Google is releasing Google-Agent: Here’s what you need to know

On March 20th, Google added Google-Agent to its user-activated download scripts.

The documentation update is straightforward: Google added the name of the user agent (Google-Agent), published the associated IP range, and noted that Google-Agent is used by agents hosted on Google’s infrastructure to navigate the web and take actions on behalf of users.

Google named Project Mariner as an example in the revised documents. Prototype Mariner is a research prototype that acts as an AI agent inside Chrome that can complete your tasks — access is currently limited.

Google has noted that Google-Agent will be released in the next few weeks.

How Google-Agent differs from other users

Google-Agent is different because it is activated by the user. It shows that a real person asked a Google AI agent to do something for them – and the agent went to your site to do it.

Most of the crawlers you see in your server logs are doing background processes like Googlebot crawling your pages.

Why is this important now?

The appearance of a Google agent in your log does not mean that AI agents are there completing purchases and filling out forms at scale today. The protocols, standards, and functionality that will enable that capability are still being developed.

What is something what happens is that agents start interacting with the web – browsing, checking, and navigating content on behalf of users. That behavior is real and growing. The surrounding infrastructure will be strong.

That is why now is the right time to pay attention.

What you have to do now

Start tracking Google-Agent activity

Filter your server logs to look for Google-Agent.

Just know that the volume will be low – the release only started on March 20. That’s okay. The foundation now is what gives you the context later.

Check your restrictions

A content delivery network (CDN) and web firewall (WAF) configuration designed to stop malicious bots can inadvertently block legitimate AI agents.

Semrush Enterprise AIO’s Agent Analytics provides a targeted view of how AI searchers can access your website and how they interact with content.

And if you’re a small to medium-sized business, Semrush’s Site Audit tool similarly shows whether AI search engines can effectively access your site.

Addressing any issues you see with AI crawlers’ ability to access your site now sets the stage for enabling AI agents later. Also, make sure that the Google-Agent IP range published in user-triggered-agents.json is allowed on your website.

The big picture: Mapping the future of the agent

Google indicates that we are moving towards a more active web of user agents.

Agentic search optimization (ASO) builds on the same foundation that SEO has always needed but adds the relevance of machines checking your product on someone else’s behalf.

Understanding where the web is headed – including emerging standards like WebMCP – is essential to staying ahead of that curve.
