Play my game? I just think you made an incorrect statement. I'm not attacking your credentials. And, the two links you just gave proved me right.
Your first one was a forum post where most of the posts where saying density IS important.
Your second link had this quote "I’d recommend thinking more about words and variants (the “long-tail”) and thinking less about keyword density".
No where did I see anything that said it is 100% of no effect, like you said.
So, to all other readers of this forum, density may not be as important as it used to be, but it's still a factor in
SEO. And, to the first post of this thread, I would be careful not to overuse the same keywords, but two times in your title is definitely okay.
