What it generates

Create crawler rules with built-in safety checks.

Use Wranker to structure crawler directives, add sitemap discovery and review common robots.txt risks before upload.

Use it during internal linking audits, content optimisation, technical SEO reviews, website migrations and content hub planning.

Rules

Structured crawler directives

Build Allow and Disallow rows for all crawlers, selected search bots or custom user-agents without writing every directive manually.

Sitemap

Sitemap discovery built in

Add your XML sitemap URL or use the suggested sitemap path based on the normalised site origin so crawlers can discover it from robots.txt.

Safety

Risky-block warning review

Review patterns like Disallow: /, blocked sitemap paths, blocked assets, duplicate rules and conflicting Allow or Disallow instructions.

Export

Ready-to-upload file flow

Prepare a clean robots.txt file for copy or download, with validation and raw data handoff available in the results workflow.

Why it matters

Robots.txt can protect crawl budget or block the wrong pages.

A robots.txt file does not directly improve rankings, but it can help manage crawl access, reduce crawler waste and point bots to your XML sitemap. Broad or incorrect rules can prevent search engines from accessing important content.

Reduce manual syntax errors

Use structured inputs for user-agent, directive and path fields so implementation is faster and less error-prone.

Avoid accidental crawl blocks

Spot broad or sensitive rules before upload, especially full-site blocks and important folders such as blog, images, assets or sitemap paths.

Support technical SEO workflows

Use generated robots.txt files alongside sitemap validation, crawlability checks, indexability reviews and project-level reporting.

How it works

From site URL to review-ready rules.

The public landing-page workflow stays focused on setup. Generated file previews and exports open after submission.

01

Enter your site URL

Add the website where the robots.txt file will be used. Page URLs are normalised to the domain origin because robots.txt belongs at the root.

02

Add your sitemap URL

Include the XML sitemap location or use the suggested sitemap URL based on the site origin, then edit or remove it as needed.

03

Choose bots and build rules

Select all crawlers or specific bots, then add structured Allow and Disallow paths with optional internal notes.

04

Review warnings and generate

Submit the setup to open the generated file, rule preview, validation checks and copy or download actions in the output workflow.

Who should use it

Practical robots.txt workflows for SEO and implementation teams.

Use it for new websites, staging clean-up, crawler control, technical SEO implementation and sitemap discovery.

SEO beginners

Create a basic robots.txt file without memorising syntax, then review warning guidance before upload.

Technical SEO specialists

Build crawler-control rules quickly during audits, migrations, staging clean-ups and implementation checks.

Agencies

Prepare client-ready robots.txt files and connect the next steps to sitemap validation and broader technical SEO reporting.

Developers and site owners

Generate a structured file for the site root, add sitemap discovery and keep sensitive internal paths out of crawler access.

FAQs

Questions about robots.txt generation.

Clear answers for creating, reviewing, downloading and uploading a robots.txt file safely.

A robots.txt generator is a tool that helps you create a robots.txt file using structured inputs such as user-agent, Allow rules, Disallow rules and sitemap URL.

A robots.txt file is a text file placed at the root of a website. It gives crawler access instructions to search engines and other bots.

Upload the file to the root of your website, such as https://www.example.com/robots.txt.

Yes. If you use a rule such as User-agent: Googlebot and Disallow: /, Googlebot may be blocked from crawling the whole site. Always review critical warnings before uploading.

Yes, adding a Sitemap line is recommended because it helps crawlers discover your XML sitemap.

Yes. You can create rules for all crawlers using * or selected bots such as Googlebot, Bingbot, AhrefsBot, SemrushBot, GPTBot or a custom user-agent.

Disallow tells the selected crawler not to crawl a specific path. For example, Disallow: /admin/ asks crawlers not to access the admin directory.

Allow tells the selected crawler that a specific path may be crawled. It is often used when a broader rule blocks a directory but a specific subpath should remain accessible.

Yes. After generating the file, you can copy the output or use Download robots.txt to download the file.

No. Robots.txt controls crawling, not guaranteed removal from search results. For index control, review noindex tags, canonical tags, URL removal tools and indexability settings.
