Advertising Campaign Not Running

Hi Guys,
New seller here so sorry for any silly questions. I have set up a few advertising campaigns but they are not yet running. I am the only seller on the listings I am looking to advertise.
I’m not too sure why they aren’t running. Any ideas welcome…


When you say advertise, Do you mean sponsoring your listings? If so you have to be eligible for the Buy Box before you can use this feature. If you don’t have the Buy Box then it will work. I’m assuming that maybe you have been selling on Amazon for less than a 3 month period?
