Scott Perry, in his excellent free newsletter and site New Music Tipsheet, advises using more picture posts to drive traffic to your band's site and Facebook page:
I know studies can tell you the actual percentage of engagement among text vs picture posts, but I see it every day in my own feeds. When I post text-only to my Facebook feed, I get a couple of replies. But I post an intesting pic, and damn if the replies & likes don't go through the roof"
Start using Instagram or PicPlz or Flickr ASAP, link to Twitter / Facebook / Foursquare / Tumblr, etc. so you can post on multiple platforms in one step." (more...)"
Instead of just saying see you at the show tonight!" post a pic of the Space Needle or Portellos or Waterloo or Dreamland or In & Out or Waffle House, that tells fans in each town that you are there and that you get them. And THEN remind them of the show tonight by dropping a bit.ly ticket link in your post."
