Information for Ad Age Agency Report 2023 came from questionnaires submitted by agencies and agency companies and from analysis and estimates by Ad Age Datacenter.

Effective with Agency Report 2023, agency listings are no longer rankings because listings exclude agencies owned by a number of major agency companies that don’t disclose revenue by agency or network. Given changes in how agencies, networks and agency companies go to market, Ad Age no longer publishes revenue estimates for those agencies and networks.

Ad Age expanded Agency Report’s online Ad Age Agency Family Trees 2023 to include additional content related to organic growth, disciplines, geographic revenue, client sectors and number of employees for agency companies where available based on financial disclosures and information provided to Ad Age by the companies.
Ad Age’s ranking of the world’s 25 biggest agency companies is based on revenue.

Agency and network figures generally are modeled on reported or estimated net revenue (revenue less pass-through costs). Pass-through costs include third-party vendor costs, production costs, media costs and out-of-pocket expenses that are charged directly to clients.
WPP, Publicis, Interpublic and Dentsu disclose both revenue and net revenue (or a figure similar to net revenue). Those four companies emphasize net revenue (or a figure similar to net revenue) as a measure of performance. Omnicom only discloses revenue.
