Keyword Density, I know is a very sore point here on WebProWorld.

I have written some marketing pages with a keyword density of around 4-5. However, once I add the footer onto the page, I suddenly have keyword densities of a 9-10%.

I use the keyword cloud checker on webconfs (Keyword Density Checker - Keyword Cloud). They take out 2 letter words and removes stop words.

I expect contrasting opinions here, but what keyword density should I be looking for - should it matter that the density flies up when I add the footer (the site is built in asp), and what keyword density tools does anybody else use??

Thanks!!
