WHAT´S THE DIFFERENCE BETWEEN AUTOMATIC AND MANUAL WAY OF SENDING AN AD BUDGET
When Publishers create an Ad Space, they must set the Price they want to charge for it.
If they choose to set AUTOMATIC way, then that Price will be automatically sent as Ad Budget to every Ad Request that matches the criteria of that Ad Space (like Demographics, Category, etc).
But if the Publishers set MANUAL way, then no Ad Budget will be sent by default to the matching Ad Requests. Instead, Publishers will be able to manually adjust the Price they may want to customize for that particular Ad Request or Barter or Affiliation Proposal.
Publishers will thus be able to make exceptions to the Price they usually charge for a particular Ad Space if they wish to do so.
