I have to say Facebook as it what really lifted me off the ground with getting my online business going BUT now I feel it is time to move on to Instagram. I feel there is more potential there especially if you want to build brand recognition pretty much overnight.
Yeah, Instagram can be a great way to get traffic if you can get some posts to really take off. Great way to gain visibility.
I believe that Utopia becomes very popular today and I can call it a social network as it includes messenger, email, browser and many other features. We hadn't seen anything like that before.
Depending on the business, nowadays Facebook doesn't show posts for a lot of people without paying for them, so I would choose other most popular media - Instagram.
I think for now the best solution is to combine Facebook and Instagram. The first one is more reliable for business promotion and the second one helps to create a brand, I completely agree with you here. Unfortunately, this tactics requires investing much time, effort and money if you want things to go fast.
