Things to consider when searching for conference opportunities:
Another thing to consider as you seek conference opportunities is what type of presentation you will give. Would you rather give a poster presentation or speak? For those new to speaking, a poster presentation may be less stressful than standing up in front of an audience at a podium. Some conferences allow you to select which type of presentation to give; other conferences make the decision for you. The presentations are usually short.
Predatory conferences are run by companies whose only goal is to make money, not to provide an actual learning experience for their attendees.
