Agent Web
Artificial intelligence has surpassed the limitations of web interfaces. What does this mean for everyone?
For the past 30 years, we have accessed information through buttons, links, and search bars. However, AI agents do not need any of those things. AI agents read hidden meanings, and as a result, everything changes.

big picture
When you visit a website, you see a designed interface consisting of buttons, images, and menus. However, when an AI agent visits the same site, it sees something entirely different: raw HTML, structured data, API endpoints, and metadata invisible to the human eye. Every website has always had a hidden layer of information that was not created specifically for the user. Now, AI agents read this hidden layer, act accordingly, and produce better results than any human clicking through the interface. This concept of accessing the “appearance” hidden behind the visual web represents the most significant change in how the Internet operates since the invention of the search engine.

8. From UX to AX — The Future of Dual Interfaces
1. The difference between what humans see and what AI sees
Visit any product page on Amazon. You will see photos, prices, reviews, and a buy button. This is the interface —the visual layer designed for the human eye and clicks.
However, beneath that interface lies another layer of information that is completely invisible. This includes structured data tags that tell the machine the exact product type, manufacturer, weight, and stock availability; JSON-LD schemas describing price fluctuations and stock levels; API endpoints used by mobile apps to retrieve the same data in various ways; and metadata that maps relationships with all other pages within the site.
For 30 years, this hidden layer was useful only to search engine crawlers and developers capable of reading source code. Ordinary users had to click, scroll, search, and wait through the interface.
The AI agent completely changed the situation.
Same website, two different realities
What you see
Product photo, $29.99 price, 4.5-star rating, customer reviews, “Add to Cart” button. Browse, compare, and decide. 10 minutes is all it takes.
What AI Sees
Schema.org product markup including exact SKU, GTIN, brand, and weight. JSON-LD pricing information including inventory status and currency codes from 12 warehouses. Aggregate score based on 2,847 ratings. API endpoint for real-time inventory checks. Related product graph linking 47 substitute products. Processing time of 2 seconds.
AI is not simply about automating button clicks on a website. AI accesses completely different information structures that have always existed but have never been built for users.
2. Explanation of the concept of “excuse”
In the fields of artificial intelligence and web engineering, a concept that perfectly explains these changes is gaining attention. It is ‘ Pretext ‘. Pretext refers to structured content that exists before becoming text and images displayed on a screen .
Consider a restaurant. As a guest, you see the exterior—the menu, the plates, and the decor. However, behind the kitchen door, a completely different system exists. There are supplier databases, ingredient inventories, preparation schedules, hygiene inspection records, and so on. While all this information influences your dining experience, you are never designed to interact directly with it.
An AI agent is entering through the kitchen door. It accesses the supplier database, reads the preparation schedule, and makes decisions based on information that would never be seen in a “restaurant.”
This isn’t hacking; this is how the web was originally designed.
Schema.org markup, JSON-LD, OpenAPI specifications, sitemaps, and llms.txt files are all tools that enable machines to interact with data . The Web has always consisted of two layers: a visual layer for humans and a structural layer for machines. However, until now, there have been no user tools smart enough to utilize the machine layer. Not until this very moment.
The reason the concept of ‘excuses’ is important is that it changes the perspective on what AI tools actually do. AI tools are not simply “searching faster.” They are reading a completely different version of the internet—much more structured, complete, and accurate—than what a visual interface can show.
3. 6 Hidden Layers That AI Agents Can Read
All modern websites contain up to 6 levels of machine-readable information that is not visible at all when visited in a browser.
Structured Data (Schema.org / JSON-LD)
Machine-readable tags embedded in HTML clearly display content such as product types, prices, reviews, business hours, recipe ingredients, and FAQ answers. Google requires these tags for rich search results. Content with proper schema markup is 2.5 times more likely to appear in AI-generated answers. AI agents read all content instantly without clicking.
APIs and Hidden Endpoints
Most modern websites fetch data from the same backend APIs that power mobile apps. These endpoints for search, filtering, pricing, and inventory management are accessible to AI agents. Research shows that API-based agents perform significantly better than browsing-based agents in complex data tasks because they completely bypass the interface.
Semantic HTML and Accessibility Tree
Well-coded websites use semantic elements ( <nav>, , ) and ARIA labels that describe not only the appearance but also the meaning of the content . AI agents read accessibility trees, which have the same structure as screen readers, to understand page layouts and interact with specific elements.<article><aside>
llms.txt — “robots.txt for AI”
New Standard: Markdown files located in the website’s root directory /llms.txt. These files provide AI models with a concise and professional summary of the site’s content. Written specifically for the Learning Leadership Model (LM), you can think of these files as AI-optimized “information about this website” guides. Agents can grasp the content in seconds. Major websites are already adopting this approach.
Markdown for Cloudflare Agent
Cloudflare has launched a system that automatically converts all HTML pages into clean Markdown when requested by AI agents. This is because inputting raw HTML into AI is like paying per word instead of reading every single character on a wrapper. While writing a simple heading in Markdown takes about three tokens, the same HTML heading consumes 12 to 15 tokens, even excluding the wrapper div and script tags. This leaves only the content layer on the web, allowing the AI to accurately obtain the information it needs.
WebMCP (Web Model Context Protocol)
This is the most important new standard. WebMCP, developed by Google and Microsoft under the leadership of the W3C Community Group, enables websites to specify functions in the form of structured tools, such as “how to search for flights” or “how to submit customer support tickets.” This allows websites to have defined schemas and security boundaries. Instead of AI agents guessing how a website works, the website directly tells the agent how to perform functions.
4. The actual tool to perform this task right now
This is not a theoretical discussion. These AI products are already bypassing web interfaces in ways that you can use today.
Chrome’s Claude
Anthropic’s browsing agent reads the page’s accessibility tree and DOM structure, not screenshots. When instructed to “find the cheapest option on this page,” it navigates the site’s underlying structure instead of visually scanning the layout. This is precisely why Anthropic’s browsing agent can fill out forms, click buttons, and extract data faster and more accurately than any human.
Gemini + Google Extension
Gemini completely bypasses the web interface and connects directly to Google’s backend services. Instead of navigating Google Flights directly, it queries underlying data; instead of opening Gmail, it calls APIs. For this reason, Gemini’s integrations work faster and more accurately because they bypass the visual interface entirely.
Perplexity and AI Search Engine
Perplexity reads hundreds of web pages, extracts structured content, and synthesizes direct answers along with quotes. Users do not need to interact with the website interface at all. By completely bypassing the web interface, you can obtain better results faster that are never achievable through web browsing.
ChatGPT Operators and In-depth Research
OpenAI’s Operator navigates actual websites to complete tasks such as making reservations, ordering food, and filling out forms. Deep Research systematically visits hundreds of web pages to extract structured information and generate reports. Both tools access web content to a depth impossible with manual navigation.
NotebookLM (Google)
NotebookLM generates AI experts based solely on web links you upload, extracting structured content, cross-referencing data across pages, and even providing podcast-style audio summaries. With NotebookLM, you can replace hours of reading and tab-switching with summarized insights in just minutes.
5. Why This Is Important When Using AI
When handling complex tasks, AI research is far more efficient than manual search. When comparing 15 products, analyzing competitor prices, or researching disease information, an AI agent that simultaneously reads the structural layers of 50 websites performs far better than a user clicking through them one by one. The information accessed by AI is often much more complete than what is displayed in a visual interface.
Enable connectors and extensions. Chrome’s Claude, Gemini extensions, and the ChatGPT plugin exist because they make AI much more useful by allowing direct interaction on the web. If you use AI only in “text-only” mode, you are missing out on its most powerful capabilities.
Artificial intelligence (AI) is shifting from ‘search’ to ‘execution. ‘ Today, ‘What is the best flight to Portland?’ → Text answer. Tomorrow, ‘Please book the cheapest flight to Portland for next Friday’ → Deal completed. Google CEO Sundar Pichai clearly described this as a transition from information search to execution.
The quality of AI responses depends on the quality of the source structure. AI provides accurate answers when fetching information from well-structured sites (clean Schema.org code, detailed metadata). However, if the source structure is poor, the reliability of the answer decreases. If AI provides a perfect answer for one topic but a poor one for another, the cause usually lies in the web structure.
6. Why This Is Important When Running a Website
The important point here is as follows: According to research by Imperva, AI agents currently account for over 51% of total internet traffic . In other words, more than half of website visitors are not human. Therefore, if a website is not designed for AI agents, it can become invisible to the majority of users on the web.
Adobe discovered that during the 2025 Black Friday period, AI-driven traffic had a 38% higher conversion rate than traditional search . The companies that AI agents can “recognize” are the very ones that become the targets of recommendations.
5 Action Items to Start This Week
1. Add JSON-LD structured data. You must include at least products, services, FAQs, company information, and reviews. Utilize Google’s Structured Data Markup Assistant or platform plugins. Sites using the correct schema are cited 2.5 times more by AI tools. This is the most impactful change.
2. Create an llms.txt file. Add a Markdown file to the site root that summarizes your business, key pages, and features in an LLM-optimized format. This takes about 30 minutes and will make your site immediately accessible from all major AI tools.
3. Organize semantic HTML. Use an appropriate heading hierarchy (h1→h2→h3), semantic elements (<p> <nav>, <main><div>, <article><div>), and descriptive ARIA labels. This provides two benefits as it helps both AI agents and accessibility.
4. Do not hide content. Do not hide important information in images, excessive JavaScript, or flows that require multiple clicks. Most AI crawlers do not execute JavaScript. Content not included in the HTML upon the first page load is perceived by the AI as not existing.
5. Consider making your API public. If you have product data, pricing information, or services, you can allow AI agents to directly utilize your business information through documented open API specifications. Shopify, Tripadvisor, and major e-commerce platforms have already adopted this approach, and these are the very platforms recommended by AI.
The new SEO is AI visibility.
Traditional SEO was optimized for Google’s “Top 10 Blue Links.” However, by 2026, Authorized Economic Operator (AEO) optimization will become crucial. Content must be made searchable and usable so that AI agents can make purchasing decisions and recommendations on behalf of users. If AI agents do not understand the structure of a website, they will lose their footing in AI-based search, shopping recommendations, and conversational commerce.
7. A New Standard Reshaping the Web
Three new standards are formalizing how artificial intelligence agents interact with the Web. These protocols will define the next era of the Internet.
WebMCP (Web Model Context Protocol)
W3C Standard • Google + Microsoft
It ensures that websites explicitly define their functions as structured tools equipped with defined schemas and security boundaries, such as “how to search for flights” or “how to make restaurant reservations.” Instead of AI agents blindly scanning the interface, the website encourages them to directly use specific functions . You can think of it as a sitemap for the AI era. Many companies are already implementing this.
llms.txt
Open Standard • Invented by Jeremy Howard
Inspired by robots.txt, this Markdown file /llms.txtis located in the site’s root directory and provides the Local Life Model (LM) with a concise and professional guide to the site. It tells the AI the site’s topics, most important pages, and how to utilize content, allowing the AI to obtain information immediately without needing to crawl the entire site. Some variations /llms-full.txtare configured to include the entire content, enabling the AI to fetch the content directly.
Markdown for Cloudflare Agent
Infrastructure Layer • Cloudflare CDN
It automatically converts all pages on your site into a clean Markdown format when requested by the AI agent. It removes ads, navigation bars, and scripts, leaving only pure content. x-markdown-tokensHeaders are included so the agent can know the context window cost before loading the page. If your site uses Cloudflare, you can enable this feature by changing settings with a single click to allow all AI systems immediate access to your content.
8. From UX to AX — The Future of Dual Interfaces
Leaders in the design field are already discussing a new field called AX (Agent Experience), which is the opposite concept of UX (User Experience) . While UX focuses on how humans interact with interfaces, AX focuses on how AI agents interact with the systems that support them.
The best websites of the future will feature a dual-interface architecture . One is a beautiful and intuitive visual layer for humans, and the other is a clean and well-documented structural layer for AI agents. Both layers access the same data and receive an optimized experience; they are simply built for different types of “users.”
This is exactly where WebMCP, llms.txt, structured data, and Markdown for Agents all converge. These technologies do not replace human web activity, but rather add another dimension that is just as important. This is because AI agents that cannot interact with websites ultimately lead to humans failing to discover your business.
Stack of Excuses — From the Invisible to the Actionable
Step 1: Structured Data (Schema.org) → AI knows what the content is.
Step 2: Semantic HTML + Accessibility → AI identifies how the page is structured .
Layer 3: llms.txt → AI knows what is most important on the site .
Step 4: Markdown for Agent → AI obtains clean content without interface noise .
Step 5: API/OpenAPI Specification → AI can perform tasks on the site .
Step 6: WebMCP → AI secures a complete toolkit equipped with authorization and security features .
conclusion
Web interfaces—namely buttons, menus, search bars, and scrolling—are designed for the human eye and hand. However, AI agents do not need these elements at all. AI agents read the structural layers that have always existed beneath them, process them at mechanical speeds, and increasingly take action on behalf of the user.
This does not replace the visual web, but adds a second layer. Just as a well-designed website provides an optimized experience for both visually impaired users and screen reader users, the web of the future will provide an optimized experience for both human browsers and AI agents.
If you use AI tools, enable extensions and connectors so that AI can access the structured web. If you run a website, start building machine-readable layers (structured data, llms.txt files, clean HTML) right now. Businesses that AI agents can “recognize” will thrive. Businesses that exist only as visual interfaces will remain invisible to more than half of all internet traffic.
