Predatory conferences share many of the characteristics of predatory journals. They charge high registration fees (sometimes exceeding $1000) and they seek to make a profit by delivering a product that does not have rigorous scholarly standards.
OMICS group, BIT Congress, and Conference Series Ltd. have all been accused of taking advantage of scholars by advertising misleading conference offerings (Pai and Franco; Federal Trade Commision). In order to attract a large potential base of scholars, these for-profit conferences may advertise speakers who have not agreed to speak or have unusually broad topics.
1. Is it associated with an academic association or professional society?
2. Has the conference been run for several years? Is there a publication or proceedings associated with previous conferences?
3. Do any of your colleagues attend the conference?
4. Is it easy to contact conference organizers?
