If you check out some of the suggestions below this though, you're likely to find some opportunities.

This should be rephrased to: “Satisfying the needs of the searcher in depth”. Followed by an explanation of how different types of content satisfy different needs, but each should do that in an outstanding way. In depth content is great when a searcher was looking for that and often when the intent is not clear from query and context (context as in the context in which the searcher does their search).
And your “Zombie Pages” way is a really a PROVEN way. 15-20 days after getting hit badly by Broad Core Algorithm Update, I sorted out the least performing unnecessary articles (around 50% of total posts) from the blog and deleted them.

Good point,The thing with this client is they wanted to mitigate the risk of removing a large number of links so high quality link building was moved in early before keyword research. So it is on a case by case basis, but defiantly a good point for most new clients I work with who do not have pre-existing issues you want to do Keyword Research very early in the process.
