How to Easily Edit a Robots.txt File in WordPress (Step by Step)

Would you like to know how to edit robots.txt files in WordPress?

A robots.txt file is a powerful SEO tool since it works as a website guide for search engine crawl bots or robots. Telling bots not to crawl unnecessary pages can improve your site's load speed and rankings in search engines.

In this post, we'll show you step-by-step instructions on how to edit your robots.txt file in WordPress. We'll also cover what a robots.txt file is and why it's important.

What Is a Robots.txt File?

A robots.txt file tells search engines how to crawl your site — where they're allowed to go or not.

Search engines like Google use these web crawlers, sometimes called web robots, to archive and categorize websites.

Most bots are configured to search for a robots.txt file on the server before it reads any other file from your site. It does this to see if you've added special instructions on how to crawl and index your site.

The robots.txt file is typically stored in the root directory, also known as the main folder of your website.

The URL can look like this:

http://www.example.com/robots.txt

To check the robots.txt file for your own website, you simply replace http://www.example.com/ with your domain and add robots.txt at the end.

Now, let's take a look at what the basic format for a robots.txt file looks like: 

User-agent: [user-agent name]
Disallow: [URL string not to be crawled]
 
User-agent: [user-agent name]
Allow: [URL string to be crawled]
 
Sitemap: [URL of your XML Sitemap]

User-agent refers to the search engine bot or robot you want to block or allow to crawl your site (for example, the Googlebot crawler).

When editing your robots.txt file, you can include multiple instructions to either Allow or Disallow specific URLs, plus add multiple sitemaps. You can also exclude URL parameters using the Clean-param directive and set the frequency of visits by search bots using the Crawl-delay directive.

Default Robots.txt File in WordPress

By default, WordPress automatically creates a robots.txt file for your site. So, even if you don’t lift a finger, your site should already have the default WordPress robots.txt file.

But when you later customize it with your own rules, the default content is replaced. 

Here’s how the default WordPress robots.txt file looks:

User-agent: *
Disallow: /wp-admin/
Allow: /wp-admin/admin-ajax.php

The asterisk after User-agent: * means that the robots.txt file is for all web robots that visit your site. As mentioned, the Disallow: /wp-admin/ tells robots not to visit your wp-admin page.

You can test your robots.txt file by adding /robots.txt at the end of your domain name. For example, if you enter “https://ml.aioseo.com/es/robots.txt” in your web browser, it shows the robots.txt file for AIOSEO:

Now that you know what a robots.txt file is and how it works, let’s look at why the robots.txt file matters in the first place.

Why Is the Robots.txt File Important?

The robots.txt file is important if you want to:

• Optimize Your Site Load Speed — by telling bots not to waste time on pages you don’t want them to crawl and index, you can free up resources and increase your site load speed.
• Optimizing Your Server Usage — blocking bots that are wasting resources will clean up your server and reduce 404 errors.

When to Use the Meta Noindex Tag Instead of Robots.txt

If your primary goal is to stop certain pages from being included in search engine results, using a noindex meta tag is the proper approach.

This is because the robots.txt is not directly telling search engines not to index content – it’s just telling them not to crawl it.

In other words, you can use robots.txt to add specific rules for how search engines and other bots interact with your site, but it won’t explicitly control whether your content is indexed or not.

With that said, let’s show you how to easily edit your robots.txt file in WordPress step by step using AIOSEO.

Editing Your Robots.txt in WordPress Using AIOSEO

The easiest way to edit the robots.txt file is to use the best WordPress SEO plugin, All in One SEO (AIOSEO).

AIOSEO is a powerful yet easy-to-use SEO plugin that boasts over 3 million users. That means millions of smart bloggers use AIOSEO to help them boost their search engine rankings and drive qualified traffic to their blogs. That’s because the plugin has many powerful features and modules designed to help you properly configure your SEO settings. Examples include:

• Next-gen Schema generator: This no-code schema generator enables users to generate and output any schema markup on your site.

One reason users love the plugin is that it gives you greater control over how search engines crawl your site. This is thanks to the advanced robots.txt editor that allows you to easily configure your robots.txt file, enabling you to override the default WordPress file.

So, let's get to editing your robots.txt file.

To Edit Your Robots.txt File, First Enable Custom Robots.txt

To edit your robots.txt file, click Tools in the All in One SEO menu, then click on the Robots.txt Editor tab.

AIOSEO will then generate a dynamic robots.txt file. Its content is stored in your WordPress database and can be viewed in your web browser, as we'll show you in a bit.

Once you've entered the Robots.txt Editor, you need to Enable Custom Robots.txt. 

Click on the button so it turns blue.

You’ll then see the Robots.txt Preview section at the bottom of the screen, which shows the WordPress default rules that you can overwrite with your own. The default rules tell robots not to crawl your core WordPress files (admin pages).

Now, let’s move on to adding your own rules. You can do it in one of 2 ways: using the rule builder or importing a robots.txt file from another site.

Method 1: Add Rules Using the Rule Builder

The rule builder is used to add your own custom rules for what pages the robots should crawl or not.

For instance, you can use the rule builder if you'd like to add a rule that blocks all robots from a temporary directory.

To add a custom rule, enter the User Agent (for example, Googlebot crawler) in the User Agent field. Or you can use the * symbol to apply your rule to all user agents (robots). 

Next, select one of the preset robots.txt directives: Allow, Disallow, Clean-param, or Crawl-delay.

You can also add more directives by clicking on the Add Rule button.

After you've decided on the directive to apply, you need to enter the directory path or filename in the Value field.

Once this is done, you can go ahead and click the Save Changes button in the bottom right corner of the page.

When you’ve saved your new rules, they'll appear in the Robots.txt Preview section.

To view your robots.txt file, click the Open Robots.txt button.

This will take you to the URL where your robot.txt is hosted.

Method 2: Import Rules from Another Site

Another easy way of adding directives in your robots.txt is to import them from another site. This function is handy if you've created a site or know of one with a robots.txt file you'd like to replicate.

To import a robots.txt file from another site, go to the AIOSEO menu, then Tools » Robots.txt » Enable Custom Robots.txt.

Next, click the Import option.

This will open a window where you can paste the URL of the site you want to pull the robots.txt file from.

Click Import, and you'll be prompted to reload your site. Reload, and the plugin will pull the robots.txt file and implement it on your site.

Alternatively, you can copy the robots.txt file from your target site and paste it into the provided space. Again, click Import, and the robots.txt file will be added to your site.

This is probably the easiest way to add a custom robots.txt file to your WordPress site.

Editing the Robots.txt Rules Using the Rule Builder

To edit your robots.txt rules, you can change the details in the rule builder.

You can also delete a rule in the robots.txt file by clicking the trash can icon to the right of the rule.

And that's not all! AIOSEO's robots.txt editor allows you to move rules up or down to place them in order of priority. To do that, click on and hold the 6 dots next to the trash can to drag and reposition a rule.

Once you're done editing your robots.txt, click the Save Changes button to save your new rules.

As simple as that!

You've edited your robots.txt file.
