Do Google Autofill and Instant Search affect Adwords' Keyword Tool reports?

[GlobeRunner]

While performing keyword research around the term "windows", I noticed the keyword "windo" gets 18,000 global monthly searches with .23 competition. Why is this? Do y'all think the Google Autofill and Instant Search features affect reports generated by using the Google Adwords keyword tool? For example, if a user starts typing a search query only to find the site they were looking for before they finished typing the search query, does Google count the partial keyword the user never finished typing into the Adwords Keyword report? I've always wondered about this. Sometimes I find it tempting to attack a misspelled keyword because of the massive search volume and low competition for that keyword.

I realize that many consumers may not be very good at spelling, and this may reflect a large search volume towards a misspelled keyword. On the other hand, I see this trend of high volume, misspelled keywords many times while performing keyword research for a variety of clients. Thanks.

i just read something about this actually. According to google, an impression only counts if the visitor presses enter or clicks off of the search bar or sees the results for no less than 3 full seconds. To google that counts as a search.

So "windo" could be a number of things. it could be that people typed that in and then pressed the search button or enter. Or it could mean people started typing "window" and clicked off after "windo". Or it could mean that they startted typeing "window" and before finishing they started to look at the results and stayed on the SERP for longer than 3 seconds.

hope that helps.
