Robots.txt Generator.

When search engines visit your website, they use bots (also called spiders or crawlers) to index your content. But not everything on your website should be indexed.

That’s where the robots.txt file comes in.

It tells search engines what pages or folders to crawl — and what to skip. A Robots.txt Generator is a free tool that helps you create this file quickly and correctly, without needing to write it manually.

Let’s dive into what it is, how it works, and how to generate your own.

 

 What Is a Robots.txt File?

The robots.txt file is a plain-text file placed at the root of your website (e.g., yourdomain.com/robots.txt) that gives instructions to search engine bots about which parts of your site they’re allowed to crawl.

 

What Is a Robots.txt Generator?

A Robots.txt Generator is an online tool that helps you create a proper robots.txt file without coding. You simply select your preferences, and the tool generates the correct syntax.

✅ Benefits:

• Prevents indexing of sensitive/private pages (e.g., login pages, admin panels)
• Reduces server load by limiting unnecessary crawling
• Helps prioritize high-value pages for faster indexing

 

🧑‍💼 Real-Life Example: E-commerce Site Saves Crawl Budget

Site: An online fashion retailer with 50,000+ URLs

Issue: Googlebot was spending time crawling:

• Filtered pages like /category?color=blue
• Internal search results like /search?q=jeans

Action:
They used a robots.txt generator to:

• Disallow crawl of dynamic URLs
• Allow only primary categories and product pages

Result:

• 34% increase in crawl efficiency
• 17% faster indexing of new arrivals
• Better performance in Google Search Console
