Fascinating and great tips!
1. Build your audiences on Facebook and Twitter so you can drive all followers to your Medium article simultaneously when you hit “publish.”
2. Place paid advertising on social networks.
3. Build your following on Medium and follow other people, too.
4. Share parts of your story on Twitter with text shots, which can give your stories 3–5X more engagement.
I don’t feel like Medium’s text shots work right for me on Twitter when I follow the instructions described in that link. So I just screenshot (using Screenshot Captor), because including the image definitely seems to improve engagement on Twitter.
I’ve never tried the paid advertising route, but I could see how using steps 1–4 together could drive engagement way up and help a good story go viral.
