Quick answer: Robots.txt Generator
Draft Allow/Disallow groups per user-agent plus optional sitemap declarations for crawler hints.
Example: User-agent * disallow /admin/ and /api/private/ while allowing /blog/; sitemap https://example.com/sitemap.xml appended.
Calculations follow the documented formula on this page; rounding and input units can change the last digit—treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
What this calculator does
- Robots.txt Generator
- Draft robots.txt rules with allow/disallow paths and sitemap lines.
Robots.txt is cooperative, not secure - sensitive routes should be auth-gated, not merely disallowed.
Generate a robots.txt file for standard crawlers with multiple Allow/Disallow lines and an optional sitemap URL.
Inputs on this page: User-agent, Allow Paths (one per line), Disallow Paths (one per line), Sitemap URL (optional). Assumptions stay visible so you can reproduce the figure elsewhere.
When to use it
- Use Robots.txt Generator when you need a transparent robots.txt generator answer before you commit numbers to a spreadsheet, invoice, or conversation.
- Reach for it when you already know (or can estimate) User-agent and want the dependent result without rebuilding the formula by hand.
- Skip it when you need certified advice, signed-off payroll, or a lender’s official quote—those require the primary institution’s systems.
Key takeaways
- Wildcards and crawl-delay aren’t honored uniformly - test in GSC.
- Staging hosts need their own robots rules before accidental indexing.
- Don’t block CSS/JS needed for rendering if you care about modern SEO.
How to use this tool
- 1Set the user-agent group (often * for all bots).
- 2List allow and disallow paths, one per line.
- 3Add your canonical sitemap URL if available.
- 4Upload to site root as robots.txt and verify in search consoles.
