The choice between Instagram Reels and YouTube Shorts depends on who you want to reach. Reels are better if your audience is younger or spends more time on Instagram. They work well for lifestyle, fashion, or short creative content. YouTube Shorts are better if you want longer watch time and a mix of viewers from different age groups. Shorts also help grow your main YouTube channel if you post longer videos too. Both platforms reward consistency, so pick the one you can post on regularly. Do you think short videos work better for attracting attention or keeping people interested for longer?
