AdFixus for Publishers

Deep dive on identity, cookies, and AdFixus' approach

With third-party cookies disappearing, it’s critical to build accurate, compliant, and interoperable methods for creating ad products that measure outcomes. This is the only way to compete with walled gardens and protect against the incoming wave of AI intermediaries.
‍
Many publishers have expanded into multiple brands, domains and geographies — which fragments audience management. The addressable audience enables you to personalise across domains and increase ad yield for advertising partners.
‍
AdFixus provides a patented first-party cookie platform that helps publishers sync anonymous users into a durable, non-PII identifier. The cookie is decentralised and stored in the user’s browser — giving publishers privacy-first addressability and proven results.
‍
AdFixus Match — Connect advertiser audiences to publisher audiences with offline + real-time ID matching, without sharing PII. Fast, secure, and compliant.

Revenue growth

100% addressable audience

Giving you the ability to reclaim the signals across all browsers and all your associated domains consistently.

100% deterministic

we deploy a unique double encrypted first-party cookie into a individual’s browser. We do not have any algorithmic matching or fuzzy logic to attempt to match an individual to signals seen elsewhere.

Increasing audience segments

through our solution and our ability to reclaim all of your addressable audience we will subsequently increase your segment sizes. In some markets with a large non-Chrome footprint, we have seen a 2x increase in segments.

Increasing campaign efficiencies

increasing data into your ad servers increases all campaign and super charges the optimisation models and algorithms.

Increasing campaign effectiveness

larger segments equal larger targeting abilities. Our partners have increased campaign fulfillment rates from 60% to 95% - significantly reducing ‘make goods’.

Increase campaign operations

where clients have a single ad server deployment, they can also gain efficiencies across their network to enable frequency capping.

Conversion API

allows publishers and advertisers to have a real-time flow of audience IDs to qualify individuals in and out of segments to better optimise campaigns.

Increase your attribution

Current reporting is only capturing click conversions – yet your audience is reading content around a particular topic, not to search for and buy a particular product. You are losing out in the attribution game. Claim back the value you bring.

Future proof against industry changes

The future of digital identity demands resilience, privacy, and adaptability. See how AdFixus is helping businesses future-proof against the next wave of industry change.

Safari and Cookies

Safari’s blocking of Third-Party Cookies and Apple’s Intelligent Tracking Prevention (ITP) has had serious impacts on existing vendors and custom build solutions, impeding identification.

 Privacy Legislation

The continual changes to Privacy Legislation across the globe are putting greater restrictions on data – especially on consent, storage and sharing.

Data breaches

The risks of data breaches associated with PII Data has risen dramatically and businesses are facing serious fines.

FAQ's

Frequently Asked Questions from Publishers

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.

What makes AdFixus different in one sentence?

AdFixus is a deterministic, first‑party, double‑encrypted and shareable IDs you own fully: no emails, no fingerprinting, no rented graph.
