Title Contention Issue

Hey….looking for some advice my fighter is 31-0 in the bantamweight division. I always try to make fights on the week the new rankings appear in my inbox.

I’m currently ranked
1.
16.
14.
19.

And 7th globally however have been doing my best to protect my 0 so haven’t been choosing the guys right at the top of the list all the time.

Is there anything you guys can suggest to rank up quickly?
