Introduction to Robots.txt
If you want better control over how search engines crawl your website, understanding robots.txt is essential.
The robots.txt file is a simple but powerful part of technical SEO that tells search engine bots which pages they can access and which they should avoid.
In this guide, you will learn what robots.txt is, why it matters, and how to create and optimize a robots.txt file step by step.
What is Robots.txt?
Robots.txt is a text file placed in the root folder of your website that gives instructions to search engine crawlers.
In simple terms, robots.txt tells search engines:
- Which pages to crawl
- Which pages to block
Example URL:
👉 yourwebsite.com/robots.txt
This file is one of the first things search engine bots check when visiting your site.
Why is Robots.txt Important?
Robots.txt plays a key role in technical SEO by controlling how search engines interact with your website.
Benefits of robots.txt:
- Prevents crawling of unnecessary pages
- Saves crawl budget
- Protects sensitive areas (like admin pages)
- Helps search engines focus on important content
Without robots.txt, search engines may waste time crawling irrelevant pages.
How Robots.txt Works
When a search engine bot visits your website, it first looks for the robots.txt file.
It then follows the rules written inside the file.
Basic structure:
- User-agent → defines the bot
- Disallow → blocks access
- Allow → permits access
Basic Robots.txt Example
Here is a simple robots.txt file:
User-agent: *
Disallow: /admin/
Allow: /
Explanation:
- User-agent: * → applies to all bots
- Disallow: /admin/ → blocks admin section
- Allow: / → allows rest of the site
How to Create a Robots.txt File
Step 1: Open a Text Editor
Use Notepad or any code editor.
Step 2: Add Basic Rules
Start with simple rules like:
User-agent: *
Disallow:
This allows full access to your website.
Step 3: Save the File
Save the file as:
👉 robots.txt
Step 4: Upload to Root Directory
Upload it to your website root folder using:
- cPanel
- FTP
- File Manager
Final location:
👉 yourwebsite.com/robots.txt
Best Robots.txt Template (Recommended)
Use this optimized robots.txt template:
