Noindex provides a simple way for Ruby on Rails applications to tell search engines what to index on your site and what to not. It inserts <meta name="robots" content="noindex"> at necessary pages.

Add this line to your application's Gemfile:

gem 'noindex'

And then execute:

$ bundle

Or install it yourself as:

$ gem install noindex

Add noindex_meta_tag helper to the head element of your layout. HAML example:

html
  head
    = noindex_meta_tag

It will generate following meta_tag element (for new and edit actions by default):

<meta content="noindex" name="robots" />

Noindex simply adds a method noindex to controllers. This method is just a before_filter so it receives same options as a Rails before_filter method.

By default Noindex filters new and edit actions. You can customise this by calling noindex in any controller. For example to hide only index and edit actions in UsersController from search engines your can do:

class UsersController < InheritedResources::Base
  noindex only: [ :index, :edit ]
  ...
end

If you want some actions to be searchable you can call skip_noindex method (that is just a skip_before_filter alias).

class UsersController < InheritedResources::Base
  skip_noindex only: [ :new ]
  ...
end
