Audiobook pre-order campaigns: Worth it?

I’m considering running a pre-order campaign for my upcoming audiobook series (fantasy trilogy, all volumes releasing simultaneously). I’ve done this successfully with ebooks but never with audio.

– Do audiobook pre-orders help with platform algorithms?
– What incentives work well for audio pre-orders?
– How far in advance should pre-orders open?
– What marketing tactics specifically work for audio pre-orders?
– Any technical considerations I should be aware of?

If you’ve run successful audiobook pre-order campaigns, I’d appreciate hearing your experiences and results!
