I'm trying to get a better handle on good SEO. After reading a few articles on LSI, it seems like LSI would encourage keyword stuffing. While maybe not using the same keyword exactly, but using lots of synonyms. I.e., if LSI is about creating a matrix of overlapping titles and words, wouldn't that by the very process point to high keyword density? Sorry, I'm sure it's more complex than this, but if LSI is important, I need to better understand it. Thanks.
