I am trying to decide what to do with some domains I have owned for a while. The options I know of/am considering are: auctioning them off, developing them into an income source (blog, ad parking space, etc), having someone else develop them into a traffic generating source and selling or monetizing. Does anyone have experience with Web development and/or traffic generation that can help me organize my thoughts on this. There are lots of suggestions/ideas online of course, but I don't personally know anyone that can help me with this right now.
The domains are: 3dprinterbasics.com wineknowledgehq.com earlymortgagerepayment.com
Thank you!
