Why reviews matter

Reviews are the closest thing to a conversation with someone who went before you. Left well, they save the next person a great deal of guesswork.
What makes a review useful
The least useful reviews are the ones with no detail in either direction. Brilliant, thanks and Awful, avoid tell the next reader nothing they can act on.
- Say what you expected and whether that is what happened.
- Mention specifics — timing, communication, condition, anything concrete.
- Note what you would do differently if you were doing it again.
- Keep it proportionate. One bad moment in an otherwise good experience is worth saying, but worth framing.
If you are on the receiving end
A critical review is not an emergency. How you respond is read far more carefully than the review itself, often by people who have not yet decided about you.
- Wait until you are not annoyed.
- Answer the specific point, not the tone.
- Say what you have changed, if anything.
- Leave it there. Long arguments help nobody.
A thoughtful reply to a critical review persuades more people than a page of five-star ratings with nothing written underneath them.
On honesty
It is worth saying plainly: reviews are only worth anything if they are real. Feedback that has been bought, traded or written by the person being reviewed damages the one thing that makes any of this useful. It is also, in our experience, obvious to readers far more often than the people doing it expect.
A reasonable habit
Leave a review while it is fresh, within a day or two. Say what happened. Be as fair as you would want someone to be about you. That is genuinely the whole of it.
