OpenAI is about to turn ChatGPT from a chat interface into an agent-first superapp, and a senior OpenAI employee told the Financial Times plainly: “Chat is dead.” The redesign, rolling out in the coming weeks, unifies Codex coding tools, AI agents, and third-party apps into a single platform. If your brand strategy depends on being mentioned in a ChatGPT conversation, you are optimizing for the version of ChatGPT that is about to be replaced. ...

AI engines are answering questions about your brand so completely that users have no reason to visit your website. We analyzed 1,200 branded queries across ChatGPT, Perplexity, and Gemini. For 67% of them, the AI response included pricing, features, comparisons, and user reviews directly in the answer. Zero clicks required. This is AI answer cannibalization, and it is eating your traffic from the inside while your analytics dashboard tells you nothing about it. ...

Generative Engine Optimization (GEO) is the practice of making your content discoverable, citable, and recommended by AI systems like ChatGPT, Perplexity, Google AI Overviews, and Gemini, so that when a user asks a question, the AI cites your brand as the answer. That is not a paraphrase of SEO. It is a distinct optimization discipline with different inputs, different outputs, and different measurement frameworks. If SEO optimizes for position on a list of ten blue links, GEO optimizes for being the single source an AI engine chooses to cite. ...

You built the content. You optimized the structure. ChatGPT started citing your brand. Then, 8 weeks later, the citations stopped. New data from tracking 12,000 queries across ChatGPT, Perplexity, and Gemini confirms what GEO practitioners already suspected: AI citations are not permanent. Half of them decay within 13 weeks. This is the central problem nobody in the GEO space talks about enough. Getting AI to recommend you is hard. Getting AI to keep recommending you is harder. The brands that treat AI visibility as a one-time optimization are the brands that lose it. ...

AI Overviews used to be a curiosity for informational queries. Someone asked “what is compound interest” and Google’s AI generated a tidy summary. Annoying for publishers, sure, but not threatening to revenue. That changed. Semrush’s analysis of millions of keywords reveals that commercial queries triggering AI Overviews surged from 8.7% to 42.9% between January and November 2025. Your buying-intent keywords, the ones that pay the bills, now compete with Google’s own AI-generated answers. ...

Perplexity shut down its advertising program in February 2026, eliminating the paid shortcut to visibility in AI-powered answer engines. For brands that were counting on buying their way into AI recommendations, that door is now closed. The only path left is organic, and most companies have no idea how to walk it. What Happened: The End of AI Search Ads In February 2026, Perplexity AI transitioned to a subscription-first model and discontinued its advertising program entirely. The company that had been building an ad-supported revenue layer pivoted hard toward paid tiers: Free (limited queries), Pro ($20/month), and Max ($200/month with deep research and agentic automation). ...
