I was reading John Battelle’s The Search , and realised: We don’t sit down on the computer and say, “Let’s do a search”.
True. We want to get something done. We know it’s out there somewhere. We search.
So every search on a search engine is a commercial opportunity. Contrawise, every site must let people to do what they want to do on the site.
Think… What do people want to do when they’re on YOUR site?
