If you are a UK Whatnot seller, you might be making a common mistake with your social media approach. Many sellers treat social media like a notice board, posting announcements such as "Going live at 7pm tonight" and then wondering why no one shows up. The truth is, social media is not a bulletin board. It is a discovery engine. Every post, reel, and story should aim to spark curiosity in complete strangers, encouraging them to find your Whatnot profile and join your streams.
