Quick SEM Lesson: Is it [I] or [1]?

I was doing a little research on some video storage devices and I was sidetracked by an awesome looking new Sony HD camcorder - the HVR-V1. I love video cameras and wanted to see what they're going for in case I hit the lottery.

I went to Google and mistakenly typed in [Sony HVR-VI] using the Roman numeral I instead of the number 1. Here's the search.

Not one Adwords advertiser at all. Zero in my area anyway.

Correct that search and key in [Sony HVR-V1] and you get a completely different picture. Here's that search.

Check out the advertisers all trying to get your attention over there. You'd think at least one of the campaign managers for this would pick-up on this variation.

You have to look deeper these days to find these kind of fringe opportunities, but by consistently looking and implementing misspellings and such, you'll lower your cost per visitor across the board.
