incrediblehelp, you are right, dont care about KD but still search engine may seen this as stuffing. I have about 25 category pages and i am using lab coats again and again. I know its better for surfers to understand what it is but i dont want to take any risk as search engine ranking is key. I was trying to submit one of my site to yahoo paid inclusion and on my home page I describe what I am offereing but yahoo people said you are stuffing your keywords. I told them its not stuffing but describing what I am selling and as of today I am still facing the same problem. Here I have to mention this also that I am #1 on yahoo for my main keyword for past 3 years for that specific site.
