Description

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.
