Advertising impact research Formal factors such as size, colors or length have a strong influence on the impact of advertisements and commercials - knowledge of these influences and their orchestrated interplay optimize advertising messages.If you want to bring some order into the multitude of factors that influence the impact of advertising, it is advisable to first distinguish between content and formal factors of advertising impact.The content factors include the reference of the advertisement to the product, the qualitative design of an advertisement and the creativity of the presentation - these are influences that are difficult to put in a row. Content-related qualitative factors are tricky for research. They are difficult or impossible to quantify and often impossible to identify.
Research is easier with formal factors such as ad size, spot length, switching frequency, use of color in ads, magazine size or placement in the magazine. They offer the advantage that they can be measured quite easily, as can their impact.
What is the result of all these measurements? For decades, most of the formal factors of advertising impact were boundlessly overestimated. Moreover, they were considered the hobbyhorses of researchers and the favorite children of advertisers, who sometimes attributed immense importance to them. In reality, however, many formal influencing factors play a rather subordinate role. But not all of them. It is important to separate the wheat from the chaff.
For example, the size of the advertising medium is important. The findings here are clear. Common sense tells us that. Large ads have a greater impact than small ads. Large posters attract more attention than small posters. But beyond these truisms, the crucial question is of course: does an ad twice as large have twice or even more than twice the effect? Or expressed in francs: Does a large and correspondingly more expensive ad have a greater impact if it costs more? In other words, is it worth the money?
Advertising research has been looking for answers to this question for over a hundred years. In 1908, the American psychologist William D. Scott discovered that large advertisements are noticed disproportionately more often than small ones. A half-page ad attracts around three times as many glances as a quarter-page ad. Based on similar studies, the German advertising researcher Theodor König came to the following conclusion in 1926: "Whoever pays for an eighth of a page thus receives by far not the eighth part, but barely the twentieth part of the psychological influence that a full page produces."
Overall, the research results on the influencing factor of ad size are quite contradictory. The exact correlation between the increasing size of ads and the resulting increase in attention, recall, recognition or advertising effectiveness varies considerably:
- Numerous studies have come to the conclusion that there is a constant correlation between ad size and ad attention. All the evidence suggests that this is not entirely true.
- Other studies have shown that the increase in attention is less than proportional to the increase in format size. This means that the law of diminishing returns generally applies to the advertising effectiveness of different ad sizes.
- Similarly, the increase in effectiveness with increasing ad size is not proportional, but disproportionately low. However, the specific impact curve is sometimes steeper and sometimes flatter, depending on the advertising problem. While the increase in effectiveness is relatively high for smaller format sizes, the additional gain is always smaller for large formats.
Strong Starch formula The American media and advertising researcher Daniel Starch investigated the relationship between ad size and recall and came to the conclusion that the proportion of people who remember
can be predicted from the proportion of people who can remember a half-page ad using a simple formula (the Starch formula): if 10 percent of the readership see a half-page ad, a full page generates an additional 10 percent of the rest of the readers - so it is remembered by a total of 19 percent of readers. The increase with a larger format is therefore disproportionately low.
If one tries to reduce the sometimes contradictory findings to a common denominator, one thing is certain: Large advertising media generally work better than smaller ones. In reality, however, there are many exceptions to this rule. In most cases, the increase in effectiveness is disproportionately lower with increasing size, which means that the increase in effectiveness is often achieved at a high price.
By analogy with ad size, the same principles also apply to spot length. Long commercials are generally more effective than short commercials, but not in every case. Two short commercials can sometimes be better received by the television audience than one long one. Here, too, the law of
formal advertising impact factors: by extending or doubling the length of the campaign, a disproportionately low increase in impact is achieved in the best case, rarely more (see box on p. 9).
There are also reliable findings on the subject of "magazine size". For example, a long-term comparison of copy test results of the magazine Hörzu published in 1991 under the title "Qualitative Resonance Analysis" examined the influence of magazine size, among other things. The study came to the following conclusion: There is less competitive pressure for the advertised product in thin magazines with fewer advertisements. Thick magazines are picked up more often, however, as they contain more reading material. The first argument speaks for higher recall values in thin magazines, the second for higher recall values in thick magazines.
The figures from the Hörzu copy tests did not reveal any significant differences. It is possible that the two opposing influences - competitive pressure versus repeated reading - cancel each other out.
A large part of the empirical research results on the factors influencing advertising can be dispensed with - at best, they produce contradictory findings. The key to explaining the significance of formal factors lies in the so-called orientation reflex.
The main thing is stimulatingPerceptual psychology describes a reflex-like, involuntary reaction to activating stimuli as an orientation reflex. It adjusts the organism to the stimulus, sensitizes the information system and increases the supply of information from the entire environment. The more intense a stimulus is, the more likely and the stronger the orientation reflex becomes. The reaction does not depend on the person themselves at all, but solely on the stimulus.
The orientation reaction is largely automatic. It is determined in particular by the following aspects of a stimulus:
Intensity, color, size, novelty, uncertainty. Color in particular triggers strong orientation reactions and automatically attracts the viewer's attention.
Similar reactions can be expected from all stimuli with strong activation potential. In advertisements, the strongly activating elements are fixed on average around 40 percent more frequently than the weakly activating elements.
There are essentially three
Properties of stimuli that trigger the orientation reflex:
- Everything that is new, conspicuous, unfamiliar and surprising leads to an orientation reaction.
- Everything that is important to a person and promises very pleasant or very unpleasant experiences.
- And above all: everything that is loud, shrill, garish, large or colorful. This applies in particular to the colors yellow, orange and red.
Colorful ads with bold colors are therefore generally more effective than ads that are gray in gray.
come along. But their effect naturally fizzles out in a print world where everything is colorful. Black and white is more striking.
Insignificant choice of placementThis orientation reaction also explains why some other formal factors of advertising impact are rather secondary. Placement, for example. Whether an ad is at the top right or bottom left of a page, whether it is at the front or back of the magazine, is relatively insignificant for its impact. In any case, there are far more important aspects of advertising impact than placement.
When it comes to placement, researchers have long racked their brains over a very strange phenomenon. Hundreds of studies conducted worldwide have repeatedly confirmed the fact that the advertising impact of advertisements in print media is virtually independent of their placement in the editorial environment. In any case, there are stronger factors influencing advertising impact than the editorial environment. It is therefore relatively irrelevant whether an advertisement promoting schnapps is placed next to an article about how a circular saw works.
The program environment on television and radio, on the other hand, has a completely different effect. The program environment is decisive for the effectiveness of a TV or radio commercial. Virtually all studies that have looked into this topic agree on this. If spots are placed in an unfavorable environment, their effect largely fizzles out.
The key to the explanation is provided by the construct of "psychological-emotional closeness": someone watching a romantic movie is not "receptive" to a commercial advertising the use of a vacuum cleaner. Anyone who follows the plot of an action movie spellbound has no interest in oatmeal.
What promises very pleasant experiences triggers an orientation reflex in people: Diesel's eye-catching display.
30 seconds feel like 75 percent of 60 seconds
Comparative studies on the different effectiveness of 30-second and 60-second television commercials in the USA have produced the following findings:
- On average, 30-second spots achieve around 15 percent lower spot awareness than 60-second spots.
- 30-second spots achieve the same motivational effect as 60-second spots.
- 30-second commercials are more effective with younger viewers than with older viewers.
- Two 30-second spots achieve considerably higher effects in terms of spot awareness and knowledge of the advertising content than a 60-second spot that is only used once.
- 60-second commercials are often "rejected" more than 30-second commercials - and always when the advertising content is repeated too often in the 60-second commercial.
- 60-second spots are often more effective than
30-second commercials for the launch of new brands,
or when thematically new and relatively complicated
Advertising messages should activate the advertising of a brand.
- The comprehensibility of the advertising texts does not suffer if the time is reduced from 30 seconds to 24 seconds.
- The effect of a 10-second spot is 78 percent of that of a 30-second spot in terms of changing brand preference and 60 percent in terms of recall.
- All in all, the overall effect of 30-
seconds spots have about 75 percent of the effect of 60-second spots.

Less spot time often brings the same amount of attention.
