I'm using Keyword Discovery (nichebot's platform, I think) to look for good keywords around a certain subject and I got a very strange result. I'll explain with a fake example: I play around with "cars". Keywords tend to have very low KEI, but I noticed that a combination of keywords has a unusually high number of searches and very few occurrences (so a high KEI). One of the keywords has a typo, for example: cars and chrysle (last letter dropped) It looked fine to me at first, I assumed that many people commit the mistake when searching but few webmasters do it in their websites, so I had the right keyword to build a site on. However, the strange thing is that this combination appears with WAY more searches than the 'correct' one: cars and chrysle: 20,000/day cars and chrysler: 3,000/day Furthermore, when I look for this weird combination in overture it shows no results. So now it seems to me that is is some sort of artifact, but I can not guess how it happens. Is this something usual?
