We’re proud to share that Ozone has been awarded the ‘Trust in Media Excellence’ Award at The Media Leader UK Awards 2025.
At the heart of this achievement is the Premium Web Methodology audit we conducted with PwC – designed to reassure our customers that what we say we do, is actually what we do.
Ozone’s ‘Trust in Media Excellence’ entry
Ozone is a digital advertising business with a difference. Formed through an unprecedented partnership between four of the UK’s leading publishers – News UK, Guardian Media Group, Telegraph Media Group and Reach Plc – we exist to create a better, more sustainable future for ad-funded journalism and the digital advertising ecosystem.
At our core, we are powered by the human connections created by audience-first content businesses. These are the online places where millions turn every day to be informed, inspired and entertained – and it’s those connections that fuel everything we do.
Our audience platform brings these connections together at scale, combining trusted environments, creative excellence and deep audience capabilities to deliver measurable business impact for brands. We also equip publishers with the tools, expertise and collective strength to maximise the value of the audiences they have worked hard to build.
Today, and having recently celebrated our seventh anniversary, our founding principles remain consistent, with arguably the most persistent of these being trust and transparency – ones that we believe clearly sets our business apart from other platforms and media owners in the digital advertising space.
At Ozone, trust isn’t just a value – it guides every decision we make. Since our 2018 launch, we’ve followed the guiding principle: “just because we can, doesn’t mean we should”. This belief underpins our ongoing commitment to transparency, rooted in GDPR and strengthened amid cookie deprecation, AI advancements, and evolving privacy regulations.
Unlike many platforms, Ozone was created by publishers for the collective benefit of brands, publishers and consumers. We believe trust and transparency go hand in hand – respecting data, empowering publishers with more control of their assets, and enabling advertisers to invest with confidence.
To demonstrate this, in 2024 we commissioned PwC to independently audit our business and prove what we say we do, is actually what we do. The resultant ‘Premium Web Methodology’ is a groundbreaking study, the likes of which has never been seen from any individual digital business. This six-month review inspected all aspects of our operations, with PWC’s findings confirming:
- Usage rights: Ozone correctly contracts with publishers for data use.
- Consent: All relevant consumer data used by Ozone has explicit audience consent.
- Addressability: Ozone is ready for a post-cookie era, with 83% of users addressable across sampled browsers and publishers.
- Measurement: The ‘Always On Measurement’ methodology used to measure incremental publisher value from Ozone was validated as accurate and robust.
- Segmentation: Ozone’s contextual segments are accurate 99% of the time; with behavioural segments correctly created.
- Data protections: The safeguards implemented by Ozone prevent third parties from accessing or misusing data signals outside the platform.
By voluntarily undertaking independent validation, we set a benchmark for digital transparency. At Ozone, excellence in trust means building a future-proof, sustainable media ecosystem where publishers thrive, brands achieve meaningful outcomes, and consumer data is respected. The PwC audit proves that at Ozone, trust isn’t just a promise – it’s built into everything we do. Download the report below…
