Adext AI finds the best audience for your ads by automatically exploring different demographics. If you try and exclude too many of these demographics then Adext AI can't optimize efficiently, for this reason the number of excludes is limited.

Even though we limit the number of demographic exclusions, it's important to know that Adext AI will automatically find which demographics to exclude (by dedicating none or much less budget to them) based on the conversion activity of each demographic to arrive at the best audience for your ads.

Often times Adext AI users are surprised that some demographics they wouldn't have considered actually do really well and are worth creating ads for.
