Five stars, would recommend!

Have you ever checked the reviews on a book before buying it?

Or on a restaurant before making a reservation?

Or on an app before subscribing to it?

Or on a movie before watching it?

I’ll bet you have... I know I do!

Why do we do this?

Because we don’t want to waste our time and money.

And reviews are a decent proxy signal for what your experience will be like if you take a chance.

Here’s the thing...

Reviews are a purely subjective measurement.

And yet, people - including your clients - use subjective data to measure important things all the time.

To dismiss “purely subjective” data in a business context would be absurd.

It’s the most important kind of data.

Yours,
