What is Robot.txt File?

Robots.txt is a text file that you put on your website root directory (eg. www.domain.com/robots.txt). This text file is always named “robots.txt” and it follows a strict syntax. It’s also very important that your robots.txt file is really called “robots.txt” as this name is case sensitive. Make sure you name the file correctly or it will just now work for you.

Functionally, this file is the opposite of your sitemap. A site map exists to tell search engines what pages you want them to index and, a robots file does the opposite – it tells them what pages you don’t want them to index.

In this file, you specify which parts of your website should be crawled by spiders or web crawlers. You can specify different rules for different spiders/bots in Robots.txt file. Remember that it is by no means compulsory for search engines but generally, search engines obey what they are asked not to do.

Googlebot is an example of a spider. It’s deployed by Google to crawl the Internet and record information about websites so it knows how high to rank different websites in search results.

Why do you need Robot.txt file?

To explain you why do you need Robots.txt on your website, I will start from basics. First of all, you may be wondering – what are bots? Bots are search engine Robots or Spiders. They are designed to crawl a website and all the search engines have their own bots to do this activity. There are two key terms here that you should understand i.e. Crawling and Indexing. These are two different terms. On a high level, Crawling is following a path (links). For a website, crawling means following the web links. Indexing means adding those web links to the search engine. Indexing also depends on the meta tag which you use for your web pages (Meta tags – Index or noIndex).

Now, when a search engine bot (Google bot, Bing bot, or any search engine crawlers) comes to your site following a link or following your sitemap link that you have submitted to the webmaster search console, they follow all the links on your website to crawl and index your site.

How Bots/Crawlers Work –

When a search engine bots come on your website, they have limited resources to crawl your site. If they can’t crawl all the web pages on your website in given resources, they stop crawling, and this can hamper website indexing.  It’s great if search engine completes indexing but there are many parts of the website which you want to protect from crawlers or bots. For example, the wp-admin folder, the admin dashboard or other pages, which are not useful for search engines. Using robots.txt, you can direct search engine crawlers (bots), to not to crawl such area of your website. This way you will not only speed up crawling of your website but will also help you in deep crawling of your inner pages.

Do remember that Robots.txt file is not for Index or Noindex but it’s just to direct search engine bots to stop crawling certain part of your blog. For example, if you look at the DigitalHarpreet robots.txt file, you will definitely understand, what part of my blog I don’t want search engine bots to crawl.

How to Access Robot.txt file?

Robot.txt file is located in the root directory of your website. In order to edit or view it, go to you c-panel and locate your file manager and then go to the public_html folder or you can connect your website to an FTP client to access it.

Robots.txt File Locate in Cpanel

It is just like any normal text file, and you can open it with a plain text editor like Notepad. If you do not have a robots.txt file in your site’s root directory, then you can always create one. All you need to do is create a new text file on your computer and save it as robots.txt. Next, simply upload it to your site’s root folder.

Robots.txt file syntax

Here is an Example Robots.txt File.

Where,

User-agent: * → The first line is defining the rules which should be followed by all web crawlers. Here asterisk means all spiders in this context.

Disallow: /ebooks/*.pdf → In connection with the first line, this link means that all web crawlers should not crawl any pdf files in the ebooks folder within this website. This means search engines won’t include these direct PDF links in search results.

Disallow: /staging/ → In connection with the first line, this line asks all crawlers not to crawl anything in the staging folder of the website. This can be helpful if you’re running a test and don’t want the staged content to appear in search results.

User-agent: Googlebot-Image — This explains that the rules that follow should only be followed by just one specific crawler i.e. the Google Image crawler. Each spider uses a different “user-agent” name.

Disallow: /images/ — In connection with the line immediately above this one, this asks the Google Images crawler not to crawl any images in the images folder.

How to optimize WordPress robots.txt file SEO?

Robots.txt file helps you to safeguard your things from web crawlers/bots if coded correctly but if you configure it incorrectly then it could harm your web presence go away completely. So, it is highly recommended to follow extra caution when you make changes in this file.

At this point, I am assuming that you are reading this article from the top and you already know how to access you robots.txt file. If you don’t have robots.txt on your site then you can create a new one using Notepad (.txt file). While you create that file, make sure you name it correctly i.e. robots.txt and then FTP that file to the root of your website. If you are not using FTP client then go your c-panel and locate File manager and then upload your file to the root directory (public_html).

Once you have located your Robots.txt file, its time to write something to it. Now before you write into this file, the question is –What you want your Robots.txt file to do for you?

There are three ways you can code your Robots.txt file –

  1. Code it to Allow Everything – All content can be crawled by the bots.
  2. Code it to Disallow Everything – No content can be crawled by the bots.
  3. Code it to Conditional Allow few things– Directions written in the robots.txt file will determine what content to crawl and what not.

Let’s see how to code above three options in Robots.txt –

Allow Everything – All content can be crawled by the bots –

Most people want robots to visit everything on their website. If this is the case with you, and you want the robot to index all parts of your site then there are three ways to achieve this –

  1. Do not have a Robots.txt at all on the website.
  2. Make an empty Robots.txt file and add it to the root of your website.
  3. Make a robots.txt file and write the following code in it.

         If your website has a robots.txt with these instructions in it then this is what happens. A robot e.g. Googlebot comes            to visit. It looks for the robots.txt file. It finds the file and reads it. It reads the first line. Then it reads the second line.          The robot then feels free to visit all your web pages and content because this is what you told it to do.

Disallow Everything – No content can be crawled by the bots –

Warning – By doing this, you mean that Google and other search engines will not index your web pages.

To block all the search engine crawlers from your website, you need to add following lines to your robots.txt file –

Conditional Allow – Directions written in the robots.txt file will determine what content to crawl and what not.

Here is the sample robot.txt file for WordPress with conditional allow/disallow statements.

***Important Robots.txt coding guidelines –

  1. Don’t use comments in Robots.txt file.
  1. Make sure you don’t add any spaces in the beginning of your directives. For example,

  1. Don’t change the order of commands. For example,

  1. If you want to disallow multiple directories then write below lines in robots.txt,

Instead of writing then all together like this –

  1. Use capital and small letters carefully. For example, if you want to disallow “readme.html” but if you write it as “Readme.html” then it will confuse search engine bot and eventually you will get the desired result.
  1. Avoid logical errors. For example –

The above example is from a robots.txt that allows all agents to access everything on the site except the /temp directory. Up to here, it is fine but later on, there is another record that specifies more restrictive terms for Googlebot. When Googlebot starts reading robots.txt, it will see that all user agents (including Googlebot itself) are allowed to all folders except /temp/. This is enough for Googlebot to know, so it will not read the file to the end and will index everything except /temp/ – including /images/ and /cgi-bin/, which you think you have told it not to touch. You see, the structure of a robots.txt file is simple but still serious mistakes can be made easily.

How to Add XML Sitemap to Robots.txt file?

You can achieve this adding below lines to robots.txt. You can replace the below sitemap links with your own website sitemap.xml.
