May I know should I use
1 domain for 1 offer OR 1 domain all offers?
(Hopefully I don’t sound stupid)
1 domain all offers
Does your domain name need to be related to your offers?
Why would that be? Your target audience is the average joe, so dont worry about it.
Pick a generic, all-purpose domain name. Like for example "www.currentoffers.info".
EDIT: Turns out currentoffers.info/ was taken. But you can pick a better one that is available I am sure.
Good to know! I always thought you’d have to run them on related domains. Very good to know indeed.
