Google I/O was Tuesday. There's a lot to sort through — and most of it isn't the hardware story. It's the search story. This week, Cassie breaks down the I/O announcements that actually matter for visibility strategy, unpacks the llms.txt drama that played out in a LinkedIn comment section yesterday, and covers Perplexity updates that got buried under all of it.

In this episode:

• Google I/O: the Search box redesign, AI Mode at 1 billion users, Search agents, and Universal Cart
• Why Search agents change what "being discoverable" actually means
• Google's GEO guide said stop using llms.txt — then Lily Ray pointed out Google uses it on their own docs. John Mueller's response draws a distinction the guide never made.
• Why GEO isn't just an SEO conversation — it's the infrastructure that makes agentic commerce work
• Bing on trust as infrastructure in AI-powered search
• Perplexity: GPT-5.5 as the new default in Computer, Teams integration, and Personal Computer at $20/month

Google is building toward a world where your website is the backend. This episode is about what that means for your strategy right now.
