Co-op or Coop

Amazon & D2C glossary · Harpy Media

Co-op (cooperative marketing, sometimes “automated marketing” in Amazon’s vendor systems) is the 1P practice of Amazon promoting a vendor’s products — display placements, category features, campaign inclusion — with the cost deducted from the vendor’s payments. You fund the promotion; Amazon executes it; the invoice settles it.

What is Co-op or Coop?

Co-op (cooperative marketing, sometimes “automated marketing” in Amazon’s vendor systems) is the 1P practice of Amazon promoting a vendor’s products — display placements, category features, campaign inclusion — with the cost deducted from the vendor’s payments. You fund the promotion; Amazon executes it; the invoice settles it.

It’s the vendor-world cousin of buying ads, with one big difference: co-op runs through negotiated percentage terms and automated deductions rather than a self-serve console with clear auction prices. That opacity is the challenge — and the reason disciplined co-op management looks more like finance than like media buying.

Where co-op money goes

Common formats: on-site display units featuring the brand, category landing-page inclusion, seasonal campaign participation (holiday gift guides, event pages), email placements, and enhanced content programs. The mechanics run through vendor agreements — rates set at AVN, deductions automated against invoices. The recurring problem is attribution: placements report loosely (“impressions” without sales context), so vendors struggle to answer the only question that matters — what did each funded dollar return?

Making co-op accountable

The playbook disciplined vendors run: itemize everything (demand placement-level detail in the agreement or through your vendor manager), measure what’s measurable (funded ASIN velocity during placement windows versus baseline — imperfect but honest), and separate performance funding from unitemized percentages (fund the former aggressively; challenge the latter annually). Pair co-op with the self-serve levers vendors also have — Amazon Ads consoles, deals — and compare cost-per-incremental-sale across both before renewing anything.

In practice

A vendor funds a gift-guide inclusion through co-op and — for the first time — measures it: funded ASINs run +41% velocity in the placement window against their trailing baseline, with a halo week after. The same season’s unitemized $45k shows nothing traceable. Next AVN: the gift-guide line doubles, the unitemized block is cut in half. The vendor didn’t spend less; they spent on evidence.

How Harpy Media helps

We hold vendor marketing funding to the same accountability as auction ads — measured windows, honest baselines, evidence at renewal.

Co-op or Coop FAQ

What is co-op in the Amazon context?

Vendor-funded marketing executed by Amazon — placements and campaigns paid via negotiated deductions from vendor payments.

Who pays for co-op marketing?

The 1P vendor — through percentage-based deductions agreed in annual negotiations.

How do I know if co-op is working?

Measure funded ASIN velocity during placement windows against baseline — and itemize every placement so there’s something to measure.
