What are the benefits of targeting one keyword phrase per page vs. multiple keywords per page

[EricVallee34]

What are the benefits of optimizing a page for one keyword phrase versus a group of similar keywords, like this one that Rand posted on another blog entry http://bit.ly/7LzTxY:

• Ted Baker
• Ted Baker London
• Ted Baker Clothing
• Ted Baker Mens
• Ted Baker Mens Clothing
• Ted Baker Mens Collection

Eric,

Rand's post really carries weight due to how search engines evaluate content relationships, and topical focus.  It's inevitable that your page, with enough unique content on it, will be found for variations of whatever core phrase you target, so you might as well integrate a couple or a few highly related relevant phrases.  Not only does it make sense in regard to ease of optimization, but the fact that you're integrating a few additional highly refined phrases just reinforces the emphasis on the primary phrase, while not coming across as trying to stuff that single phrase.

Search engines are very good these days at looking for those signals - the relationships of two topics.  Not just cross-page, but definitely on-page as well.
