The top 10 themes reflect where advertiser attention truly moved in 2025.

New data shows traditional SEO success no longer guarantees visibility inside generative AI answers. Ahrefs found that fewer than 9% of ChatGPT and Gemini citations come from URLs ranked in Google’s top 10 results—meaning more than 90% of high-ranking organic pages never appear in AI responses. Instead, LLMs lean heavily on community-driven sources like Reddit, YouTube, Wikipedia, Yelp, and TripAdvisor, dramatically reshaping early-stage discovery. With LLM usage exceeding one billion monthly users, brands that do not participate in open forums risk disappearing from AI-mediated journeys. Marketers must treat GEO as a distinct discipline, not an extension of SEO.

Retailers faced a challenging year as economic factors, new technologies, and changing consumer behaviors reshaped the landscape. Here are our top five stories from this past year and what they meant to a tumultuous industry.

Artificial intelligence is working its way into every facet of the US economy, and the payments industry is no exception.

Walmart’s OnePay adopted Google’s Agent Payments Protocol (AP2) to drive agentic commerce as a credentialled provider, per a press release. With Chrome remaining consumer’s most popular browser, Gemini is narrowing the gap with ChatGPT as the most used chatbot: We forecast that by 2029, Gemini will hold 53% of genAI market share. That in turn could give Google’s AP2 a large share of agent-driven consumer spend in the long term, as consumers develop loyalty and use patterns around AI platforms.

On today’s EMARKETER Miniseries—AI-Driven Media Management—we explore how to break down the media manager role into workflows that can be automated or augmented by agentic AI, what agencies misunderstand about AI, and which agency tasks are ripest to hand off to AI right now. EMARKETER Senior Director of Content Jeremy Goldman speaks with Adam Epstein, co-founder and CEO of Gigi. Listen everywhere you find podcasts, and watch on YouTube and Spotify.

Over one-third of Gen Z (39%) and millennials (34%) who have used genAI tools to check symptoms report that they would put off seeing a doctor if the AI told them their issue was low-risk, according to an October 2025 poll from The Mesothelioma Center at Asbestos.com conducted by SurveyMonkey. Overrelying on AI for medical guidance carries real risk, especially as models are still maturing and sometimes produce faulty information. AI companies should add explicit in-chat disclaimers against being used as a replacement for medical care and strengthen guardrails to block unvetted or potentially harmful health advice.
