Evidently your test demonstrated people can spell Harry Potter. Or did it show that a lot of people are looking for Harry Potter content? By the same token, were they spelling anime incorrectly, or were not very many people searching for it? Was the key word used to reference an image, a site, or a tutorial? Search engines are used extensively for finding tutorials, but not so much to find renders. Sites are usually found by word-of-mouth, and grow through first impressions and level of activity. I'd hate to guess what Google has spent researching this. I'll bet there's a lot of information out there on how to build site traffic, though. ;)
