I'm just editing a website that has surfaced out of the sandbox and I'm very cautious now to remove the 'decorative text' and all that crap from posts. The posts were also keyword stuffed quite embarrassingly in some places in hindsight. This is especially since I've already had an adsense ban so really don't want to have my articles look like they've been deliberately optimized because even if that stuff wasn't strictly against the rules it might raise a flag to them to say 'yup we've got an optimizer here better look deeper for more dirt'. I'm trying to make things look as natural as I can on the front end and only putting the kw in h1, h2, h3 when it's appropriate. I'm skeptical as to how much that stuff did anyhow and especially now since the updates. Better to just plow it on the backend where noone is looking.
