This is a very simple plugin that adds a “robots” meta tag to the head of your site with “noindex” in it.
The effect of the noindex robots meta tag is that search engines will not index your pages and posts at all. 
This is a better solution then the wordpress default settings option, which tells search engines to not crawl the URLs in the robots.txt. Because Google (and other search engines) sometimes still index URLs they haven’t crawled, for which they determine relevancy based on anchor text of links which lead to the specific URL.

Virtual Robots.txt is an easy (i.e. automated) solution to creating and managing a robots.txt file for your site. Instead of mucking about with FTP, files, permissions ..etc, just upload and activate the plugin and you’re done.
By default, the Virtual Robots.txt plugin allows access to the parts of WordPress that good bots like Google need to access. Other parts are blocked.
If the plugin detects an existing XML sitemap file, a reference to it will be automatically added to your robots.txt file.

Awesome, a simple solution to a common issue (site content managers who want to hide certain pages from Google search results).

Just a little note: in my case, the existing Sitemap created by the plugin "Google (XML) Sitemaps Generator" by Arne Brachhold wasn't detected.

Efficient and unobstrusive

I like the fact that it's so clean. Thanks for building it!

Does the Job

Virtual Robots.txt automatically creates a robots.txt file for your site. Your robots.txt file can be easily edited from the plugin settings page.
