The difference in a business and personal accounts varies from site to site, but in general you usually gain access to analytics as well as other tools to use. I know on Pinterest you are able to do more pinning of products and promotions without getting marked as spam- though the threshold still seems pretty low, as well as gaining access to the analytics. On instagram you also get access to analytics for sure as well as swipe up links and verification after so many followers. That’s about all I know!
