These days I can't search up anything SHINee on YouTube or social media without seeing boysnextdoor ads.
So I got curious to see if I get their ads when I search for other SM boygroups like NCT, exo or suju. But nop.
It seems like their ads are targeted toward fandoms of groups with similar concepts. 🤔
I always thought ads are more general but in this case I guess they are targeting specific fandom.
