Out of the box, MVT experiments with GWO will serve up all possible permutations for an experiment.
Sometimes you want to create sections that are related to each other. For example – a header and footer section that need to be coordinated with each other. The red header needs to be displayed with the red footer and the blue header needs to be displayed with the blue footer.
There is a very simple solution to this.
Just create the experiment as usual and right after you launch the experiment use GWO’s pruning function to remove the combinations you don’t want to serve up (i.e. the red header with the blue footer and the blue header with the red footer).
