What agentic search is, how AI agents and AI browsers research, compare and act for users, and how to make your website ready for them.

Quick answer: Agentic search is when an AI agent does the searching and acting for a user: it researches options, compares them, fills in forms and can complete tasks such as bookings or purchases. Examples include ChatGPT’s agent mode, AI browsers like ChatGPT Atlas and Perplexity Comet, and agentic features in Google AI Mode. To prepare, make your site fast, accessible and clearly structured, publish complete facts in text, keep forms simple and use accurate structured data.
Classic search returns links for a person to click. Answer engines return an answer for a person to read. Agents go one step further: they take the next action. For businesses, that means your website is increasingly read and operated by software on behalf of a buyer.
Key takeaways
- Agents research, compare and act, not just answer.
- Agents favour sites that are easy to read and operate.
- Clear prices, availability and policies in text are essential.
- Accessible, standard HTML forms work best for agents.
- AEO and agent readiness share the same foundations.
What can AI agents do today?
| Task | What the agent does |
|---|---|
| Research | Reads many pages and builds a shortlist with reasons |
| Compare | Extracts prices, features and policies into a comparison |
| Book | Checks availability and fills in booking forms |
| Buy | Adds items to cart or completes checkout where supported |
| Contact | Fills enquiry forms or drafts messages |
OpenAI also introduced an Agentic Commerce Protocol with Stripe in 2025 to let merchants accept purchases from AI agents, and Chrome’s Lighthouse added an agentic browsing audit in 2026, a sign that agent readiness is becoming a measurable web standard.
How do you make your website agent-ready?
- Put key facts in text. Prices, plans, availability, delivery areas, hours and policies, not only in images or PDFs.
- Use clear, semantic HTML. Proper headings, labelled buttons and form fields with clear labels.
- Keep forms simple. Fewer steps, standard inputs, clear error messages.
- Add structured data. Product, Offer, LocalBusiness, Service and FAQ markup that matches the page. See schema markup for AEO.
- Allow the right crawlers and user agents. Review bot protection so legitimate AI assistants are not blocked by accident.
- Be fast and stable. Agents work through pages step by step; slow or shifting layouts break them.
- Offer an llms.txt for documentation-heavy sites. See what llms.txt is.
How does agentic search affect AEO?
Agents still start with search: they need to find and trust your brand before they act. That means the AEO foundations, answer-first content, consistent facts and third-party mentions, decide whether your business is on the agent’s shortlist at all. Agent readiness then decides whether the agent can complete the task with you.
Which businesses should prepare first?
- Ecommerce and D2C brands. See AEO for ecommerce.
- Travel, hospitality and restaurants with online booking
- Clinics, salons and services with appointment systems
- SaaS with self-serve sign-up and public pricing

Frequently asked questions
What is the difference between AI search and agentic search?
AI search gives an answer. Agentic search uses that information to take an action, such as booking or buying, on the user’s behalf.
Can AI agents buy from my online store?
Some can, where the platform and store support it, such as checkout features in ChatGPT for participating merchants. Most agents today research and prepare the purchase for the user to confirm.
Should I block AI agents?
Most businesses benefit from allowing legitimate assistants, since they act for real customers. Block abusive scrapers at the CDN while keeping known assistants allowed.
Is agentic search relevant to B2B?
Yes. Agents increasingly research vendors, compile comparison tables and draft enquiries, which rewards clear pricing and capability pages.
