Amy Lawrence, Head of Digital, EMEA, Publicis Imagine & Chair of the IPA Digital Marketing Group, said:

"It is always fascinating to see which media owners perform best in the IPA Digital Media Owners Survey and are committed to providing a consistently excellent service. I am delighted to see such high standards across the board, as it highlights that so many media owners are committed to working together effectively with their agency partners. Particular congratulations must go to Blis for topping the Autumn 2025 survey.”

The IPA Digital Media Owner Survey is released twice a year, in spring and autumn. Every January, agency members of the IPA Digital Media Group are asked to provide a list of their top trading partners from the previous year – no sensitive revenue data is shared. These individual lists are then aggregated to form a survey of the top 25 media owners for both the Spring and Autumn surveys of that year. Each year, there is a degree of churn in which vendors appear on the questionnaire and others, therefore, drop off. Featuring on the survey questionnaire is therefore a factor of scale, especially relative scale, rather than service levels.
