Free Online Robots.txt Generator

Controlling how search engines crawl and index your website is an essential part of technical SEO.

Whether you’re a webmaster, SEO specialist, or developer, this tool helps ensure that search engines only crawl the pages you want them to, while keeping sensitive directories private.

What Is a Robots.txt File?

A robots.txt file is a simple text file that tells search engine crawlers (or "robots") which pages or sections of your website they can or cannot access. It acts as a set of rules for crawlers, defining which parts of your website are open for indexing and which are off-limits.

Placed in the root directory of your website (e.g., https://example.com/robots.txt), this file helps manage crawl budgets, prevent duplicate content issues, and improve website performance by guiding bots away from unnecessary pages.

Why Robots.txt Is Important

Many webmasters overlook the importance of robots.txt, but this small file can have a big impact on how search engines view your site. Here’s why it matters:

• Controls Crawling: Manage which pages or directories search engines can access.
• Protects Sensitive Data: Prevent crawlers from accessing admin panels or private content.
• Improves Crawl Budget: Ensure bots focus on your most important pages.
• Prevents Duplicate Content: Avoid indexing of duplicate or low-value pages.
• Optimizes Server Load: Reduce unnecessary bot requests.

Best Practices for Creating Robots.txt

• Always place the file in your root directory (e.g., https://example.com/robots.txt).

• Do not block essential pages like your homepage or product pages.
• Always include your sitemap URL for better crawling.
• Test your robots.txt file using the Google Search Console Robots Testing Tool.

Common Mistakes to Avoid

• Accidentally Blocking Entire Site: Avoid using “Disallow: /” unless you intend to stop all indexing.
• Using Wildcards Incorrectly: Misuse of “*” or “$” can lead to wrong exclusions.
• Incorrect File Location: Always upload robots.txt to the root, not a subdirectory.
• Overusing Crawl Delays: Excessive delays can reduce crawl frequency.
• Case Sensitivity Issues: URLs are case-sensitive; ensure accurate paths.

Testing Your Robots.txt File

Once generated, it’s important to test your robots.txt file to ensure search engines are following your directives properly. You can use:

• Google Search Console’s Robots.txt Tester
• Bing Webmaster Tools
• Online testing tools that simulate how bots read your file

Advanced Tips for Developers

• Use separate robots.txt files for subdomains (e.g., blog.example.com/robots.txt).
• Combine “Allow” and “Disallow” strategically to refine crawl behavior.
• Monitor crawl logs to ensure bots are following your directives.
• Integrate your sitemap dynamically if your site content changes often.

Understanding User Agents

Different search engines and platforms use unique user agents. Here are some examples:

• Google: Googlebot
• Bing: Bingbot
• Yahoo: Slurp
• DuckDuckGo: DuckDuckBot
• Yandex: YandexBot
• Baidu: Baiduspider

How Robots.txt Impacts SEO

While robots.txt doesn’t directly affect rankings, it influences how efficiently your website is crawled and indexed. By blocking unnecessary or duplicate pages, you help search engines prioritize high-quality content, indirectly improving your SEO performance.

Robots.txt vs Meta Robots Tag

• Robots.txt: Controls which URLs bots can access.
