What is robot.txt file? A SEO Guide for robots.txt

What is robots.txt?

Robots.txt is a file that tells search engine crawlers or spiders which URLs they can access on websites. It limits access to the functions of web crawlers. With the help of this file, engine spiders know what certain pages are needed not to crawl. You can use the robots.txt file, especially for three reasons: blocking non-public pages, optimization of crawl budget, and preventing indexing of resources. Most search engines like Yahoo and Google recognize this file and honor it. 

The location of your robots.txt is the root of your site. 

Why is the robots.txt file important?

Most websites don’t need this file because Google can index all required pages and automatically doesn’t index pages that are not wanted. Having said that, there are three major reasons why to use the robots.txt file as a part of your routine SEO Audits

1). You can block non-public pages. Usually, you don’t want some of your pages indexed. You want them to exist but don’t want people to land on them. So, in this case, you can use robots.txt to block some pages from search engine spiders and crawlers.

2). You can prevent the indexing of your resources. You can use meta directives to block some pages from indexing. But they don’t work well when it comes to multimedia resources such as images and PDFs. 

3). You can maximize your crawl budget. If all of your pages are indexed, you can have a budget problem. If you block some pages from indexing, Googlebot can spend your budget on the pages that matter.
