Hi charliemwallace,

It is possible to split test with custom order form skins. In fact, we highly recommend clients split test their entire funnel, including the order form, to optimize revenue. Before I give you some pointers on how to conduct split testing, first you should check out a few blog posts we've made in the past about our own approach towards executing and measuring split tests. They may give you some ideas on how to approach this.

When we run a split test on the order form, we plan exactly which variables we will test and which are under a control, the size of the sample set, and the source of the traffic. For example, if we wish to determine how different EU trust logos will perform, we will not include US traffic in that test, only European consumers. It is also critical to understand what sample size you should use and what constitutes a statistically significant result. To put it in perspective, if you flipped a coin one time and it came up heads, you would be mistaken to declare that in all cases, every time you flip a coin in the future, it will always result in heads. Likewise, when you are testing your optimization, you must be in a position to definitively state that the variables you are testing resulted in an increase or decrease in conversion rate. There are tools referenced in the articles I'm linking that will help you determine this without needing to crunch the numbers manually. The important point is to understand the concepts because ultimately, your revenue is at stake.

We have also built a 2 part blog series on how you can improve conversion rate from your Pitch Page. These give you some tips on areas of improvement you should examine as well. We do recommend that you only test one or two variables at most, at a time. Otherwise, you won't know if the change you made on the pitch page or the order form resulted in your new conversion rate, and thus, how to continue optimizing.

Ok, with that preamble out of the way, here are some specific methods you can use to execute a split test with custom order form skins. First, you need to have a few variations of the order form built and available within your account. You will gain maximum control over the consumer's experience if you use the new advanced custom order form. This technology allows you to adjust much of the order form, only using changes with CSS and through custom images that you load into your account. More details on our advanced custom order form feature are here: ClickBank Support: Advanced Custom Order Form Please take time to read the .PDF file included with the .ZIP attachment on that linked page; it will explain some important features and limitations on the CSS modifications you can make, along with some additional guidance on how to split test your CSS files.

Once you have the desired order forms available in your account, you will want to decide a tracking ID that corresponds to each order form. For example, let's say you name order form variant 1 as "Blue Theme" and the second as "Pink Theme". You could then use two tracking IDs called "Blue" and "Pink". Tracking IDs will be tacked onto the pay link as a parameter along with your ClickBank order form skin ID; you will find that ID labeled "cbskin=..." under your account settings -> My Order Form. More details on how to use the skin ID here: ClickBank Support: Custom Order Forms and on tracking IDs with pay links here: ClickBank Support: Creating A Payment Link. Keep in mind that if you use Pitch Plus, you will need to pass the skin ID parameter, before the Pitch Plus Flow ID.

Once you have your payment links created and your tracking IDs determined, you need to construct a split test on your Pitch Page where your payment links will be swapped out as traffic arrives. There are probably some cheap/free tools available to help build dynamic links for the technology platform you happen to use, such as Wordpress. You'll need to consult their guidance for how to present one link to half your traffic and another link to the other half.

When you have your sample size determined and your site constructed, use ClickBank Analytics available from Reporting -> Analytics within your accounts, and change your data to show as Vendor (see radio button on the top left), then choose Order Form Impressions by Tracking ID. Make sure the date range shows the period of time that you are executing for your split test and then look at the results in the data grid below the graph. Each tracking ID will be shown along with order form impressions and conversions. Once you've reached the maximum sample size, use a statistical significance calculator (available online) to evaluate your results and see if you have a conclusive improvement or decrease.

At this point, it becomes a cyclical model where you constantly improve your conversion rate through continued testing. This is how we approach the exact same problem with our tens of thousands of daily transactions.

I hope this is helpful.
Thanks,

Couldn't have asked for a better answer!! Thanks heaps!
