If you join a ring that is full of people who are interested in what you create, you are likely to get the kind of visitors who may turn into buyers. If you create work that is relevant to many different rings, segregate it by type and create pages of similar work. Then join the rings that will send those pages interested people. Not all rings may welcome you as a member. The person who starts a given ring sets the rules for membership in that ring.
Some rings use voting to select who joins, most seem to be run by individuals.
