For the past two months, I have been getting 200 - 300 visitors for the search term "bar". I can't figure out what engine it's coming from. The only thing is it must be coming form one of the "unknown search engines". Any ideas how to find out what engine is sending me traffic for this? Obviously I checked the big 3 already, other than AOL and Google Images "unknown search engines" is the only SE that sends enough volume for it to be possible. I get traffic from like 30 engines but most are less than 10 visitors a month. So wtf? I didn't even SEO for 'bar' nor have anything on my site about a 'bar'.
