(This yr, I am devoting a few of my Analysis Spherical-Up posts to educational analysis papers regarding the usage of synthetic intelligence for advertising functions. This submit options an unpublished paper that compares the efficiency of AI-generated vs. human-made pictures throughout three advertising use instances.)

This paper describes the outcomes of three research designed to guage the efficiency of AI-generated vs. human-made pictures used for advertising functions. Particularly, the research evaluated picture efficiency throughout three dimensions related to advertising.
- Human notion of picture high quality and realism
- Social media engagement
- Click on-through charges of banner advertisements
The research used AI-generated pictures created with 13 text-to-image diffusion fashions, together with DALL-E2, Jasper, Midjourney v4, and a number of other variations of Steady Diffusion. Altogether, these research collected greater than 17,000 human evaluations of over 1,500 AI-generated pictures.
All the AI-generated pictures in these research had been created utilizing a two-step course of. In step one, the researchers employed an image-to-text AI mannequin to create a textual description of every human-made comparability picture. These textual descriptions had been then used (with out modification) because the prompts to provide the AI-generated pictures.
Listed below are abbreviated descriptions of the three research and the high-level outcomes of every examine.
Examine 1 – Human Notion of High quality and Realism
The target of this examine was to check the perceived high quality and realism of AI-generated vs. human-made pictures throughout three advertising use instances – product design, social media, and print advertisements.
Every picture was rated by 5 human evaluators for high quality and realism utilizing a 7-point Likert scale (1 = low, 7 = excessive), leading to a complete of seven,830 scores.
The scores for high quality and realism diversified relying on the particular picture being evaluated and on the mannequin used to create the AI-generated picture. Total, nonetheless, the examine revealed that the AI-generated pictures outperformed or had been on par with the human-made pictures within the product design and social media use instances.
Within the print advert use case, the AI-generated pictures had been considerably much less more likely to carry out on par with the human-made pictures when it comes to perceived high quality and realism.
Once more, the scores diversified considerably relying on the mannequin used to create the AI-generated picture. So, the selection of mannequin issues.
Examine 2 – Social Media Engagement
This examine’s goal was to check the power of AI-generated pictures vs. a human-made picture to provide engagement in a social media setting. On this examine, engagement referred to the “chance to love” a picture and the “chance to remark” on a picture.
This examine included one human-made picture and 13 AI-generated pictures. The researchers recruited 701 individuals who had been randomly assigned to one of many 14 pictures. Every participant was requested to price how seemingly they had been to love or touch upon a picture utilizing a 7-point Likert scale (1=low, 7=excessive).
The outcomes of this examine confirmed that the AI-generated pictures usually carried out on par with the human-made picture when it comes to social media engagement.
Examine 3 – Click on-Via Charges On Banner Adverts
The target of this examine was to check the effectiveness of AI-generated pictures vs. a human-made picture when utilized in a web based banner advert. The measure of effectiveness used was click-through charges (CTR).
This examine was a randomized discipline experiment that consisted of a real-world on-line banner advert marketing campaign run on a number one show promoting platform. The human-made picture was knowledgeable photograph bought from Adobe Inventory. The marketing campaign ran December 28-29, 2022, and generated 702 clicks on 86,809 impressions.
Of the 14 pictures examined, the human-made picture ranked tenth when it comes to CTR. The most effective-performing AI-generated picture achieved a 21.5% larger CTR in comparison with the human-made picture.
This examine additionally demonstrated that mannequin alternative issues. The most effective-performing AI mannequin (Steady Diffusion v1-3) outperformed the worst mannequin (Disco Diffusion) by 65.5%.
My Take
The three research described within the Hartmann et al. paper display that generative AI fashions can create visible content material that’s on par with – and sometimes higher than – human-made pictures for a wide range of advertising use instances.
If something, these research in all probability underestimate the power of generative AI fashions to provide human-level visible content material. The prompts used to create the AI pictures for these research had been produced by an image-to-text AI mannequin, and the researchers did not modify these prompts. Prompts engineered by skilled entrepreneurs would seemingly have resulted in more practical AI pictures.
These research additionally in all probability underestimate the standard of pictures generative AI fashions can at present produce as a result of new, extra succesful variations of among the fashions used within the research have been launched because the research had been performed. For instance, these research used DALL-E2 and Midjourney v4, however DALL-E3 and Midjourney v6 are actually accessible.
At minimal, the outcomes of those research counsel that AI-generated pictures are more likely to play an more and more vital function in advertising.
