this tool sucks, it showed value of my one of sites as 155$. This site gets 250$ from text-link-ads sale (8/8 sold) alone and then I sell other links (Its PR7 homepage site with pleanty of high PR pages inside)
that tool doesn't have a clue of what it does. I wouldn't rely on it for a second. It doesn't even show similar results, or something that could be true even in a long shot. But this is just crazy. There is no site with a value of 0$. At least 15$ for the domain, or the work involved in the site, lol.
It says my main blog is worth $129,969 which amazingly enough is the sort of offer I'd actually have to think about considering.
