When writing an article and aiming for the usual 3.5% KW density how do you work out the ratios if your keyword is multiple words for example
A 100 word article with a single keyword like "potter" would need the KW mentioned 3.5 times roughly
A 100 word article with a long tail KW like "harry potter hogwart's castle" would need to be mentioned only once or 3 times?
Does the google algorithm count the a long tail keyword as one word or actually count the number of words included?
It's been troubling me because if i follow the rule to the letter and put the keyword in 3.5 times per every hundred and it's 800 words long that would entail me using it 28 times in 800 words which can't look natural. That's actually 17.5% the articles body text.
Thanks in advance!
