I ran WebCEO and its analysis of my pages says that I am 'spamming' my keyword and that anything over 11 repeats on a page is auto-filtered as spam and will consequently kill your ranking. I thought G looked at density not repeats. Does anyone have any input here, I find this report hard to believe. Perhaps this is based on analysis of a sample of the population of all webpages and found that the top ranking sites only see 11 or less repeats?
