Why robots file is needed?

[mvminfotechseo]

In a nutshell. Web site owners use the /robots.txt file to give instructions about their site to web robots; this is called The Robots Exclusion Protocol. The "User-agent: *" means this section applies to all robots. The "Disallow: /" tells the robot that it should not visit any pages on the site

You might be surprised to hear that one small text file, known as robots.txt, could be the downfall of your website. If you get the file wrong you could end up telling search engine robots not to crawl your site, meaning your web pages won’t appear in the search results. Therefore, it’s important that you understand the purpose of a robots.txt file in SEO and learn how to check you’re using it correctly.

A robots.txt file gives instructions to web robots about the pages the website owner doesn’t wish to be ‘crawled’. For instance, if you didn’t want your images to be listed by Google and other search engines, you’d block them using your robots.txt file.

In SEO, robots.txt is essential because it is important to submit it if the website is newly built and all the webpages are not ready. It is a file that contains the commands through which we instruct web crawler to not crawl and index it.

Some common use of Robots.txt are

Preventing duplicate content from appearing in SERPs (note that meta robots is often a better choice for this)
Keeping entire sections of a website private (for instance, your engineering team’s staging site)
Keeping internal search results pages from showing up on a public SERP
Specifying the location of sitemap(s)
Preventing search engines from indexing certain files on your website (images, PDFs, etc.)
Specifying a crawl delay in order to prevent your servers from being overloaded when crawlers load multiple pieces of content at once

Robot.txt is used to crawl the pages website. It tells that which part of the area should not be accessed. We can define the pages which should not be accessed by putting the disallow tag in robot.txt. Those disallow pages are restricted to visit. It also help to index the web content.

You can ask your web hosting provider to upload it under your control panel (root directory of the website) and webmaster will pick it automatically.

If you have access then you can upload it from your end.

The robots.txt file contains information that tells the search engine that the site may or may not be indexed. You can allow the search engine to index or not index any page in your website by changing the command in the robot.txt file.
