Unlocking the Power of Robots.txt for SEO: A Comprehensive Guide

As a business owner, you should understand the importance of optimising your websites for search engines. Various strategies can be employed to improve a website’s ranking on search engine result pages (SERPs) and one such strategy is the use of Robots.txt.

What is Robots.txt?

Robots.txt is a file that tells search engine crawlers which pages or sections of a website to crawl or not to crawl. It is a crucial component of your website, as it provides instructions to search engine crawlers on which URLs, they should avoid crawling. To optimise your website’s technical SEO and perform an SEO audit, it’s essential to have a solid understanding of what the robots.txt file is, how it functions, how to give instructions to crawlers and how to validate the effectiveness of those instructions.

Where Is It Located?

Robots.txt generator is a simple text file located in the root directory of your website that provides instructions to search engine crawlers about which pages to crawl. The robot’s exclusion standard is used to determine the validity of these instructions. The User-Agent and Disallow directives work together to tell crawlers which URLs to prevent from being crawled. If your robots.txt file only contains “User-Agent: * Disallow: /,” then your entire website will be prevented from being crawled.

How Does Robots.txt Works?

Robots.txt works by telling search engine crawlers which pages or sections of a website they can access and index. The file contains instructions in the form of rules that are written in a specific syntax. When a search engine crawler visits a website, it looks for the robots.txt file in the root directory of the website. If the file is present, the crawler reads the instructions contained in it and follows them accordingly.

Importance of Robots.txt for SEO

Robots.txt is important for small business SEO as it helps-

Control how search engine crawlers interact with a website. By specifying which pages or sections of a website search engine crawlers can access, website owners can ensure that only relevant pages are crawled and indexed
Improve the website’s visibility on search engine result pages by ensuring that only high-quality pages are indexed

Prevent search engine crawlers from accessing duplicate content, website owners can avoid penalties that may arise from having duplicate content on their websites. This is important because having duplicate content on a website can negatively impact its visibility on search engine result pages.

There is a common misconception that blocking a page in the txt file will prevent it from being indexed by search engines. However, this is not entirely true. Even if a page is blocked in robots.txt, it can still appear in search results, albeit without a detailed snippet.
Pages can still get indexed if they are included in the sitemap.xml, have internal or external links pointing to them, or if other signals indicate their relevance.
To reliably block pages from being indexed, it is better to use the No index directive instead. This can be done using a meta tag or an HTTP response header, which instructs search engine crawlers to remove the page from the index completely.
To prevent legitimate search engine crawlers from indexing your pages, you can use a no-index meta tag in the header of your page or an HTTP response header. Although some malicious bots and crawlers may ignore these directives, most legitimate ones will respect them.

To block all robots from indexing your pages, you can use the following code in the header of your page. For a more advanced approach, you can configure an Apache server to return your pages’ HTTP response by placing the X-Robots-Tag in the .htaccess file of an Apache-based web server.

An Overview Of Robots.Txt File:

If a website doesn’t already have a robots.txt file, it can be created manually. To check if a website already has a robots.txt file, simply enter the website’s URL into the browser’s navigation bar. The primary purpose is to disallow search engine crawlers from accessing certain sections of the website, such as the /wp-admin/ area, to save the crawl budget.

However, it’s also essential to allow access to resources that can assist search engines in understanding how the website crawls and renders, such as the /wp-admin/admin-ajax.php page.

In addition, the robots.txt file typically includes a link to the website’s sitemap, which helps search engines discover the site and builds trust since only the website owner has the authority to edit the robots.txt file.

What are the Exclusion Standards Of Robots.Txt File?

The Robots Exclusion Standard is a method for giving search engine crawlers instructions on which parts of your site to crawl.

Why Is It Necessary?

This standard provides ways to direct crawlers on the areas of your site to crawl and which ones to avoid. These crawlers, known as BadBots, can include:

Spambots
Malware
E-mail Harvesters

The User-Agent specifies a search engine crawler and Disallow instructs the User-Agent not to crawl particular sections of your site. The article also covers non-standard robot exclusion directives, such as Allow, which allows crawlers to access a file within a directory that has a Disallow directive.

Crawl-delay limits the speed of the crawler, and Sitemap includes your XML sitemap in your robots.txt file. Wildcards can be used to group files by file type. You can add or edit the robots.txt file by accessing it through your web hosting files or by using a CMS platform such as WordPress.

Important Points To Consider

When creating a robots.txt file, there are common mistakes that website owners should avoid to ensure that the file works as intended. One common mistake is blocking search engine crawlers from accessing the entire website by adding the following rule:

User-agent: *

Disallow: /

This rule tells all search engine crawlers not to access any page or section of the website. This is a mistake because it prevents search engine crawlers from accessing any page on the website, which can negatively impact its visibility on search engine result pages. Another common mistake is using the robots.txt file to hide sensitive information such as login pages or other confidential information.
