The challenge

Why rethink programmatic buying?

A single campaign can involve low-quality inventory, cluttered placements, complex supply paths and heavy cookie dependence. The Master Deal addresses these challenges together, rather than one at a time.

01

Inconsistent quality

Long-tail inventory, ad-cluttered sites and small placements can reduce the actual impact of creatives.

02

Fragmented audiences

Cookie-only strategies can miss valuable opportunities for incremental reach.

03

Complexity and opacity

Too many settings, intermediaries and hard-to-understand fees.

Four pillars

How does the GreyFox Ads Master Deal work?

Curation happens upstream of the media buy, with a single Deal ID activated directly from your DSP.

01 · Supply

Curate premium supply

  • Prioritize a curated selection of approximately 700 French websites to avoid the long tail.
  • Exclude ad-cluttered websites and subdomains.
  • Optimize viewability and the share of screen occupied by ads (screenshare).
  • Supply Path Optimization (SPO): favor direct publisher routes and resellers that add measurable value.
02 · Audience

Deploy smarter targeting

  • Go beyond cookie-only targeting.
  • Combine contextual signals, panels, available identifiers and cookies as appropriate.
  • Prioritize incremental data value and avoid unnecessary data fees.
  • Extend reach across cookieless environments.
03 · Trading

Simplify activation

  • One Deal ID for the media trader.
  • Curation settings are managed upstream through the GreyFox Ads curator seat.
  • Potential activation through DSPs such as DV360, The Trade Desk, Amazon DSP, Adform or Hawk, subject to compatibility and setup.
  • Fewer line items and manual steps for the buying team.
04 · Finance

Make costs transparent

  • Provide a breakdown of the different cost components.
  • Show the value delivered by services and intermediaries.
  • Apply data fees only where incremental value justifies them.
  • Make buying decisions easier to explain and document.
The principle: concentrate optimization in the curation layer while keeping activation straightforward for trading teams.
