What should I do about my puppy’s constant barking?

Hey everyone,
I recently got a puppy and I'm struggling with one issue — constant barking. It happens randomly throughout the day, sometimes at noises outside, sometimes when he wants attention, and sometimes for reasons I can’t figure out.

I am not sure whether I should be training differently, ignoring it, redirecting, or doing something else entirely. I want to handle this the right way early on so it doesn’t become a long-term habit.

What strategies worked for your puppies?
Any tips, training methods, or mistakes to avoid would be super helpful. Thanks in advance!
