We are wondering about this as well. Especially pertaining to keyword density. We have a niche ecommerce market and we sell basically four products and variations on those four. There are only so many ways to write about the same product and not sound spammy. Especially in the page title, description and keywords. Does Google know when you have a niche? Our key word density is between 30% and 40% because of this, but I don't see a way around it. Any ideas?
