Each bot is built to target one targeting group. If you want to aim for different targeting's at the same time then you need one bot for each targeting.
How you want to divide the targeting groups is up to you, it can be anything from geographical where each bot is targeted towards a specific area or to bots which are each targeted towards specific titles.
You can find the number of bots available in your plan in the agreement you signed with us. If you are unsure then feel free to contact our Support.
If you want to purchase additional bots then you can contact your AM/CSM or email@example.com.
