Hello Friends,

Robot.txt files tell your instructions to a search engine robot. It depends on what you what it to do. If you don't have the robot.txt file then when a robot visits your site and if it doesnt find the file, it will start to visit all the pages and contents of your site. These files are like walls which helps in preventing some files like java scripts, some images or any other files from indexing. It is also important to make a note that it is not a method that prevents search engines from crawling your site. So it is important to create a robot.txt file

There are many search engine are available on the web. When a search engine crawler comes to the site, it will look for a special file on your site. That file is called robots.txt and it tells the search engine spider, which Web pages of your site should be indexed and which Web pages should be ignored.

It is important to clarify that robots.txt is not a way from preventing search engines from crawling your site (i.e. it is not a firewall, or a kind of password protection) and the fact that you put a robots.txt file is something like putting a note “Please, do not enter” on an unlocked door – e.g. you cannot prevent thieves from coming in but the good guys will not open to door and enter. That is why we say that if you have really sensitive data, it is too naive to rely on robots.txt to protect it from being indexed and displayed in search results.

As per my info; Robot.txt is extremely helpful to stop the google crawlers where you do not need them to cache your WebPages or admin pages.

Hello,

Thank you very much.Tips are really helpful.Thank you very for sharing your views with us.

Robots.txt files inform search engine spiders how to interact with indexing your content. By default search engines are greedy.They want to index as much high quality information as they can & will assume they can crawl everything unless you tell them otherwise. Robots.txt is often found in your site’s root directory and exists to regulate the bots that crawl your site. This is where you can grant or deny permission to all or some specific search engine robots to access certain pages or your site as a whole.This file is used to communicate with search engine spiders telling them what they cannot have access to.

I was wondering what that was. Thanks guys.

Robot.txt is great when search engines frequently visit your site and index your content.

The main importance of Robots.txt files is that it tells the search engines which pages to access and index on your website on which pages not to. For example, if you specify in your Robots.txt file that you don’t want the search engines to be able to access your thank you page, that page won’t be able to show up in the search results and web users won’t be able to find it. Keeping the search engines from accessing certain pages on your site is essential for both the privacy of your site and for your SEO.

Robots.txt is a simple text (not html) file you put on your website root directory to tell search robots which pages you would like them not to visit. By defining a few rules in this text file, you can instruct robots to not crawl certain files, directories within your site, or at all.

thnx to all
