Metrics rarely serve as an obvious pointer to the correct course of action. Rather, they serve as a valuable check against your thoughts and intuition. If you create what you think is an amazing bit of documentation, and sure enough, it's one of the most popular pages on the site, perfect! If it's not very popular, maybe no one can find it, or maybe it's not as useful as you thought. Deeper investigation might reveal a major flaw, a minor tweak, or a reasonable explanation that requires no change at all.
