Hello, i have a site in the education niche. Lets say my site is optimized for the long tail keyword(example): ?distance learning courses Australia? Im ranking above the top 10 for this niche. So now I created a new undersite on the same website optimized for the new longtail kw: ?distance learning courses USA? 2700 words with a keyword density of 2,25%. But the words: ?distance learning courses? appear in this article 43 times with a kw of 4,57%. I mentioned it with other related long tail kw combinations, that?s why it is so frequently. If I insert ?company name + distance learning courses USA? the following results appear at google in order: www.companyname.td/distance-learning-courses-Australia www.companyname.td www.companyname.td/distance-learning-courses-USA So im thinking that google penalized the kw of : ?distance learning courses? with 4,57% although the site at www.companyname.td/distance-learning-courses-USA is optimized for ?distance learning courses USA? with 2,25%. May it be correct? Should I reduce the kw density of 4,57% ?
