GACE

Google Analytics Content Experiments + Rails = AWESOME

Installation

Add this line to your application's Gemfile:

gem 'gace'

Update your view layout to include the necessary javascript. Make sure to include the javascript at the very top of your head element (per Google Analytics installation instructions).

<<!DOCTYPE html>
<html>
<head>
  <%= gace_javascript_include %>
</head>
<body>
</body>
</html>

Usage

Setup experiment in Google Analytics

Configure each variation with a different gace_var parameter value.

example:

control: http://mysite.com/signup
variation one: http://mysite.com/signup?gace_var=expensive
variation two: http://mysite.com/signup?gace_var=cheap

Make sure to record the newly created experiment ID.

Configure the experiment within Rails

class UsersController < ApplicationController
  def show
    define_experiment :test_pricing, '28391929-0'
  end
end

Create views for experiment variations

Create a directory for the experiment: app/experiments/EXPERIMENT_NAME (ex: app/experiments/test_pricing)
Create a directory for each experiment variation. The directory name must match the gace_var parameter used when setting up the experiment in Google Analytics. (ex: app/experiments/test_pricing/expensive and app/experiments/test_pricing/cheap)
Create any views/partials to be used for that variation. Each directory should mirror structure used by app/views and will override the default views if one exists. (ex: app/experiments/test_pricing/expensive/users/show.html.erb)
