“We always test to see what visitors like”
Of course, there may be other tactical ways to come up with compelling lead generation strategies, but most of the digital marketers rely on AB testing and they have actually developed a “we should test this and test that” mentality.

Multiple Testing/Comparisons Problem: How Adding More Variations To Your AB Test Will Impact Your Results?
I will take you back to 2007 to one of the very first CRO projects we conducted for a large online retailer. The website received a massive amount of traffic (100k per day). Since it was one of our first projects, and the team was a bit trigger happy with AB testing, our first test included 30 different designs to run against the control. The headache of implementing all of these designs was overwhelming. None the less, we launched the test after about six weeks of implementation.
Seven of our challengers beat the original design within five days. The team …Read More

I have meant to write this post for a long time. There has been a lot written about one-tailed vs. two-tailed tests.

If you are not interested in these, you can skip them! Special thanks to our data sciences team that checked and …Read More
There are hundreds of case studies and examples on AB testing, explaining what makes it highly useful for conversion optimization. While AB testing is important, it is a mere component of the overall CRO process. What’s critical to keep in mind is not dive into AB testing right away until you know everything about interpreting, analyzing, and understanding test results.
AB testing isn’t foolproof and like anything in statistics, results can simply be wrong. But the more you know about what makes a test valid, and basic statistical concepts, the more likely it is that you will not face …Read More

Wild guesses and opinions often only result in delusional outcomes. Though opinions are by far the most widely accepted truth, they rarely are factual. It is a better practice to lean on deductive reasoning and logic instead of guesswork. But how do you arrive at what is labeled as a fact or a valid statement? Experimentation is the key.
