Is there any country (other that US or targeted) with a lot of hits?
Once in a while one of my blogs receive like a thousand hits per day from China,
Ukraine or Russia and it's usually direct traffic.
So how you are advertising your website?
Direct traffic means mostly visitors enter the url and visit the website directly, so may be you are advertising in places, where visitors see your website, but cannot click them.
can be some bots sending requests to ur site... attempting to create load..
This may very well have to do with the Hummingbird update, or the phasing out of keyword data ("not provided"). I am seeing the same thing. I believe this data is skewed.
