Key word density

I have been reading a bunch of posts and have seen one person say that you should shoot for between 5-20% per key word. Another person posted not more than 7%. I was wondering is the answer to this question different for different search engines?

I also have a table that includes a large number of repeating key words will this cause me to be removed form a list?

Thanks for the help

I have tried some 20% and above keyword density experiments.....I can't sense an upper limit.

Seems I'm never punished for that particular variant in any search engine.

However, since there are so many keywords in most contexts to do a good job with, I also don't see the point of extremes as they (perhaps) waste valuable digital space and the mind time of future perceivers.

As, for examole, in my homepage....

You can see that I have lucked out, at least for now, in certain keyword combinations.

I see a possible value in the 8 keyword url because the url forms its own anchor text even when standing alone. Simple logic. I have also seen and stated that url keywording with hyphens is sort of spam limited because we can only have 63 digits to use or whatever the current limit is.

Godaddy.com seems to be trimming my long url experiments lately and they're not say why....hmmmm.

If you have further questions or insights I will do my best to help.
