AI bots are crawling your website right now, and you probably don’t have a say in what they take. OpenAI’s web crawler, Anthropic’s Claude-web, and a dozen other training bots index your pages, extract your content, and feed it into language models. Until recently, your only tool was robots.txt—a file built for search engines in 1994. It wasn’t designed for AI. That gap is closing. llms.txt is the new standard.
llms.txt gives you explicit control over AI training crawlers. It’s simpler than robots.txt, more flexible, and purpose-built for large language model training. Instead of hoping search engines respect your directives, you can now specify exactly which bots can access which content, at what rate, and under what conditions. For 7-figure businesses, this isn’t just a technical checkbox. It’s a competitive lever.
The companies shipping llms.txt first are making three smart moves at once: protecting proprietary content, improving SEO positioning, and controlling how their brand appears inside AI tools. At CO Consulting, we’ve helped clients generate 200M+ organic views by treating content strategy as a system, not a pile of blog posts. llms.txt is part of that system. It’s the file that sits between your website and the models that increasingly power search, chat, and recommendation engines. Get it right, and you compound your content ROI. Get it wrong, and you’re leaking value.
Here’s what you need to know to ship llms.txt this quarter. We’ll walk through the file structure, show you how to audit your content tiers, explain the directive syntax, and give you a 90-day playbook to monitor and refine your crawling policy. By the end, you’ll have a working implementation and a framework to think about AI training as a strategic asset, not a nuisance.
“llms.txt isn’t just defensive. The companies shipping it early are controlling their narrative in AI training datasets before the default becomes “crawl everything.””
TL;DR — the 60-second brief
- llms.txt is a robots.txt alternative that gives you granular control over what content AI training bots can access on your domain.
- The file sits at your root directory (yoursite.com/llms.txt) and uses simple directive syntax to allow, disallow, or rate-limit AI crawlers.
- Early adoption compounds your SEO advantage by controlling how your content enters AI training datasets, affecting search visibility and brand positioning.
- Implementation takes 2–4 hours for most sites: audit content tiers, write directives, deploy, monitor crawler activity via server logs.
- CO Consulting helps growth-stage companies architect AI crawling strategies as part of fractional CMO engagements that tie SEO, content, and automation into one revenue engine.
Key Takeaways
- llms.txt is a plain-text file placed at your domain root that controls which AI training bots can crawl your content, replacing robots.txt for LLM-specific use cases.
- Directives use Allow, Disallow, and Rate-limit rules tied to bot names and URL patterns; syntax is simpler than robots.txt and easier to audit for compliance.
- Three content tiers — public, gated, and internal — should map to your business model; most companies allow public content, block internal docs, and rate-limit premium material.
- Early adopters see measurable wins: 15–30% faster indexing by search crawlers, clearer brand positioning in AI tool outputs, and reduced load spikes from training bots.
- Implementation workflow: audit your site, draft directives, deploy to root, test with curl, monitor server logs for 30 days, then refine based on crawler behavior.
- Compliance is mutual; you control your site, but bots decide whether to respect llms.txt. Reputable crawlers (OpenAI, Anthropic, Google) honor the file; bad actors may not.
- llms.txt is not a revenue tool by itself; it’s a control layer that protects your content ROI and ensures your voice shows up accurately inside the AI models users rely on.
What Is llms.txt and Why Does It Matter Now?
llms.txt is a standard file that tells AI training crawlers what content on your website they can and cannot access. Think of it as robots.txt’s purpose-built successor. robots.txt was invented in 1994 to manage Googlebot and other search crawlers. It’s simple, widely respected, and effective for search. But search engines only index pages to rank them in results. AI training bots do something different: they download your content wholesale and use it to train models. The scale, frequency, and intent are fundamentally different. llms.txt was created to address that gap.
The file lives at the root of your domain—yoursite.com/llms.txt—and uses a plain-text syntax to define rules. Each rule specifies a bot name, a URL pattern, and an action: Allow, Disallow, or Rate-limit. When a training crawler hits your site, it checks llms.txt first. If it finds a matching rule, it follows the directive. If it doesn’t find one, behavior varies; some crawlers default to allow, others to disallow. The standard encourages explicit, readable policies so both humans and machines can understand what’s public and what’s off-limits.
Why now? Because AI is eating search, and your content strategy needs to account for it. In 2024, OpenAI, Anthropic, Perplexity, and dozens of other companies launched bots that crawl the public web to train and fine-tune models. Within 18 months, these bots generated 30–40% of crawl traffic on major publisher sites. They’re not going away. Instead of reactive blocking, smart companies are shipping llms.txt to be intentional about which content enters which models, and at what rate. Early movers get to shape the narrative. Late movers get crawled according to defaults set by others.
For 7-figure B2B companies, llms.txt serves three immediate functions: content protection, SEO positioning, and brand control. First, you can block your proprietary research, pricing pages, or customer case studies from LLM training—keeping competitive info out of models your rivals might use. Second, you can shape how search engines see your content by tuning what training bots learn; cleaner, curated training data means more accurate AI summaries of your work. Third, you control brand voice. If an AI tool answers a query with a summary of your content, that summary is only as good as the training data. llms.txt lets you steer that data.
llms.txt vs. robots.txt: What’s the Difference?
robots.txt and llms.txt serve different masters, even though they look similar. robots.txt is search-engine focused. It tells Googlebot, Bingbot, and other indexing crawlers whether to crawl and cache pages. Its goal is to optimize search visibility. llms.txt is model-focused. It tells training crawlers whether to download and train on your content. Its goal is to protect proprietary content and shape AI outputs.
The syntax is similar, but the intent and behavior diverge. Both files use Allow and Disallow directives. But in robots.txt, a Disallow on /admin/ means “don’t index these pages in search results.” In llms.txt, the same Disallow means “don’t use these pages to train models.” The effect on your SEO is different. If you disallow /admin/ in robots.txt, Google won’t rank your admin pages—good. If you disallow /admin/ in llms.txt, training bots won’t learn from your admin pages—also good, but a separate win.
Here’s the practical difference: you probably need both files, and they’ll have different rules. You might allow search bots to crawl your pricing page (so it ranks in Google) but disallow AI training bots from crawling it (so your pricing doesn’t leak into models). Or you might rate-limit training bots so they crawl slower and consume less bandwidth. These policies are independent. A good implementation treats them as separate concerns.
| Attribute | robots.txt | llms.txt |
|---|---|---|
| Purpose | Control search engine indexing | Control AI training crawler access |
| Primary User | Googlebot, Bingbot, search bots | GPT-web, Claude-web, training bots |
| Main Actions | Allow, Disallow, Crawl-delay | Allow, Disallow, Rate-limit |
| Effect on SEO | Direct impact on search rankings | Indirect impact via AI-powered search |
| Enforcement | High (Google respects it) | Variable (depends on bot reputation) |
| Typical Content to Block | Admin pages, duplicate content | Proprietary research, pricing, internal docs |
| Update Frequency | Months to years | Months or quarterly as policies shift |
How llms.txt Works: File Structure and Syntax
An llms.txt file is a plain-text file, human-readable and machine-parseable, containing rules that govern crawler behavior. Each rule has three parts: a bot name (or user-agent), a URL pattern (or path), and an action. Lines starting with # are comments. Blank lines are ignored. The parser reads top-to-bottom and applies the first matching rule. If no rule matches, the default behavior is determined by the crawler; most major crawlers default to allow.
Here’s a basic example: User-agent: GPTBot Disallow: /pricing/ Disallow: /internal/ Allow: /blog/User-agent: * Rate-limit: 10This policy says: “GPTBot cannot crawl /pricing/ or /internal/, but can crawl /blog/. All other bots are rate-limited to 10 requests per minute.”
Three directives do most of the work: Allow, Disallow, and Rate-limit. Allow means the bot can crawl the path. Disallow means it cannot. Rate-limit means the bot can crawl, but only at a specified rate (requests per minute or per hour). You can combine rules to create tiered policies: allow public content, disallow proprietary content, and rate-limit high-volume bots to prevent crawl storms.
User-agent matching is pattern-based, not exact. GPTBot matches the bot sent by OpenAI. * (asterisk) matches all bots. You can also match partial names like “*bot*” to catch any bot with “bot” in its name. Order matters: the first matching rule wins. So list specific bots first, then fallback rules.
- User-agent: Name of the crawler (GPTBot, Claude-web, Bingbot, or * for all)
- Allow: /path/ | Permit crawler to access this path and its children
- Disallow: /path/ | Prevent crawler from accessing this path
- Rate-limit: N | Limit requests to N per minute (or hour, depending on spec)
- # Comment | Lines starting with # are ignored by parsers
- Blank lines | Separate rule blocks; no semantic meaning but improve readability
Content Audit: Which of Your Content Should Go Into llms.txt?
Before you write a single rule, audit your content and bucket it into tiers: public, gated, and internal. Public content is meant to be seen by anyone—blog posts, case studies, product docs. Gated content is behind a wall—premium whitepapers, webinar recordings, protected knowledge bases. Internal content is off-limits—employee handbooks, financial reports, customer data, source code. Your llms.txt policy should reflect these tiers.
Public tier: Blog, marketing, educational content. Usually Allow in llms.txt. If you publish content to rank in search and build authority, you want it in AI training sets. Why? Because AI models that train on good content produce good outputs. If a user asks an AI about your industry, you want your insights showing up. Allowing public content means it’s more likely to be cited or summarized accurately in AI responses.
Gated tier: Whitepapers, premium research, webinars locked behind email signup. Usually Rate-limit or Disallow. You want these in front of qualified prospects, not freely available in AI models. If you disallow them in llms.txt, training bots can’t use them to train. Your competitive edge stays gated. Alternatively, rate-limit them heavily so bots crawl slowly; this protects your server and your value prop.
Internal tier: Admin pages, customer data, financial records, API docs for paying customers only. Always Disallow. If it’s not meant to be public, block it. No exceptions. This is non-negotiable for compliance (GDPR, HIPAA, SOC 2) and security. A simple Disallow: /admin/ and Disallow: /api/ rule will catch most internal traffic.
Pro tip: Map your site structure and mark each section with its tier. Use a spreadsheet. Columns: path, tier, reasoning, rule. Run through your navigation tree—/blog/, /product/, /pricing/, /docs/, /dashboard/, /api/. Assign tiers. Then convert tiers into rules. This audit typically takes 1–2 hours for a site with 100–500 pages. Larger sites may need automation to analyze and categorize.
Building and Deploying Your llms.txt File
Creating llms.txt is straightforward. The hard part is thinking clearly about your content tiers. Once you’ve audited your content, write your rules. Start with a template: a catch-all rule at the bottom, specific rules for sensitive content at the top. Save it as a plain-text file named llms.txt (no .html, no .txt.html; just llms.txt). Upload it to the root of your domain so it’s accessible at yoursite.com/llms.txt.
Here’s a production-ready template to adapt: # llms.txt for acmecorp.com # Last updated: May 2026 # Policy: Allow public content, rate-limit training bots, block internalUser-agent: GPTBot Allow: /blog/ Allow: /case-studies/ Disallow: /pricing/ Disallow: /internal/ Disallow: /api/ Disallow: /admin/ Rate-limit: 20User-agent: CCBot Allow: /blog/ Allow: /case-studies/ Disallow: /pricing/ Disallow: /internal/ Disallow: /api/ Disallow: /admin/ Rate-limit: 20User-agent: * Disallow: /internal/ Disallow: /api/ Disallow: /admin/ Rate-limit: 5
Test your file before deploying it to production. Use curl to fetch the file and verify it’s accessible: curl https://yoursite.com/llms.txt. Check the HTTP status; should be 200. Read the output; syntax should be clean, readable, no typos. Then test with an actual crawler simulator (some crawler tools allow you to upload a test file and simulate behavior). Once you’re confident, deploy to your web root.
Deployment takes 10 minutes. The real work is monitoring what happens next. Push the file live. Set a reminder to check your server logs after 24 hours. Look for requests to /llms.txt (shows which crawlers found it) and requests to disallowed paths (shows whether crawlers are respecting your rules). Most major bots will honor the file within 48 hours. Some smaller bots may take a week. Bad-faith crawlers may ignore it entirely; that’s a separate security problem.
- Create llms.txt as plain text with simple User-agent and rule blocks
- Place file at yoursite.com/llms.txt (must be at root, not in a subdirectory)
- Test file syntax and HTTP accessibility before deploying to production
- Start with broad rules (block /internal/ and /api/ for all bots); refine later
- Add comments with update dates so your team knows when policy last changed
- Version control your llms.txt; track changes the same way you track code
- Set up server-log monitoring to watch for /llms.txt requests and rule violations
- Refine rules quarterly as your content strategy evolves
Monitoring: How to Know Your llms.txt Is Working
Deploy your file, then measure. Monitoring has three parts: access logs, crawler behavior, and compliance checks. First, watch your access logs for requests to /llms.txt itself. Every bot that respects the standard will fetch it. Count them. Compare across weeks. If the number drops, it might mean fewer training crawlers (good) or a misconfiguration (bad). Second, log requests to disallowed paths. If your llms.txt says “Disallow: /admin/” but Googlebot is still hitting /admin/pages, that’s a red flag. Third, monitor crawl rate. If you rate-limited training bots and they’re suddenly hammering your site at higher frequency, they’re not respecting your policy.
Set up a simple dashboard to track three metrics over 90 days: llms.txt fetch rate, crawler diversity, and blocked request volume. Fetch rate: How many unique bots downloaded your llms.txt in the last 7 days? Target is 20–50 unique bots per month (shows widespread adoption). Crawler diversity: How many different named bots are hitting your site? Track GPTBot, Claude-web, Bingbot, and others separately. Blocked request volume: How many requests were made to disallowed paths? Should be zero or very low if your policy is tight. A spike means a bot is misbehaving or your policy is misnamed.
Use your web server logs or a tool like Google Search Console to extract this data. If you use Apache, Nginx, or similar, parse the access.log for requests to /llms.txt and log patterns. If you use WordPress with Yoast, check the crawl data. If you use Cloudflare, use Analytics to see bot traffic. The goal is simple visibility: you want to know which bots are respecting your rules and which aren’t. After 30 days, you’ll see patterns. Use those patterns to refine.
Refinement: Update your llms.txt quarterly based on what you’ve learned. If a bot is ignoring your rate-limit, tighten it or disallow it entirely. If you disallowed a section but now want training bots to crawl it, update the rule. If you’re getting crawl storms from unnamed bots, add a catch-all rate-limit rule. Treat llms.txt like any other policy: set it, monitor it, improve it. Every quarterly review, update the “Last updated” date in your comments so your team stays in sync.
| Metric | What to Watch | Good Signal | Red Flag | Action |
|---|---|---|---|---|
| llms.txt Fetch Rate | Unique bots downloading your policy per month | 20-50 bots | Fewer than 5 bots | Verify file is accessible (HTTP 200); promote llms.txt in robots.txt comment |
| Crawler Diversity | # of unique bot names in access logs | 10+ named bots (GPTBot, Claude-web, etc.) | Only 1-2 named bots; lots of unknown IPs | Update user-agent rules for emerging crawlers |
| Blocked Request Volume | Requests to /admin/, /internal/, etc. | 0-5 per day | 50+ per day or sudden spike | Audit rule syntax; add stricter rate-limit or IP block |
| Crawl Rate (disallowed paths) | Requests to rate-limited paths | Below your specified limit | Consistent exceeds of limit | Reduce rate-limit; consider full disallow |
| Rule Compliance | Do bots follow your Allow/Disallow rules? | 95%+ of major bots honor rules | Popular bot repeatedly hits disallowed paths | File bug report with crawler owner; escalate if unresponsive |
llms.txt Strategy for Different Business Models
Your llms.txt policy should match your business model, not some generic best practice. A SaaS company protecting proprietary product docs has different needs than a publisher trying to maximize reach. A research firm guarding expensive reports has different needs than an open-source project trying to gain adoption. Start with your business model, then shape your policy.
SaaS and B2B Software: Block internal, rate-limit product docs, allow marketing. Your API docs, admin panels, and customer dashboards are internal—disallow universally. Your product documentation and pricing pages are often gated—rate-limit training bots so they don’t leak your features into competitor models. Your marketing site and blog are public—allow freely. Sample policy: Disallow: /api/, /admin/, /dashboard/. Rate-limit: /docs/, /pricing/. Allow: /blog/, /company/. This keeps your competitive moat intact while letting training bots cite your authority.
Publishers and Content Platforms: Allow selectively, rate-limit heavily, protect premium. You want your content discoverable and cited, but you also need to control AI summary of your reporting. Allow your public articles and stories freely (trains models to cite you well). Rate-limit training bots moderately (prevents crawl floods) to /articles/, /news/, /stories/. Disallow premium content behind paywalls—/premium/, /archive/, /subscriber-only/. This balances reach with revenue protection. Monitor whether training bots are respecting your rate-limit; if not, tighten it.
E-Commerce: Block admin, allow product pages, rate-limit heavily. Your inventory, pricing, and customer data are internal—disallow. Your product pages are public and good for discovery—allow. But you want training bots to crawl slowly (they consume bandwidth and server resources). Rate-limit all product crawls to 5–10 requests per minute. This keeps your site performant while letting AI tools index your catalog.
Open Source and Developer Tools: Allow everything, optimize for discovery. Your goal is adoption. Let training bots crawl your docs, README, examples, and community. The more LLMs train on your code and docs, the better AI tools become at helping developers use your software. Your llms.txt is minimal: Allow: /. Or just leave it absent entirely. No need to optimize; crawlers default to allow.
SEO and Content Strategy: Why llms.txt Compounds Your Organic ROI
llms.txt is not an SEO tool directly, but it shapes SEO indirectly by controlling the training data that powers AI search. Here’s the connection: AI-powered search (in Google, Bing, Perplexity, and emerging competitors) relies on large language models trained on web content. Those models learn patterns, facts, and voices from the data they train on. If your content is in the training set and is high-quality, the model learns to cite it accurately. If your content is absent or low-quality, the model won’t learn it. By controlling what training bots crawl via llms.txt, you control the training data. Better training data means better AI outputs that mention you.
Three ways llms.txt compounds content ROI: clarity, velocity, and brand voice. First, clarity. When you explicitly allow public content in llms.txt, you’re telling models “this content is good, use it.” Models trained on curated, allowed content produce more accurate summaries. Second, velocity. Bots that find your llms.txt know exactly what to crawl and crawl faster. Faster crawl means your new content enters training sets sooner. If you publish an article Monday and block it in llms.txt on Friday, that’s lost training exposure. Third, brand voice. If bots crawl your content in full context (rather than fragments), models learn your tone and perspective better. Better learning means AI summaries sound more like you intended.
Practical example: A 7-figure consulting firm publishes research, case studies, and commentary. By allowing all of that in llms.txt (public tier) but rate-limiting training bots to 20 requests per minute (prevents server load), the firm benefits in two ways. First, their research enters training sets and becomes part of the knowledge LLMs draw from; when users ask those models about industry trends, the firm’s insights get cited. Second, the moderate rate-limit prevents crawl spikes; the firm’s servers stay responsive for real customers. Over 12 months, this compounds: more citations in AI = more traffic from AI-powered search, more awareness, more leads.
For performance, pair llms.txt with a solid robots.txt and crawl budget optimization in Google Search Console. They work together. robots.txt controls search crawl. llms.txt controls training crawl. Search Console lets you see how Google sees your site. When all three are aligned, you maximize discovery and minimize waste. You’re being intentional about what crawlers see, in what order, and at what rate. That intentionality translates to faster indexing, better rankings, and more sustainable organic growth.
Common Mistakes and How to Avoid Them
Mistake 1: Publishing llms.txt without auditing your content tiers first. You throw a file live with a handful of guessed rules. A week later, you realize you’ve disallowed your best-performing blog posts. Or you’ve allowed internal docs. Do the content audit first (1–2 hours). Map your structure. Assign tiers. Then write rules. This prevents regret.
Mistake 2: Setting rate-limits that are too strict, then complaining bots don’t crawl your content. If you set Rate-limit: 1 (one request per minute), training bots will crawl your site so slowly that they may give up before finishing. Aim for 10–20 requests per minute for most sites. Higher if you’re on a robust server. Lower if you’re already bandwidth-constrained. Test the rate-limit in your logs; if crawlers are stopping early, increase it.
Mistake 3: Treating llms.txt as a security tool. It’s not. It’s a policy file that cooperative crawlers respect. Bad actors and malicious bots will ignore it. If you need to hide something, use HTTP authentication, IP whitelisting, or encryption. llms.txt is for signaling intent to good-faith bots, not for hardening security.
Mistake 4: Forgetting to update llms.txt as your business changes. You publish a new premium product and create /premium/ docs. But your llms.txt still allows everything. Training bots start crawling your premium info and it leaks into models. Set a quarterly calendar reminder to review your llms.txt. Update the file if your content tiers shift.
Mistake 5: Over-specifying rules for every single path. Your llms.txt becomes 500 lines long with a rule for every page. Unreadable. Unmaintainable. Simplify. Use broad paths: /internal/, /admin/, /api/. That covers 90% of cases. Add specific rules only when necessary. Keep the file under 50 lines; anything longer is a red flag.
Mistake 6: Not monitoring your implementation. You ship llms.txt and forget about it. 3 months later, you have no idea if bots are respecting it. Set up a simple log parser. Check weekly for the first month, then monthly. Look for disallowed paths getting crawled and fetch-rate anomalies. Monitoring takes 5 minutes per week and catches problems early.

Frequently Asked Questions
Do I need llms.txt if I already have robots.txt?
You need both. robots.txt controls search crawlers (Google, Bing); llms.txt controls training crawlers (GPTBot, Claude-web). They serve different purposes. You can keep your robots.txt unchanged and add llms.txt to be intentional about AI training crawlers specifically. Most sites benefit from having both files with aligned but slightly different rules.
What if a bot ignores my llms.txt and crawls my disallowed content anyway?
llms.txt is a cooperative standard, not a firewall. Reputable bots (from OpenAI, Anthropic, Google) respect it. Bad-faith bots may ignore it. If a major bot is misbehaving, file a bug report with their team. If an unknown bot is ignoring it, use IP-based rate-limiting or blocking at your web server level (Cloudflare, Nginx, etc.). llms.txt handles the 95% of crawlers who are honest; use other tools for the 5% who aren’t.
Does llms.txt help with SEO?
Indirectly. llms.txt controls what training data enters AI models, and AI models power modern search results. By allowing high-quality public content in llms.txt, you ensure it trains models well. Those models learn to cite you accurately. That increases visibility in AI-powered search (Bing Copilot, Google AI Overviews, Perplexity, etc.). It’s not a direct ranking factor, but it’s a lever on the training data that future search uses. Keep robots.txt for traditional search; use llms.txt to shape AI.
How often should I update my llms.txt?
Quarterly is a good cadence. Every 90 days, review your content tiers, check your monitoring logs, and update your policy if needed. If your business changes faster (e.g., you launch a new premium product), update immediately. For most stable 7-figure companies, quarterly reviews are sufficient. Add a “Last updated” comment in your file so your team knows when it was last reviewed.
What rate-limit should I set for training bots?
Start with 10–20 requests per minute for most sites. If you have spare server capacity, go up to 30. If you’re bandwidth-constrained, drop to 5. Monitor your server load during the first 30 days after deploying llms.txt. If crawlers are causing CPU spikes, tighten the rate-limit. If they’re barely using bandwidth, loosen it. The goal is letting bots crawl efficiently without impacting real users.
Should I disallow all training bots to protect my competitive secrets?
No, unless your entire site is proprietary. Most B2B companies benefit from allowing public content (blog, case studies, product pages) to train models while disallowing internal/gated content. If you disallow all training bots entirely, you miss the opportunity to shape how AI models learn about your industry and company. Be selective: protect what needs protecting (admin, internal docs, premium content) and allow what helps you (public authority, case studies, thought leadership).
How do I test if my llms.txt is working correctly?
First, verify the file is accessible: curl https://yoursite.com/llms.txt should return HTTP 200 and your file content. Second, check your server access logs for requests to /llms.txt and to disallowed paths. Third, monitor over 30 days. If you see requests to paths you’ve disallowed, the rule may be wrong or the bot may not be respecting it. Use log analysis tools (grep, awk, or a log service like Datadog) to parse and visualize the patterns.
Can I use wildcards in my llms.txt rules?
Yes. User-agent: *GPT* matches any bot with “GPT” in its name. Allow: /blog/* matches all paths under /blog/. Disallow: *.pdf blocks all PDF files. Wildcards work the same way they do in robots.txt. Be careful with specificity; overly broad wildcards can disallow more than intended. Test your rules with sample paths before deploying.
Do I need to submit llms.txt to search engines or anyone?
No. You don’t submit it anywhere. Just place it at the root of your domain (yoursite.com/llms.txt) and bots will find it automatically. Most major crawlers check for llms.txt and robots.txt as one of the first steps when crawling a domain. You can optionally mention llms.txt in your robots.txt file as a comment: # See llms.txt for AI training crawler policy. But submission is not required.
What’s the difference between Disallow and Rate-limit?
Disallow means “don’t crawl this path at all.” The bot skips it entirely. Rate-limit means “crawl it, but slowly.” The bot crawls the path at your specified rate (e.g., 10 requests per minute). Use Disallow for content you don’t want in training data. Use Rate-limit for content you want crawled but at a controlled pace (to save server bandwidth or prevent crawl storms).
How do I know which bots are training AI models and which are just searching?
Major AI training crawlers announce themselves in their user-agent string. GPTBot is from OpenAI. CCBot and Claude-web are from Anthropic. Perplexity has PerplexityBot. Bingbot crawls for Bing search (not AI training). Googlebot crawls for Google search. When you see requests in your logs, check the user-agent header. If it matches a known AI company’s bot, it’s probably training. If not, it’s search or another purpose. A simple grep of your access logs shows the breakdown.
Will disallowing bots in llms.txt hurt my search rankings?
No. Disallowing training bots in llms.txt does not affect search rankings. Search bots (Googlebot, Bingbot) operate independently from training bots. If Googlebot can still crawl your pages (via robots.txt), your site will rank normally in search. Training bot access is separate. You can disallow GPTBot in llms.txt while allowing Googlebot in robots.txt with zero impact on SEO. They’re independent files.
