How well do you know A/B testing? Admittedly, as an Optimizer or Digital Marketer, you are probably best friends or you know a lot. But one of the things I like about split testing is that even though you think you know it best, it always surprises you. 

Each A/B testing case study comes with its own set of differences and lessons.   

Having questions to ask about A/B testing isn’t just a great way to learn more about split testing, but it’s a great way to avoid making futile mistakes. To do that, though, you need to know all the …

“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.  

In times like these, your site has to remain relevant and keep on generating leads. So, if you need some AB test ideas, this article could be just what you needed. 

One of the questions you should deal with in CRO is the impact a particular page (the homepage for example) or class of pages (product or category pages) on the overall website conversion rate. The answer to that question determines the impact of optimizing that page on your bottom line.

Any experiment that involves later statistical inference requires a sample size calculation done BEFORE such an experiment starts. A/B testing is no exception. Calculating the minimum number of visitors required for an AB test prior to starting prevents us from running the test for a smaller sample size, thus having an “underpowered” test.

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. …

Both user testing and a/b testing are important techniques used during conversion optimization. They aren’t poles apart as far as their purpose is concerned. You can say that they are indeed two sides of the same coin.

The ultimate purpose of user testing and a/b testing is to improve the overall on-site experience for users and to improve the conversion rates of websites. However, one must understand the 8 differences between the two and decide when to pick the right test based on its objective. So, let’s find out what is the purpose of each of these tests.

I have meant to write this post for a long time. There has been a lot written about one-tailed vs. two-tailed tests. However, most of the articles approach the topic from a purely statistical perspective providing many formulas but do not show how to do the calculations. Others articles approach the issue from a high-level business perspective. So, here is my attempt to delve deep into the topic. Some sections in this article are heavy on stats and formulas. If you are not interested in these, you can skip them! Special thanks to our data …

Conversion optimization, much like most SEM activities, touches all verticals and various channels. Each company has its own unique experience, and we always emphasize, no two projects are ever the same. It’s that uniqueness which ensures CRO will succeed for that organization. Nonetheless, projects are brought together with a common thread: the documentation and deliverables that are produced as a result of the research and effort are pretty standard.

Much to my own chagrin, most of our potential clients say that what most CRO agencies say they offer sounds pretty much the same. Obviously, as an agency …
