Does Publishers Put Ads?

Does the publicist put the ads on your game? Or u do it before sending it

 

Don't send ads to the publisher. If they accept your game they will tell you which ads to place

 

Usually you do it yourself, you are the developer. Some publishers though might offer to do it themselves.

 

Usually you as the developer will put the ad ID's into your game. They will provide you with their keys / ID's for what will be the build that is submitted to their account.
