Keywords and Phrasing

[Justin Bilyj]

How many keywords/phrasing would you max out at, on a 600 page webpage?
article?

I know to keep the density between a 3-4.
Any help would be great!!!
Thank you

I'm hearing no more than 3% - so twice.

How many different key words (niche) per page should I use?
