I currently have a webpage that's been bouncing in positions 4,5,&6 for a certain keyword. I went to check the keyword density today and realized the kw only appears once on the whole page of 2000+ words. I have edited the page to include the kw in the first, middle, and last paragraphs. Appearing once in h2 tags. I'm not doing any linkbuilding right now either. I'll post back here when/if I see any changes.
