Posters have a lasting impact






Management Summary

Recall, brand recognition, appeal

In the period from 2000 to 2013, a total of 962 poster campaigns were assessed with Poster Performance Index PPI as regards their advertising impact. The results confirm the remarkable quantitative performance of posters according to SPR+ Swiss Poster Research Plus. On average, across all campaigns, posters scored 45% for recall, 62% for brand recognition, and 64% for appeal. In line with various other studies, the PPI figures show that high advertising pressure – measured in GRP as a combination of reach and opportunities to see – generates a high qualitative impact. Recall, brand awareness, and popularity of poster advertising call for good, efficient, eye-catching visual designs. The examples from the PPI best-performers list clearly document this thesis.



Real-world monitoring and benchmarking tool



Scope and objective of study
The Poster Performance Index PPI measures the advertising effectiveness of poster campaigns according to three criteria:
-    Recall (aided)
-    Brand recognition
-    Campaign appeal

The PPI is a service tool for APG|SGA customers. For the advertiser, it is a convenient monitoring and benchmarking instrument that in addition to the customary calculation of reach, opportunities to see (OTS), advertising pressure (GRP) and cost per 1000 OTS (CPM) 1 as quantitative metrics also allows a rating of the qualitative effectiveness of poster-based communication. The PPI study relies on recurring surveys whose results are systematically integrated in a database differentiated by industry. The constantly growing breadth of the database enables advertisers to continually enhance the efficiency of their poster communication.

Encouraging results
On average across all 962 campaigns tested to date and across all target groups, recall ratings are 45%, brand recognition 62%, and appeal 64%. Differentiated by age bracket, the youngest segment performs significantly best with 52% recall. This means: On average among the youngest interviewees aged 15 to 29, posters generate the highest recall ratings.

Key elements: Visual design and advertising pressure

Factors that influence advertising impact

Advertising pressure
Increasing advertising pressure has a measurable influence on advertising impact. As shown in the graphic at the bottom, average recall continuously rises with increasing GRP and at over 5000 GRP attains the highest value of 51%. On average across all measured poster campaigns, no clear patterns can be discerned with respect to brand recognition. Primarily, the design of the visual is what influences whether or not a person can associate the correct brand with a remembered campaign. The graphic at the bottom right illustrates the causal relationships.

Visual design
Good posters rely on the principles of human perception. They are simple and focused, distill the image and text messages to a few memorable elements that even the casual observer can recognize as relevant and commit to memory. The responsibility for the artwork lies with the advertiser or with the mandated advertising agency. Various pretest methods available through market research institutes make it possible to gain important insights as regards perception and acceptance of an advertising message in the early planning stages of a campaign.


1 Gross rating points GRP as the unit for advertising pressure are obtained by multiplying reach with contacts per person; the number corresponds to the total number of contacts per 100 persons in the target area (reached or not reached).



Interaction of visual design and advertising pressure
Impact (I) = Message (M) + Transport (T)

A confrontation with a poster establishes the direct contact between its featured message and the audience which includes the target group. A message will be correctly delivered if it is not only correctly transported but also correctly perceived. For this reason, the optimized cooperation between the customer (sender of the message) and APG|SGA as the provider (transporter of the message) is crucial. As is the case for every advertising measure, the impact of a poster campaign also depends on numerous other factors. They include exogenous influences such as the state of the economy, climate/weather, exchange rates, and competitive activities as well as endogenous factors involving marketing measures such as pricing.








From the PPI best performers list


Posters are always successful
Differentiated by industry, the PPI averages measured for poster campaigns often vary considerably. This is due to the different degrees of complexity of the advertised products and services. With a clever strategy and artwork focused on the essence, however, it is possible to achieve outstanding results with poster advertising in every industry. The recall ratings of the visuals presented here support this claim. They are the currently valid peak values achieved in the course of the years in 12 different industries.
