The robots.txt file is an essential part of your website’s SEO strategy, guiding search engine crawlers on how to index your site. Sometimes, you might need to manually overwrite this file in WordPress to customize how search engines interact with your site.
The robots.txt file instructs search engines about which pages or sections of your website should be crawled or ignored. While WordPress automatically generates a default robots.txt file if one does not exist, there might be times when you need to manually create or modify this file to better control search engine behavior. This process involves direct interaction with your website’s file system, which can be done through various methods such as FTP, cPanel, or file management plugins.

Methods to Manually Overwrite the robots.txt File
1. Using FTP or File Manager
Step 1: Access Your Website’s File System
- FTP: Use an FTP client like FileZilla to connect to your website’s server. You’ll need your FTP credentials from your hosting provider.
- cPanel File Manager: Log in to your hosting provider’s cPanel and navigate to the File Manager.
Step 2: Locate the robots.txt File
- Navigate to the root directory of your WordPress installation, which is usually the public_html folder.
Step 3: Download and Edit the File
- If a robots.txt file exists: Download the file to your local computer, open it with a text editor (like Notepad or Sublime Text), and make the necessary changes.
- If the file does not exist: You can create a new robots.txt file using a text editor.
Step 4: Upload the Updated File
-
- FTP: Drag and drop the modified robots.txt file into the root directory, overwriting the existing file.
- cPanel: Upload the new file to the root directory and confirm that it replaces any existing file.
2. Using a WordPress Plugin
Step 1: Install a Robots.txt Plugin
- Navigate to the WordPress admin dashboard, Plugins >> Add New, and search for a plugin like Yoast SEO or All in One SEO. These plugins have built-in functionality for managing robots.txt.
Step 2: Configure the Plugin
- After installing and activating the plugin, go to its settings. Look for a section related to robots.txt or SEO tools.
Step 3: Edit the robots.txt File
-
- Use the plugin’s interface to create or modify the robots.txt rules as needed. This method provides a user-friendly way to manage your file without direct file system access.
3. Creating a robots.txt File Through WordPress Functions
Step 1: Use a Function in Your Theme’s functions.php
- Add custom code to your theme’s functions.php file to control the robots.txt file. Here’s a basic example:
add_action('do_robotstxt', 'custom_robots_txt');
function custom_robots_txt() {
echo "User-agent: *\n";
echo "Disallow: /private/\n";
echo "Allow: /public/\n";
}Step 2: Save Changes
-
- Update the functions.php file with the custom code and save your changes. This method is less common and should be used with caution as it involves PHP code editing.
Manually overwriting the robots.txt file in WordPress allows you to have finer control over how search engines interact with your site. Whether you choose to edit the file directly via FTP or cPanel, use a WordPress plugin, or create it through PHP code, it’s essential to ensure your rules are correctly set to optimize search engine visibility and protect sensitive parts of your site. Regularly reviewing and updating your robots.txt file as needed will help maintain effective search engine optimization and improve your site’s performance in search results.
