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 This put up options an unpublished paper that compares the efficiency of AI-generated vs. human-made photos throughout three advertising use circumstances.)

This paper describes the outcomes of three research designed to guage the efficiency of AI-generated vs. human-made photos 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 adverts
The research used AI-generated photos created with 13 text-to-image diffusion fashions, together with DALL-E2, Jasper, Midjourney v4, and a number of other variations of Secure Diffusion. Altogether, these research collected greater than 17,000 human evaluations of over 1,500 AI-generated photos.
The entire AI-generated photos in these research have 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 have been then used (with out modification) because the prompts to provide the AI-generated photos.
Listed below are abbreviated descriptions of the three research and the high-level outcomes of every research.
Examine 1 – Human Notion of High quality and Realism
The target of this research was to match the perceived high quality and realism of AI-generated vs. human-made photos throughout three advertising use circumstances – product design, social media, and print adverts.
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 assorted relying on the particular picture being evaluated and on the mannequin used to create the AI-generated picture. General, nevertheless, the research revealed that the AI-generated photos outperformed or have been on par with the human-made photos within the product design and social media use circumstances.
Within the print advert use case, the AI-generated photos have been considerably much less more likely to carry out on par with the human-made photos when it comes to perceived high quality and realism.
Once more, the scores assorted considerably relying on the mannequin used to create the AI-generated picture. So, the selection of mannequin issues.
Examine 2 – Social Media Engagement
This research’s goal was to match the power of AI-generated photos vs. a human-made picture to provide engagement in a social media setting. On this research, engagement referred to the “chance to love” a picture and the “chance to remark” on a picture.
This research included one human-made picture and 13 AI-generated photos. The researchers recruited 701 individuals who have been randomly assigned to one of many 14 photos. Every participant was requested to price how seemingly they have been to love or touch upon a picture utilizing a 7-point Likert scale (1=low, 7=excessive).
The outcomes of this research confirmed that the AI-generated photos typically carried out on par with the human-made picture when it comes to social media engagement.
Examine 3 – Click on-By way of Charges On Banner Adverts
The target of this research was to match the effectiveness of AI-generated photos vs. a human-made picture when utilized in a web based banner advert. The measure of effectiveness used was click-through charges (CTR).
This research was a randomized area 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 photos examined, the human-made picture ranked tenth when it comes to CTR. The very best-performing AI-generated picture achieved a 21.5% increased CTR in comparison with the human-made picture.
This research additionally demonstrated that mannequin alternative issues. The very best-performing AI mannequin (Secure Diffusion v1-3) outperformed the worst mannequin (Disco Diffusion) by 65.5%.
My Take
The three research described within the Hartmann et al. paper show that generative AI fashions can create visible content material that’s on par with – and infrequently higher than – human-made photos for quite a lot of advertising use circumstances.
If something, these research most likely underestimate the power of generative AI fashions to provide human-level visible content material. The prompts used to create the AI photos for these research have 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 simpler AI photos.
These research additionally most likely underestimate the standard of photos generative AI fashions can at the moment produce as a result of new, extra succesful variations of among the fashions used within the research have been launched because the research have been carried out. For instance, these research used DALL-E2 and Midjourney v4, however DALL-E3 and Midjourney v6 at the moment are obtainable.
At minimal, the outcomes of those research recommend that AI-generated photos are more likely to play an more and more essential function in advertising.
