A HitchHackers guide through WordPress

If a blog is marked as not being public then the noindex meta tag will be output to tell web robots not to index the page content. Add this to the wp_head action. Typical usage is as a wp_head callback. add_action( ‘wp_head’, ‘noindex’ );

function noindex() {

	// If the blog is not public, tell robots to go away.

	if ( '0' == get_option('blog_public') )

		wp_no_robots();

}
