To grow the online business Google Adwords is a major performance marketing channel for Increasing competition of the last months raised prices for keywords and
as a result customer acquisition costs per order.

In addition limitations in the
creation of individual Landingpages for each Ad campaign prevented from improving their Ad conversion rate by adapting the content to the audience.

convertizer was asked to help to increase the efficiency by reducing the customer acquisition costs of the Google Adwords campaigns.


The conversion experts of convertizer created a conversion focused and automated Landingpage in the look-and-feel of the online shop. Product relations for adjustable articles have been
implemented in order to allow presentation of the full assortment for an optimal customer usability.

The implementation of convertizer was done with a convertizer Magento Module which provided the
necessary add-to-basket logic and the tracking code implementation with only a few clicks.
This helped the client to avoid additional IT resources to get convertizer running.
