To your above list, I'd add: 6: Factual knowledge / information I find myself quite regularly searching for factual information related to gadgets / devices / machines etc. that I want to find out about. For example; 'Is car AAA easier to find spares for than car BBB?', 'is camera AAA better constructed than camera BBB?', 'what are the things to look out for when buying a second hand CCC? Increasingly, I find that, no matter how I couch the search terms, I end up getting given pages of results which are sites, trying to sell me the thing I referenced in the search. I'm lucky if I find the relevant info in the first page of results. Often it'll be on some discussion forum which crops up way down the list. I wish there was some way to tell a search engine "I'm not interested in sites selling the thing I'm asking about. I just want information" so that the actual nuggets of genuine info would receive a higher priority.
