How ChatGPT picks sources
How to rank higher in ChatGPT: get cited
- Search: ChatGPT decides when to search the web. Per OpenAI, ChatGPT chooses whether to search the web based on what you ask, or you can click the web search icon to search manually.
- Sources: Answers carry links to sourcesOpenAI says ChatGPT search answers link to sources, and a Sources button opens them. A brand without a cited page has no visible reference. LLMReach tracks mentions and citations separately.
- Providers: Search runs through third-party providers. OpenAI says ChatGPT search leverages third-party search providers and content supplied directly by its partners. ChatGPT typically rewrites your question into one or more targeted queries first.
- Myth: OpenAI does not guarantee placementOpenAI says ChatGPT search connects people with original, high-quality web content. It promises no placement. If you opt out of OAI-SearchBot, your site will not appear in ChatGPT search answers.
ChatGPT writes one answer, not a list of links. In our October 2026 measurement of 249 buyer questions, only 13% of cited sites ranked in Google's top 10.

How to optimize for ChatGPT search: the steps
OpenAI documents what makes a site eligible. LLMReach builds on that with prompt mapping, answer-first content, technical AEO and citation tracking.
- Allow OAI-SearchBot in robots.txt. OpenAI says it is the crawler used to surface sites in ChatGPT search.
- Allow traffic from OpenAI's published searchbot IP addresses at your host or CDN, as OpenAI says eligibility requires.
- Know what blocking does. Sites opted out of OAI-SearchBot are not shown in ChatGPT search answers, though they can still appear as navigational links.
- Treat GPTBot separately. OpenAI says its rules are independent from OAI-SearchBot, so you can appear in search and opt out of training.
- Do not rely on ChatGPT-User for Search inclusion. OpenAI says it handles user-initiated visits and does not decide Search appearance. Set OAI-SearchBot rules in robots.txt instead.
- Allow about 24 hours after a robots.txt change for OpenAI's search systems to adjust.
- Write answer-first pages built for your agreed buyer prompts.
- Track citations with the exact prompt, platform and capture.
How it works
How to rank in ChatGPT: the Citation Stack
- 01
Prompt research
ChatGPT rewrites a question into targeted queries before searching, so we agree the fifty buyer prompts with you first. Your results are measured against those prompts, not against a ranking.

Technical optimization
Allow ChatGPT's search crawler, OAI-SearchBot, in robots.txt and at your host or CDN. We fix crawl access, schema and page signals so ChatGPT can retrieve your pages.
Explore Technical GEO - 03
Content
We write pages and answers built for your agreed prompts. ChatGPT weighs multiple factors and promises no fixed placement, so your content has to be worth citing.

Reddit authorityWe build genuine presence in the communities your buyers trust, with nothing automated. It adds authority around your brand but does not replace the technical and content work.

Visibility tracking
We track your citations on agreed prompts against a baseline set before work starts. You get weekly updates and a review every two weeks.

Who this is for
Built for brands where buyers ask AI first
Not for you
If any of these are you.
- You expect ChatGPT citations within a few weeks, but the engagement runs 90 days and measures citations against a baseline taken before work begins.
- We fix the structural reasons ChatGPT passes over your site: crawler access, schema and the signals that make a page retrievable when a model answers.
- You want a report to file away, not the technical and content work that gets your pages read by ChatGPT.
- You want a fixed ChatGPT ranking, but OpenAI states that no website is assured a placement in its results.
For you
If this is you.
- Your buyers ask ChatGPT questions before they contact sales, and you want your brand to be one of the sources it cites.
- You can name two or three competitors, so we can compare who ChatGPT cites for your buyers' prompts.
- You want your site fixed and your pages written so ChatGPT can reach and cite them, not another report.
- You're ready to commit to a 90-day window of prompt research, technical fixes, content and tracking for ChatGPT.
- This fits businesses whose buyers research with AI before contacting sales and that can act on a clear roadmap.
- Start with a free audit, reviewed live with you, no obligation.
FAQ
Questions about ChatGPT optimization
How to show up in ChatGPT results: how does ChatGPT choose which sources to cite?
ChatGPT rewrites your question into targeted queries, sends them to third-party search providers and partners, and ranks results with multiple factors. OpenAI says placement is not assured. Answers can then include citations and a Sources panel.
Which search engine does ChatGPT search optimization need to target for ChatGPT SEO services?
ChatGPT SEO services optimize for ChatGPT search, which OpenAI says leverages third-party search providers plus content supplied directly by its partners. Your site becomes eligible for inclusion when you allow OAI-SearchBot to crawl it and your host or CDN allows OpenAI's published searchbot IP addresses.
How do I show up in ChatGPT results?
Allow OAI-SearchBot to crawl your site and allow OpenAI's published IP ranges at your host or CDN. OpenAI states these are the steps that make a website eligible for inclusion. OpenAI recommends both to help ensure your site appears in search results.
Does blocking GPTBot remove my ChatGPT brand mentions from search?
Blocking GPTBot does not opt you out of ChatGPT search. OpenAI says the robots.txt settings for OAI-SearchBot and GPTBot are independent. You can allow OAI-SearchBot to appear in search results while disallowing GPTBot, which signals your content should not be used to train OpenAI's foundation models.
What happens to my ChatGPT visibility if I opt out of OAI-SearchBot?
ChatGPT visibility in search answers is lost if you opt out of OAI-SearchBot, according to OpenAI: opted-out sites are not shown in ChatGPT search answers. They can still appear as navigational links. After a robots.txt change, OpenAI says its systems can take about 24 hours to adjust.
How to rank on ChatGPT search: is it the same as Google ranking?
Ranking on ChatGPT search differs from Google ranking. Google lists ranked pages, while ChatGPT writes one answer with a few sources. In LLMReach's October 2026 test of 249 buyer questions, 13% of the sites the assistants cited ranked in Google's top 10 for the same question.
Can LLMReach promise my brand appears in ChatGPT?
LLMReach backs the engagement as a whole: a 30% increase in total citations across your site, measured against your own baseline, within 90 days. If that target is not reached, LLMReach keeps working at no extra charge until it is. No single answer is promised.
How do I know whether ChatGPT cites my brand?
LLMReach tracks mentions and citations for an agreed prompt set with its own AI visibility tracker. Each citation is captured with the exact prompt, platform and screenshot, so you can reproduce any test yourself. A baseline is taken before work begins.
Is the ChatGPT audit free?
The strategy session is free and carries no obligation. The audit and roadmap are delivered at no cost. You need your website URL and the names of two or three competitors.
