FAQs About How Pay-Per-Result A/B Testing Optimisation Works

ab_testing_2You have probably thought many times about how you could improve your site sales and conversion rate. Here are the most commonly asked questions to get you started.


How does Pay-Per-Result A/B testing work?

Normally, other agencies charge clients for each test regardless of the test result. With the Pay-Per-Result A/B Testing, you pay only once the test delivered a statistically valid result. A test is only valid when 95% confidence level has been reach. Then you pay only for each percentage improvement gained (see table below). With this approach, no win no fee applies.

The improvement gained is calculated from the testing tool, which also calculates statistical validity of the test, conversion reached and number of visitors who viewed the test.


When do I pay the fee?

The fee is payable once a test has finished successfully at 95% confidence level. Then you will receive your invoice along with the final test result.


What does that mean 95% confidence level?

It means that we are 95% confident, that the test result is solid and that there is only 5% chance for this not to be true. 95% confidence level is used by all leading testing agencies, major online retailers, including me, to determine a winning variation.

I have 9 Years of Tremendous Experience as web analyst and Senior Conversion Specialist. I have worked on optimisation project for the second-largest store retailer in the USA (the company is also a component of the S&P 500 Index), as well as for a well-known USA fashion retailer with over 380 stores nationwide. Over the course of my career I have achieved many INSANE improvements on our client’s websites, sometimes by applying best practices, another time from findings I made during conversion audits and sometimes thinking out of the box. For one of them I have even received an award in 2012 from WhichTestOne, where after testing different emails and parts of email message we increased revenue by 303.08%. What might also interest you is the fact that my average conversion improvement is 19% and my success rate is 70%. Basically, I’m VERY GOOD at what I do thanks to my Can Do Attitude to find solutions to given problems & Experience in this field.
