This simple and lightweight plugin adds a «Hide from search engines» checkbox above the publish box to pages. By
ticking this box, a meta tag will be placed into the <head> section of your page specifying that robots should
not index the page.
By default this only applies to pages. You may extend this functionality to posts or other custom post types with a small bit of code. See the FAQ’s tab for further instructions.
