I've suspected that many writers make a number of mistakes related to blogging. Julie DeNeen at Fabulous Blogging discusses just one in Most Bloggers Think About Social Media the Wrong Way.
What she's talking about here is using blog posts "everywhere, multiple times, until people are so annoyed they start unfollowing you." A lot of people have a lot of the same friends on Facebook and Goodreads
and some of those same people are following them on Twitter, too. So using the same blog post everywhere can lead to a lot of repetition. Writers, in particular, have to be careful about this sort of thing when we're doing one of those "my book got a wonderful new review" posts. People receiving these messages multiple times can feel they're getting a hard sell. You don't want to come across like a telemarketer trying to get homeowners to switch electric plans.
DeNeen describes ways to treat the same material in different ways for use in different places. Her plan reminded me of advice I used to read for freelance writers. It sounds like work, but I suspect that it's the kind of thing that you get used to doing and then it goes fast.
Please excuse me now. I have to go look at that Google plus tutorial Deneen linked to.
