Domain Trust Gate: new and expired domains

Walled gardens such as Google and Microsoft are strict about the sites advertised through an account. If your platform sends ads for a brand-new or unsafe domain, your ad accounts can suffer.

What the Domain Trust Gate does

The Domain Trust Gate plugin ($1,490) holds new and unsafe websites before they reach Google, Microsoft and other walled gardens, so your accounts stay in good standing. Stopped automatically:

  • Domains younger than 90 days
  • Expired domains
  • Safe Browsing hits

It adds automatic strikes and blocks for repeat offenders.

Who needs it

Operators who sell walled-garden channels — through the channel connectors or Omnichannel Buying — to many self-serve advertisers. One bad advertiser can put an account at risk for everyone.

What to tell a held advertiser

  • Their site is too new, expired, or flagged by Safe Browsing.
  • The hold protects the walled-garden accounts every advertiser on your platform shares.

On programmatic

Separately, the DSP flags newly registered and rotating domains on advertiser landing pages (release v8.1).
