I was lucky enough to be in the room at Google Marketing Live when they announced some of the biggest changes to search in over 25 years, and it's quietly rewiring how every business gets found online. While everyone's feed is overcomplicating AEO, GEO, and LLMs.txt files, Google's own VP of ads got on stage and laid out exactly what it takes to show up in AI search in three plain rules. When I first checked my own numbers, my site health was 90%+ but my AI visibility score was under 20 out of 100 - and that gap is the whole problem.
Walking through Google's three rules (unique content, helpful content, and being agent-ready), why great SEO and AI visibility are one strategy and not two, and exactly how I track both in one place with Semrush One. Showing you brand citations across ChatGPT, Perplexity, Gemini, and Google AI Mode, the site audit for agent readiness, and prompt research so you can see where your brand actually shows up, then fix it.
