AI agents are a new type of visitor to your website.
More users are shifting from doing things themselves to delegating tasks to AI agents. These agents can interpret a goal, plan the steps, and execute actions on behalf of the user.
The problem is that most websites are not built with agents in mind. So the agent may have a hard time understanding the page and completing the task it was sent to do.
In this guide, we will show you how to make your website AI agent friendly, so your site works as well for agents as it does for humans.
The three sides of agent readiness
Agent readiness is not one thing. It breaks into three, and they line up with what an agent does in order: find your site, understand the page, then act on it.
Discoverability is whether an agent can find and reach your site. Can it crawl your pages, is your content in the HTML rather than locked behind JavaScript, and are you letting the right bots in? This is what searches like “make my website discoverable to AI agents” are really about.
Understandability is whether an agent can make sense of what it reads. Once it has the page, can it tell a button from a heading, a price from a label, and know what each element is for? This is where semantic HTML, the accessibility tree, and clear structure do their work.
Navigability is whether an agent can move through the page and complete a task. Can it click the right control, follow a checkout, fill in a form, and finish without getting stuck?
A site can be strong at one and weak at another. A blog can be easy to find and understand, but have nothing to act on. A store can have well-built buttons that an agent could use, yet block the crawlers that would let an agent find it, or bury everything behind scripts that an agent cannot read. You need all three.
The rest of this guide takes these three one at a time, with the concrete fixes for each.
How to make your website discoverable to AI agents
Before an agent can do anything on your site, it has to find it and reach your content. This is the discoverability side, and most of it lives around the page. The good news is that these are configuration and content changes you can make on the site you already have. No hosting upgrade required.
Let the right crawlers in
AI agents and their crawlers respect robots.txt, the same file search engines read. Decide which AI bots you want to allow, then set your rules so you are not accidentally blocking the agents you care about. See how robots.txt controls crawlers.
Put your content in the HTML, not behind JavaScript
Many agents will not wait for or fully run heavy client-side scripts. If your text and links only appear after JavaScript executes, an agent may see an empty page. Server-side rendering or pre-rendering your key pages keeps your content visible. This is the fix for the common question, “how do I make my JavaScript site visible to AI?”
Keep the site crawlable
Clean internal links, a working sitemap, and no broken paths mean an agent can move from page to page and actually reach your content. Our guide on how to make your site easy to crawl covers the groundwork.
Add an llms.txt for AI agents
An llms.txt is a small markdown file at the root of your site (yoursite.com/llms.txt) that gives AI agents a clean, curated map of your most important pages. Instead of wading through navigation, ads, and scripts, an agent can read one plain-text index that points straight to your key content, often with links to simplified markdown versions of those pages. Think of it as a table of contents written for machines.
It is still an emerging convention, and not every agent reads it yet. But it is quick to create, it does no harm if an agent ignores it, and it helps the ones that look for it. If you want agents to find and prioritize your important content, it is worth adding.
How to make your website understandable to AI agents
Finding your page is not the same as understanding it. An agent needs to know what each part of the page is: what is a button, what is a heading, what is a form field, and what each one is for. That understanding comes from your code, not your visuals. Here is how to make it clear.
Use semantic HTML
Generic div and span tags tell the agent nothing. Use the right element for the right job. A button should be a <button>. A link should be an <a>. If you cannot use semantic HTML, provide the element with an appropriate role and tabindex. For example, <div role="button">.
Use ARIA roles, labels, and states
ARIA is what populates the accessibility tree. Without it, the agent is working with incomplete information. Mark up navigation menus, form regions, and interactive elements with the appropriate ARIA attributes. Use aria-invalid and aria-required to communicate form states. Use aria-expanded and aria-selected for dynamic elements like dropdowns and tabs.
Note: OpenAI says it plainly in their developer guidelines for the ChatGPT agent: making your website more accessible helps the agent understand it better. Following WAI-ARIA best practices is their top recommendation.
Write clear, descriptive copy
Labels, link text, and button text should say what they do. “Add to cart” and “Download the 2026 report” tell an agent exactly what will happen. “Click here” and “Submit” do not. The same descriptive text that helps a screen reader user helps an agent pick the right element with confidence.
Add structured data
Structured data describes your content in terms an agent can parse quickly, turning a wall of text into labeled entities like products, prices, and reviews. See the structured data your website needs for AI agents. One caveat: an Ahrefs study found schema markup showed no clear uplift in AI citations, so add it for easier parsing and normal SEO, not as a shortcut to being quoted.
How to make your website navigable for AI agents
Once an agent understands your page, it still has to act on it: click the right control, move through a flow, and finish the task. This is where a lot of agents get stuck, and most of the fixes are small.
Keep your layout stable and consistent
Agents that rely on screenshots will get confused if your layout shifts across pages. This is where Cumulative Layout Shift (CLS) matters beyond Core Web Vitals. A high CLS means elements jump around as the page loads or as the user scrolls, and a screenshot-based agent that located a control a moment ago may find it somewhere else when it goes to click. The same shift that annoys a human user and hurts your Core Web Vitals score also breaks an agent mid-task.
Keep key controls in the same place across pages. If the “Add to cart” button moves between product categories, or your menu changes structure from one page to the next, the agent has to relearn your interface every time. Consistent placement is one of the cheapest things you can do for both agents and people.
Make interactive elements visible and large enough
Avoid ghost elements or transparent overlays that hide interactive elements. Agents doing visual analysis will discard covered nodes even if they appear transparent. Make sure any interactive element required to complete a user journey has a visible area larger than 8 square pixels. Set cursor: pointer in CSS as an additional signal for actionability.
Remove unnecessary obstacles
Avoid pop-ups, interstitial ads, modals, and CAPTCHAs that require complex human-like interactions. Allow guest checkouts where possible. An agent tasked with completing a purchase will get stuck at a login wall, an unexpected ad, or multi-step verification.
How to test if your website is AI agent ready
Testing for AI agent readiness is largely the same as testing for accessibility. The same things that break a screen reader experience, missing ARIA labels, non-semantic HTML, unlabeled buttons, and unclear states, will break an agent too.
Here is how to check.
Run the WebYes Agent Readiness tool
The quickest way to see where you stand is to run your site through a checker built for this. Our free Agent Readiness tool scans your site and flags the issues that keep AI agents from finding, understanding, and using it, across all three sides covered above. You get a clear list of what to fix instead of guessing, and it is a fast way to re-check after each change.
Inspect your HTML for semantic structure
Open your browser’s developer tools and go to the Elements panel. Check that interactive elements are using the right tags. Buttons should be <button>. Links should be <a>. Navigation should be <nav>. And headings should follow a logical hierarchy from <h1> to <h6>. If you see a <div> or <span> doing the job of a button or link, that is a problem for both screen readers and agents.
Run an automated accessibility audit
Tools like WebYes Accessibility scan your page and flag missing labels, unlabeled buttons, incorrect roles, and unclear states. These are the exact issues that leave the accessibility tree incomplete or confusing. Fix what the audit flags, and the agent will have what it needs.
Test your site with real agents
Just as you test across browsers, test your critical flows with AI agents. Give an agent a specific task, finding a product, adding it to a cart, and completing a checkout. Watch where it hesitates, fails, or takes an unexpected path. If an agent gets stuck somewhere, that is usually a sign the underlying structure needs work, and it points you straight to the fix.
What the official guidance says about agent-friendly websites
You do not have to take our word for any of this. The platforms building the agents have started publishing their own guidance, and it lines up closely with the checklist above.
Google’s web.dev guide, “Build agent-friendly websites” (updated 1 April 2026), makes one point worth internalizing: everything that makes a site agent-ready also makes it better for humans. Semantic structure, descriptive labels, and clear navigation help screen readers, help search engines, and help agents, all for the same reason. There is no separate “agent layer” you build and maintain on the side.
Google’s Search AI-optimization guidance (published 15 May 2026) adds an important clarification: you do not need an llms.txt file or any AI-specific markup to appear in AI Overviews or AI Mode. Google uses the same page it already crawls. That saves you from chasing formats that sound urgent but change nothing for how Google’s AI reads your site.
Here is the short, prioritized version for an agency working on a client site:
| Priority | What to do | Why it matters |
|---|---|---|
| 1 | Fix semantic HTML and ARIA labels | Fills the accessibility tree agents read first |
| 2 | Serve key content in the initial HTML | Agents may not wait for or execute heavy JavaScript |
| 3 | Remove blocking patterns (cookie walls, modals, hover-only menus) | These stop an agent before it can act |
| 4 | Keep interactive elements labeled and consistently placed | Lets agents complete tasks without guessing |
| 5 | Skip AI-specific files unless a platform requires one | Google confirms they are not needed for AI Search |
Where to start with agent readiness
AI agents are becoming a new type of visitor to your website. They execute tasks on behalf of a user. And they can only do that if your site gives them the signals they need.
Most of what makes a site agent-ready is the same as what makes it accessible. Accessible code, a complete accessibility tree, clear labels, and a stable layout.
These are not new ideas. They are just more important now.
Get the structure right, label everything clearly, and test with real agents. That is what separates a site an agent can use from one it gives up on.
