Your platform buys from supply partners connected to AdTech Europe technology. The Publisher Policy sets the rules they must follow. Knowing it helps you explain to advertisers why some sources are blocked.
Inventory that is not accepted
- Sites or apps with illegal content, piracy or malware.
- Hate, violence or content involving minors.
- Inventory that misrepresents its domain, app, format or location.
- Sites built only to show ads, with little or no real content.
Traffic quality rules
- No bots, click farms, incentivised clicks or auto-refresh abuse.
- No hidden, stacked or off-screen ads.
- No forced clicks, pop-ups that can't be closed, or misleading placements.
- Bid requests must carry accurate data: domain or bundle, device, IP, user agent and supply chain (schain).
Transparency
Supply partners must keep valid ads.txt / app-ads.txt and sellers.json entries and pass a complete supply chain object.
What happens when a source breaks the rules
Traffic is checked before the bid and after delivery. Placements that fail are blocked, often automatically. Traffic found to be invalid is not paid and may be deducted from later payouts; breaches can end the partnership.
If you bring your own supply partners, hold them to the same standard in your own agreements.
