Beyond the hype: big behavioural data

Although almost no one can tell you when data is "big" or not, we all want do “something” with big data.

But collecting terabytes of data doesn’t guarantee we will also use the available data very useful. Three recent trends begin to change the status quo.

Methods for analysing big data have improved, so we are better able to focus on the important data and ultimately make a shift from analytics to actual actions.

Digital seduction: why customers buy your product

Economists at some point decided that consumers make informed product purchases: A good balance between price and quality.

For decades, however, this view is falling apart, as consumers’ decisions are not rational. In my opinion this explains the differences in conversion between online and offline stores.

Three reasons to stop A/B testing

Successful (online) companies are organised to experiment continuously. This is preaching to the choir, something we all agree on.

But what exactly is the best way to experiment as a company? We don’t necessarily agree on the answer to that question.

This article deals with one of the most used types of online experiments, A/B tests.

I would like to explain why you should stop running them.


They changed the rules of online marketing without even notifying us

A colleague of mine, Arjan (@arjanharing), is a great table tennis player. And when I say great, I mean great: I have witnessed a table tennis tournament in our offices during a BBQ with over a 100 people, and nobody – repeat nobody – was able to return his service. 

Now, I must admit that his service is definitely his main strength in the game. I mean, he is a good player, but the exceptional service makes him a player who is hard to compete with even for the well trained and the profs.  

But recently, “they”, the people who run the table tennis rules, decided to change the rules of the game. 

The change might seem minor to you and me (assuming here that you are, like me, not a trained table tennis player): they changed the way in which you are allowed to hold your hand when throwing the ball into the air to serve.

When I heard about it—and tried it—I could not really tell the difference. However, to Arjan, a trained expert, the little change of rules made him loose his extraordinary skills. A drop from exceptional to mediocre, by a little change of the rules. 

Now, why would you care about changes in the rules of table tennis? Well, that’s because the emotions that overwhelmed Arjan when notified of the change share lots of similarities with the emotions that are overwhelming internet marketers all around the world: “They” are changing the rules of the game.
