John Mueller of Google answered a question about whether Google’s search quality goals will change as AI agents continue to browse websites on behalf of users. Feedback may be more important to site owners than it first appears.
A Question About Agentic Browsers And Search Quality Standards
SEO asked Mueller at Bluesky if Google’s guidance on a satisfactory user experience, including principles regarding things like images and page design, could change as AI tools gain the ability to navigate and find information on websites automatically.
The question reflects a growing concern in the SEO community as tools like Google Gemini can browse websites, complete tasks, and return responses to users without the user actually visiting the page.
They asked:
“Hello John – Given that Computer usage is now a built-in tool for Gemini 3.5 Flash, and as the agent becomes a “thing”, would you expect principles such as “Images provide a satisfying experience” to evolve since the satisfying experience is an agent of knowledge? Curious about your thoughts.
Useful Websites for Common People Will Also Work for Agent Browsers
Mueller explained that most of Google’s existing quality standards will remain in place. A website that is useful for human users will often be useful for agent browsers.
He replied:
“I expect most goals will remain the same. A website that’s useful for users, will generally be useful for agent browsers.”
Mueller’s answer is that it’s a good idea to continue to make content useful to site visitors, which also means site positioning, navigation, and internal linking. AI agents do not change the fundamentals that Google’s algorithms still download from external user signals for measurement purposes, especially signals that indicate the site’s popularity with users.
Blindly Blocking Agentic Browsers Can Be An SEO Problem
Mueller’s response also contained a note that more information will emerge, and that site owners should avoid blindly blocking agent browsers.
He said:
“Other details will undoubtedly emerge (and new basics – such as … not blocking agent browsers … will work), but in the end, it’s still the users.”
Mueller’s response draws a line between content quality and technology accessibility. A site can meet Google’s quality standards and still create problems for itself if AI agents are blocked from accessing or interacting with its content.
In some ways this is similar to how nofollow links became a problem for some sites when they were introduced many years ago. Some site owners blocked important parts of their websites to drive more PageRank to pages they thought were important, giving zero priority to important parts of the website such as About Us pages.
The agent browser situation may follow a similar pattern, where technical decisions made for one reason end up having unintended SEO consequences.
Another way to think about it is that Google’s definition of a quality website is not being rewritten in the agent’s time. Existing standards were written for human users, and if AI agents work for human users, satisfying those agents is arguably the same task. What changes are the technical considerations of the AI agent, not the basic expectations of what a good website is.
