In a post somewhere around here I read someone's note that correlated ovt number to anticipated monthly visitors. As I recall, the estimate was ~something like you could expect 10% of the ovt score for your exact keyword/phrase in a .com per month. Could someone comment on ovt vs. uniques. I would suppose that "actualdomain.com" ovt score would probably mean those people almost always land on the site.
In my experience traffic varies greatly. I've had domains that have an overture score in the 50's get almost no traffic and some with an overture in the teens that get ten uniques a day. Depends upon the source of the domains traffic. The overture score for domain.com tells you how many people typed in domain.com into the Yahoo and affiliated search boxes. Doesn't count Google and others. Still, even if someone types in domain.com in the search box and hits enter they usually do go directly to the page but to a link first. They could bail out there and never get to the page. Also, many expiring domains will have an overture score due to expired domain buyers researching the name before it drops. Obviously this would result in a higher than normal ovt score and, in the end, less traffic than expected.
