So I'm just getting into making Amazon sites and I found a theme that I like, and I'd like to but the package for the theme where I can use it on unlimited sites. But what if I have the same theme on like 20 sites? Would that hurt me? If so, how? I do plan to test different themes and stuff but just in theory if this theme worked well for all my niches, would there somehow be another downside to using the d=same theme?
