It seems like in the long distant past, I read that money words like price, sell, and buy were bad for SEO. When googling for this I cannot seem to find anything other than some very old articles and typically they refer to sexual content or stop words.
I'm thinking along the lines of websites where price, we buy, sell are often used often bordering on key word stuffing. Assuming we aren't keyword stuffing, do we have anything definitive that indicates that money words in and of themselves can trigger SEO problems?
