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.

Virtual Robots.txt

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.

PHPEnkoder is a port of the excellent <a href="http://hivelogic.com/enkoder" rel="nofollow ugc">Hivelogic 
Enkoder</a> to PHP and, more specifically, 
to WordPress. It is used to display text in a way that users can see 
and bots can’t.
The encoding system is directly and unabashedly stolen from the 
BSD-licensed source of Hivelogic Enkoder, which works by randomly 
encoding a piece of text and sending to the browser self-evaluating 
Javascript that will generate the original text. This works in two 
ways: first, a bot must first have a fairly complete Javascript 
implementation (in particular, it must have <code>eval</code>); second, the 
decoding process can be made arbitrarily computationally 
intensive. This is similar to the idea of charging computational 
payments to send e-mail, only this is actually implemented.
By default, PHPEnkoder scrambles e-mails in plaintext and in <code>mailto:</code> 
links. It additionally provides a shortcode for manual scrambling, 
used like so: <code>[enkode text="shown to non-JS browsers"]this will be 
scrambled[/enkode]</code>.

PHPEnkoder

Encodes mailto: links and e-mail addresses with JavaScript to stifle webcrawlers.  Automatically turns plaintext e-mails into (enkoded) links.
