Hi Guys
We're about to launch a very large website for a flooring company and would like to find out more about _key word _cannibalisation - to put my mind at rest. I know Rand posted a Whiteboard Friday early last year about this topic and mentioned using part of the same keyword was ok to use.
All our keywords are specifically geared for "user intent" meaning each keyword has relevance and the content to back up the keyword. We've ensured the keywords are located within each url, placed at the start of the page title, h1 etc.
