Targeted Keyword in the document

[Frozen_Fry]

Hi, I write long articles 3k and 5k words my question is that I read in Moz article not use your keyword more than 15 times is also apply for 3k articles ??? and if yes than my second question is that I used my targeted keyword in heading also include in 15 times ???

In regards to keyword targeting the first goal is to write in a way that is natural for the end user. You shouldn't focus too much on trying to include your core keyword a specific number of times there isn't a hard and fast rule for that.

What I would look at instead is keyword density. This will take into account your longer form articles.

But you shouldn't focus too much on hitting certain keyword targets but focus more on producing great content that solves a particular pain point.

Hope that helps some.
