Editing What links here

'''What links here''' or '''WLH''' is a [[standard link]] in [[MediaWiki]] and some other [[wiki code]].  Off to the left in the [[Develop Wiki]] for instance you can see "[http://develop.consumerium.org/wiki/index.php?title=Special:Whatlinkshere&target=What_links_here | what links here]" - click on that, and you will see what links to this page you are reading right now.

:[[MediaWiki]] carefully differentiates reference to [[redirect]]s but lumps all those usages with variant [[anchor text]] together.  Thus, disciplined use of [[redirect]]s can make '''what links here''' much more useful to quickly figure out the conceptual organization of a [[large public wiki]].  However, overuse of the "[[pipe trick]]" obscures the actual nature of these references and makes the overall function of any page very difficult to quickly determine.

How should [[Consumerium Services]] exploit these facilities to improve the [[Publish Wiki]]'s usefulness?  What role does '''WLH''' play in [[Consumerium buying signal]] and [[point of purchase]] activity?
