Never spam your feed. I follow some people whose work I genuinely enjoy but boy when they post 40+ times a day I have to unfollow. I sometimes post a bit much all at once when my son goes down for a nap (generally on top of my head or chest). But overall I really try to space out what I have to tweet, tweet about. Nobody likes a noisy bird fellow tweeters.
I don't just promote my work. I also share jokes, stories and personal photos. I dislike when a twitter user is only selling me stuff, links, vlogs, promos. I want personal interaction and so I give that too.
I don't just want a click on a link from social media, I want engaged readers who really care about what I'm writing and love following along on my journey. One of my favorite things about the blogs I have read for, sometimes years, is finding a genre I want to know more about along with the connection of following a person on their journey. Don't let your blog and twitter be just a bland list of posts. Engage and write from the heart.
