WEMF / KS Circulation Certificate

The official circulation figures of the Swiss press


The WEMF / KS  circulation certificate provides the official circulation figures (printed and online) of the Swiss press


The certification of circulation carried out by WEMF ensures that the circulation figures (printed and online) of the Swiss press (newspapers and magazines) are determined according to the same criteria per category and are thus comparable. In this way, it provides objective information for advertisers, management, publishers and editors. The advertising market uses the figures for the qualitative assessment of press titles as well as for media selection. Media companies use the key figures to monitor the competition, to promote titles and to sell advertisements. The advertising industry associations expressly recognise the WEMF / KS-certified circulation figures as the sole officially valid ones.

Published once a year, on 1 September.
