By The browser that built its brand on blocking your ads is now selling its own. And the measurement model is unlike anything in your current stack.
Brave, the open-source browser that strips third-party cookies, kills tracking pixels, and blocks Google Analytics by default, has been quietly building an ad business. It started with opt-in rewarded notifications in 2019. Then it acquired search engine Tailcat in 2021. Now it runs search ads and new-tab takeover display ads across a browser with 100 million monthly active users) as of late 2025.
The kicker: none of it runs through programmatic pipes.
How the targeting actually works
"It's not programmatic," Jean-Paul Schmetz, Brave's chief of ads (who also serves as CEO of Ghostery), told AdExchanger. "It's not trying to figure out that you were looking at gloves on Amazon 10 minutes ago, so I'll give you an ad for gloves."
The targeting inputs are minimal:
- For search ads: the query itself plus the user's country. That's it. No demographic overlays, no behavioral segments, no alternative IDs.
- For new-tab takeover display: country only. No query signal at all.
"If you type 'buy lipstick,' I don't care if you're a man or woman, I'll give you a lipstick ad," Schmetz said. "If you want to go to Amsterdam, I don't care if you're rich or poor, we give you all the hotels."
No third-party cookies. No UID2, no RampID, no ID5. The browser never shares user data with third parties. Brave doesn't use or accept any alternative identity solutions.
What buyers can measure (and what they can't)
This is where it gets interesting for anyone running a measurement program. Brave functions as both browser and ad server, which means it can track conversions without any tags on your site, but only within its own walled garden.
Here's what the Brave Ads reporting dashboard gives you:
- Impressions, clicks, CTR across all ad formats
- Site visits (defined as 5+ seconds on the landing page with the tab active) for notification ads
- Conversion tracking with click-through and view-through attribution
- A 30-day conversion window
The conversion mechanism works at the browser level. When you click a search ad, the browser stores the advertiser's conversion page URL locally. If you reach that page within 30 days, the browser pings a Brave-operated server with an anonymous report. Brave aggregates these reports and delivers a count to the advertiser. No cookies, no pixels, no JavaScript tags required.
But the data flowing back is aggregate only. You get a count of conversions, not user-level paths. There's no frequency data across campaigns, no cross-device graph, no audience overlap reporting. Your multi-touch attribution model doesn't work here because there's nothing to stitch.
And here's the part that will frustrate your analytics team: Brave blocks Google Analytics, Adobe Analytics, and most third-party measurement tools by default when they're hosted on their own domains. First-party analytics implementations (self-hosted GA4 or Adobe on your own subdomain) still work. But if you're relying on standard third-party tracking, Brave's browser will kill it before it fires.
The scale question
Brave reported 1.29 billion search queries in January 2025 and 80 million monthly active users at that time, growing to 100 million MAU by late 2025. Search ad click volume grew 15x over 2024, according to the company.
The advertiser roster is real. Brave says over half of the top 20 largest paid search advertisers worldwide buy Brave Search Ads, listing Amazon Ads Sponsored Products, B&H Photo, Booking.com, CompareCredit, NerdWallet, StubHub, and Wayfair as customers. Nine out of ten advertisers who started campaigns in 2024 continued buying in consecutive months.
Search ads are currently available in the US, Canada, UK, France, and Germany.
What this means for your Monday morning
Brave's model is a direct challenge to the assumption that more data equals better targeting. Query-based intent is arguably the strongest signal in advertising. Google built a trillion-dollar company on it. Brave is running the same play with radically less infrastructure: no audience graph, no behavioral modeling, no bid optimization against user segments. Just the query and the country.
For performance buyers already maxing out on Google Ads, the pitch is incremental reach among a tech-savvy audience that's invisible to your existing campaigns because they've blocked your measurement stack. Some brands reportedly see up to 5% growth on total paid search spend while maintaining ROAS targets, according to Brave's own reporting.
The measurement trade-off is real, though. You're buying into a closed system where Brave is the browser, the search engine, the ad server, and the measurement layer. You have to trust their aggregate conversion counts because there's no way to independently verify them with your own tracking. That's a familiar bargain if you've bought walled garden inventory before, but it's unusual for search.
If you're evaluating Brave as a channel, start by checking whether your first-party analytics survive the browser's blocking. Navigate to your landing page in Brave, open the Shields panel, and see what gets killed. If your measurement stack depends entirely on third-party hosted scripts, you'll be flying on Brave's dashboard numbers alone.
The practical recommendation: test it as an incremental search channel with a dedicated conversion URL, measure against Brave's own reporting for 60-90 days, and compare the CPA against your Google baseline. Don't try to fold it into your existing multi-touch model. It won't fit.
