Hyperlinking keywords to their articles

quick question to a SEO pro

ive got my main keyword and associated keywords, main keyword is exact domain and other associated keywords making articles for each, should i hyperlink the associated keywords to its respective article every time? in one 600 word article i have around 60 keywords that have articles and alot are repeated, do i hyperlink every one of them or just once or what?
thank you

I would recommend linking to one particular keyword only once, and not more than 3 links linking out of an article for total keywords.
That is just what I would consider best without looking spammy.

yeah thats what i was worried about, also what is a good keyword density? it feels like im using too many keywords in an article

If you think it's too much, it probably is. Keyword density doesn't really matter unless you're overdoing. Can you use synonyms? Does it read naturally? Do a rewrite and pay more attention to the mechanics and readability of the writing. If you're focused and on-topic, it will show to readers and search engines.

in terms of readibility its perfect, very good flow and very on topic, i was just worried that a robot crawler wouldnt know the difference,

btw is there a difference if i use the joomla or wordpress or bsaic html for the site?
