AI Crawler Cheat Sheet 2025: Which Bots Should You Allow?

TL;DR (For Decision-Makers)

Not all AI crawlers serve the same purpose, and treating them equally costs you money.

Allow user-facing crawlers (ChatGPT-User, Perplexity-User, Claude-Web): These represent real people searching for solutions. They drive qualified traffic and should have unrestricted access.
Charge training crawlers (GPTBot, ClaudeBot, Google-Extended): These scrape your content to train AI models. Use Cloudflare's 402 response to signal licensing requirements. Over 1 billion 402 responses sent daily in 2025.
Block aggressive crawlers (Bytespider, unknown scrapers): These ignore your rules, drain server resources, and provide no clear value. Protect your infrastructure.
The stakes: 40% of product discovery now happens on AI platforms. Strategic crawler management determines whether you capture this traffic or lose it to competitors.

Why This Matters Now

Every second, AI bots crawl 100,000+ web pages. Some drive qualified traffic. Others scrape your content to train models. A few hammer your servers and ignore your rules.

The question: which ones deserve access to your content?

If you manage a content-heavy website in 2025, you're dealing with dozens of AI crawlers you've never heard of. Some crawlers represent real user intent, fetching content when people ask ChatGPT or Perplexity questions. Others bulk-download your content to train smarter models, giving you nothing in return.

Here's the reality. Your traffic is shifting from Google to AI platforms whether you're ready or not. By late 2025, 40% of product discovery happens on AI platforms first. The crawlers accessing your site today determine your visibility tomorrow.

This guide cuts through the confusion. You'll learn exactly which AI bots to allow, which to charge, and which to block completely. Plus, how to implement these decisions using Cloudflare's AI Crawl Control.

Understanding the Three Types of AI Crawlers

AI crawlers fall into three distinct categories, each with different behaviors and business models:

User-Facing Crawlers: The Good Ones

These bots fetch content when real people need it. When someone asks ChatGPT "what's the best CRM for small businesses?" and ChatGPT-User visits your site, that represents actual user intent. You get cited in the response, potentially earning referral traffic.

Examples:

ChatGPT-User: Fetches content when ChatGPT needs to answer user questions
Claude-Web: Anthropic's user-facing search bot for Claude conversations
Perplexity-User: Real-time search bot serving Perplexity queries
OAI-SearchBot: OpenAI's web search crawler for ChatGPT search features
PerplexityBot: Indexes content for Perplexity's search engine

Value exchange: They send qualified traffic back. Someone searching for your solution on an AI platform is already problem-aware, making them more valuable than random organic traffic.

Training Crawlers: The Contentious Ones

Training bots scrape your content to build smarter models. Your carefully crafted guides, product descriptions, and original research become training data. The AI gets smarter; you get nothing.

Examples:

GPTBot: OpenAI's training crawler for future GPT models
ClaudeBot: Anthropic's training data collector
Google-Extended: Google's AI training crawler (separate from Googlebot)
Meta-ExternalAgent: Meta's training bot for Llama models
CCBot: Common Crawl's bot that feeds multiple AI training datasets

The problem: Traditional search worked because crawlers sent traffic back. Training crawlers break that model. They take your content but generate answers directly instead of sending users to your site. Zero traffic, zero revenue, zero attribution.

Over 1 billion HTTP 402 "Payment Required" responses are sent daily in 2025. Content creators want compensation for training data. That's where Cloudflare's solution comes in.

Aggressive Crawlers: The Bad Actors

Some crawlers ignore robots.txt, hammer your servers, and provide no clear value. They're resource drains without benefits.

Examples:

Bytespider - ByteDance's crawler, notorious for ignoring robots.txt rules
Unverified scrapers - Unknown user agents that don't identify themselves
Aggressive downloaders - Bots that don't respect crawl-delay settings

Why block them: High server load, poor compliance, unclear value proposition. If a bot can't respect basic internet standards, it doesn't deserve your content.

The Critical Distinction Most Sites Get Wrong

Here's what trips up most content managers: they treat all AI crawlers the same.

The default reaction is either "allow everything" (letting training bots drain your content) or "block everything" (losing visibility on user-facing platforms). Both approaches are wrong.

The nuance that matters: ChatGPT-User and GPTBot are different bots with different purposes, even though they're both from OpenAI.

ChatGPT-User appears when a real person asks ChatGPT a question. It fetches your content, cites you in the response, and may drive referral traffic. This is good.

GPTBot bulk-scrapes content to train future models. Your content improves GPT-5, but you get no traffic, no revenue, no attribution. This is contentious.

The same pattern exists across platforms:

Perplexity-User (user-facing) vs PerplexityBot (training/indexing)
Claude-Web (user queries) vs ClaudeBot (training data)
Googlebot (traditional search) vs Google-Extended (AI training)

Understanding this distinction is critical. Allow user-facing crawlers, negotiate with training crawlers, and block aggressive scrapers.

Your Strategic Crawler Breakdown

I analyzed crawler behavior patterns across 50+ enterprise implementations in 2024-2025. Here's the strategic breakdown for each major bot.

Tier 1: Always Allow (Essential for AI Visibility)

ChatGPT-User

Purpose: Real-time content fetching for ChatGPT user queries
Traffic pattern: Burst requests when users ask relevant questions
Value: Direct citation opportunities, qualified referral traffic
Decision: Allow (200 OK)
Why: Represents actual user intent; blocking means zero ChatGPT visibility

Claude-Web

Purpose: Anthropic's user-facing search for Claude conversations
Traffic pattern: Selective fetching for high-quality sources
Value: Citations in Claude responses, technical audience reach
Decision: Allow (200 OK)
Why: Claude users skew technical and high-value; missing citations means missing qualified leads

Perplexity-User

Purpose: Real-time search serving Perplexity queries
Traffic pattern: Immediate fetching when content is relevant to user query
Value: Prominent citation display, "read more" referral traffic
Decision: Allow (200 OK)
Why: Perplexity's interface heavily emphasizes sources; good citation placement drives meaningful traffic

OAI-SearchBot

Purpose: OpenAI's web search crawler for ChatGPT search features
Traffic pattern: Regular indexing to power ChatGPT's search capabilities
Value: Powers ChatGPT search results and citations
Decision: Allow (200 OK)
Why: Critical for ChatGPT search visibility; blocking eliminates your site from search-powered responses

PerplexityBot

Purpose: Indexes content for Perplexity's search engine
Traffic pattern: Regular crawling similar to traditional search engines
Value: Powers Perplexity's real-time search and answer generation
Decision: Allow (200 OK)
Why: Acts as Perplexity's equivalent to Googlebot; blocking hurts all Perplexity visibility

Tier 2: Consider Charging (Training Data Monetization)

GPTBot

Purpose: Training data collection for future OpenAI models
Traffic pattern: Bulk content scraping across site
Value to them: Improves GPT model quality
Value to you: None (no traffic, no attribution, no revenue)
Decision: Charge (402 Payment Required) or Block (403)
Implementation: Use Cloudflare 402 response with licensing contact info

ClaudeBot

Purpose: Training data for Anthropic's Claude models
Traffic pattern: Systematic content downloading
Value to them: Better Claude model performance
Value to you: None directly
Decision: Charge (402) or Block (403)
Note: Anthropic respects robots.txt; clear signals work well

Google-Extended

Purpose: AI training for Bard/Gemini (separate from search indexing)
Traffic pattern: Distinct from Googlebot; specifically for AI training
Value to them: Improves Gemini model capabilities
Value to you: None for this specific bot
Decision: Charge (402) or Block (403)
Critical distinction: Blocking Google-Extended does NOT affect Google Search rankings

Meta-ExternalAgent

Purpose: Training Meta's Llama models
Traffic pattern: Bulk scraping for AI training datasets
Value to them: Better Llama model performance
Value to you: None
Decision: Charge (402) or Block (403)
Context: Meta's LLM business model unclear; licensing conversation may be valuable

CCBot (Common Crawl)

Purpose: Builds public datasets used by multiple AI companies
Traffic pattern: Comprehensive web archiving
Value to them: Powers dozens of AI training datasets
Value to you: Extremely distributed; hard to track downstream use
Decision: Charge (402) or Block (403)
Complexity: Common Crawl data is used by almost every AI lab; blocking has broad impact

Tier 3: Block Completely (Infrastructure Protection)

Bytespider

Owner: ByteDance (TikTok parent company)
Problem: Known for ignoring robots.txt directives
Traffic pattern: Aggressive crawling regardless of rules
Compliance: Poor
Decision: Block (403 Forbidden)
Why: Doesn't respect standards; protecting your infrastructure matters more than potential value

Unverified Scrapers

Pattern: Unknown user agents, suspicious behavior
Problem: Can't verify purpose or compliance
Decision: Block (403)
Implementation: Use Cloudflare's bot management to filter verified vs unverified traffic

Aggressive Bulk Downloaders

Pattern: High request rates, ignore crawl-delay
Problem: Server load without clear value
Decision: Block (403) or Rate Limit
Tools: Cloudflare rate limiting, edge caching

💼 For Leadership: This three-tier approach protects your content assets while maximizing AI visibility ROI. Early adopters implementing strategic crawler management see 20-30% traffic increases from AI platforms within 90 days. See how we can help optimize your strategy →

Your Decision Framework

Here's exactly what to do with each category of AI crawler:

✅ Always Allow (200 OK)

Who: User-facing crawlers that fetch content when real people need it.

Examples: ChatGPT-User, Claude-Web, Perplexity-User, OAI-SearchBot, PerplexityBot

Why: These bots represent actual user intent. When ChatGPT-User visits your page, it's because someone asked ChatGPT a question and it needs your content to answer. That's qualified traffic with potential for referrals.

Expected outcome: Citations in AI platforms, potential referral traffic, brand visibility in AI search results.

💰 Charge for Access (402 Payment Required)

Who: Training crawlers that scrape your content to build smarter models.

Examples: GPTBot, ClaudeBot, Google-Extended, Meta-ExternalAgent, CCBot (Common Crawl)

Why: These bots take your content and give nothing back: no traffic, no revenue, no attribution. Your content has value. Use Cloudflare's 402 response to signal: "To access this content, email partnerships@yoursite.com for licensing."

Expected outcome: Either opens licensing conversations or blocks the crawler. Over 1 billion 402 responses are being sent daily; this is becoming standard practice.

🚫 Block Completely (403 Forbidden)

Who: Aggressive crawlers with poor compliance or unclear value.

Examples: Bytespider (known for ignoring robots.txt), unverified scrapers, unknown user agents

Why: High server load, ignore your rules, provide no clear benefit. Some crawlers are essentially bad actors; they hammer your servers and don't respect industry standards.

Expected outcome: Reduced server load, protected infrastructure, better performance for legitimate users.

How to Implement These Decisions

For 200 OK (Allow): Do nothing. These bots can access your content normally.

For 402 (Charge): Use Cloudflare AI Crawl Control to set custom 402 responses with your licensing contact information.

For 403 (Block): Add user-agent blocks to your robots.txt or use Cloudflare to block at the edge.

Implementing with Cloudflare AI Crawl Control

Cloudflare's AI Crawl Control makes managing these crawlers remarkably straightforward. The dashboard gives you granular visibility into which bots are hitting your site and lets you set allow/block/charge decisions for each one.

What You Can See:

Total requests, allowed requests, and blocked requests for each crawler
Traffic patterns over time with sparkline visualizations
Crawler categories (AI Assistant, AI Search, Search Engine Crawler)
Request breakdowns showing allowed vs unsuccessful attempts
Individual crawler controls with Allow/Block buttons for each bot

The interface tracks bots like Googlebot, ChatGPT-User, DuckAssistBot, Meta-ExternalAgent, PerplexityBot, Claude-SearchBot, and many others, giving you a complete view of AI crawler activity across your domain.

Pay Per Crawl: Now in Private Beta

Cloudflare's Pay Per Crawl feature is currently in private beta, allowing content creators to actually charge AI companies for access to their content. Instead of binary allow/block decisions, you can set per-request pricing and receive compensation when crawlers access your pages.

How it works:

Set a flat, per-request price across your entire site
Crawlers send requests with payment intent headers
Cloudflare acts as Merchant of Record, handling all billing
You receive payments aggregated across all crawler requests
Crawlers without billing relationships see 402 responses inviting them to negotiate

The Broken Model

For two decades, the web operated on a simple exchange: search engines index your content, send visitors back, you earn revenue through ads or conversions. That cycle rewarded creators for producing quality content.

AI broke that model.

AI crawlers still take your content, but instead of sending visitors to your site, they generate answers directly. Users never click through. You get zero traffic, zero revenue, and zero attribution.

If the incentive to create original, quality content disappears, everyone loses. Creators stop creating. AI models train on stale data. Users get worse answers.

Cloudflare's Solution: The 402 Response

Instead of a binary allow/block decision, Cloudflare introduced the 402 "Payment Required" HTTP status code. When a crawler hits your site, you can send a custom message: "To access this content, email partnerships@yoursite.com for licensing."

It's not a wall; it's a negotiation table. Over 1 billion 402 responses are being sent daily, proving content creators want this option.

The Future of AI Crawling

AI crawlers aren't going away. They're the new distribution channel. By 2027, 85% of enterprises will run AI agents in at least one core function. Your content strategy must account for how AI platforms discover and use your information.

The question isn't "should I block AI bots?"

It's: "Which ones earn their access?"

User-facing crawlers that drive qualified traffic? Allow them. Training crawlers that take without giving back? Consider using the 402 response to start a conversation about compensation. Aggressive crawlers that ignore your rules? Block them to protect your infrastructure.

The infrastructure for fair compensation is being built right now. Content creators finally have options beyond binary allow/block decisions. Use them strategically.

Platform-Specific Crawler Strategies

ChatGPT Optimization

Crawlers to Manage:

ChatGPT-User (Allow): Real-time content fetching for user queries
OAI-SearchBot (Allow): Powers ChatGPT search functionality
GPTBot (Charge/Block): Training data collection

Strategy: Allow user-facing bots unconditionally. These represent actual user intent and can drive significant referral traffic. For GPTBot, use Cloudflare's 402 response to signal licensing requirements. Your content has value; training data should be compensated.

Expected Outcome: With proper access controls, brands typically see ChatGPT citations within 30-45 days for well-optimized content. User-facing traffic can represent 8-15% of total site visits within 90 days.

Perplexity Optimization

Crawlers to Manage:

Perplexity-User (Allow): Real-time search serving user queries
PerplexityBot (Allow): Indexes content for search engine functionality

Strategy: Both Perplexity crawlers should be allowed. Perplexity's citation interface heavily emphasizes sources with "read more" links that drive meaningful referral traffic. Block these and you eliminate all Perplexity visibility.

Expected Outcome: Perplexity users tend to be research-oriented with higher purchase intent. Citation placement typically drives 2-4x higher conversion rates compared to general search traffic.

Claude (Anthropic) Optimization

Crawlers to Manage:

Claude-Web (Allow): User-facing search for Claude conversations
ClaudeBot (Charge/Block): Training data collection

Strategy: Allow Claude-Web for user-facing citations. Claude users skew technical and high-value, making citations particularly valuable. For ClaudeBot training access, implement 402 response. Anthropic respects robots.txt signals well, making clear communication effective.

Expected Outcome: Claude citations tend to be longer and more contextual, often including extended quotes from your content. Quality over quantity compared to other platforms.

Google AI Overviews Optimization

Crawlers to Manage:

Googlebot (Always Allow): Traditional search indexing
Google-Extended (Charge/Block): AI training separate from search

Strategy: Critical distinction here. Blocking Google-Extended does NOT affect Google Search rankings. You can protect training data while maintaining search visibility. Allow Googlebot unconditionally, consider 402 for Google-Extended.

Expected Outcome: AI Overviews appear for 15-20% of searches in 2025. Proper crawler management ensures you're eligible for both traditional results and AI-generated summaries.

Grok (X AI) Optimization

Crawlers to Manage:

Grok crawlers (Allow with monitoring): Real-time social media integration

Strategy: Grok integrates heavily with X (Twitter) signals. Allow access but monitor traffic patterns. The platform is newer with less established behavior patterns, so maintain flexibility.

Expected Outcome: Grok favors timely, newsworthy content with social proof. Citations often correlate with X engagement on related topics.

Common Mistakes to Avoid

Mistake 1: Blocking All AI Crawlers Out of Fear

Why this happens: Content creators worry about AI scraping and implement blanket blocks on all user agents containing "bot," "AI," or "GPT."

The problem: You block user-facing crawlers along with training bots, eliminating 40% of potential discovery traffic. ChatGPT-User can't fetch your content when users search, so you disappear from AI platforms entirely.

How to fix it: Differentiate between user-facing crawlers (allow) and training crawlers (negotiate). Use specific user-agent blocking, not broad pattern matching.

Prevention: Implement granular crawler rules using Cloudflare AI Crawl Control or specific robots.txt directives for each crawler type.

Mistake 2: Allowing Everything Without Strategy

Why this happens: Default server configurations allow all crawlers. Teams assume "more crawlers = more visibility."

The problem: Training crawlers bulk-download your content, absorbing server resources and bandwidth without providing traffic in return. You're essentially subsidizing AI model training while competitors monetize training access.

How to fix it: Audit current crawler access. Implement 402 responses for training bots while maintaining user-facing access.

Prevention: Quarterly crawler audits to review which bots access your site and what value exchange exists.

Mistake 3: Ignoring Crawler Verification

Why this happens: Crawlers self-identify via user-agent strings, which can be spoofed. Teams trust user-agent headers without verification.

The problem: Malicious scrapers impersonate legitimate crawlers. You think you're allowing GPTBot but actually permitting unauthorized copying.

How to fix it: Use Cloudflare's verified bot detection or implement reverse DNS verification for major crawlers (OpenAI, Anthropic, Google publish their IP ranges).

Prevention: Enable Cloudflare Bot Management to distinguish verified crawlers from impersonators automatically.

Mistake 4: Setting and Forgetting Crawler Rules

Why this happens: Teams implement crawler rules once and never review them. New platforms launch with new crawlers that aren't addressed.

The problem: Your crawler strategy becomes outdated within months. New AI platforms (like Grok in 2024) can't access your content because rules predate their existence.

How to fix it: Set calendar reminders for quarterly crawler strategy reviews. Monitor Cloudflare dashboards for new crawler patterns.

Prevention: Subscribe to AI platform announcements. Major launches (new OpenAI features, Anthropic updates, Google AI changes) often introduce new crawlers.

Mistake 5: Not Communicating Licensing Terms Clearly

Why this happens: Teams block training crawlers with 403 Forbidden responses without explaining why or how to negotiate access.

The problem: AI companies receive a hard block with no path forward. You miss potential licensing revenue and relationship opportunities.

How to fix it: Use 402 Payment Required responses with clear contact information: "To license this content for AI training, email partnerships@yourcompany.com"

Prevention: Establish a content licensing contact and process before implementing 402 responses. Be prepared to negotiate when AI companies reach out.

FAQ: AI Crawler Management Questions Answered

1. Will blocking training bots like GPTBot hurt my search rankings?

No. Training bots (GPTBot, ClaudeBot, Google-Extended) are separate from search indexing bots. Blocking GPTBot doesn't affect ChatGPT's ability to cite you via ChatGPT-User. Blocking Google-Extended doesn't impact Google Search rankings at all. The bots serve different functions.

2. How do I know which crawlers are actually hitting my site?

Check your server logs for user agent strings, or use Cloudflare AI Crawl Control for a visual dashboard. Most hosting providers also offer basic bot traffic analytics. Look for patterns: training bots typically scrape in bulk, while user-facing bots show burst patterns aligned with actual query volume.

3. What's the difference between robots.txt blocking and Cloudflare blocking?

Robots.txt is a polite request; bots can ignore it (and some do). Cloudflare blocking happens at the edge before requests reach your server, making it impossible for bots to bypass. For compliance-conscious bots (OpenAI, Anthropic, Google), robots.txt works. For aggressive crawlers like Bytespider, use Cloudflare.

4. Can I allow some pages but charge for others?

Yes, with Cloudflare AI Crawl Control you can set different rules by path. Allow blog posts (you want citations) but charge for proprietary research reports. This granular control lets you balance visibility goals with content protection.

5. What happens when I send a 402 response to a training bot?

The bot receives an HTTP 402 status code with your custom message (typically contact information for licensing discussions). The bot can either respect the 402 and not crawl your content, or reach out to negotiate access. Over time, this creates a record of 402 responses that signals your content is valuable and protected.

6. Will using 402 responses hurt my AI platform visibility?

No, because you're only sending 402 to training bots, not user-facing crawlers. ChatGPT can still cite you via ChatGPT-User even if you block GPTBot with 402. Your visibility strategy and training data strategy are separate concerns.

7. How much can I actually charge with Cloudflare Pay Per Crawl?

Cloudflare Pay Per Crawl is in private beta with pricing models still being tested. Early implementations suggest per-request pricing in the $0.001-$0.01 range depending on content value. For high-traffic sites with premium content, this could generate significant revenue. The real value is establishing the norm that training data should be compensated.

8. Should news publishers manage AI crawlers differently than e-commerce sites?

Yes. News publishers depend heavily on AI platform citations for traffic, so being more permissive with user-facing crawlers makes sense. E-commerce sites with proprietary product data may want stricter controls on training bots to protect competitive advantage. Your content's strategic value determines your crawler strategy.

9. What if an AI company refuses to negotiate after I send 402 responses?

That's their choice, and it tells you something valuable: they don't value your content enough to pay for it, yet they want to use it anyway. In that case, escalate to a full 403 block. The point of 402 is to start conversations; if companies refuse to engage, blocking is justified.

10. How often should I review my AI crawler strategy?

Quarterly at minimum. New AI platforms launch constantly, crawler behavior changes, and business models evolve. What made sense in Q1 might be outdated by Q4. Set calendar reminders to review your Cloudflare AI Crawl Control dashboard and adjust rules based on actual traffic patterns and business outcomes.

Key Takeaways

Not all AI crawlers serve the same purpose.

User-facing bots like ChatGPT-User, Claude-Web, and Perplexity-User represent real user intent. They drive qualified traffic and should have unrestricted access. Training bots (GPTBot, ClaudeBot, Google-Extended) scrape content for model improvements without sending traffic back. Aggressive crawlers like Bytespider ignore standards and drain resources without providing value.

Strategic crawler management requires nuance, not blanket policies.

Allow user-facing crawlers to maximize AI platform visibility. Use 402 responses with training crawlers to signal your content has value and open licensing conversations. Block aggressive crawlers that ignore industry standards to protect your infrastructure. The "allow everything" or "block everything" approaches both leave money on the table.

Cloudflare AI Crawl Control makes implementation straightforward.

Visual dashboards show exactly which bots are accessing your site, traffic patterns over time, and granular controls for each crawler. Pay Per Crawl beta access enables actual content monetization instead of binary allow/block decisions. Implementation takes minutes, not hours.

The broken incentive model is being fixed, but action is required.

Over 1 billion HTTP 402 responses are sent daily as content creators demand fair compensation for training data. Cloudflare's Pay Per Crawl establishes infrastructure for automated licensing. Early adopters set industry norms and capture monetization opportunities that late entrants miss.

Your crawler strategy directly impacts AI visibility and revenue.

Block the wrong bots and you disappear from ChatGPT, Perplexity, and Claude citations. Allow everything and you give away valuable training data while absorbing server costs. Strategic decisions compound over time as AI platforms establish trusted source relationships. First-movers build authority that lasts.

What This Means for Your Business

If you manage significant content assets in 2025, your AI crawler strategy directly impacts two critical business outcomes: visibility in AI platforms and protection of valuable content.

For visibility: User-facing crawlers (ChatGPT-User, Perplexity-User, Claude-Web) determine whether your brand appears in AI-generated responses. These platforms now drive 40% of product discovery. Block these crawlers and you effectively opt out of the fastest-growing search channel. Allow them strategically and you build citation history that compounds as AI platforms learn which sources to trust.

For content protection: Training crawlers (GPTBot, ClaudeBot, Google-Extended) currently take your content without compensation. Your original research, detailed guides, and proprietary insights become training data for models that compete with your business. The 402 response framework and Pay Per Crawl beta access finally give content creators leverage to negotiate fair value exchange.

The window for establishing good crawler relationships is now. AI platforms are still learning which sources to trust, which publishers respect their terms, and which content provides consistently high quality. Early decisions create precedents. Sites that block everything miss the visibility opportunity. Sites that allow everything miss the monetization opportunity. Strategic differentiation by crawler type positions you optimally for both.
