How to add domain to unbounce?

Hey, suppose I have the domain www.bestoffers. com and I would like to link it to unbounce.

Now, I want the domain to function like for example -

1. bestoffers. com/get-the-food-on-offer
2. bestoffers. com/get-the-phone
3. bestoffers. com/get-the-gadget.

Those 3 are separate campaign landing pages that I want to connect to my domain like that so when people visit bestoffers. com/get-the-food-on-offer, they would be taken to the landing page that I created for food campaign. Similarly, when people visit bestoffers. com/get-the-phone, they should be taken to the phone campaign offer.

How do I do like that?

Currently, the domain that I want to do like that is integrated into WordPress. So, how do I proceed from here?

Looking for some guidance on this.

Thanks in advance,
Mr.Sam
