I think using different pages could have an impact, but you might start competing with yourself. Using different pages for the same thing might enter murky territory in Facebook policy. I don't think using a new page is a clear-cut solution: here are 2 main variables I would expect from using different pages: 1. Different FB ad history means different preference in FB algo (good or bad). 2. Users might react differently to a different page name/profile pic (good or bad. I'm pretty sure if you're using the same pixel for the ads across any page/accounts FB is easily aware of that, so I think the overall issue persists. I would never recommend multiple ad accounts: less control, more overlap, less transparency. FB has to choose/prioritize who to serve impressions to between any ad sets that target the same users, so you won't see the actual effect, but one will be prioritized over the other. If you're targeting the same users across ad sets, campaigns, or accounts it's the same issue. Overall, I'd recommend stop fussing with silly setup baloney and focus on creative/ad experience and landing pages/conversion flow that will actually move the needle.
