Correct me if I’m wrong, but right after you’ve launched a blog, you’ll immediately go and register a few social profiles for it. With Twitter and Facebook being the first ones.
But registering these social profiles alone does not bring you any visitors. You should have a solid SMM strategy if you want to be successful. And most importantly, avoid common mistakes that most bloggers make as they are starting out. Just recently I asked 50 respected bloggers for advice on Twitter Marketing, which made me recall some awfully stupid mistakes that I was making myself early in my blogging career.
