Instead of focusing on one page per keyword, focus on one "idea" per page. The term "keyword" is misleading as a keyword is usually a phrase because rarely does a single word query result in a click-through unless the term is a brand. The best way to start is to "silo" your keywords into related columns within excel. If a term doesn't match the other words in a silo, it should be moved to its own. Then, instead of targeting one page per keyword, target one page per silo.
