Hi
maybe ask those who have reported the sale, to provide that info.
i know on sedo for instance, the commission charge differs,
promotion channel sale 20%
versus
parked domains originating thru sedo 10%
i guess it would be good to know for users of that platform,
if percent of sales came from internal searches, it could be used as marketing gimmick.
but then, that could speak negatively about type-in traffic or direct navigation sales.
a lot of folks just happy to get the sale and don't care where it came from.
but the question does raise interest, for that aspect of sales metrics..
imo....
