NAME

CGI::Application::Plugin::AB - A/B Testing for CGI::Application-based applications.

SYNOPSIS

  use CGI::Application::Plugin::AB;


  # Your application
  sub run_mode {
    my ($self) = ( @_);

    my $version = $self->a_or_b();
  }

DESCRIPTION

This module divides all visitors into an "A" group, or a "B" group, and allows you to determine which set they are a member of.

MOTIVATION

To test the effectiveness of marketing text, or similar, it is sometimes useful to display two different versions of a web-page to visitors:

  • One version will show features and a price of $5.00

  • One version will show features and a price of $10.00

To do this you must pick 50% of your visitors at random and show half one template, and the other half the other.

Once the user signs up you can record which version of the page was displayed, allowing you to incrementally improve your signup-rate.

This module helps you achieve this goal by automatically assigning all visitors membership of the A-group, or the B-group.

You're expected to handle the logic of showing different templates and recording the version the user viewed.

METHODS

import

Force the a_or_b method into the caller's namespace.

a_or_b

Return whether the visitor to this site is in the A-group, or the B-group.

No significance is paid to which group the visitors are member of in this module, it is expected you'll handle the logic yourself:

  • Show a different template to members of the different sets.

  • Record the set membership when a user signs up, etc.
