Just to back up what I was saying.
Take the keyword computers
Apple ranks for the keyword computers.
It is a very competitive keyword. But apple does not use the keyword in their text.
Their title tag says
<title>Apple</title>
There keyword tags says
<meta name="Keywords" content="Apple">
and W3 says

While all the stuff in the site is good to have it is not a must when it comes to ranking a site.
Just my two cents. (-:
