Sound research for effective outdoor advertising

For over 20 years, APG|SGA has been researching the impact of out-of-home campaigns and developing practical research tools for planning and optimisation. The findings from this ongoing research form the basis for efficient and measurable campaigns in public spaces.

The specially developed Poster Performance Index (PPI) is now an established post-test in Swiss outdoor advertising.

  • Extensively proven impact: impact is determined based on “recall”, “brand recognition” and “appeal”. Advertisers can use these findings in the further development of their campaigns.

  • Practical benchmarking and control instrument: combined with quantitative performance values (reach, OTS, GRP and CPM), the PPI offers insights into the efficiency of advertising spend.

  • Exclusively for APG|SGA customers: the PPI is an established post-test for poster campaigns and an exclusive element of the APG|SGA service offer. For poster campaigns with a net value of CHF 250,000 or more, this test is conducted free of charge, on request and subject to availability.
