Setup your first A/B test
*************************


Overview
===============

What is A/B testing?
---------------------
Testing is a way of showing users different variations of your app, and then measuring how each variation affects your goals.  For example, if you're interested in having your users make more in-app purchases, you might test the phrase "buy more coins now!" versus "save time by buying coins".  Arise's A/B testing tools can tell you which one will make you more money. You can also use Arise to test new in app-features, evaluate performance and roll out changes without resubmitting your app.

What is a conversion?
----------------------
Tests are only good when they can measure some metric and show you which path is performing better.  To help out our system, that metric should be a "conversion". Good examples of goals are things like an in-app purchase, a new account created, or even a tap on an advertisement. We can then calculate the `conversion rate`_ (Number of conversion/ Number of views).

.. _`conversion rate`: http://en.wikipedia.org/wiki/Conversion_rate


Getting Started
===============

1. Create an account
--------------------

If you do not have an account yet, register on the dashboard_. The dashboard is your tool to configure your experiment variation.

2. Configure your variation
---------------------------

The current system supports only one experiment and two variations.

Variation values
+++++++++++++++++

Variation values will be transmitted to your app. You can experiment:

* call to actions
* headline, product descriptions (words, style, number of words)
* in-app purchases (prices, multiple contents)
* forms (types of fields, length, layout, error handling)
* layout and design (position and grouping of content)
* images

You need to set different values for each variation. We will consider the variation A as the default variation (control).

Distribution
++++++++++++

You can set the distribution of your variations. The total of all the variations must always be 100%. You can for example set 70% on the variation A (control) and 30% on the variation B (test). Once your app is deployed, you will be able to view the conversion rate for each variation.


3. Install the Arise SDK in your app
-------------------------------------

We currently support iOS and Android. Please read the following documentation to install the Arise SDK in your app:

* :doc:`ios`
