In a groundbreaking development, advertisers are increasingly leveraging artificial intelligence (AI) to create highly personalized online ads that resonate on an individual level. This shift towards tailored advertising is reshaping how brands connect with consumers, as evidenced by the innovative work of Cheil UK in collaboration with the startup Spotlight.
Imagine scrolling through social media and encountering advertisements that not only reflect your favorite colors and music but also use phrases that echo your own speech patterns. This is the essence of the new AI-driven approach to advertising, which seeks to enhance user engagement by understanding and adapting to individual personality traits.
AI-Driven Personalization: The Future of Advertising
Cheil UK has partnered with Spotlight to harness the capabilities of large language models. These models analyze user behavior across various online platforms—including social media and search engines—to construct a profile that reflects an individual’s personality. By adapting the tone, pace, and even visual elements of ads, brands can target users with content uniquely suited to them, moving beyond traditional demographic segmentation.
Brands in diverse sectors such as retail, automotive, insurance, and banking are already employing this technology to engage consumers more effectively. The AI tools evaluate users’ online interactions, including posts on public forums like Facebook and Instagram, as well as their search histories and data entered into platforms like ChatGPT.

The AI systems can discern emotional states, offering insights into whether a user might be feeling happy, sad, or experiencing other personal situations. This depth of analysis aims to create a more engaging advertising experience for consumers.
Challenges and Ethical Considerations
While the potential for AI-personalized ads is significant, there are concerns about the implications of such targeted marketing. Critics like Alex Calder, chief consultant at AI innovation consultancy Jagged Edge, question whether the focus should be on creating ads that appeal to individual tastes rather than crafting powerful, memorable mass-reach campaigns. Calder argues that overly personalized ads could become “creepy,” especially if they overtly reference intimate details of a consumer’s life.
Ivan Mato from brand consultancy Elmwood raises similar concerns about consumer acceptance and regulatory reactions to the surveillance necessary for such advertising strategies. The ethical use of AI in marketing is a pressing issue as brands navigate the fine line between personalization and privacy invasion.
Despite these challenges, the advantages of AI-driven personalization are compelling. Research has shown that tailored advertising text, even when generated by AI like ChatGPT, can be significantly more persuasive. A study involving an iPhone advertisement revealed that consumers responded more favorably to ads that featured personalized text aligned with their personality traits, resulting in higher engagement rates.
However, experts like Jacob Teeny, assistant professor of marketing at Northwestern University’s Kellogg School of Management, caution that while AI excels in targeting, true personalization in creative content still has room for growth. The future of digital advertising may depend on brands striking a balance between effective targeting and ethical considerations.
As AI continues to evolve, its role in advertising will likely expand, addressing persistent issues like digital advertising wastage—where an estimated 15% of ad spending goes unseen. Personalized ads represent a potential solution to this problem, promising a more efficient allocation of marketing resources.
Ultimately, the landscape of advertising is changing rapidly as AI technologies develop. The ability to create personalized, engaging content tailored to individual consumers represents a significant opportunity for brands, but it is crucial to pursue these innovations ethically and transparently.
