Robots.txt file works like a powerful rulebook, as it tells which pages on your site must be accessed and which ones should be ignored. So, understanding how Google and other crawlers move through their websites means you can think of better ideas that can improve your rankings and site performance.
Business owners planning to invest in SEO services must know about this file and how big its role is in keeping your SEO strategy effective. You can control anything with robots.txt, from blocking unnecessary pages to focusing on main content. Keep reading this guide, as it covers how this file works and how it can improve your site’s performance.

What is the Robots.txt File?
A robots.txt file is a small text file on a website’s server, which is placed to help web crawlers, like search engine bots. This file provides instructions to crawlers and tells them where they are allowed to go and which sections or pages they should ignore. This simply means that this file is a rulebook that tells Google and other bots which pages on a site they should crawl and which can be skipped. By properly managing this file, you can help bots access the most important content on your site and ignore low-value pages.
How a Robots.txt File Works?
Business owners use robots.txt files that make sure that the crawlers move through perfectly. This means you can make sure the crawlers only access valuable content on the site. So, you can prevent search engine bots from wasting time on pages that don’t appear in search results, like duplicate content. Before we move forward, let’s understand how robots.txt works:
1. Location
This file must always be placed in your website’s main root folder. Search engine bots first read this file before crawling other pages on your site. When it’s placed anywhere else and not in its exact location, it doesn’t work.
2. Instructions
This file contains simple rules that tell search engine bots which areas they can visit and which ones they should ignore on a site. You can use this file to prevent bots from crawling over duplicate content pages or block their access to test and block admin pages. With these simple allow and disallow commands, you can help Google decide what to crawl and what to ignore.
3. Purpose
The main work of this file is to help search engines, as it guides them on how they can crawl your site more effectively. This means bots don’t waste time on unnecessary pages that don’t have more valuable information. However, this file doesn’t provide protection against hackers and bad bots.
4. Security
This file is not a security tool and can’t be used to hide private or sensitive information. This can be accessed by anyone, and they can see which pages you are blocking. However, you can protect pages with very sensitive information by using noindex tags, passwords, and other security settings.
Robots.txt vs. Meta Robots vs. X-Robots: What’s the Difference?
All these three tools control how search engines should treat your content, so understanding their difference is a must. By knowing what they do and how they’re used for different parts of a website, you can choose the right option for any situation.
1. Robots.txt
As we discussed above, this is placed in a site’s root folder and gives instructions to search engine bots. It tells them which sections of the site they can crawl and which ones to ignore. So, this file works at a site-wide level and not for individual pages.
2. Meta Robots Tags
These are the snippets of the code and are placed inside the <head> sections of specific webpages. These are used to control whether a particular page should appear in search results and whether search engines should follow the links on it. So, this tool gives a page-level indexing control.
3. X-Robots-Tag
These are mainly used for non-HTML files, like videos, images, and PDFs. They are implemented in the HTTP header and help one to set indexing rules for files that cannot contain meta tags.
How to Control Search Engine Crawling with Robots.txt
A robots.txt file uses rules to tell search engine bots which pages or sections on a site they should avoid. This file helps you control crawling traffic and improve SEO performance. By properly using it, you can direct bots to important content or pages. You should also use this file to block access to pages with sensitive information, like admin pages and duplicate content. Here is how you can control search engine crawling using this file:
1. Create the File: You might think that creating a robots.txt file is difficult, but you need to follow some simple steps to create it. Firstly, you need to start by opening a basic text editor, like Notepad and save the file as robots.txt with UTF-8 format. Inside this file, you have to write short rules called directives that tell search engine bots what they can or can’t access.
2. User-Agent: This is the first directive, which tells which crawler the rules apply to, like Googlebot or Bingbot. However, when you want to apply the rule to every crawler, you simply need to add an asterisk (*). This will allow you to control how all bots interact with your site.
3. Disallow: Next, you use Disallow, which blocks crawlers from accessing specific pages or folders on your site. For example, you used this command: Disallow:/private/, this will stop search engine bots from entering the private folder.
4. Allow: This can be used to grant access to a specific file within a disallowed folder. For example, you use a command: Disallow:/forbidden-folder/ and Allow:/forbidden-folder/page.html. This will allow crawlers to access only one page of the disallowed folder. So, you can use disallow and allow together when you want to block a whole folder but allow a single file within it.
5. Sitemap: This must be added to help search engine crawlers to find your sitemap faster. This will help crawlers to understand your site’s structure. Once you’ve written all the rules, you need to save this file.
6. Upload the File: Finally, now you can upload your robots.txt file to the root directory of your site. By doing this, you will have the file available at yourdomain.com/robots.txt.
7. Set Permissions: You must make sure this file has correct permissions for search engines. Once you upload it, search engines will automatically detect and follow its instructions during crawling.
When to Use Robots.txt File
You should use a robots.txt file to tell search engines how their bots should interact with pages and content on your site. By properly using these, you can secure control of what must be crawled and what must be ignored.
- To Block Sensitive Areas: You can use this file to stop crawlers from accessing admin pages, login sections, or private folders on your site.
- To Manage Duplicate Content: You should use this file to stop crawlers from indexing duplicate pages. This will keep your SEO efforts effective.
- To Improve Crawling Efficiency: You must use robots.txt to tell search engines that they should block low-value pages. This will ensure they spend more time on the important pages. This makes it useful for websites with a large number of pages.
Key Concepts to Know About robots.txt
This plain text document placed in a site’s root directory tells search engine bots which pages they can or which ones they must ignore. So, their main purpose is to manage crawler traffic and not to hide private information. Here are some important points about it:
- This is not a security tool, as it only guides search engine bots to follow the rules. So, for true security, you should use strong password protection.
- This only prevents crawling and not indexing, which means even a blocked page can still be indexed. However, the description of the disallowed page will not appear in search results.
- Instead of a robots.txt file, you must use a noindex meta tag or HTTP header to fully hide or remove a page instead of robots.txt from search results.
- As this file is publicly accessible, which means anyone can view it, you must not use it to protect sensitive data. Instead, you should secure it through strong passwords and authentication methods.
Best Practices for Robots.txt File
You should know and follow the basic rules to make sure your robots.txt file gives you the desired results. A properly managed file will help search engines to crawl your site effectively without making any mistakes that can harm your SEO performance. Here are some of the best practices that you can use while controlling search engine crawling without accidentally blocking important content:
1. Correct File Location: You must make sure you always name the file exactly like robots.txt in all lowercase. You must place it in the root folder of your site. This will make sure search engines can easily find and read its instructions.
2. Don’t Block Essential Files: You should not block important files, like JS and CSS files, using it. These files help bots to understand how your pages look and function. However, when you accidentally block them, your pages might not appear in search results.
3. Use Testing Tools: You must check and test your robots.txt file often to make sure it works as you want. You can use tools, like GSC, to test your rules. This will help you ensure this file is not accidentally blocking pages with important content.
4. Use Correct Tools for the Job: When you want to manage crawling, you should use robots.txt. However, when you want to control what appears in search results, you should use noindex meta tags. You must never use a Disallow rule with a noindex tag on the same page, as crawlers need to access the page to see the noindex tag.
