ChatGPT SEO is the work of making your website a source that ChatGPT finds, cites and recommends when it searches the web. In practice that means three things: letting OpenAI's search crawler reach your pages, ranking for the many searches ChatGPT runs behind each prompt, and publishing specific pages that answer those searches better than anyone else.
Key takeaways
- ChatGPT search doesn't show sites that block its search crawler, OAI-SearchBot, in its answers, so crawl access comes first.
- ChatGPT rewrites a prompt into one or more search queries, so you get cited by ranking for the sub-questions, not just the head keyword.
- In controlled tests, rewriting tricks such as adding statistics or quotes mostly failed; moving a page higher among the sources the model reads worked far better.
- Brand mentions across the web correlate with AI visibility far more strongly than link authority does.
- Measure how often ChatGPT cites you across repeated checks, not a "rank in ChatGPT", because answers change from run to run.
What is ChatGPT SEO?
ChatGPT SEO (also called SEO for ChatGPT or ChatGPT search optimization) is optimizing your site so that ChatGPT uses it as a source and links to it in answers. It is one part of generative engine optimization (GEO), the broader practice of earning visibility in AI-generated answers from ChatGPT, Gemini, Perplexity and Google's AI features.
The phrase has a second meaning that you will see in many search results: using ChatGPT as a tool to do SEO work, such as drafting outlines or meta descriptions. This guide is about the first meaning, how to get cited by ChatGPT, and covers the second one briefly near the end. If you're sorting out the vocabulary (GEO, AEO, LLM SEO), our comparison of GEO vs SEO vs AEO explains where the terms overlap and where they differ.
Two ways ChatGPT can mention your brand
ChatGPT can talk about your brand from two different places, and each one responds to different work.
Model knowledge (training) | ChatGPT search (live web) | |
|---|---|---|
Where the answer comes from | What the model learned before its training cut-off | Pages fetched from the web for this prompt |
Does it link to you? | Usually not | Yes, through citations and the Sources panel |
OpenAI crawler involved | GPTBot | OAI-SearchBot, plus ChatGPT-User for user-triggered fetches |
How fast your changes can show up | Only after a future model is trained | As soon as your page is crawled and retrieved |
What you can influence | How widely and consistently your brand is described across the web | Crawl access, rankings for the queries ChatGPT runs, page quality |
Most of the levers you control sit in the right-hand column, and search answers are where citations and clicks come from, so the rest of this guide focuses on them.
How does ChatGPT search choose which sources to cite?
ChatGPT search turns a prompt into web searches, reads the results and cites the pages it used. OpenAI's help page on searching the web with ChatGPT describes the process in plain terms:
- ChatGPT search "sometimes partners with other search providers" and "typically rewrites your query into one or more targeted queries" that it sends to them. After reviewing the first results, it may send more specific follow-up queries. The page points to Microsoft's and Shopify's privacy policies for those providers.
- It uses an approximate location based on the user's IP address, and if memory is on, saved memories can shape how it rewrites the query.
- Answers that used search can include citations, and a Sources button lists the cited sources and other relevant links.
- On ranking, OpenAI says ChatGPT "ranks search results using multiple factors intended to help users find relevant, reliable information. Placement is not guaranteed."
So a prompt is not a keyword: one question becomes several searches, each with its own results. And the sources ChatGPT sees depend on who is asking and from where, which is why two people can get different citations for the same question.
Why ranking for the head keyword is not enough
ChatGPT's citations overlap only loosely with the top 10 results for the original prompt. In an Ahrefs study of 15,000 prompts (data collected in July 2025), only 8.0% of ChatGPT's in-text citations ranked in Google's top 10 for the same prompt, and 8.1% in Bing's top 10. Ahrefs attributes the gap to "query fan-out": AI assistants retrieve pages for several variations of the query, not just the query itself.
That doesn't mean rankings don't matter. It means the rankings that matter are for the variations: the comparison, the "for small teams" version, the pricing question, the how-to. A site on page one for ten specific sub-questions has more chances to be retrieved than a site at position 7 for one broad term.
What the research says works, and what doesn't
Much of the popular "how to rank in ChatGPT" advice traces back to one paper. The GEO paper (Aggarwal et al., KDD 2024) reported that rewriting methods such as adding quotations or statistics could "boost visibility by up to 40%" in generative engine responses. Those tests placed each page in a fixed set of sources the model already had in front of it; they didn't test whether a page gets found in the first place.
A later peer-reviewed re-test, C-SEO Bench (NeurIPS 2025 Datasets and Benchmarks), ran these methods across several domains and found that "most current C-SEO methods are not only largely ineffective but also frequently have a negative impact on document ranking." Strategies that move a page higher among the sources the model reads, which the authors call traditional SEO, were "significantly more effective". The authors also found that gains shrink as more sites adopt the same tricks.
Off-site reputation shows up strongly in observational data. Ahrefs' study of 75,000 brands (December 2025) found that branded web mentions correlated with AI visibility at 0.66 to 0.71 across ChatGPT, AI Mode and AI Overviews, and YouTube mentions at about 0.737. For ChatGPT, Domain Rating correlated at only 0.266. As Ahrefs notes, correlation isn't causation, but the direction is consistent: being talked about matters more than raw link metrics.
Tactic | What the evidence says | Verdict |
|---|---|---|
Allow OAI-SearchBot | OpenAI: sites that block it are not shown in ChatGPT search answers | Required |
Rank for the sub-queries ChatGPT runs | C-SEO Bench: a higher position among the sources beats rewriting; Ahrefs: citations come from query variations | Highest impact |
Earn brand mentions, including on YouTube | Ahrefs: strongest correlations with AI visibility (correlation only) | High impact, slow |
Add statistics, quotes and citations to "optimize for AI" | GEO: up to 40% in a fixed set of sources; C-SEO Bench: mostly ineffective | Do it for readers, not as a lever |
Publish an llms.txt file | Ahrefs: 97% of llms.txt files it studied got zero requests in May 2026 | Optional, low priority |
Keyword stuffing | No evidence it helps; search engines' spam policies apply | Avoid |
Step 1: Let OpenAI's crawlers reach your site
ChatGPT search won't show your pages in its answers if you block its search crawler. OpenAI documents its crawlers on its bots page, and each one is controlled separately in robots.txt: "Each setting is independent of the others."
Bot | What it does | If you block it |
|---|---|---|
OAI-SearchBot | Surfaces websites in ChatGPT's search features | Your pages are not shown in ChatGPT search answers, though they can still appear as navigational links |
GPTBot | Collects content that may be used to train OpenAI's foundation models | Your content should not be used for training; search answers are controlled by OAI-SearchBot, not GPTBot |
ChatGPT-User | Fetches pages for certain user actions in ChatGPT and Custom GPTs | robots.txt rules "may not apply", because a user started the action |
OpenAI recommends allowing OAI-SearchBot. A robots.txt that keeps ChatGPT search open while opting out of model training looks like this:
User-agent: OAI-SearchBot
Allow: /
User-agent: GPTBot
Disallow: /Whether to allow GPTBot is a business decision. Blocking it does not remove you from ChatGPT search, but it does mean future models learn about your brand mainly from what other sites say. Three more checks matter as much as robots.txt:
- Your CDN or firewall. OpenAI's help page asks site owners to confirm that their host or CDN allows traffic from OpenAI's published search bot IP addresses. Bot-protection rules often block crawlers without telling you.
- Server-rendered content. When Vercel analysed AI crawler traffic in December 2024, none of the major AI crawlers, OpenAI's included, rendered JavaScript. Crawler behaviour changes over time, but the safe rule holds: put your text, tables and prices in the HTML your server sends, not only in content loaded by scripts.
- Patience after changes. OpenAI says it can take about 24 hours after a robots.txt update for its search systems to adjust.
Step 2: Map the searches ChatGPT will run for your topic
Your target is the set of searches behind the prompt, not the prompt itself. Start from a prompt a real buyer would type, then list the sub-questions ChatGPT would need to answer it well.
For a prompt like "What's the best accounting software for a five-person design studio?", the fan-out could include:
- best accounting software for small agencies
- [product A] vs [product B] for freelancers
- accounting software with project billing
- [product] pricing per user
- how to invoice clients by project
Find them in Google's People Also Ask boxes and related searches, the headings of pages that already rank, sales and support questions, and ChatGPT itself: run the prompt with search on and read which pages it cites.
Don't optimize for one exact wording. In SparkToro's January 2026 research, volunteers wrote 142 prompts for the same need (choosing headphones for a family member who travels), and the prompts had an average semantic similarity of just 0.081. Yet the AI tools still returned a fairly consistent set of brands across those prompts. ChatGPT responds to the intent, so cover the intent and its sub-questions thoroughly instead of chasing a phrase.
Step 3: Rank in the results ChatGPT pulls from
Classic SEO is the core of ChatGPT SEO, because ChatGPT search works from search results. In concrete terms:
- Be indexed in both Google and Bing. OpenAI's ChatGPT search help page links Microsoft's privacy statement among the search providers it sends queries to, and the Ahrefs top-10 overlap figures were almost identical for Google and Bing. Verify your site in Bing Webmaster Tools as well as Google Search Console, and submit your sitemap to both.
- Give each sub-question a clear home. A page, or a clearly headed section, per sub-question, with the question's wording in the heading, is easier to retrieve than one long page that mentions everything in passing.
- Match the intent of each query. A "vs" query wants a comparison table; a pricing query wants current prices and what each plan includes; a how-to query wants numbered steps.
- Link the cluster together. Link sub-question pages to the main guide and to each other with descriptive anchors.
- Track positions for the sub-questions, not only the head term. If you watch only one keyword, you won't see the ranking gains that lead to citations.
Google's AI features follow the same logic; our guide to ranking in Google AI Overviews covers the Google-specific version.
Step 4: Write pages that are easy to cite
A page gets cited when a passage on it answers the searched question directly and can be trusted on its own. C-SEO Bench warns against cosmetic rewrites, not good writing, so focus on what helps a reader verify and reuse your answer:
- Answer first. Open each section with a one- or two-sentence answer, then the detail. A short summary at the top of the page helps readers and makes the main answer easy to find.
- Make sections stand alone. Use the full noun ("ChatGPT search", "the Pro plan") at the start of a section instead of "it" or "this", so a passage still makes sense when quoted on its own.
- Be specific. Prices with dates, limits, steps, named examples. Vague claims such as "affordable" or "powerful" give an engine nothing to cite.
- Use tables for comparisons and specs. A table with plan names, prices and limits answers several sub-questions at once.
- Add something only you have. Your own data, a worked example, a test you ran. If your page says what ten other pages say, an engine has no reason to prefer it.
- Show dates and authorship. OpenAI's help page tells users to check when a cited source was published or updated; visible dates and a named author make your page easier to trust.
- Keep the prose plain. Write the way an expert explains something to a colleague: short sentences, one idea per paragraph, no keyword repetition.
Step 5: Build brand mentions beyond your own site
If the Ahrefs correlations are a guide, some of the most important ChatGPT SEO work happens off your site. Brands that are discussed on other websites and on YouTube are the ones AI assistants tend to surface. Ways to earn that kind of mention:
- Get included in "best [category]" roundups and comparison articles that already rank for your sub-queries; those pages are exactly what ChatGPT retrieves.
- Publish original data that journalists and bloggers can quote and link to.
- Make, or appear in, YouTube videos for your category's how-to and comparison queries.
- Keep review-site and directory profiles current, and show up where buyers ask questions: communities, podcasts, partner webinars.
This is slow work with no guarantee, but it would help your brand even without AI search.
Step 6: Keep facts consistent everywhere
ChatGPT assembles answers from several sources, so conflicting information about you produces confused answers. Use the same product names, prices and descriptions on your site, profiles, directory listings and partner pages. When a price or plan limit changes, update every page that states it, change the visible "updated" date, and ask third-party publishers to correct old figures.
Step 7: If you sell products, share a product feed
Shopping answers in ChatGPT work differently from regular citations. OpenAI's help page on shopping with ChatGPT search says product results "are selected independently by ChatGPT and are not ads", and that ChatGPT considers structured metadata such as price and product description from first- and third-party providers. Merchants can apply to share a product feed through OpenAI's merchant program, which OpenAI says helps products surface with more accurate information.
ChatGPT now shows ads too: OpenAI began testing them in the US on February 9, 2026, for users on the Free and Go plans. OpenAI says ads do not influence ChatGPT's answers and are clearly labelled, so buying ads is not a way to get cited.
Step 8: Measure whether ChatGPT cites you
You can't improve what you don't check, and checking ChatGPT has a catch: its answers vary from run to run. In the same SparkToro research, volunteers ran 12 prompts through ChatGPT, Claude and Google's AI a combined 2,961 times. There was a less than 1 in 100 chance that ChatGPT or Google's AI would give the same list of brands in any two responses. The author's conclusion: visibility measured as a percentage across many runs is a reasonable metric, while a "ranking position in AI" is not.
A workable routine:
- Pick 10 to 30 prompts and keywords that matter commercially, including ones that don't contain your brand name.
- Run each one with search on, in a logged-out or clean session, from the country you care about, so memory and personalization don't skew the result.
- Record the cited source URLs, not only whether your brand name appears in the text.
- Repeat on a schedule (weekly is a sensible rhythm) and compare the share of checks that cite you.
Referral traffic is a second signal, but don't rely on it alone. ChatGPT has tagged links with utm_source=chatgpt.com, yet on October 14, 2026, Search Engine Roundtable reported, citing an analysis by Adobe's Cedric Huesler, that links opened from GPT-6 answers were arriving without the tag or a referrer, so analytics tools filed the visits as direct traffic. OpenAI had not confirmed the change in that report, so compare your own ChatGPT and direct traffic before and after early October 2026. Your server logs help too: requests from OAI-SearchBot and ChatGPT-User show that OpenAI is fetching your pages, though not that it cites them.
The full method, including how to calculate citation share, is in our guide to AI search visibility tracking.
How to do this in RankTera
RankTera runs this check for you. Once a week, it asks ChatGPT (OpenAI) and Gemini to search the web for each keyword you track and records whether your domain is among the sources they cite, shown as Mentioned or Not mentioned next to the keyword's Google position. Open a keyword's details to see up to 10 cited source URLs per engine, with your page highlighted. It's included for every tracked keyword on every Rank plan, with no add-on.
Worked example: getting a SaaS site cited for a buying prompt
The numbers below are an illustrative example, not client data.
A company sells time-tracking software for agencies. Its target prompt is "What's the best time tracking software for a small agency?" Its category page ranks at position 14 in Google for "time tracking software for agencies", and in 10 checks of the prompt in ChatGPT with search on, the site was cited once.
The team maps five sub-queries, checks where it ranks for each, and works through them over eight weeks:
Sub-query | Google position before | Work done | Google position in week 8 |
|---|---|---|---|
time tracking software for agencies | 14 | Rewrote the category page around agency use cases | 9 |
[brand] vs [competitor] | Not in top 50 | New comparison page with a feature and price table | 4 |
time tracking with client billing | 22 | New step-by-step setup guide | 8 |
time tracking software pricing per user | 31 | Pricing page with a plan table and dated prices | 6 |
how to track billable hours in an agency | Not in top 50 | New how-to article | 12 |
The team also pitched two "best time tracking tools" roundups that ChatGPT had cited in the first checks, and one of them added the product.
In week 8, the same prompt checked 10 times cited the site in 4 runs: twice through the comparison page, once through the pricing page and once through the billing guide. The roundup that added the product was cited in 6 of the 10 runs. Three lessons come out of this:
- The pages that got cited were the sub-question pages, not the category page the team first wanted to push.
- The off-site roundup carried the brand into answers even when none of its own pages was cited.
- A single check would have shown 0 or 1 citations and told the team almost nothing; 10 checks showed a clear change from 1 in 10 to 4 in 10.
What we found: what the top "ChatGPT SEO" pages cover
The Google results for "chatgpt seo" are split between two intents. In our SERP analysis on October 15, 2026, five of the six top-ranking pages we analysed taught how to use ChatGPT as an SEO tool, and only one, Rank Math's, was about getting a brand mentioned by ChatGPT. Their median length was 3,222 words; three of the six had an FAQ section and none used a table. Google also showed an AI Overview for the query.
A separate run of "chatgpt seo" through RankTera's KW Research (US Google results, October 15, 2026) analysed five top-ranking pages: forgeandsmith.com, semrush.com, apiarydigital.com, claneo.com and wordstream.com. They averaged 1,841 words, and RankTera extracted 74 keywords from the text under their headings. The most used were "search engines" (4 times per page on average) and "keyword research" (3), followed by a group at 2 each that includes "ChatGPT SEO", "SEO for ChatGPT", "foundational SEO" and "SEO strategy". "Foundational SEO" showing up among the top terms fits the research above, which points to classic SEO as the base of ChatGPT visibility rather than a separate discipline.
Using ChatGPT for SEO work (the other meaning)
ChatGPT is also a useful SEO assistant if you check its output: good at language tasks, weak at anything that needs live data.
Task | How ChatGPT helps | What to verify |
|---|---|---|
Keyword research and sub-questions | Brainstorms variations, questions and related topics | Search volumes: use Google Keyword Planner or Search Console, not ChatGPT's estimates |
Outlines and content briefs | Drafts a heading structure from your notes | That it matches what actually ranks for the query |
Titles and meta descriptions | Writes several options to the length you set | Accuracy, length and the primary keyword |
Structured data | Drafts JSON-LD for an article or product | Validate it with Google's Rich Results Test |
Facts, statistics, current rankings | Often wrong or out of date | Always check the primary source |
On AI-written content, Google's February 2023 guidance still sets the rule: its ranking systems reward high-quality content "however it is produced", but using automation, including AI, "with the primary purpose of manipulating ranking in search results" violates its spam policies. AI-assisted drafts that a person edits, fact-checks and improves are fine; mass-produced pages are not.
Frequently asked questions
How do I rank higher in ChatGPT search results?
ChatGPT has no fixed rankings, so aim to be cited more often. Allow OAI-SearchBot in robots.txt and in your CDN, rank in Google and Bing for the specific sub-questions behind your target prompts, and answer each one clearly on your site. Then earn mentions on the sites ChatGPT already cites for your topic, and measure your citation rate across repeated checks.
Can you pay to appear in ChatGPT answers?
No. OpenAI says ads in ChatGPT run on separate systems, are clearly labelled and do not influence its answers, and that shopping results are selected independently and are not ads. OpenAI also says placement in search results is not guaranteed. The way in is organic: crawlable pages that rank for the queries ChatGPT runs and a brand that other sites talk about.
Does ChatGPT use Google or Bing?
OpenAI's help page lists Microsoft, not Google, among ChatGPT's search providers: it says ChatGPT search partners with third-party search providers and links Microsoft's and Shopify's privacy policies for them. OpenAI also runs its own search crawler, OAI-SearchBot. In Ahrefs' 2025 data, ChatGPT's citations overlapped with Google's and Bing's top 10 at almost the same rate, about 8%, so make sure you are indexed and ranking in both.
How long does it take to show up in ChatGPT?
After you unblock OAI-SearchBot, OpenAI says its systems take about 24 hours to adjust to a robots.txt change. Getting cited usually takes longer, because your pages still have to be crawled and rank for the queries ChatGPT runs. Expect a timeline similar to SEO: weeks for new pages on an established site, months for a brand-new domain.
Does Google penalize AI-written content?
Not for being AI-written. Google's guidance says its systems reward high-quality content however it is produced. What Google acts against is using automation, including AI, mainly to manipulate rankings, such as publishing many low-value pages at scale. Edit AI drafts, check every fact, add your own examples and data, and publish only pages that help a reader.
What is AI SEO called now?
The most common names are generative engine optimization (GEO), answer engine optimization (AEO) and LLM SEO. They all describe earning visibility in AI-generated answers, and ChatGPT SEO is the ChatGPT-specific part of that work. The fundamentals overlap heavily with classic SEO: crawlable pages, rankings for the right queries and content worth citing.
Track your Google rankings and ChatGPT citations in one table
ChatGPT SEO comes down to two things you can watch: where you rank for the queries ChatGPT searches, and how often ChatGPT cites you. You can do all of it yourself, and RankTera keeps both in one table: your Google position for every keyword (daily or weekly, depending on plan) plus a weekly ChatGPT and Gemini citation check. Start your 14-day free tier — no card needed: it includes Rank Starter with 300 keywords checked weekly, and nothing is charged when it ends. You can also compare RankTera's plans and pricing.
