I manage a few amazon affiliate sites and I'm working on building out my Pinterest presence. Is there a suggested way to structure you pinterest boards? I've been toying with these two options: Option A: Two boards, one with only my site's content and another with niche focused pins. Option B: A single board with combined niche focused content along with my sites content. In my case, I plan on creating a pinterest account per niche site and creating a similar board structure per account. Are there any other options or suggestions? Thanks.
