The GreyFox Ads Master Deal
One Deal ID. More efficient, simpler and more transparent programmatic buying.
The GreyFox Ads Master Deal brings media quality, audience targeting, attention and supply optimization together in one activation across the French Open Web.
Built for trading teams seeking better campaign quality without adding more settings, deals or intermediaries.

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.
Inconsistent quality
Long-tail inventory, ad-cluttered sites and small placements can reduce the actual impact of creatives.
Fragmented audiences
Cookie-only strategies can miss valuable opportunities for incremental reach.
Complexity and opacity
Too many settings, intermediaries and hard-to-understand fees.
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.
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.
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.
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.
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.
