🚫 All targeting settings at once You can't use language, channels and topics at the same time.
⚠️ Topics + Channels If you choose a topic for targeting, you can't add channels to it as well. But you can exclude certain channels from the topic.
⚠️ Language + channels If you select language, you cannot add channels - the field must be empty. In this case you can only add channels to the exclusions.
✅ Language + Topics You can specify language and topics for targeting (to show only in certain niches). You can specify a language and exclude some undesirable topics from display - then targeting will be as broad and inclusive as possible.
✅ Channels only Specific channels you have already selected or competitors' channels with 1000 subscribers or more. You can use targeting on your own channel to buy placement from a competitor.
