Keyword Density falls in Black Hat SEO Technique. Write articles naturally without keyword stuffing. Use the keywords as many times as required. Don't overdo it. Write for users not for search engines.
I think it doesn't matter the point is to not overdo it, I mean keep your keyword density less than 6%, and make it as natural as possible, 3 - 4% is ok, the most importsnt on page factor is title
From what I know, the optimal keyword density for a webpage is about 5%. But this is not a rule. I would say that the best way to go about it is to do what feels natural. I think that if your articles flow naturally for the reader then you shouldn't worry much about keyword density. Try not to stuff your content with keywords that will make it seem unnatural.
can any tell me what is the best placement for these keywords? And how much is too much? When does it become keyword stuffing?
It becomes stuffing when your blog is so full of keywords that it begins to not make any sense to the normal reader. Like others have said, write for your readers and the natural density will follow.
If you have exact keyword density on ALL your pages it will look funny as well. Focusing specifically on google liking the site is less important than the visitors response. If people dig the page they will tell others which in turn ends up with backlinks and all of a sudden google loving you whether you are too dense or light on the keywords.
You can get away with lower keyword density if the keyword is very, very rare. Otherwise, stick to 3% to 7% keyword density.
