Are sites of institution or companies a competition?
Seeking experienced marketers' opinion:
Let's say you want to start an affiliate site in the niche of Guitar Playing (Just an example).
In the competition analysis, you found there are sites with domain authority (according to SEMrush checker) 30-50-ish. And they are mostly music schools site with a blog section. There aren't too many blogs or affiliate sites.
Is it still worth digging into this niche and create an affiliate site where competitions are mostly schools or product companies' sites?
