A robots.txt file is responsible for providing instructions to search engines on how they can crawl a website. The file can be found in the root directory of the website. The website is example.com/robots.txt. Keep reading about what is robots.txt file is in seo.
The file consists of a set of Allow and Disallow directives that tell search engines which sections of the website they can crawl and which ones they cannot. It is possible to give general instructions to all bots or to target a particular one using a user-agent directive, which can prevent a particular bot from accessing a section of the website.
Finally, it is possible (and recommended) to add a sitemap declaration to the end of robots.txt, telling search engines the URL where they can find the XML sitemap. Understand first what robots.txt is.
User Agents
User agents show how search engine bots identify themselves when accessing the website and what can or cannot be accessed. For example, you could block Google from accessing a section of your website using the Google-bot user-agent.
It is essential to note that when you define multiple user agents in the robots.txt file, each one will ignore the directive meant for others and will follow only the instructions specifically assigned to it. Therefore, it’s significant to understand how to review or check robots.txt files.
Allow and Disallow
The way you have to indicate to robots whether or not they can access a section of the web is through allow and disallow directives, the latter being the most common.
The disallow directive serves to inform search engines that they are prohibited from accessing that part of the website. Thus, once a disallow is placed in the file, the assigned user agents will stop crawling that part of the web page.
By blocking search engines from accessing certain parts of the website, you can prevent them from wasting time and resources crawling sections that have no value to us, such as shopping carts, login or user account pages, or private sections.
XML Sitemap Declaration
All robots begin their crawl by accessing the robots.txt file to find out which pages on the website they are allowed to access. Therefore, it is advisable to include an XML sitemap declaration at the end of the file to tell the robots where your sitemap is located.
If your website has more than one sitemap, it is possible to indicate where each one is located. However, it is more advisable to add the URL to the sitemap index if you have one. In any case, declaring the sitemap is not mandatory.
Crawl-Delay
The Crawl-delay directive is used to tell the different robots how much time should pass between each crawling action they perform.
This directive is no longer used by Google, since it does not adapt to each website so as not to make a high number of requests that could saturate the server on which it is hosted. However, other search engines, such as Bing or Yandex, continue to use this directive.
Why is Robots.txt Important?
Robots.txt allows you to have greater control over the way search engines crawl your website, telling them which sections they can and cannot access.
Every website is completely different, so there is no one robots.txt file that fits every website.
A few sections you might wish to block include:
- Faceted e-commerce navigation
- Testing sections
- Internal search results pages
- Login pages and user profiles
Shopping Carts
Restricting access to unimportant pages or those with duplicate or minimal content, like faceted navigation in e-commerce, prevents the Google bot from wasting crawl budget and allows it to concentrate on the pages we value
It should be noted that the robots.txt file only prevents the URL from being crawled. This doesn’t mean that search engines cannot guide it. If the URL has links, internal or external, pointing to it, it could be indexed. Also, placing a no-index tag in the header would not prevent indexing, since the robot will never access the URL and will not read this directive.

Once the revised robots.txt file is uploaded, you can now utilize Google’s robots.txt tester to see which directives are preventing Googlebot from accessing your website’s content. Alternatively, tools like Screaming Frog enable you to utilize a personalized robots.txt for crawling, allowing you to verify the proper implementation of the directives before deploying it to production
