Segmenting your audience to show different content can be hugely valuable, and is a great stepping stone to personalisation

Personalisation is hugely powerful, but if you don’t spend time optimising the wider user experience through split testing, conversions will suffer

• When it gets creepy

• When a brand loses it’s identity

• When resources are a limiting factor

3 Key Takeaways1.) Split testing will optimise for the “average” user, but without segmentation and personalisation you’re missing out on revenue
