Registered IAB UK Gold Standard companies

Registered companies have not yet supplied us with all of the necessary evidence, but have registered their interest and are in the process of doing so.

The difference between IAB UK Gold Standard Certified 1.1 and 1.0
Gold Standard 1.1 was released in April 2019 with updated and more prescriptive criteria. All companies registered post April 2019 and those renewing their annual certification have been certified against these updated standards and labelled below accordingly. Take a look at the full summary of the changes from Gold Standard 1.0 to 1.1 here

Direct sellers (owned inventory)

These companies are primarily involved in the selling of advertising space that they directly own or operate, e.g. The Guardian and Bauer Media


Indirect sellers (non-owned inventory)

These companies are primarily involved in selling ad inventory on sites they do not own or operate, on behalf of direct sellers, e.g.  Google AdX and Teads


Support (Tech platforms and services)

These companies provide the tech to facilitate the buying and selling of inventory, but do not own inventory or represent specific sites, e.g. Amazon DSP and Xandr


Buyer Support

These companies buy inventory on behalf of a brand or agency, e.g. Xaxis and Unruly



These companies purchase media directly or as a representative for another company, e.g. Publicis and GroupM
