You didn't mention repeat visitors who arrive via bookmarks or typed-in URLs. Such repeat visitors can be worth more to publishers and advertisers than people who are searching at the early stages of the buying cycle.

For more on search vs. purchase behavior, see the PDF summary of DoubleClick's "Search Before the Purchase" study, which you can easily find with a Google search on that title.
