ChatGPT SEO: How to get your website into ChatGPT's answers

ChatGPT names businesses it can clearly identify on the web and whose pages its crawlers are allowed to read. For search in ChatGPT, the OAI-SearchBot crawler reads your website. If your robots.txt blocks it, OpenAI says your site won’t appear in search answers. This article covers what to allow on the technical side and how to write content that ChatGPT links to as a source.

How ChatGPT finds its sources

ChatGPT answers from two sources:

• Trained knowledge: What the model read during training. The GPTBot crawler collects content for that. New knowledge only arrives with the next model.
• Search: For current or specific questions, ChatGPT searches the web and links the sources below its answer. OAI-SearchBot reads websites for that. ChatGPT also uses search results from third-party providers, so it’s worth adding your site to Bing Webmaster Tools too.

A third crawler, ChatGPT-User, only fetches a page when a user asks ChatGPT to open a link. It doesn’t decide whether you show up in search.

Step 1: Allow the crawlers in robots.txt

First, check whether your robots.txt blocks OpenAI’s crawlers. You’ll find it at yourdomain.com/robots.txt. This allows all three:

User-agent: OAI-SearchBot
Allow: /

User-agent: GPTBot
Allow: /

User-agent: ChatGPT-User
Allow: /

If your site sits behind Cloudflare, also check the settings for AI crawlers. Since July 2025, Cloudflare asks when you add a domain whether AI crawlers should be blocked. A block there applies even if your robots.txt allows everything.

Step 2: Serve your content as finished HTML

According to measurements Vercel published in 2024, OpenAI’s crawlers don’t run JavaScript. If your website only assembles its content in the browser, ChatGPT sees an empty page.

The test takes a minute: open your website, right-click and choose “View page source”. If your text is there, you’re fine. If you only see scripts and empty containers, your site needs server-side rendering or prebuilt pages. Astro, Webflow and WordPress all deliver finished HTML.

Step 3: Say clearly who you are and what you do

ChatGPT recommends businesses it can place with confidence. That takes a description that reads the same everywhere: on your homepage, in your Google Business Profile, on LinkedIn and in industry directories. One sentence with your service, your audience and your location is enough.

Structured data helps with that. With the Organization or Person schema, you state in a machine-readable way who’s behind the website. You’ll find examples to copy in the article on schema markup.

Step 4: Answer your customers’ questions directly

ChatGPT links to pages that answer a specific question. Here’s how to write for that:

• The question is the heading, phrased the way customers ask it.
• The first sentence below it answers it completely.
• Numbers, price ranges and comparisons are in the text, not only in images.
• At the end are the questions customers actually ask you in calls, with short answers.

Your emails and sales calls tell you which questions those are, along with Search Console and tools like DataForSEO that show search queries with search volume.

Step 5: Get mentioned on other sites

When someone asks for a recommendation, ChatGPT leans heavily on what others write about you. What counts are industry directories and vendor partner directories, comparison articles, review sites, trade articles and interviews. Every mention with the same description makes the match more certain.

How to measure whether ChatGPT mentions you

In Google Analytics or another tool, visits from ChatGPT show up with the source chatgpt.com. That number is small. According to a 2026 study by Graphite and Similarweb, visits from AI assistants make up less than one percent of website traffic. In the case of the automation platform n8n, only about 10 percent of the conversions that traced back to AI showed up as a visit from an AI source. The rest came later, directly or through a search for the company name.

Three things give you a better picture:

• Ask ChatGPT the ten questions your customers ask most every month, and note who gets named.
• Ask in your contact form how new customers found you.
• Use the free AI check to see whether AI crawlers are allowed to read your website and what they find there.
