A rating is a useful starting point, but the distribution and detail behind it matter more than a single average.
Look for repeated patterns
One unusually positive or negative review can reflect an exceptional situation. When several people mention the same strength or problem across different dates, that pattern is much more useful.
Check the business response
A calm, specific response shows how a team handles feedback. Look for acknowledgement, a practical next step and evidence that the business understands the issue.
Match reviews to your needs
The best choice is not always the highest score. A detailed four-star review may reveal that a service is ideal for your priorities even if it was not perfect for someone else.
The reminder to look at patterns instead of one dramatic review is especially useful.
