Hey @transisto, @shenanigator here.
This is similar to what we're doing over at @tangerinetravels.
We send 1,000s of unique non-steemian visitors to Steemit every week.
You can check out that post to see more details. But in short, we're members of quite a few Facebook groups that are related to our niche. We post our Steemit posts there daily and have gotten pretty good at using Facebook's algorithms to drive a lot of traffic to Steemit.
