Not all advice is good advice. That doesn't mean you shouldn't listen to it, but you definitely should take it with a pinch of salt.
I've read SO much blogging advice and countless blogging tips posts, but I don't always do what they tell you to do (ooooh). What works for someone and someone else's blog may not work for yours. And also outright copying someone's blog is never going to end well either. So rather than repeat the same advice over and over again (it's been done to death a little, just do a quick search on blogging tips on Pinterest and you'll see what I mean) I thought I'd do the opposite, and tell you some of the worst advice I've either been given or read elsewhere.
