Ratings received, obviously! Don't know about other platforms, but UpWork shows you this on the project's sidebar: http://i.imgur.com/661gveO.jpg http://i.imgur.com/661gveO.jpg Every line is important: if (s)he's verified, how many stars there are, what's the hire rate. Usually you should aim for at least one 4 (or more) rating, at least one job posted with 100% hire rate.
