Has anyone got any evidence or hunches that optimal keyword density is different for different keywords. Matt Cutts has talked about how different keywords are affected by update freshness. i.e. a news site that gets updated every 5 mins will benefit more than a dentists website.
But would optimal keyword density fluctuate too? I suspect it does but don't have any real hard evidence to prove it.
