Time Limited Offer Test – Revenue Increased by 24.5% and Orders by 18.5%

Almost on every website nowadays you will find offers like save 20% etc. The question is how to make them work just beautifully? My answer: limit your offer with an end time, i.e. offer an expiry day, thus create a scarcity. By doing so, on a website which was selling annual plans for their membership and was already offering 40% off the second year I have increased revenue by 24.5% and orders by 18.5% just by making a very little change on their website. That change took 1-2 hours of developer resources to implement. Below are the changes I have tested. Yes, all what we have done was adding a line of text ‘Offer expires 31st March’ into two strategic places on this pricing page. One below the site main headline and another right in the pricing plans table, just above the main join CTA.     Orders screenshot We […]

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

You 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 […]

Consequences of Ending Your Test Too Soon

In this post we will talk about the consequences of ending your A/B test too soon. The idea came to me when I saw some A/B and MTV tests case studies, which after running only a few days were declared as winning by the testing tools. Then I got ‘lucky’ and came across this very good example, as one of our tests we were running turned out to be a winning one on the following day. Mind you, this was a site with a high volume of traffic. Let’s have a look at this actual example below. The following day after we launched the test, our testing tool declared a winner. According to our testing tool, we improved our conversion by a respectable 87.25% with 100% confidence level. Great! Well, not really. What’s the issue? Technically, if you input the data (conversions & visits) into any statistical tool, it would […]
