Don’t overdo memes/linkups.
Well, you shouldn’t unless that’s what you’re blog is about, anyway. This depends on how often you blog, if you blog 3-4 times weekly, doing a linkup once a week is OK. If you blog every day, doing one 2-3 times is probably fine. I’ve seen some people do linkups, and then write personal posts on the same day, and I think that would work as well. You could also pick one day of the week to do linkups.
