g1smd, LOL... that advice will fall on many deaf ears here I'm sorry to say. But it's still good advice, I started doing that more and more last year, and am I ever happy I did. New traffic record this week for me...
But for many sites they do in fact need a lot of dodgy seo work done on them, for fairly obvious reasons [like why would anyone ever link to them in the first place?], so for those people, yes, you want to start paying more attention to matt cutts examples, they are very clear. And pull back a bit on the extreme stuff, gray and black hat stuff is always a game, those who play it well manage to keep their stuff below the trigger levels, and if they fail, they always have new sites to start pushing.
But if you need to be told what to do or not do, it's probably not a good idea for that person to try to play this game. Google will almost certainly catch you and your sites.
But nice posting g1, that's my new motto too, that's what I'm sticking to, all my clients who don't do it will fail I'm increasingly convinced, I've warned them so it's their problem if they want to keep playing that game.
