Hi! How often do you change your rates?
in my case, as a new model when should I (when the time comes to) change rates for higher? what do you take into account? number of subscribers, frequency of private chats, mby rates of other models?
You should have a goal to strive for. Set the minimum limit on how much you wish to earn per day/week/month. The sum that you think is worth your efforts. Don't go cheap, appreciate yourself!
Compare to your current earnings if you not getting that money then raise your rates.
