Introduction to Personalisation
Let us start with some definitions…
✓ Personalisation is “a means of meeting the customer's needs more effectively and efficiently, making interactions faster and easier and, consequently, increasing customer satisfaction and the likelihood of repeat visits. It’s achieved when a system tailors an experience based on a consumer’s previous behaviours. For example, Amazon personalises its home page for each user based on that user’s previous searches, views and purchases.
✓ Customisation, according to Merriam-Webster, is a method of “changing something in order to fit the needs or requirements of a person, business, etc.”
So, What’s the difference exactly?

Can we just ask people?
2. People make bad decisions.90% of product decisions have an inconclusive or negative effect on a product’s primary metric

Short answer – No !
1. Intent vs. Behaviour.
Consumers don't really know what they want or need until they are faced with the product
Hypothesis Testing.
90%
1. <IDEA> How a user is able to perform another search from the Search Results page isn’t immediately clear due to the collapsed Search Box.
2. <METRICS> Shallow: SearchesDeep: Conversion
3. <MAKE IT>

Which one performed better?

● All of us are wrong most of the time
● We want what we do to be profitable
● We want customer sentiment to drive product development
● We want decisions to be based on fact
Why should you do A/B Testing?
Why shouldn’t you be testing?
● You don’t have enough traffic
● You don’t know what success looks like (no success metrics)
● You like being ‘the expert’
Key Takeaways.
● Less is more ● Product Data● Address personalisation● Test everything● Retest everything● Question everything ● Data is power. But with power comes a lot of responsibility.
