You’re wrong more often than you’re right – an article for Marketer+

You’re wrong more often than you’re right.

(when it comes to website optimization)

I know, hard to swallow. But I have data for it:

➡️ Only around 10% of the changes tested on Airbnb, Booking and Netflix produce a statistically significant improvement in the metric they were meant to improve.

➡️ On average, only around 20% of ideas meant to raise a website’s business results deliver the expected outcome.

Which naturally raises the question – since we’re wrong so often, how do you make sure what you change on your site actually works?

I talk about that in the latest issue of Marketer+.

In my piece you’ll learn:
🟢 how to make better decisions about changes on a website,
🟢 how to cut down on shipping weak ideas,
🟢 what affects conversion rate,
🟢 whether correlation always means causation.

Link to the latest issue of Marketer+ HERE.

You’ll also find it at Empik stores.
