Pick the right 5 competitors — not the obvious ones
The 5 brands you instinctively name first are the WRONG list. Their audience is too similar to yours; you'll just imitate. Instead pick 2 direct competitors (same product, same audience), 2 adjacent brands (same audience, different product — they've already won the attention you want), and 1 wildcard from a totally different category whose tone or format you envy. The adjacent brands are where the real ideas come from.
- Who are 2 direct competitors selling roughly your product to roughly your audience?
- Who are 2 brands selling something different to your exact audience?
- Who is 1 brand in a totally different category whose social you actually look forward to?
