Safe for your brand.
Respectful of your readers.
Keystone gives you fast, precise control over where ads run, while keeping the measurement free of cookies and personal identifiers.
Respond to a policy flag in seconds, not a deploy cycle
When a page needs to stop showing ads, it shouldn't take a release.
Blocked pages
Block up to 10,000 exact URLs per site. Paste them, or upload a Google Ad Manager Policy center export as-is. It applies within seconds, and no ad request fires on those pages.
Linked domains
The tag only runs on the domains you authorize, so a copied tag does nothing anywhere else, helping prevent domain spoofing.
Page rules
Keep formats off whole sections with URL rules: only on these pages, or never on them.
Policy-compliant formats
Every format is designed with Google's publisher policies in mind, from how ads are sized to where they're allowed to appear.
Your site keeps working
If anything on our side fails, your page loads normally. At worst, an ad doesn't show, and your content is never affected.
Google Certified Publishing Partner
We work within Google's publisher policies every day, as one of a select group of certified partners.
Respects your readers' privacy choices
Every format follows the choice your reader makes in your consent banner, automatically.
One choice, applied everywhere
Your reader decides once in your consent banner, and every Babel format respects it. Without consent, they only see non-personalized ads.
Your page never waits
If your consent banner is slow to respond, your page keeps loading. Nothing gets stuck waiting on us.
Babel's measurement is cookieless
Our own reporting sets no cookies and stores no IP address or user ID.
