Proper way to eject a hard drive?

I have 2 external usb 3.0 seagate hard drives and was wondering if theres a recommended way to eject them when theyre not in use. I normally just go to the settings,hit eject,wait about 30 seconds then unplug the usb from my laptop and then unplug the power cord. Is there a better/ safer way of going about this or is this perfectly fine? Dont want to cause unnecessary wear in case im doing something wrong
