The question was: now that AI tools like Gemini can autonomously navigate the web and retrieve information on a user’s behalf, will Google’s quality principles change? Mueller’s answer is clear: “I expect most principles will remain the same. A website that’s useful for users will generally also be useful for agentic browsers.”<\/strong>\r\n\r\n\r\n\r\n\r\n\r\nBut the critical addition: “Some details will undoubtedly evolve (and new basics, such as not blindly blocking agentic browsers, will come into play), but in the end, it’s still users.” So Google draws a line between content quality and technical accessibility: even if your site meets every quality standard, if you won’t let AI agents through the door, you’re shooting yourself in the foot.\r\n\r\n\r\n\r\n\r\n

What happened, exactly?<\/h2>\r\n\r\n\r\n\r\n\r\nThe SEO who asked the question hit a very real point: in Gemini 3.5 Flash, “computer use” is now a built-in feature. So the agent isn’t just reading text, it’s genuinely browsing the site like a user, clicking buttons, filling forms, completing tasks. In that case the subject of a “satisfying experience” changes: sometimes the one having that experience isn’t a human, it’s an information agent.\r\n\r\n\r\n\r\n\r\n\r\nMueller’s answer kept the core logic intact: a good site is a good site, whether a human or an agent looks at it. But with the “don’t blindly block” warning, he underlined a new technical reality. Because many sites block AI bots wholesale, to reduce server load or to protect their content. Mueller is saying that block can soon backfire on you.\r\n\r\n\r\n\r\n\r\n\r\nSearch Engine Journal explains it with an old example: years ago, when the nofollow tag came out, some sites blocked off their own About Us pages to funnel PageRank to “important” pages, and ended up hurting themselves. The agentic-browser situation may follow the same pattern: a technical decision made for one reason ends up with unintended SEO consequences.\r\n\r\n\r\n\r\n\r\n

What it means for SEO\/GEO<\/h2>\r\n\r\n\r\n\r\n\r\nThis completes the missing link in the chain we’ve been discussing for two weeks. Being visible, being recommended, being buyable, we kept assuming content and authority were what’s at stake. But Mueller steps back and asks: can the AI agent physically get into your site? If your robots.txt<\/a> or your firewall rejects agentic crawlers, neither your content quality nor your authority does anything. If the agent can’t get through the door, it can’t read you, understand you, recommend you to the user, and it certainly can’t act on your behalf.\r\n\r\n\r\n\r\n\r\n\r\nThere’s a fine balance here. On one side is the publisher logic we discussed last week with the beehiiv and Cloudflare example: “I’ll block the bot that takes my content and gives me no traffic in return.” On the other is Mueller’s warning: a blind block can make you invisible in AI’s eyes. So the blocking decision is now a strategic one that needs fine tuning; the wholesale “shut it all off” approach is becoming risky.\r\n\r\n\r\n\r\n\r\n

My take<\/h2>\r\n\r\n\r\n\r\n\r\nI took this comment seriously, because it puts a finger on a rarely-discussed but increasingly critical area: agent accessibility. For years, “technical SEO” meant Core Web Vitals, mobile usability, crawl budget<\/a>. Now a new layer of technical SEO is emerging: whether AI agents can reach your site and complete tasks on it. Call it “agent readiness.”\r\n\r\n\r\n\r\n\r\n\r\nLast week, discussing Amazon’s agent ads, I said “AI now buys on your behalf.” Mueller’s comment gives the technical foundation for that picture: for that purchase to happen, the agent has to get into your site, see the product, read the price, add it to the cart. A brand whose site blocks the agent isn’t at the table in the agentic-commerce era.\r\n\r\n\r\n\r\n\r\n\r\nMy real takeaway: the definition of SEO is expanding. We used to say “let Google’s bot into your site”; now we say “let the AI agent into your site too, and make its job easy.” An agent-friendly site is tomorrow’s ranking site.\r\n\r\n\r\n\r\n\r\n

Practical step<\/h2>\r\n\r\n\r\n\r\n\r\nThis week, open your robots.txt and your server\/CDN settings and ask: which AI crawlers am I blocking? Am I wholesale rejecting GPTBot, Google-Extended, ClaudeBot, PerplexityBot, and especially agentic crawlers? If so, reconsider that decision. Separate “the bot I don’t want to be visible to” from “the agent I need to be visible to.” Instead of blocking blindly, set a deliberate access policy. And make sure your site is browsable and actionable by an agent: clear buttons, open form fields, machine-readable product data.","protected":false},"excerpt":{"rendered":"
