Ad-hoc audits

Post-tests, barometers, trackings, marketing mix modelling, many tools are available to measure the effectiveness of advertising campaigns. These are the tools among others that CESP audits in order to ensure transparency and bolster the confidence of communications professionals in the research conducted.

First audit of a Marketing Mix Model
Marketing Mix Models are widely used by advertisers to quantify the impact of their communication mix. The media also use them more and more in order to demonstrate their benefits for the brands. Therefore, ACPM (Print JIC), Google and SNPTV (Association of TV groups) have supported the audit of Ekimetrics’ Marketing Mix Models.

366 has asked CESP to audit its ‘366 # Panel’ proprietary tool that was set up and has been managed by Kantar TNS since 2015. This tool is used continuously by the sales house to conduct: principally post-tests to measure the effectiveness of the print and digital campaigns of their clients, but also ad hoc surveys to understand socio-cultural and consumer trends. The sales house wanted to boost its clients’ confidence in this tool.

CESP Visa Efficacité (literally “Ad-Effectiveness Visa”) was set up by CESP at the behest of the Union des marques (the French Federation of Advertisers), in order to validate that campaign effectiveness surveys and tools are aligned with some methodological prerequisites. Once a survey or tool gets the Visa, it is published in Le Référentiel(literally ” the Toolkit”), which is the first platform dedicated to Ad-Effectiveness measurement, launched by the Union des Marques in 2019.

Visa Efficacité objectives


Check respect
of methodological

best practices

CESP Visa Efficacité is based on 5 dimensions:

–    Survey methodology design
–    Sample representativeness
–    Ad effectiveness indicator definitions
–    Result accuracy
–    Relevance of external and exogenous data injection


Controls are conducted through quaterly waves.

Sales houses, media agencies and research agencies can apply for surveys (conducted once a year or less) or for tools (surveys with exactly the same research design used several times per year).
