I Asked a 15-Year SEO Veteran How to Rank in ChatGPT | Dan Petrovic (DEJAN AI)
Want your brand to show up in ChatGPT, Claude, and Gemini? Here’s the uncomfortable truth: LLMs don’t crawl the web when they answer your questions. They search traditional indexes. ChatGPT leans on Bing. Gemini uses Google. Claude uses Brave. So if you’re not ranking in those indexes, you’re not even in the consideration pool. That single fact dismantles most of the “AEO” hype being sold for $99 PDFs right now. Dan Petrovic is one of the most respected (and delightfully nerdy) figures in SEO. He runs the Australian agency Dejan and was recently the top-rated speaker at Ahrefs Evolve in Singapore, where he presented research from asking Gemini a million questions to map how it ranks a million brands. In this episode, Dan explains exactly why your podcast or brand isn’t appearing in AI answers — and the practical steps to fix it. You’ll learn the difference between grounding, citations, and mentions (and why a linked mention is the holy grail), why Reddit gets rejected over 90% of the time, why there’s no such thing as “prompt volume,” and how Dan uses on-page optimization in an agentic loop to make Gemini “unable to resist” a client’s page.
