Why do we need A/B tests?

Long story short - to improve conversions. The main advantage of AB-testing is making the right decisions.

Real world example: you have a two implementations of free trials on your website. In the first case, you require a card number to sign up, and for the second your user can proceed to the platform without the card. What is the best choice in that case?

AB test with two branches can show you the right answer. Your decision will be based on the number of completed sign-ups and the final number of the paid users in these branches.

Our first task with A/B test

Task definition

Our task is testing the most convertible color of form button. For example, your current color of sign up button is blue, but you want to check, what if the green button will be more convertible?

Goal:

to test most convertible color of form button

Branches:

red - 33%, green - 33%, blue - 33%.

Technically:

assign the color of the button: which the user got into.

Creating first A/B test on ABR side

So, there are the step to be done:

Step 1: Sign-up by the link

Step 2: Create your experiment

Pay attention to the Experiment ID. You will use it as the identifier of experiment to run it.

Step 3: Grab the data

After creating the A/B test you can to get the important data to run it.

Experiment id:

Token:

Application side | Start coding

Step 1: Install

Install the library to your codebase on PHP: https://github.com/abrouter/symfony-abtest

This library based on main ABRouter client: https://github.com/abrouter/abrouter-php-client

Install the package:

composer require abrouter/symfony-abtest

// config/bundles.php

return [
// [...]
Abrouter\SymfonyClient\AbrouterClientBundle::class => ['all' => true],

];

Configure the client:

Put your ABRouter token in /config/packages/abrouter_client.yaml

abrouter_client:
  token:                ''
  host:                 'https://abrouter.com'

Step 2: Code

Now we are ready to code. Also, you can check an example of fully completed code on GitHub:

https://github.com/abrouter/symfony-abtest

Step 3: There is our result

Color of the button will be automatically changed on each request for every page reload. Because we have used uniqid(). ABRouter system will memorize the relation between user identifier and branch he got, so if we will repeat the request with the same user identifier we will get the same branch as on previous run.

I have shown you how to implement an A/B test with Symfony framework via ABRouter. Looks like it's quite simple.
Please, remember, that every change that you are making to the app should be through an A/B test. It's a key to build a successful product.
