I've read a few posts that suggest if content is good enough, you'll find ways to share it w/out the easy buttons. While I agree in theory, I find it foolish to presume - not to mention you always lose out of the credit and the ability to track those metrics. Agree w/ all of these - be clear on who and what, give credit to guest authors, make sure the post is readable. Another few mistakes I see - no images; no links or worse IMO, links only to yourself; the biggest of course, no point and purpose to help achieve business goals. FWIW.
