Why do they have multiple listings? And it does make sense , there are different categories like love and relationships, finance, tarot , astrology etc. they create a listing for that category to be able to market their specialized skills. Not every psychic is an astrologer or reads relationship questions. It’s supposed to give clients better grasp of their abilities. Also, the more listings the more exposure as some listings like love and relationships have more psychics to compete with.
