‘The Supermarket effect’, and how to minimise it…
Dan Thornton | November 18, 2008
I’ve coined the term ‘the supermarket effect’ in conversation and in passing, and never really publicly defined it. So for future reference:
The Supermarket Effect: The initial response to a new layout to a website, which echoes your first reaction to a supermarket changing it’s layout; ‘Oh, for crying out loud, where have they put the sodding milk’. Despite the fact that the change may actually be an improvement.

Even after a decade of making, changing, relaunching and tweaking websites, I’m as guilty of letting myself have the same reaction occasionally, before taking a deep breathe and evaluating what the changes actually mean.
And that effect can be devastating when you’re just launched a design you (or your team) worked on for days or weeks, and the first responses from users is to complain about every change. But if you understand that a percentage of shock is inevitable, you can start to seperate the valid and constructive comments from those of surprise – just remember that if they’re regular users of the site, it’s akin to walking into your local pub, or you living room, and finding someone has moved everything.
But there are ways you can minimise ‘the supermarket effect’.
- Warn users that change is coming. Give them time to prepare themselves.
- Explain in detail to key users what the changes will be, why they are being made, and give them an advanced preview. Get them onside, and they will evangelise the changes on a personal level which you wouldn’t reach as quickly.
- Use A/B testing to reveal the changes to a small group and evaluate which changes are making the important differences.
- Consider changing in phases, or offering a choice of old and new. Eventually you’ll have to force the late adopters across but it gives some of your audience a chance to get used to the new layout and help the latecomers.
- Don’t dismiss the responses – even those which are purely critical of any change – politely explain the reasoning behind the changes, and the evaluation of them.
One famous example of reaction to change was Facebook’s unveiling of a new design. It led to vehement opposition, but over time, people do accept the changes, as long as there is value in making them for users. And if not – why are you making the change?
So are there other ways you can make a substantial change to your website, and minimise ‘the supermarket effect’?
