Each project is assigned a unique Convertize Pixel. This is a small line of code that you add to the header of your website. It usually looks something like this:
Adding the Pixel to your website’s source code is in fact the installation of Convertize on your website. It is what allows us to apply the changes your make in your experiment to your live site. It is also responsible for obtaining the data for the results of your experiment.
Without the Pixel installed, you can still play around with the app. None of the changes you make will go live and you will not get any results.
If you have multiple sites, we would always recommend using multiple Projects. One for each site. Remember, each Pixel is unique to each Project, so be sure to install the correct Pixel.
Say you have one site with multiple domains, for example, a French site and an English one. They look and function otherwise the same. In this case you would include these in the same project.
It is important that you carefully use URL targeting to make sure the right changes are made to the right domain. To make sure your scenario for the English site does not affect the pages in French, you must explicitly put down which domain you want to be part of the experiment.
For example, if you wish to change the catalog page on your English domain, make sure to target the URL ‘www.example.com/catalog’ or for the French domain: ‘www.anotherexample.fr/catalog’.
Simply targeting all URL’s that contain ‘/catalog’ would lead to your experiment running on both domains, provided the same pixel is included on both domains.
