I think every SEO should be heavily paying attention to this. WebMCP lets agents use the functionality of your website in real time, natively.<\/p> <p>What does this look like?<\/p> <p>The obvious use case is an agent automatically filling out lead forms perfectly. But I think we will see much more interesting use cases as we publish our own agents. Let\u2019s say I\u2019ve made agents for SEO. <em>(I have! I just haven\u2019t shared them with others yet.)<\/em> I could share those with you via a SaaS model, perhaps \u2013 where you pay a monthly fee for access. Or, what I think will be most likely is that you will be able to have your agent access my agents via WebMCP. My agents will negotiate with your agents on pricing and possibly even help each other improve as well.<\/p> <h2>Search Is Turning Into AI Search<\/h2> <p>Google\u2019s Nick Fox recently stated, \u201cSearch is becoming AI Search, and the Gemini app is your personal assistant.\u201d He also said that Google is increasingly thinking of AI Mode and AI Overviews as one in the same.<\/p> <p>I keep looking back at this NYT article from three years ago.<\/p> <figure id=\"attachment_570593\" class=\"wp-caption aligncenter\" style=\"width: 870px\"><img decoding=\"async\" src=\"https:\/\/cdn.searchenginejournal.com\/wp-content\/uploads\/2026\/03\/google-search-changes-ai-rivals-headline.webp\" alt=\"Article headline about Google devising radical search changes to beat A.I. rivals, with highlighted text.\" width=\"870\" height=\"290\" class=\"size-full wp-image-570593\" srcset=\"https:\/\/cdn.searchenginejournal.com\/wp-content\/uploads\/2026\/03\/google-search-changes-ai-rivals-headline-384x128.webp 384w, https:\/\/cdn.searchenginejournal.com\/wp-content\/uploads\/2026\/03\/google-search-changes-ai-rivals-headline-425x142.webp 425w, https:\/\/cdn.searchenginejournal.com\/wp-content\/uploads\/2026\/03\/google-search-changes-ai-rivals-headline-480x160.webp 480w, https:\/\/cdn.searchenginejournal.com\/wp-content\/uploads\/2026\/03\/google-search-changes-ai-rivals-headline-680x227.webp 680w, https:\/\/cdn.searchenginejournal.com\/wp-content\/uploads\/2026\/03\/google-search-changes-ai-rivals-headline-768x256.webp 768w, https:\/\/cdn.searchenginejournal.com\/wp-content\/uploads\/2026\/03\/google-search-changes-ai-rivals-headline-850x283.webp 850w, https:\/\/cdn.searchenginejournal.com\/wp-content\/uploads\/2026\/03\/google-search-changes-ai-rivals-headline.webp 870w\" sizes=\"auto, (max-width: 870px) 100vw, 870px\" loading=\"lazy\" title=\"Why Google\u2019s New \u201cGoogle-Agent\u201d Is The Biggest Mindset Shift In SEO History via @sejournal, @marie_haynes\u63d2\u56fe2\" \/><figcaption class=\"wp-caption-text\">Image Credit: Marie Haynes<\/figcaption><\/figure> <p>They framed it as Google panicking over ChatGPT. There is no doubt in my mind, however, that Google had much bigger things in mind. The agentic web is not an afterthought! It has been in planning for many years now.<\/p> <p>I personally believe that from 1998 until now, those of us who create content have been giving it to Google to train AI. In return, we got human traffic and ad revenue. I think that partnership no longer exists in its traditional form.<\/p> <h2>Why This Is The Most Exciting Time To Be In SEO<\/h2> <p>This transition from a human-first web to an agent-first web might sound terrifying if you rely solely on traditional keyword rankings. In reality, it is the biggest opportunity we have seen since the invention of the search engine itself. WebMCP and UCP mean we are no longer just optimizing for clicks; we are optimizing for direct action, frictionless commerce, and automated lead generation. The creators who understand how these agents interact with backend systems are going to see a level of efficiency and reach that human browsing could never achieve. The partnership between creators and Google has definitively changed, but the future of what we can build on top of this agentic web is incredibly bright.<\/p> <h2>My Advice<\/h2> <p>It\u2019s hard to know how to act right now because no one, not even Google, knows exactly how the agentic web will unfold. Here\u2019s what I\u2019d recommend:<\/p> <ul> <li>Familiarize yourself with WebMCP and understand how it works.<\/li> <li>If you are ecommerce, learn all you can on UCP.<\/li> <li>Start learning to vibe code using tools like Claude Code, Google\u2019s AI Studio, or my favourite, Antigravity. (If you are a member of my paid community, I just published a full guide on using Antigravity in the Learning Hub.)<\/li> <li>Focus on the exciting things you can do with AI rather than letting media and social media steer you away! No one knows what\u2019s in store for the future, but I\u2019m positive that those who press in and learn how to use AI for good will have great success.<\/li> <\/ul> <p><strong>More Resources:<\/strong><\/p> <hr\/> <p data-pm-slice=\"1 1 [\" table=\"\"><em>Read Marie\u2019s newsletter, AI News You Can Use.
