"You should never assume that, um, it's forever"

Pierce Cook-Anderson is Managing Director of Advertising at Mail Metro Media, the commercial home of the Daily Mail, Metro, i and New Scientist. He returned to publishing after two decades that took him through media sales and the sell side of ad tech, and now leads the title's response to AI, zero-click search and the fight for fair value in return for its journalism.

Cook-Anderson began his career 21 years ago as a journalist researcher on the features department of the Mail on Sunday, but quickly found he was drawn to the business of publishing more than to journalism itself. He found Future publishing on his own initiative and spent a decade in media sales, working across Future, Sky, the FT and Newsweek, where he first saw revenue move from direct deals into ad tech through partners such as Teads and Kiosked.

Deciding to follow the money, Cook-Anderson moved into ad tech with OpenX as an SSP during the rise of header bidding, then joined Smart Adserver as UK country head as it became Equativ, before moving into sell-side curation and first-party data enrichment with Audigent, which he says was acquired by Experian at the end of 2024. Roughly 21 years after he started, he returned to publishing as Managing Director of Advertising at Mail Metro Media, where he argues that trusted journalism is the scarce and valuable thing in an AI-driven market, and that publishers must be paid fairly for it.

How Pierce thinks 03 convictions
01 Trusted media pays back

"Brand performance is better, return on ad spend is higher when you have news brands involved"

Cook-Anderson's commercial argument is that trust is not a soft virtue but a measurable premium. He points to feedback that news publishers are the most trusted content sources alongside linear TV, and to studies showing brands perform better when they sit beside that journalism. In his view the value flows from the fact that people deliberately seek out authoritative sources.

02 Fewer, deeper partners

"We've reduced the amount of partners we work with before my arrival by about 50%"

Cook-Anderson has cut the number of ad tech partners and ads.txt entries by roughly half without losing money, and he frames that as a deliberate move to fewer, more trusted relationships. He argues that what wins now is collaboration, insight and ease of use rather than a transaction settled by a monthly cheque. The value, he says, is mutual or it is not worth having.

03 First-party data depth

"We have something like 200 billion data points"

Cook-Anderson says the sophistication of the publisher's own data surprised him even after a decade working with it from the ad tech side. He describes around 200 billion first-party data points feeding outcomes deals, guaranteed campaigns, commerce and local targeting, worked through a DMP for cohorts and intent. His conclusion is that efficient, direct data work is something only a publisher should really be doing.
