ChatGPT SEO is how a founder gets a product named when a buyer asks ChatGPT for a tool like it. According to Pew Research Center, 34% of US adults had used ChatGPT by early 2025, about double the share in 2023. ZeroCrew wrote this guide for founders who want their product to be one of the few names in that answer.
Answers are starting to replace clicks. Pew Research Center found that Google users clicked a regular result in 8% of visits when an AI summary appeared, against 15% of visits without one, in browsing data from March 2025. ZeroCrew reads that as a clear signal for founders: being named inside the answer now matters as much as ranking below it.
The good news for a founder with zero employees is that ChatGPT SEO can favor clear facts and honest mentions over a big budget. Researchers behind the GEO study, published at KDD 2024, found that lower-ranked sites gained the most from citing sources and adding statistics. This ZeroCrew guide walks through each step and names the tools in the ZeroCrew directory that do it.
What is ChatGPT SEO, and how is it different from Google SEO?
ChatGPT SEO, also called generative engine optimization (GEO) or answer engine optimization (AEO), is the practice of making your product easy for ChatGPT to find, trust, and quote. ZeroCrew treats ChatGPT SEO as classic SEO with one new goal: being named inside the AI answer, not only listed as a link below it.
Google SEO and ChatGPT SEO share a base: a site crawlers can read, pages that answer real questions, and a good reputation on other sites. The difference is the output. Google shows a list of links, while ChatGPT writes one answer and cites a handful of sources. ZeroCrew's SEO and content tools page lists tools that serve both, because founders need both.
How does ChatGPT decide which products to recommend?
ChatGPT recommends products from two places: what the model learned in training, and what ChatGPT search reads on the web when it looks something up. OpenAI does not publish a ranking formula, so ZeroCrew bases this guide on OpenAI's own crawler documentation and on research into how AI answers pick their sources.
The research points to four things a founder controls, and ZeroCrew turns each one into a section below:
- Access. OpenAI's search crawler can read your pages.
- Clarity. Each page answers one question with facts, numbers, and sources.
- Reputation. Trusted sites in your niche mention your product.
- Measurement. You test the prompts your buyers type and track what changes.
How do you let ChatGPT search find your site?
ChatGPT search finds your site through OAI-SearchBot, OpenAI's search crawler. OpenAI's crawler documentation says sites that opt out of OAI-SearchBot will not be shown in ChatGPT search answers, though they can still appear as navigational links. ZeroCrew puts this check first because a blocked crawler cancels every other step in this guide.
OAI-SearchBot and GPTBot are separate controls. OpenAI's documentation says disallowing GPTBot signals that a site's content should not be used to train its models, and that each crawler setting is independent of the others. ZeroCrew points out what that means for a founder: you can keep your pages out of training and still let ChatGPT search read and recommend them.
ZeroCrew suggests running the access check in this order:
- Open the robots.txt file at the root of your domain and look for a rule that blocks OAI-SearchBot, or blocks all bots.
- Check the bot and firewall settings of any service in front of your site, such as Cloudflare or Vercel, so AI crawlers are not turned away there.
- Make sure your pricing, features, and docs pages load as plain text, with no login wall.
- Give it a day. OpenAI's documentation says a robots.txt change can take about 24 hours for its systems to adjust.
ZeroCrew lists two kinds of site builders for founders who are starting fresh. Pick Framer for a no-code site with SEO and AEO settings built in, or Lovable if you would rather build the site and app from a chat prompt. ZeroCrew's design and sites page ranks the rest of the options.
What kind of page does ChatGPT quote?
Adding citations, statistics, and quotations made pages more visible in AI answers, according to the GEO study by Aggarwal and colleagues, published at KDD 2024. Those three methods raised a page's visibility by 30% to 40% on the authors' main visibility measure. ZeroCrew writes its own guides this way, with a sourced, dated fact in most sections.
Keyword stuffing did not help in the GEO study's tests. The GEO study found that stuffing keywords offered little to no improvement, and on Perplexity it did about 10% worse than the unchanged page on one of the study's visibility measures. ZeroCrew's advice follows from that result: write for the question your buyer asks, and use the keyword where it reads naturally.
Smaller sites gained the most in the GEO study, published at KDD 2024. Adding citations raised visibility by 115% for sources that ranked fifth in search results, while top-ranked sources lost visibility on average. ZeroCrew sees that finding as good news for a founder with a new site and few backlinks: clear, sourced writing can compete with older pages.
ZeroCrew's checklist for a page ChatGPT can quote:
- One question per page, asked in the heading the way buyers type it.
- The answer in the first 40 to 60 words, so it reads well on its own.
- Every number with its source and date.
- A table when you compare your product with others.
- Prices with the month you checked them.
- Plain words on who the product is for, and who it is not for.
ZeroCrew ranks the tools for this work on its SEO and content tools page. To find the questions buyers ask, use Ahrefs for full keyword and competitor research, or Keywords Everywhere if you would rather pay with credits for only the data you pull. To write the pages, SEObot runs your blog as an agent, while Jasper keeps every draft in your brand voice.
| Tool | What it does for ChatGPT SEO | Pick it when |
|---|---|---|
| Ahrefs | Keyword, backlink, and competitor research, plus Brand Radar for AI mentions | You want one research suite |
| Keywords Everywhere | Search volume, CPC, related keywords, and trends, paid with credits | You want low-cost keyword data |
| SEObot | Researches keywords, writes, and publishes blog articles | You want an agent to run the blog |
| Jasper | Writes marketing content, including GEO content, in your brand voice | You write a lot and want one voice |
If you want one agent to do this work every day, IntentCraft is ZeroCrew's own product, so weigh that when you compare it. IntentCraft researches what buyers search for and ask AI about, then writes and publishes those pages every day. It requests indexing through Search Console, IndexNow, sitemaps, and llms.txt, fixes titles, internal links, and outdated facts, and checks how ChatGPT, Perplexity, Gemini, and Claude answer about your space. It sends a weekly report, and its MCP server lets you drive it from Claude, ChatGPT, or Cursor.
Why do mentions on other sites matter so much?
Mentions on trusted third-party sites matter because AI search leans on them. A 2025 University of Toronto study by Chen and colleagues found that AI search shows a strong, systematic bias toward earned media, meaning third-party authoritative sources, over brand-owned and social content, while Google was more balanced. ZeroCrew reads that as the step with the most weight for a small founder.
The University of Toronto study by Chen and colleagues also describes a big brand bias that favors well-known companies, and it suggests ways for niche players to compete. ZeroCrew's take on that finding: a small product does best when it is the clear answer to one narrow question, and when the sites that cover that niche say so.
ZeroCrew suggests earning mentions in these places:
- Directories in your category, including a free listing on ZeroCrew.
- Comparison articles, where you offer the writer accurate facts and prices.
- Communities where buyers ask for tools. Pew Research Center found Wikipedia, YouTube, and Reddit were the most common sources in Google's AI summaries for searches made in March 2025, though the University of Toronto study found ChatGPT cites social sites far less.
- Your own social posts, which help writers and editors find you, so they can cover your product on the third-party pages AI search trusts.
ZeroCrew lists tools for each of those jobs on its marketing page. For social posts, Typefully fits founders who post mostly on X and LinkedIn, while Buffer covers more networks, including Google Business Profile, and has a free plan as of November 2026.
How do you know if ChatGPT recommends your product?
You know ChatGPT recommends your product when you ask it the questions your buyers ask and your name appears, and when visits arrive tagged from ChatGPT. OpenAI says ChatGPT adds utm_source=chatgpt.com to the links it sends from search. ZeroCrew suggests tracking both signals every month, because AI answers change.
ZeroCrew suggests this monthly test:
- Write ten prompts your buyers would type, such as "best tool for" your job, your category plus "alternatives", and "how do I" plus the problem you solve.
- Run each prompt in ChatGPT, then compare the answers in Perplexity and Claude, since each assistant picks its sources in its own way.
- Log whether your product is named, which sources the answer cites, and which other products appear.
- Filter your analytics for utm_source=chatgpt.com in PostHog or Mixpanel.
- Put the cited sources on your list of places to earn a mention.
ZeroCrew ranks the analytics options, including PostHog and Mixpanel, on its product analytics page. Pick PostHog for analytics, session replays, and feature flags in one open-source tool that starts free, or Mixpanel for event analytics built around funnels and retention. For automated tracking, Ahrefs' ZeroCrew page lists Brand Radar, which tracks how often AI assistants mention your brand.
How does ZeroCrew help your product show up in ChatGPT?
ZeroCrew helps in two ways: ZeroCrew gives your product a third-party page AI assistants can cite, and ZeroCrew ranks the tools that do the rest of the ChatGPT SEO work. ZeroCrew's developers page says a free listing gets its own page, a link back to your site, and a chance to be cited when people ask AI for tools like yours.
A ZeroCrew listing can be read by AI agents as well as people. The public MCP server on ZeroCrew's MCP page lets an agent in Claude, Cursor, or ChatGPT search the directory by job and read a tool's page. That means a founder's agent looking for a tool like yours can find your ZeroCrew page and quote what it says.
For ChatGPT SEO work, ZeroCrew's SEO and content tools page ranks Ahrefs, Jasper, Keywords Everywhere, and SEObot two ways as of November 2026: by search demand and by what founders say is worth the price. ZeroCrew's AI assistants page covers ChatGPT, Perplexity, and Claude, the assistants you test your prompts in each month.
Founders who would rather have the agents set up for them can use ZeroCrew's AI agent setup. ZeroCrew picks the agents for each job, connects them to the tools you already use, and keeps them up to date as new models come out, starting at $1,000 a month as of November 2026, after a free discovery call.
