What is Robots.txt and its Purpose in SEO
Robots.txt file allows the search engine bots to crawl the website and tell them about the crawlable area of the website. That’s why the name of the file is robots.txt file because it manages all the search engine bots to crawl the website.
The two main purposes of the Robots.txt file
1. It contains the name of the search engine bots that crawl the website and indexes it on their web search result.
(Note: We should allow all the search engine bots in our robots.txt file. For that, we use an asterisk (*) sign.)
2. It defines which sections of the website are crawlable by the search engine bots and which sections are to be restricted.
( Note: It is very important to prevent some parts of your website to crawl by the search engine bots)
Which Sections should be allowed to index and which should not?
Everything which is important such as pages, landing pages, blog posts, custom post types like portfolio, courses, gallery, work, etc (according to the website) should be allowed to index. Because these pages have all the content or information which you want to reach the public.
All the unimportant things like tags, categories, taxonomies, labels, thank you pages, backend administration pages, etc should not be allowed to index. As these things are to sort the content in your website or blog but it is useless for the end-users. You can also disallow the posts or pages which you want to make online but private and available to only those who have the link for the same.
Syntax and Structure of Robots.txt file
User-agent: * Disallow: /
The asterisk (*) after “user-agent” means that the robots.txt file applies to all search engine bots that visit the site.
All the URLs after “Disallow” tell the bots not to visit those pages or links on the site.
Similarly, all the URLs after the “Allow” tell the bots to visit those pages or links on the site.
(Note: you can also add your website’s sitemap here. your sitemap includes all the important pages and posts)
Nofollow and Noindex Directive for Robots.txt file
Another 2 important aspects of the Robots.txt file are Nofollow and Noindex.
Disallow only prevents the search engine bots to crawl particular web pages. However, it doesn’t actually prevent the pages from being indexed.
Therefore we use noindex directive. It tells the search engine bots not to index specific web pages.
You can also use noindex in the robots.txt file. The format is as follow:
Nofollow works the same as the nofollow link. It tells the search engine bots not to crawl the links on a specific web page.
Nofollow directive of the Robots.txt file implements in the meta tag in the head section of your webpage. The syntax and structure are as follow:
Place this meta tag in between the <head> tags.
