There are two types of Social Influencer Ads: Meta Social Influencer Ads and TikTok Social Influencer Ads. Ads on Meta platforms (Facebook, Instagram) are advertisements that are displayed through the influencer’s account for an advertiser. They don't appear in your feed but show up as "Sponsored" in the Instagram and Facebook feeds or as stories.
TikTok Social Influencer Ads, on the other hand, may or may not appear in the TikToker's feed. However, the ad is still displayed on behalf of the influencer, similar to Meta ads.
