At the end of the day, why don't they just keep it simple.
1-5 * and a comment. You can search by the star rating and read the comments to get a vibe. Simple.
As a seller: I just want a simple rating feedback mechanism if I choose to do so. I don't want to answer lots of questions (twice) and mark emoji buttons. As they say an unhappy client is more likely to go to the lengths to rate you bad, than a good one good. This just aids any disgruntled client (for whatever reason).
As a buyer: I just want to know that I provide the service I advertise - if you don't like it fine mark me a 3*, if you do then great mark me 5*
If I was getting 3 out of 5 stars, I could look at the comments and then think "hmmm I need to up my game on these repeated points". If I get 5 stars I think "I must be doing well".
But with all these secret squirrel internal scores, random algorithms, and stretched metrics - it just adds confusion and just makes the whole process incredibly difficult. Then add to the Fiverr don't share their workings out on things. Just makes the whole thing miserable.
