Follow the ad spend. Beauty, skincare, food and drink, home, wellness and tech buy the most UGC because those brands run paid social nonstop and burn through creatives fast. Pick where your real interest and a real budget overlap. A niche you can talk about for years beats a trendy one you will quit, so check who is already running UGC ads before you commit.
Where the UGC money is

Pick proven categories

Match interest to budget
Pick a lane you can sustain. Burnout in a hot niche pays nothing.
Check demand first
Look at who is already running UGC ads in a niche. That is your green light.
