Generative AI in marketing

An unstoppable rise?

Generative AI (GenAI) is reshaping modern marketing—far surpassing simple automation to deliver intelligent, scalable, and highly personalised campaigns. As of July 2025, marketing teams across sectors have woven GenAI into daily workflows, achieving not only efficiency but also innovation and deeper audience engagement.1

This article examines early AI adoption missteps in the marketing realm, explores GenAI’s rapid evolution, highlights key trends shaping the field in 2025, and details the technologies and skills marketing professionals should prioritize to thrive in an AI‑enhanced landscape.

Early Applications of AI in Marketing: Missteps and Lessons

AI’s entry into marketing pre‑dated generative models. During the 2010s, brands deployed predictive analytics, chatbots, and automated ad placement—but many early initiatives underperformed due to weak data foundations, algorithmic bias, and limited human oversight.

A cautionary example is IBM’s Watson for Oncology, intended to tailor healthcare marketing outreach via patient data. Internal reviews revealed Watson produced “unsafe and incorrect” recommendations, ultimately leading to the project’s abandonment around 2021.2

Similarly, Zillow’s iBuying programme—powered by machine‑learning valuations—collapsed under inaccurate pricing models. Investors lost over $300–500 million before the program was shuttered in late 2021, making it a cautionary tale for AI-driven operations without sufficient human checks.3 4

On the consumer front, Microsoft’s Tay chatbot (March 2016) quickly learned and amplified hateful content from users, prompting shutdown within roughly 16 hours.5

More recently, Google’s Gemini image‑generation tool came under fire in early 2024 for rendering historically distorted or culturally offensive imagery—including non‑white figures in Nazi-era context—leading to a temporary suspension of certain functionality.6

Together, these missteps underscore the perils of hasty AI deployment: without robust oversight or bias mitigation, even high-profile projects can fail. They serve as a reminder that AI must be paired with human judgment to ensure responsible and effective outcomes.

The Evolution of Generative AI in Marketing

Following the release of ChatGPT in late 2022, GenAI quickly expanded from text generation into comprehensive multimodal capabilities, integrating image, video, audio, and text. Marketers now use these tools for creative production, real-time personalization, and analytics-driven decision-making.

By 2024, models like OpenAI’s GPT‑4o and Google’s Gemini enabled rich visual and auditory input, enabling genuinely omnichannel campaigns. AI agents capable of executing multi-step marketing workflows—such as segmentation, campaign optimization, and performance analysis—are now gaining traction. Deloitte predicts that 25 % of enterprises will deploy such agents in 2025, increasing to 50 % by 2027.7

While demand for personalized and timely content surged—growth in marketing content needs rose by 1.5x in 2023—teams only delivered 55 % of that demand. GenAI is increasingly seen as a scalable solution to this content gap.8 Many brands now emphasize transparency, bias-resistance, and explainability to comply with regulatory regimes such as the EU AI Act.

Recent surveys show over half of marketers estimate GenAI tools save them approximately one month of work each year—a testament to the technology’s maturing strategic value.

Key Trends Shaping GenAI Marketing in 2025

Making AI work for you

90% of marketers report using GenAI at work (71% weekly or more, ~20% daily).9 Organizations increasingly recognize AI as transformational rather than optional.

According to Deloitte’s 2025 outlook, success hinges on merging AI with human creativity, building trust via transparency, and evolving faster than market expectations.10 Within this environment, several trends stand out:

  • Hyper‑personalisation: Using real-time behavioral and contextual data, brands now tailor messaging dynamically. Studies report that personalisation improves engagement significantly—with personalization leaders 48 % more likely to exceed revenue targets, and 75 % of consumers preferring brands delivering tailored content.11
  • Human‑AI collaboration (“Centaur Model”): Many firms now have AI draft roughly 30 % of outbound content, which is reviewed by humans, combining efficiency and oversight.
  • Search and analytics transformation: With third-party cookies deprecated, GenAI powers voice search, content mapping, and predictive analytics. Smart Insights finds ~64 % of CMOs are deploying GenAI for analytics and search functions.12
  • Ethical AI and first‑party data strategies: Growing privacy concerns have pushed brands toward collecting and relying on first-party data. Microsoft sources suggest that 86 % of executives expect GenAI to significantly boost content output in the coming year.13

Other trends include GenAI-supported campaign orchestration and trend forecasting. Gartner anticipates that by end‑2025, GenAI will contribute to no less than 30 % of content discovery workflows. Platforms like Hootsuite now promote AI-generated viral content as central to their strategy.

Technologies and Skills Marketers Should Prioritise

Success in GenAI-enabled marketing demands not just tools, but competencies:

Core Platforms:

  • GPT‑4o (OpenAI) – state‑of‑the‑art NLP with multimodal inputs
  • Gemini (Google) – strong in multilingual, visual, and audio outputs
  • Claude 3.5 – supports complex, structured agentic workflows
  • Adobe Firefly – AI-enhanced creative media for design teams
  • HubSpot AI / Jasper – copywriting, CRM automation, email optimization
  • Salesforce Einstein – predictive analytics integrated into marketing platform

Key Skills:

  • Prompt engineering – crafting nuanced inputs that produce effective AI responses
  • Data literacy – interpreting AI outputs and making informed strategy choices
  • Tool fluency – selecting, integrating, and optimizing the right stack
  • Ethical AI usage – understanding bias, consent, fairness, and compliance
  • Strategic alignment – ensuring AI initiatives support broader business goals

Despite surging demand, training gaps persist. McKinsey’s 2025 “Superagency in the Workplace” report reveals that while most companies use AI, only about 1 % consider themselves AI‑mature. Many employees still lack the AI training needed to fully exploit GenAI’s potential.14 Organizations prioritizing both talent and technology are those most successfully capturing long‑term value.

Final thoughts

Generative AI isn’t a passing trend—it’s a paradigm shift in marketing operations. By learning from earlier failures, leveraging modern GenAI capabilities with integrity, and preparing strategically for future innovation, brands can not only work faster but work smarter.

The path ahead requires responsible innovation, continuous upskilling, and enduring human oversight. These elements together will define marketing success in the GenAI era.
