ChatGPT search launched on 31 October 2024, and if you run a website, you probably want to know one thing: can it send you traffic, and what do you need to do about it? The short answer is yes, it links to sources, and the main thing you control is whether OpenAI’s search crawler can reach your pages.
In this article I explain what ChatGPT search is, who can use it right now, how it shows sources, and the practical steps I’m taking on the sites I look after this week.
What Is ChatGPT Search?
ChatGPT search is a web search feature built into ChatGPT. Instead of answering only from what the model learned in training, ChatGPT can now look up fresh information on the web and give you an answer with links to the sources it used.
It grew out of SearchGPT, the prototype OpenAI tested with a small group of users from July. The big change now is that search is no longer a separate product. It lives inside the ChatGPT app that many people already use every day.
OpenAI says the search model is a fine-tuned version of GPT-4o. It was trained with synthetic data, including outputs from its o1-preview model.
How It Works for the User
There are two ways a search happens:
- Automatic: ChatGPT decides to search the web when your question needs fresh information, such as news, scores or prices.
- Manual: you click the web search icon in the message box to force a search.
The answer comes back as normal ChatGPT text, with small inline citations. A “Sources” button opens a sidebar that lists the pages ChatGPT used. You can then ask a follow-up question, and it keeps the context of the conversation.
That last point matters. On Google, each search mostly starts from zero. In ChatGPT, someone can ask five questions in a row and refine the answer each time, without ever typing a new search.
Who Can Use It Right Now
The rollout is staged:
- Plus and Team users have access from launch day, along with people who were on the SearchGPT waitlist.
- Enterprise and Edu users are due to get it in the next few weeks.
- Free users are due to get it over the coming months. OpenAI has not given an exact date.
It works on chatgpt.com and in the desktop and mobile apps. OpenAI also released a Chrome extension that makes ChatGPT search the default search engine in the browser’s address bar.
So today, the audience is paying users and early testers. That is a small slice of searchers. But the free rollout is what could make this matter for traffic, so I’d prepare now rather than wait.
What ChatGPT Search Shows: Sources, Links and Rich Results
For website owners, how the answer is laid out decides how many clicks you might get. Here is what I see in the first version.
Inline Citations and the Sources Sidebar
Most answers include short citations next to the sentences they support. These link straight to the source page. The Sources sidebar then lists every page used, with the site name and page title.
This is much more link-friendly than the old ChatGPT, which often gave answers with no sources at all. But the answer itself is still a summary. Many users will read it and stop. In my experience with any answer-style result, clicks go to people who want detail, want to buy, or don’t fully trust the summary.
Visual Results From Data Partners
For some topics, ChatGPT search shows visual blocks instead of plain text. OpenAI says it partnered with data providers for:
- Weather
- Stocks
- Sports
- News
- Maps
If your site lives on quick facts like a score, a forecast or a share price, expect very few clicks from ChatGPT search. Those answers are complete on the screen. This is the same pattern we have seen with Google’s own answer boxes for years.
News Publisher Partners
OpenAI has content deals with a number of large news publishers, and it says it worked with them while building the product. It also says partners get no special ranking boost, and that any website or publisher can choose to appear in ChatGPT search.
I take that at face value for now. But I’d still expect big, trusted news brands to show up often for news questions, because that is where reliable fresh content lives.
How ChatGPT Search Finds Your Pages
This is the most useful part for site owners. OpenAI says ChatGPT search uses third-party search providers plus content supplied directly by its partners. It also runs its own crawler for search.
OpenAI uses three different user agents (the names a bot uses to identify itself to your server). Each does a different job, and each can be controlled in robots.txt (a small text file that tells bots which parts of your site they may visit).
| User agent | What it does | If you block it |
|---|---|---|
OAI-SearchBot |
Finds and surfaces pages in ChatGPT search | Your pages are not shown in ChatGPT search answers |
GPTBot |
Collects content that may be used to train OpenAI’s models | Your content should not be used for model training |
ChatGPT-User |
Visits a page when a ChatGPT user or custom GPT asks it to | Not used for search eligibility; it acts on behalf of a user |
OpenAI explains the details on its overview of OpenAI crawlers page. The key point: these settings are independent. You can block training and still allow search.
The Mistake I Expect to See Most
When ChatGPT first got popular, many site owners added a block for GPTBot. Some went further and blocked every OpenAI agent, or every AI bot they could find on a list. I wrote about that early reaction in what ChatGPT’s launch could mean for search and content.
Blocking GPTBot alone does not keep you out of ChatGPT search. But blocking OAI-SearchBot does. I usually see broad “block all AI bots” rules added by a plugin, a CDN setting or a developer in a hurry. Those rules may now be costing you visibility in a new search product without anyone noticing.
Example robots.txt Setups
If you want to appear in ChatGPT search but don’t want your content used for training, this is the setup I’d use:
User-agent: OAI-SearchBot
Allow: /
User-agent: GPTBot
Disallow: /If you are happy with both, you don’t need to add anything. Bots are allowed by default unless a rule says otherwise. If you want to stay out of ChatGPT search completely, disallow OAI-SearchBot instead.
One more thing to check: some firewalls and bot-protection tools block crawlers at the server level, before robots.txt even matters. Your robots.txt can say “allow” while your CDN quietly returns an error. I always check both.
Does Ranking in Google Still Matter for ChatGPT Search?
Yes. OpenAI has not published ranking factors, and I won’t pretend to know them. But since it relies on third-party search providers, pages that are already easy to find, crawl and understand in regular search engines start with an advantage.
Because of Microsoft’s long partnership with OpenAI, I’d make sure your site is in good shape in Bing, not just Google. That means verifying it in Bing Webmaster Tools, submitting your sitemap and checking for crawl errors there. Many SEOs ignore Bing because its share is small. I think that is a mistake now. I covered Bing’s own AI chat in the new Bing with AI chat, and the same basics apply.
The usual SEO basics still do the heavy lifting:
- Pages that load fast and return a clean 200 status code.
- Clear titles and headings that match what the page is about.
- Content that answers questions directly near the top.
- Correct canonical tags (a line of code that tells search engines which version of a page is the main one).
- No important content hidden behind logins or heavy scripts.
What ChatGPT Search Means for Your Traffic
Let me be honest about the numbers: right now, ChatGPT search traffic will be tiny for most sites. Only paying users have it. Google still handles the vast majority of searches.
But the direction is clear. Google is spreading AI answers too, with AI Overviews now in more than 100 countries. Searchers are getting used to reading an answer first and clicking second. ChatGPT search pushes that habit further.
Who Is Likely to Lose Clicks
- Sites built on simple facts: definitions, dates, conversions, scores, weather.
- Thin “answer” pages that repeat what is available everywhere.
- News sites that rely on headline traffic for breaking stories, unless they are cited often.
Who Is Likely to Gain
- Sites with original information: first-hand testing, unique data, expert experience.
- Brands people already trust and name in their questions.
- Pages that serve the next step after the answer: buying, booking, signing up, comparing.
My view: citations reward pages that add something. If ChatGPT can summarise your page fully in two lines, the user has no reason to click. If your page has the detail, the tool or the offer, the citation becomes a doorway.
How to Prepare Your Site for ChatGPT Search
Here is the process I’m following on the sites I manage. None of it is complicated, and most of it takes less than an hour.
- Check your robots.txt. Open yoursite.com/robots.txt and look for rules that mention OAI-SearchBot, GPTBot, ChatGPT-User or a wildcard
User-agent: *with a broadDisallow. Make sure OAI-SearchBot is allowed if you want to appear. - Check your firewall and CDN. Look at your bot protection settings. If AI crawlers are blocked by default, decide on purpose which ones you allow.
- Look at your server logs. Search for “OAI-SearchBot” in your access logs. If it is visiting and getting 200 responses, you are reachable. If you see 403 or 429 errors, something is blocking it.
- Set up Bing Webmaster Tools. Verify your site, submit your XML sitemap and fix any crawl issues it reports.
- Search for your brand and key topics in ChatGPT. If you have a Plus account, try the questions your customers ask. Note which sites get cited and how the answer is framed.
- Watch referral traffic. In GA4, check the referral report for chatgpt.com as a source. Add a note in your reporting for 31 October so you can compare before and after.
- Improve the pages that should be cited. Put a clear, direct answer near the top, then add the depth, examples and data that make a click worth it.
What I’d Skip for Now
I’d skip any service selling “ChatGPT search ranking” packages. The product is days old. Nobody outside OpenAI knows how it ranks sources yet.
I’d also skip rewriting your whole site for AI. Clear, helpful, well-structured pages already work for search engines and for AI answers. The fixes above are about access and basics, not a new set of tricks.
Should You Block ChatGPT Search?
For most businesses, I’d say no. Being cited in an answer is a form of visibility, and blocking OAI-SearchBot just hands that spot to a competitor.
There are fair reasons to block, though:
- Your business model depends on page views, and you believe summaries will replace visits rather than create them.
- You have licensing or legal concerns about how your content is shown.
- You are negotiating your own content deal and want to control access.
If you are unsure, I’d allow OAI-SearchBot, block GPTBot if training worries you, and review the decision once free users have access and you can see real referral numbers.
How ChatGPT Search Compares to Google’s AI Answers
It’s natural to compare this with Google’s AI Overviews. Both give a written answer with links. But there are real differences in how people use them.
- Starting point: Google shows the AI answer above normal results. ChatGPT shows the answer as the whole result, with sources in a sidebar.
- Conversation: ChatGPT is built for follow-up questions. Google is still mostly one query at a time.
- Audience: Google reaches almost everyone who searches. ChatGPT search, for now, reaches paying users and testers.
- Control: For ChatGPT search, you manage access with a dedicated crawler. For Google, AI Overviews draw on the normal Googlebot crawl.
In practice, I don’t treat these as separate strategies. A page that is crawlable, clear and genuinely useful has the best chance in both.
Conclusion: Your Next Step With ChatGPT Search
ChatGPT search is now live for paying users, with free users to follow. It cites and links to sources, and whether your pages can appear depends mainly on letting OAI-SearchBot crawl your site.
My advice is simple: check your robots.txt and firewall today, set up Bing Webmaster Tools if you haven’t, and start tracking chatgpt.com referrals. Then keep building pages that give people a reason to click. If you want the background on how we got here, my earlier write-up on the SearchGPT prototype is a good place to start.
