what is robots.txt?

[Xtremeux]

1. The robots.txt is a simple text file in your web site that inform search engine bots how to crawl and index website or web pages. By default search engine bots crawl everything possible unless they are forbidden from doing so.

2. They always scan the robots.txt file before crawling the web site. Declaring a robots.txt means that visitors (bots) are not allowed to index sensitive data but it doesn’t mean that they can’t.

3. The legal/good bots follow what is instructed to them but the Malware robots don’t care about it, so don’t try to use it as a security for your web site.

Robots.txt is a text (not html) file you put on your site to tell search robots which pages you would like them not to visit. Robots.txt is by no means mandatory for search engines but generally search engines obey what they are asked not to do. It is important to clarify that robots.txt is not a way from preventing search engines from crawling your site.
