Where do I find my airdrops?

Could you please advise me on how to locate my airdrops? I've been hearing about this cryptocurrency distribution method, but I'm not quite sure where to start looking. Is there a specific platform or website where I can check for my eligible airdrops? Also, are there any prerequisites or steps I need to take in order to receive these airdrops? I'm quite new to this and would appreciate any guidance you could provide. Thank you in advance for your help.
