This and only this should be rating. (Quality of Delivery)
We can't control Fiverr fees, therefore "Value" in any type of rating is wrong. If buyer accepts "Custom order" or orders directly, they accepted the value of the gig and that is it. If they don't like prices, they wouldn't order. Why would be rating for that then?
Recommended to a friend... Why this? Some buyers just orders once and only once on Fiverr as they need just one job done. Why would then need recommended to friend option?
Seller communication level. In one hand that is fine, but if buyer orders straight forward gig, we deliver it within one hour for example, we didn't communicate enough? Check this for example. You go to the store, put what you want into the basket, go to the cashier, you buy things and your are gone. All communication was "Hello", "Do you need anything else" and "Bye"... When everything is clear, there doesn't need to be much communication as that is delaying delivery.
Service as described. Why stars here? There should simple be Yes or No.
There are too many things buyer needs to do after delivery and many of buyers are getting confused by it. Many doesn't leave a review because of it.
