable somewhere other than this page: in our own evidence ledger, in the published fee, or in the alternative's own words. The three are linked below rather than described.

The standing caveat

Of 25 registered connectors, 0 have spent money and 0 have reconciled a real report. Whatever is in the right-hand column above is a capability the sandbox demonstrates end to end and the live rails have not yet proved with a controlled paid activation, which is a real difference between this and every alternative on the comparison hub. The whole matrix, graded rail by rail with the blocker on each, is on the supply status page.

Every number above is checkable before you talk to us, which is the point of publishing them. The call is for the part that is specific to your plan.

The other alternatives on the same shortlist

Most buyers are weighing more than one of these at once, and the verdicts differ. Several of them recommend the alternative outright, which is worth knowing before you read them.

vs StackAdapt

They are the stronger DSP by a distance. The gap they leave is UK-specific paperwork and visible approximation.

5 ahead · 5 left

vs Universal Ads

For UK television alone, go direct. AdBuyMCP's argument only starts when a second channel is involved.

5 ahead · 4 left

vs Global AdPower

They own the inventory. If your audio and outdoor plan is a Global plan, buy it from Global.

4 ahead · 3 left

vs an agency

The fee comparison flatters us and the capability comparison does not. Both are true.

5 ahead · 5 left

vs Google and Meta

Not a replacement. An incremental layer around the budget you are already spending well.

4 ahead · 4 left

vs doing it yourself

For one or two channels, do it yourself. The case for a layer starts at three and gets stronger with each one.

4 ahead · 5 left

vs MNTN

They have the proven performance-CTV product. We publish what we charge. Decide which of those you need more.

5 ahead · 4 left

vs tvScientific

Their pricing model is better than ours for a qualifying performance buyer. That is not a concession, it is the honest answer.

4 ahead · 4 left

vs The Trade Desk

The category's most capable buying platform, priced accordingly. Not a fair fight on supply, and not the same job.

5 ahead · 4 left

vs DV360

Unmatched scale inside Google's ecosystem. The neutrality question is the whole point.

4 ahead · 4 left

vs Blis

Genuinely strong in the UK and on privacy, with a fee structure that beats ours. The gap is addressable TV, cinema and published fidelity.

4 ahead · 4 left

vs OOH specialists

Better out-of-home tooling than ours. Buy from them if out-of-home is the campaign.

4 ahead · 4 left

vs Basis

The same idea, built for agencies and for digital channels. The overlap is real and the gap is UK paperwork.

4 ahead · 4 left

vs Caasie

They proved the pattern. If you want DOOH with no minimum and no conversation, use them.
