Future-proofing audience strategy with privacy-first identity.

AdFixus for Advertisers

Deep dive: data loss, first-party identity, AdFixus

In today’s privacy-first digital landscape, your site visitors are your most valuable asset. First-party data goes beyond just post-registration PII — it includes rich behavioral signals, intent, and engagement patterns across your properties.

The deprecation of third-party cookies and browser tracking limitations have degraded this data stream. Marketers and publishers face growing signal loss, making it harder to recognize, engage, and activate audiences effectively.

The solution is to rebuild and strengthen your first-party data foundation. Collecting and owning audience data directly lets you regain control, increase addressability, and unlock the full value of your audience across all digital touchpoints.

With a robust first-party identity strategy, you can unify anonymous and known users into actionable segments, collaborate with publishers, and future-proof audience strategies against privacy regulation changes.
‍
First-party is not the fallback — it’s the way forward.

Simple integration across your existing MarTech makes it easy to extract more value from investments. See our Integrations section for guides.

FAQ's

Frequently Asked Questions from Advertisers

FULL FAQ's

Can AdFixus reach my full audience across multiple domains?

Yes. AdFixus reconnects fragmented audiences by creating a consistent, privacy-safe ID across your owned and operated domains, something third-party cookies can no longer deliver.

What makes AdFixus different from other identity solutions?

Unlike others, AdFixus does not rely on personal identifiers, probabilistic fingerprinting, or rented identity graphs. Instead, we offer a deterministic, privacy-first identity framework that balances audience recognition with compliance and user trust.

What solutions existing for identity creation and why not just build it in‑house?

Building an ID internally is possible, building an ID that is viable across domains or connecting externally is not. You’ll need to understand and keep abreast of all browser changes and updates and also replicate patented double‑encryption, CDN routing & fail‑over architecture (multi‑AZ, 99.99 % SLA).

Ongoing upkeep > $500k / yr in DevOps & security.

AdFixus ships as a managed SaaS and re-invests a significant proportion of our resources and time on maintenance and updates that benefit the whole.
