UGC works across every social media network. For example:
Facebook is an excellent platform to share customer stories in video format. Or even use UGC in your Facebook ads.
Instagram is another visual platform, making it best to use UGC that showcases your products.
Twitter seems limited, but visuals are worth 1,000 words, so use them. Share UGC product photos or host aTwitter chat to demonstrate the product live.
TikTok is where customers go to share their experiences, so seek and you may find dozens you can use (get permission first).
LinkedIn is for professionals, but they're people too and love great UGC. But instead of using it from customers, have your employees create it instead.
