Hi
to me, there aren't many advertisers for the keyword
as usage is limited to explaining what a college professor is, how to become one or professor jobs, etc
additionally, one doesn't know whether the professor is an associate professor, assistant professor or if they have specialized area like research professor
but i guess that in itself, would be enough to make some content on a mini-site.
universityprofessor.com is redirected to parked page and has more search volume than college professor
collegeprofessor.us is available to register
collegeprofessors.com has BIN price of $9999
universityprofessors.com has BIN price $5k
if you received 6 figure offer, then i certainly would have taken the cash.
imo...
