With the current Roblox ad system you can run ads that all players around the world are able to see. This makes promoting your game, item, group, etc. very easy. Although, with Roblox continuing to grow and support more and more languages that does make room for some improvement on the current Roblox ad system.
What I’m proposing is rather than developers promoting ads to everyone around the world, they could target individual players by the language they speak. For example, if a developer’s game is localized for Spanish speaking audiences, they would maybe want to run an ad specifically for those players rather than everyone. During the process of promoting an ad, developers could have an optional drop down box to target one or multiple languages they want their ad to appear for those players.
Hope others agree, and of course if there are any questions feel free to leave them down below and I’ll try to reply as soon as possible!
