When to Use Disallow, Allow & No-Index

robots.txt disallow all

User-agent: *
Disallow: /

robots.txt allows all

User-agent: *
Allow: /

robots.txt no index

Robots.txt doesn't support "noindex" anymore.

Use this HTTP header instead:

X-Robots-Tag: noindex

Crawl-delay

Asks bots to wait a set number of seconds between requests. Useful if your server has limited resources. Note: Google ignores this directive — use Google Search Console to manage Googlebot's crawl rate instead.

Crawl-delay: 10

Advanced crawl control

Need different rules for different bots? The tool supports multiple User-agent declarations, so you can allow Googlebot full access while blocking SemrushBot or restricting Bingbot to specific sections. This is useful for:

• Agencies managing client sites with third-party audit tools
• Large sites where different crawlers have different priorities
• Sites undergoing migration where crawl behaviour needs to be tightly controlled

Block AI crawlers from training on your content

AI companies train large language models by crawling the web. If you don't want your content used as training data, you can block AI crawlers in your robots.txt file.
The most common AI bots to block are:

• OpenAI : GPTBot
• Anthropic :ClaudeBot
• Common Crawl : CCBot
• Google (Gemini) : Google-Extended
• Add these rules to block all four:

User-agent: GPTBot
Disallow: /

User-agent: ClaudeBot
Disallow: /

User-agent: CCBot
Disallow: /

User-agent: Google-Extended
Disallow: /

Note: robots.txt is a voluntary standard. Most reputable AI companies respect it, but it isn't legally enforceable. For stronger protection, use Terms of Service language alongside robots.txt rules.

Google Robots.txt Recommendations

Google recommends:

• Do NOT block CSS & JS
• Do NOT use robots.txt for confidential data
• Always specify the correct robots txt format
• Provide a sitemap reference

Our tool applies these automatically.

Google's robots.txt best practices

Following Google's guidelines prevents accidental crawl blocks that can tank rankings:

• Never block CSS or JavaScript — Google needs these to render and evaluate your pages
• Don't rely on robots.txt for sensitive data — blocked URLs can still be discovered via links; use authentication instead
• Always include a sitemap reference — it helps Google find new and updated pages faster
• Use lowercase paths — the Disallow directive is case-sensitive on most servers
• Add trailing slashes when blocking folders (e.g. Disallow: /admin/)

When to update your robots.txt file

Your robots.txt file should be reviewed whenever your site structure changes. Common triggers include:

• Launching a new site — make sure crawlers aren't locked out of key pages
• Setting up a staging environment — block it so it doesn't compete with your live site
• Site migration — update paths to match your new URL structure before redirects go live
• Identifying crawl waste in Google Search Console — block low-value parameter URLs or internal search pages
• Adding a new CMS or admin area — protect backend directories from being crawled

Tip — validate after every change

After uploading your updated robots.txt, test it in Google Search Console under Settings → robots.txt. GSC will flag any pages that are blocked but currently indexed.
