What does the percentage mean on match com?

Your matches, whether in your Mutual Matches, in Match.com by Mail, or in Custom Search results, display a percent value that represents how well you match with the member in question based on our Mutual Match algorithm. Its the same percentage value the member sees if they view your profile.

How can you tell if someone is premium on match?

Find Connections on the upper toolbar in on your Match.com account page. Click on All Connections. Each connection displays a photo and lists whether he or you initiated contact. For example, the note may read, He winked at you. If the other member initiated contact, he holds a paid membership.
