Share 90% of your best content on each platform, then hint that the remaining 10% lives somewhere else. This respects platform rules while encouraging followers to find you elsewhere.
Here's a cool tip if you want to take people from a platform to another platform. So Instagram, Twitter, LinkedIn, they don't like it when you take people from that social media to other social medias. So the best way I found to do that, it's not tell people, hey, go here. It's that tell people, hey, I'm going to give you 90% of the content away in this post. If you want the other 10%, you can get more here. You don't tell people, here's the bait. You give people, here's the fish. And if you want the dessert, you can go to other platforms and get it there.
