So recently I have started working on my very first adsense site, and wrote some articles keeping density in mind. I used some keyword density checker plugin for wordpress, it displayed 2,83 for my main keyword, so I thought its good. But I have checked my page with the SEOquake firefox plugin's density checker and it said 1,44 for my main keyword, and 1,92 for some longtail kw I didn't even pay attention to. So the two tools display different density. How do I know which one is real? What tool do you guys use for this?
