Why & How to write Robots.txt file for website, blog
Robots.txt file is a great way to tell search engine’s about your site and manage crawler’s to index your site as per your preference. I think most of the newbie bloggers are not familiar with this file, most of them are in a bit fear of Robot.txt file as they think it is hard to edit Robots.txt file and any single mistake can harm their site.
This is same case with me when I started blogging 2 years back but now all of my blogs have Robots.TXT file installed on servers. It will be great if search engine boat crawl and index your website or blog frequently but wait!! But not when they index something which you really don’t thought off. These bots will index everything unless you guide them what to index and what not.

What is Robot.TXT file?
So, I think most of you guys have got the idea of this file but more reference here is detailed definition: Robots.txt is a txt file on your server which tells Search engine bots what to not index….this file also knows as Standards for Robot Exclusion. This is works as a protocol between search engines and websites to crawl and index website/blog content. When Google bot, Bing bot comes to your site for indexing they first need to crawl Robots.txt file and from here they got to know what to exclude while indexing the site. You can easily view this file by just typing http://www.domain_name.com/robots.txt and can see what restrictions you have placed for search engine bots till now.

Better resource management and improved load time
You have often seen many site with having some forms, search bars and many other scripts running when you open their website’s but still they will not take much time. The main reason behind this is Robot.txt file. Actually they have excluded these unusable scripts from crawl bots because these small scripts are made for users not for search engines. No one is going to search for these things on search engine. So, this can improve your site’s load time significantly.
Disallowing Search Robot from indexing your pages or content
Sometimes you don’t need to get index some of your pages or categories or tags. Then at that time Robot.txt is the only way to do it.

This command means any web spider or bots are not permitted to access cgi-bin folder or your site. Like if your cgi-bin/abc.html/ then it will not be indexed.
Hi, as you can see in this command we have Googlebot-Image instead of *. So, here we have specified the Bot name while in above sections * is used for all robots.
This command means Googlebot-Image will not be able to access any file your website. You can also specify your image forlder to robot as well.
Eg. User-agent: Googlebot-Image
This command will tell Googlebot-Image that you should not index any file from images folder.
Similarly you can also use some other parameters in your Robot.txt file to exclude search engine bots from indexing your pages, post, images etc.
