How to Rank in ChatGPT: Get Cited and Recommended

What You'll Learn

ChatGPT is the most widely used AI assistant, with over 200 million weekly active users. This guide covers:

• How ChatGPT finds and uses information
• OpenAI's crawlers: OAI-SearchBot and GPTBot
• Content strategies for ChatGPT citation
• Testing and monitoring your visibility

How ChatGPT Accesses Information

ChatGPT retrieves information through multiple channels:

1. Training Data

GPT models are trained on large datasets including:

• Web pages (filtered Common Crawl)
• Books and academic papers
• Code repositories
• Licensed content

Key insight: Content that was prominent on the web before the training cutoff may be embedded in the model's knowledge.

2. ChatGPT Search (all plans)

ChatGPT search looks up the web for current information:

• Retrieves and summarizes web pages
• Provides citations to sources

Key insight: Real-time retrieval means current content can be cited.

3. Plugins and Custom GPTs

Plugins and Custom GPTs bring data into a chat that doesn't come from the open web:

• A plugin, built on the Model Context Protocol, connects ChatGPT to a company's own service, such as a product catalog or a booking system. ChatGPT calls it when the user adds it to the chat or asks for it by name.
• A Custom GPT answers from the instructions and files its builder gave it, and searches the web only if the builder turned search on.
• Users can connect their own accounts, such as Google Drive or SharePoint, so answers draw on their private files.

Key insight: these answers come from data someone chose to connect. They reach people who already use your plugin or GPT. They don't decide whether ChatGPT names your brand to someone who has never heard of it; training data and ChatGPT Search do.

OpenAI's Crawlers: OAI-SearchBot and GPTBot

OpenAI runs separate crawlers for search and for training, and robots.txt controls each one on its own.

Robots.txt Configuration

Allow OAI-SearchBot on your public content. Add GPTBot too, unless you want to opt out of training:

User-agent: OAI-SearchBot
Allow: /
Disallow: /admin/
Disallow: /user/
Disallow: /private/

User-agent: GPTBot
Allow: /
Disallow: /admin/
Disallow: /user/
Disallow: /private/

Blocking GPTBot to protect your content from training does not remove you from ChatGPT search, as long as OAI-SearchBot stays allowed. OpenAI says a robots.txt change can take about 24 hours to reach its search systems.

Check Your Server Logs

Search your access logs for the OAI-SearchBot and GPTBot user agents to see which pages each one fetches. OpenAI publishes the IP ranges each crawler uses, so you can confirm a request really comes from OpenAI.

Content Strategies for ChatGPT

Strategy 1: Authoritative Definitions

Create definitive content that answers "What is X?" questions.

Example: If you're a CRM company, create comprehensive content answering "What is customer relationship management?"

Structure:

H1: What is [Topic]?
- Clear 1-2 sentence definition
- Expanded explanation
- Key components/features
- Benefits
- Examples
- Related concepts

Strategy 2: Comparison Content

ChatGPT frequently answers "X vs Y" questions.

Structure:

H1: [Product A] vs [Product B]: Complete Comparison
- Summary comparison table
- Feature-by-feature breakdown
- Use case recommendations
- Pricing comparison
- Verdict/recommendation

Strategy 3: "Best of" Lists

Position your product in curated recommendation lists.

Structure:

H1: Best [Category] Tools in 2025
- Introduction with selection criteria
- Ranked list with:
  - Product name and overview
  - Key features
  - Pros/cons
  - Pricing
  - Best for (use case)
- Comparison table
- How to choose guidance

Strategy 4: How-To Guides

Step-by-step content performs well for instructional queries.

Structure:

H1: How to [Achieve Goal] with [Your Product]
- Quick answer/overview
- Prerequisites
- Step-by-step instructions
- Tips and best practices
- Common mistakes to avoid
- FAQ section

Brand Mention Optimization

To increase brand mentions:

Build Topical Authority

Create comprehensive content clusters around your domain:

• Pillar pages for main topics
• Supporting content for subtopics
• Internal linking between related content

Establish Entity Recognition

Help AI associate your brand with your category:

• Consistent brand name usage
• Clear product/service descriptions
• Wikipedia presence (if notable)
• Industry directory listings

Generate Third-Party Mentions

Earn mentions on external sites:

• Guest posts on industry blogs
• Press coverage
• Review sites
• Industry publications

Testing Your ChatGPT Visibility

Manual Testing

Test relevant prompts directly:

1. Open ChatGPT
2. Ask variations of target queries:

- "What is [your product category]?"

- "Best [category] tools for [use case]"

- "How do I [problem your product solves]?"

- "[Your brand] review"

1. Document whether you're mentioned
2. Note the context (positive/neutral/negative)

Systematic Testing

Create a prompt library and test regularly:

• 20-50 prompts covering your key topics
• Test weekly or bi-weekly
• Track changes over time
• Compare with Browse on vs off

What to Track

• Mention rate: % of prompts mentioning your brand
• Position: Where you appear in lists
• Sentiment: Positive, neutral, or negative
• Accuracy: Is information correct?
• Citation: Does it link to you (Browse mode)?

Common ChatGPT Optimization Mistakes

Mistake 1: Blocking OAI-SearchBot

Check that robots.txt doesn't block OAI-SearchBot, either by name or through a catch-all User-agent: * rule. A common version of this mistake: a site blocks every AI crawler to keep its content out of training, and drops out of ChatGPT search with it.

Mistake 2: Thin Content

ChatGPT favors comprehensive, authoritative content. Thin pages rarely get cited.

Mistake 3: Outdated Information

If ChatGPT's training data has newer information than your site, you won't be the source cited.

Mistake 4: Missing Brand Context

Without clear product/service descriptions, ChatGPT can't accurately represent your offerings.

Advanced: Custom GPTs

A Custom GPT for your brand can help people who already know you, such as customers looking for support or prospects comparing your plans. Know its limits before building one:

• It reaches only people who look for it or follow your link to it.
• It doesn't change what ChatGPT says about you in ordinary chats. That still depends on training data and ChatGPT Search.
• You write its instructions and files, so keep them in line with your website or it will contradict it.

Uses that fit a Custom GPT:

• Product finder for your own catalog
• Support helper built on your help docs
• Calculator or tool for your industry

Measuring Success

Track these KPIs for ChatGPT optimization:

Next Steps

1. Verify OAI-SearchBot access in robots.txt, and decide separately whether to allow GPTBot
2. Create authoritative "What is" content for your category
3. Build comparison and "best of" content
4. Set up monthly testing cadence
5. Monitor and iterate
