I have seen in my own experience, being penalized from as little as a 1.5% density with a few internal exacts almost immediately. Though I am noticing cases where a lot of sites with up to 80% exacts in google are ranking for 7 months to a year, primarily with shit links. Were talking like 300 exact links, not just a couple here. What is the reason for these not getting tripped by the anchor algo and dying within a few weeks? Or what could the reason be?
