From a business perspective, in which social network are followers most valuable?

For some businesses Instagram and Tiktok are crucial. Others focus on LinkedIn and Twitter, and this is our case since most of our target audience is there:)

LinkedIn is more business-oriented and I think the majority of its users are into business one way or another. That's why it is preferred from a business standpoint. Yet, I'd like to stress that with some businesses, other platforms such as Instagram or Facebook are better.

I ask experts to share their opinion on which social network generates the highest ROI in terms of profit for small businesses when it comes to followers.
