Understanding the Robots.txt File
A robots.txt file is a simple text document that website owners use to instruct search engine bots on how to crawl and index their web pages.
This file is usually located in the root directory, which is the main folder of your website. The standard format for a robots.txt file is as follows:
User-agent: [name of the user-agent]
Disallow: [URL that should not be crawled] User-agent: [name of the user-agent]
Allow: [URL that can be crawled] Sitemap: [link to your XML Sitemap]
You can include multiple lines of instructions to specify which URLs should be allowed or disallowed, as well as include several sitemaps. If a URL is not disallowed, search engine bots will assume they are permitted to crawl it.
Here’s an example of what a robots.txt file might look like:
User-Agent: *
Allow: /wp-content/uploads/
Disallow: /wp-content/plugins/
Disallow: /wp-admin/
Sitemap: https://example.com/sitemap_index.xml
In this example of a robots.txt file, we have permitted search engines to crawl and index the files in our WordPress uploads directory.
Additionally, we have restricted search bots from crawling and indexing the plugins and WordPress admin directories.
Finally, we have included the link to our XML sitemap.
Is a Robots.txt File Necessary for Your WordPress Site?
Although your website can operate without a robots.txt file, our experience shows that sites with well-optimized robots.txt files achieve better rankings in search results.
From our collaborations with clients in diverse industries, we’ve observed that effectively managing crawl budgets with robots.txt can accelerate the indexing of crucial content and enhance overall SEO performance.
This may not significantly affect you when you first launch a blog with minimal content.
However, as your website expands and you add more content, you will likely want greater control over how your site is crawled and indexed.
Here’s why this is important.
Search engines assign what Google refers to as a ‘crawl budget’ to each website, which determines the number of pages they will crawl within a specified period.
Our analysis of thousands of WordPress sites indicates that larger websites particularly benefit from optimizing this crawl budget through careful configuration of the robots.txt file.
For instance, one of our enterprise clients experienced a 40% increase in crawl efficiency after applying our suggested robots.txt optimizations.
You can prevent search bots from crawling unnecessary pages, such as your WordPress admin area, plugin files, and themes directory.
By blocking unnecessary pages, you conserve your crawl budget. This allows search engines to explore more pages on your site and index them more efficiently.
Another important reason to implement a robots.txt file is to prevent search engines from indexing specific posts or pages on your website.
However, it’s crucial to understand that robots.txt is not the most effective method for hiding content. A disallowed page can still show up in search results if it is linked from other websites.
If you want to ensure a page does not appear on Google, you should use a ‘noindex’ meta tag instead. This instructs search engines not to include the page in their index at all.
What Should an Ideal Robots.txt File Include?
Many well-known blogs utilize a straightforward robots.txt file. The content may differ based on the specific needs of each site:
User-agent: *
Disallow:
Sitemap: https://www.example.com/post-sitemap.xml
Sitemap: https://www.example.com/page-sitemap.xml
This robots.txt file permits all bots to index all content and provides links to the website’s XML sitemaps.
For WordPress websites, we suggest including the following guidelines in the robots.txt file:
User-Agent: *
Allow: /wp-content/uploads/
Disallow: /wp-admin/
Disallow: /readme.html
Disallow: /refer/
Sitemap: https://www.example.com/post-sitemap.xml
Sitemap: https://www.example.com/page-sitemap.xml
This instructs search engines to index all your WordPress images and uploaded files by specifically using the Allow directive, which is a useful command recognized by search engines like Google.
It then prevents search engines from indexing the WordPress admin area, the default readme.html file (which may disclose your WordPress version), and common directories for hidden affiliate links such as /refer/.
By including sitemaps in the robots.txt file, you facilitate easier access for Google bots to discover all the pages on your website.
Now that you understand what an optimal robots.txt file looks like, let’s explore how to create a robots.txt file in WordPress.
How to Create a Robots.txt File in WordPress
There are two methods to create a robots.txt file in WordPress. You can select the method that suits you best.
Method 1: Editing the Robots.txt File Using All in One SEO
All in One SEO, commonly referred to as AIOSEO, is the leading SEO plugin for WordPress, trusted by more than 3 million websites. It is user-friendly and includes a built-in robots.txt file generator.
For more information, check out our comprehensive AIOSEO review.
If you haven’t installed the AIOSEO plugin yet, follow our step-by-step guide on how to install a WordPress plugin.
Important: A free version of AIOSEO is available and includes this feature.
After installing and activating the plugin, you can easily create and modify your robots.txt file directly from the WordPress admin dashboard.
Just navigate to All in One SEO » Tools to access the robots.txt file editor.
First, enable the editing option by toggling the ‘Enable Custom Robots.txt’ switch to blue.
With this option enabled, you can create a personalized robots.txt file in WordPress.
All in One SEO will display your current robots.txt file in the ‘Robots.txt Preview’ section at the bottom of your screen.
This preview will show the default rules that WordPress has set.
These default rules instruct search engines not to crawl your essential WordPress files, allow bots to index all content, and provide a link to your site’s XML sitemaps.
You can now create custom rules to enhance your robots.txt file for better SEO.
To create a rule, input a user agent in the ‘User Agent’ field. Using an asterisk (*) will apply the rule to all user agents.
Next, choose whether you want to ‘Allow’ or ‘Disallow’ search engines from crawling your site.
Then, specify the filename or directory path in the ‘Directory Path’ field.
The rule will be automatically added to your robots.txt file. To create another rule, simply click the ‘Add Rule’ button.
We suggest adding rules until you achieve the optimal robots.txt format we discussed earlier.
Your custom rules will appear like this.
Once you have finished, remember to click the ‘Save Changes’ button to save your updates.
Method 2: Editing the Robots.txt File with WPCode
WPCode is a versatile code snippets plugin that allows you to add custom code to your website easily and securely.
It also features a convenient option for quickly editing the robots.txt file.
Note: There is a WPCode Free Plugin available, but it does not include the file editor functionality.
First, you need to install the WPCode plugin. For detailed instructions, refer to our beginner’s guide on installing a WordPress plugin.
After activation, you will need to go to the WPCode » File EditorNavigate to the page and click on the ‘robots.txt’ tab to begin editing the file.
You can now paste or enter the desired content for your robots.txt file.
Once you have completed your edits, be sure to click the ‘Save Changes’ button at the bottom of the page to apply your updates.
Method 3: Manually Editing the Robots.txt File Using FTP
This method requires an FTP client to modify the robots.txt file. Alternatively, you can utilize the file manager provided by your WordPress hosting service.
Pro Tip:Before making any changes, we suggest downloading a backup of your existing robots.txt file (if available) to your computer. This way, you can easily restore it if needed.
Connect to your WordPress site using an FTP client.
Once connected, you will find the robots.txt file located in the root folder of your website.
If the file is not present, it means you do not currently have a robots.txt file.
In that case, feel free to create a new one.
The robots.txt file is a plain text document, allowing you to download it and edit it with any basic text editor, such as Notepad or TextEdit.
After making your changes, upload the updated robots.txt file back to the root folder of your website.
How to Validate Your Robots.txt File
After creating or modifying your robots.txt file, it’s essential to verify it for any errors. A minor mistake could unintentionally block crucial pages from being indexed by search engines, making this step vital! 👍
Previously, Google had a specific testing tool, but this functionality has now been incorporated into the main Google Search Console reports.
First, ensure your website is linked to Google Search Console. If you haven’t done this yet, follow our straightforward guide on adding your WordPress site to Google Search Console.
Once you’ve set everything up, access your Google Search Console dashboard. Navigate to Settings located in the bottom-left menu.
Next, locate the ‘Crawling’ section and click ‘Open Report’ next to ‘robots.txt’.
Simply select the current version of the file from the list.
This report will display the latest version of your robots.txt file that Google has detected. It will point out any syntax errors or logical issues it has identified.
Don’t be concerned if you recently updated your file and the changes aren’t visible immediately. Google checks for a new version of your robots.txt file approximately once a day.
You can revisit this report later to verify that Google has acknowledged your recent updates and that everything appears to be in order.
Concluding Remarks
The primary aim of fine-tuning your robots.txt file is to prevent search engines from accessing pages that are not meant for public viewing, such as those in your wp-plugins directory or within your WordPress admin area.
A widespread misconception among SEO professionals is that blocking WordPress categories, tags, and archive pages will enhance crawl efficiency, leading to quicker indexing and improved rankings.
This belief is incorrect. In reality, Google strongly advises against this approach, as it contradicts their best practices for helping them understand your website.
We suggest adhering to the recommended robots.txt format to develop an effective robots.txt file for your site.
Common Questions About WordPress Robots.txt
