Robots.txt Generator

1. Tool Overview

What This Tool Does

The Gotokit robots.txt generator is a browser-based, no-login, completely free visual rule builder for website crawling policies. It follows the RFC 9309 Robots Exclusion Protocol and is built for solo site owners, indie web projects, static blogs, ecommerce sites, and static site stacks such as Astro.

It helps you:

• select crawler User-agent values visually
• build crawl allow/block rules without writing syntax from scratch
• validate your file in real time
• copy or download a ready-to-deploy robots.txt
• switch between a visual editor and raw text mode

That makes it useful for both beginners who want safe defaults and advanced users who still prefer direct text editing.

Core Concepts You Should Know First

What robots.txt is

robots.txt is a plain text file placed in your site root, usually at:

https://your-domain.com/robots.txt

Its job is to tell compliant crawlers which areas of your site they are allowed to crawl and which areas they should avoid.

How the protocol works

When a major search engine crawler visits a site, it typically checks the root robots.txt file first. It then matches the crawler name (User-agent) and applies the relevant Allow and Disallow rules.

Important limitation:

• major search engines and legitimate SEO bots usually respect it
• malicious scrapers and abusive bots may ignore it completely

Crawling is not the same as indexing

• robots.txt controls crawling: whether a crawler can fetch the page
• noindex controls indexing: whether the page can appear in search results

If you need a page to stay out of search results entirely, you usually need noindex in page meta tags or an X-Robots-Tag HTTP header. Blocking a path in robots.txt alone is often not enough.

Local processing and privacy

All parsing, validation, and file generation happen in your browser. Your domain, crawler choices, and path rules are not uploaded to a server.

3. Full Interface Walkthrough

Module 1: Getting Started Area

• Title: 🤖 Robots.txt Generator
• Intro line: explains that Gotokit tools are free to use online with no signup or download

This section sets expectations clearly: no account, no usage cap, no paywall, no installation.

Module 2: Quick Template Presets

Templates are there to give you a practical starting point instead of a blank screen.

General Website Template

Best for:

• company websites
• content sites
• editorial or information sites

Typical default behavior:

• allows major search crawlers
• blocks obvious admin, private, or temporary paths like /admin/, /private/, and /tmp/
• leaves room for a sitemap URL

Static Blog / Tool Site Template

Best for:

• Astro sites
• VitePress or Hugo blogs
• online tool directories

Typical default behavior:

• allows public image and video crawlers
• blocks draft content under /draft/
• blocks preview pages under /preview/
• blocks internal endpoints such as /api/internal/
• avoids blocking public static assets under /assets/

Ecommerce Template

Best for:

• ecommerce stores
• DTC and cross-border shops
• catalog-based storefronts

Typical default behavior:

• blocks cart, checkout, account, and parameter-heavy pages
• keeps public product pages crawlable
• reduces duplicate crawl paths caused by filters and query variations
• leaves room for one or more sitemap entries

Block All Template

Best for:

• staging sites
• private demos
• pre-launch projects

Typical output:

User-agent: *
Disallow: /

This blocks crawling for the entire site. It is useful before launch, but it is not something you should leave on a live public site.

Module 3: Basic Site Settings

This section contains the two most important inputs: your website URL and your sitemap URL.

Website URL

Purpose:

• helps normalize your main domain
• helps autofill a sitemap URL
• does not get written directly into the final robots.txt body

Best practice:

• enter the full canonical site address
• use https, for example: https://demo.com

Sitemap URL

Purpose:

• writes one or more Sitemap: directives into the output file
• helps search engines discover your pages more efficiently

Formatting rules:

• use a full absolute URL, such as https://demo.com/sitemap.xml
• if you have multiple sitemaps, add them on separate lines
• if you leave it blank, the tool simply skips the Sitemap: lines

Module 4: Quick Global Switches

Allow All Crawlers

This creates a permissive default similar to:

User-agent: *
Disallow:

An empty Disallow means “do not block anything by default.” You can still add targeted blocks later.

Block All Crawlers

This creates a strict default:

User-agent: *
Disallow: /

That closes the entire site to compliant crawlers. If needed, you can later create additional rule groups for exceptions.

Module 5: Live Preview Actions

Copy Code

Copies the full robots.txt preview into your clipboard so you can paste it directly into a new file on your server.

Download robots.txt

Exports a correctly named robots.txt file locally, ready to upload to your site root.

Reset

Clears the current form, wipes the preview, and resets validation states so you can start over.

Module 6: Syntax Validation Panel

This area tells you whether the current configuration looks safe to deploy.

Valid Configuration

This usually means:

• no obvious duplicate User-agent groups
• no clear rule conflicts
• sitemap URLs are formatted correctly

Common warning and error scenarios

• duplicate crawler groups for the same User-agent
• invalid paths that do not start with /
• sitemap entries missing http or https
• conflicting rules, such as a broad Disallow paired with a more specific Allow

In compliant parsers, a more specific Allow can override a broader Disallow, but you should still review that logic carefully.

Module 7: Editing Modes

Visual Editing

This is the recommended mode for beginners. You can build rules by:

• choosing crawlers
• selecting Allow or Disallow
• entering paths

The preview updates automatically as you work.

Raw Text Mode

This is the advanced mode. You can write the full robots.txt file by hand, then let the tool validate it and, where possible, sync it back to the visual form.

It is useful for:

• large rule sets
• custom bots not included in the presets
• users who prefer direct text control

Module 8: Crawler and Path Rules

8.1 What a rule group means

Each rule group applies only to the User-agent values selected inside that group.

You can create multiple groups when different crawlers need different rules.

Example:

• Group 1: site-wide defaults for all crawlers
• Group 2: stricter blocks for AhrefsBot

8.2 Add Group and Duplicate Group

Add Group:

• creates a separate crawler rule block
• keeps different crawler strategies isolated

Duplicate Group:

• copies the current group, including selected crawlers and path rules
• saves time when you only need small edits

8.3 Preset crawler list

All Crawlers (*)

• maps to User-agent: *
• applies a rule set to every compliant crawler
• usually the best place to define site-wide defaults

Googlebot

• Google’s main web crawler
• fetches HTML content for Google Search
• usually worth allowing on public sites

Googlebot-Image

• Google’s image crawler
• used for Google Images
• usually relevant for blogs, media sites, galleries, and product pages

Googlebot-Video

• Google’s video crawler
• used for video pages and video indexing
• often unnecessary if your site has no video content

Bingbot

• Microsoft’s main crawler for Bing
• relevant for both global and Bing-based search visibility

DuckDuckBot

• crawler used by DuckDuckGo
• a smaller but still relevant traffic source in some markets

AhrefsBot

• Ahrefs SEO crawler
• used for backlink, page, and SEO analysis
• often blocked on smaller sites to reduce server load

SemrushBot

• Semrush crawler used for keyword and competitor analysis
• many site owners block it to reduce unnecessary crawling

YandexBot

• main crawler for Yandex
• important if your audience includes Russian-speaking or Eastern European markets

Baiduspider

• Baidu’s main crawler
• important for Chinese-language sites and Baidu search traffic

8.4 Custom User-agent

Use this when the crawler you need is not included in the preset list.

Examples:

• Applebot
• GPTBot
• CCBot
• facebookexternalhit

Typical use cases:

• Applebot: Apple search and Siri-related crawling
• GPTBot: OpenAI-related bot identifiers, often reviewed or blocked by content publishers
• CCBot: Common Crawl crawler

8.5 Path Rules Panel

Allow:

• explicitly allows crawling for a path
• often used when a parent path is blocked but a child path should stay crawlable

Disallow:

• explicitly blocks crawling for a path

Path entry rules:

• paths should start with /
• you can target directories or individual files

Examples:

• /admin/
• /private.html

Use Add Rule to attach that path rule to the current group. A single group can contain multiple Allow and Disallow entries.

8.6 Quick Paths and what they mean

/assets/

• common location for images, CSS, JavaScript, and fonts
• often left crawlable on public websites

/admin/

• admin and dashboard area
• often contains sensitive settings and should usually be blocked

/preview/

• preview or draft preview pages
• usually not useful for SEO and often better blocked

/tmp/

• temporary upload or cache directory
• not a good crawl target because contents are unstable

/api/internal/

• internal endpoints for your own system
• not meant for search engine access

/search/draft/

• draft or unpublished content area
• typically better kept out of crawl paths

/private/

• member-only, internal, or privacy-sensitive content
• usually better blocked from crawlers

4. Recommended Workflow

1. Start with the template closest to your site type
2. Enter your site URL and sitemap URL
3. Decide whether the default should be open or blocked
4. Build crawler-specific rule groups as needed
5. Review the live preview carefully
6. Check validation messages before deployment
7. Copy or download the file and place it in your site root

5. Important Notes

• the generated robots.txt content is language-neutral
• everything runs locally in your browser
• robots.txt affects crawling, not guaranteed removal from search results
