Different demographics, different intent, and different mental context all play a factor.

  Not a statistician by any means, but could traffic source be a factor that's evaluated alongside conversion by a bandit algorithm when calculating the chance to show a particular option? Or other factors as well (detected device capabilities, users location, etc?) These could just be weighting factors so instead of a single % chance per option, every time there's a successful interaction the victory is spread across the factors for that option. New users could be shown the option where the chance for each option is weighted by the factors they match. Is this a valid approach or would it introduce some kind of selection bias?

    Yes, of course. You can use a contextual MAB and include the traffic source in the context. Contextual MABs are much more complicated and expensive to implement though.
