The feedback ratings on PPH are an important indicator of the reliability of a user based on their track record on PPH. On a user's profile page you can see the feedback scores they have received on jobs as a freelancer ("My Freelancer Activity") and as a Buyer ("My Buyer Activity"). You will also see their overall feedback rating which is the % of positive (4 and 5 stars) reviews that they have received over the total number of reviews received.
Feedback reviews are given in two ways:
When a freelancer completes a project and the Buyer pays their invoice; both parties are asked to leave feedback for each other.
When a project is canceled and the Buyer receives a refund. If the cancellation was caused by the freelancer (for example due to a problem with delivering the work on time) then the freelancer will automatically receive a 1-star feedback review. If the cancellation was caused by the Buyer then the Buyer will automatically receive a 1-star feedback review.
