Inside Issue #16 Customer Reviews In A Sea Of Noise
Learn how we increased Purchases by +7.8% with 4 variations and a feint signal.
Can customer reviews lead to more purchases? Common sense would suggest that they carry a strong element of social proof and therefore should be effective. To answer this question, four interesting variations were created. As the testing days rolled on, high traffic on our side, it became clear that the effect would be rather small and our struggles began. Here is how we navigated through a sea of noise to arrive at a recommendation.

Discover Testing Strategies As We Show Process
Use Datastories To Learn About How We Constantly Improve Our A/B Testing Strategies
A good testing strategy is quite simple on paper. The best tests, we believe, are characteristic of: lowest effort, highest effect, highest certainty, and lowest duration. We are constantly learning and driven to be the most efficient in our testing with the above criteria in mind. As we share our complete testing process from real consulting projects with real clients, you will learn along with us.


Not Everyone Has The Time Or Traffic To Run A Test
Use Datastories To Inspire Your Design Teams
Surely, one of the best ways to optimize your online business is to experiment with A/B tests. After all, you can only improve what you can measure. However, tests may take weeks or months of waiting and thousands of unique visitors to get good data. Some businesses will cut corners and act on misleading or insignificant results which can actually backfire and hurt your numbers. Instead, Datastories come with proper sample sizes, and tests with multiple variations worth precious weeks in design, implementation and analysis efforts alone. Know that the high quality results we share with you are repeatable and can be relied on to guide your business. The GoodUI ideas that we test can be used for inspiration as we see if they work in isolation and in various combinations.


Understand The Strength Of Losing & Winning Tests
Use Datastories To Learn About Both What Works & What Doesn't
We don't shy away from being honest in our reporting of test results. Always striving for high reusability, we start off by communicating clearly the primary and secondary goals of each test, including the exact way those are measured. On each experiment we also always share sample sizes, absolute conversion data and ranges for each variation so that you can assess how valid the effect really is. Finally, in our elaborate data tables we also do calculate and color code significance levels with p-values for you. Sample Data

Some Of Our 470+ Happy Members That Use Datastories For Inspiration
I was very curious how GoodUI Datastories would be. After receiving the first issue I can say that it’s a great piece of professional work. I was feeling like sitting right next to Jakub and Vlad while they prepared and ran the tests. It’s a great thing to have everything provided in such detail. Imagine as if you actually ran these tests but it took you just a reading moment and not 3 months. Great isn’t it? ” - Robert Rafiński, Project Manager, Oponeo.pl
I really appreciate your guys' work and attention to detail. Not just on the account, but the Datastories. Really great work; it saves me a ton of time in making decisions for my SEMs on split testing. We're in a high growth mode at the moment, so Datastories is just what I needed to save me time in directing my team. ” - Thom Hutter, Director, Insight Marketing Solutions
So far to be honest, I was expecting more than 1 lesson per data story. However I know how much effort and time probably goes into making it great. It was nice to receive the next one right away though. Overall they are great quality and I'm learning. ” - Kris Kayyal, Marketer, MaxCDN.com
