I think this obvious point is often overlooked. So in a way, no one else can give you a precise answer. For example, some people do outbound regularly, some never outbound. Some find first contacts on social media like LinkedIn or Twitter, others never use social media. Some prefer to get names that the brandable marketplaces will accept, and then sit back and let them sell them, or at least a few of them. Some like to sell to other domainers, and as long as your sell-through rate is high enough and you make a bit on each, that can work, depending on your goals.
Assuming you want to sell mainly to end users, and you can't or don't want to do outbound, I would suggest the following.
- Make sure each domain name for sale has a professional lander.
- Get them listed on at least one of the major marketplaces (Afternic, DAN, Sedo)
- Decide whether Make Offer or BIN is best. If you are doing BIN decide on the right price. Pricing is not easy, but I think most agree the right pricing is critical.
- Ask if you can in some way enhance the chances for your domain name. For example, by offering payment plan options.
- Don't spam people, but if you are active on professional social media, try to make bridges with the community that might have interest in your domain names.
Others have raised the question of quality, and I will not comment positively or negatively other than to say I think for many of us it is helpful to go through the exercise of what are my best 4 domain names and what are the 4 I regret having. For the latter, I would actually price them cheap at a registrar marketplace or on NamePros, or auction them off. Better to get hopefully enough to cover your costs than hold in a slight hope a domain name you no longer feel was a good acquisition. Re the best 4, even if you don't do outbound, develop a list of who might have interest in them, and some way to get them noted.
Finally, I might comment that to me your domains seem pretty varied. I mean WoodFlooring.net is certainly not a garbage domain name at all, but it is very different from say NudeModel.net! While diversity in niches is not bad in one way, in another if you are trying to develop contacts with the community in a niche it is very difficult if they are so different. I have gotten personally into too many niches and trying to go back to the smaller number I once had.
Finally, important to be realistic. Let's say you have domains that are typical of the entire set of domain names for sale by everyone in the world. The sell-through rate is about 1% overall perhaps. That suggests that on these 11 names on average you would wait about 9 years to expect one sale.
Finally, if you consider as many ways as possible, I think it will help you sell. You ask what has worked. I suspect while some sell only in one channel, for most of us we sell different ways. This year I sold one at Sedo, a few at DAN, a few privately, a bunch but only a few at decent values at two different registrar marketplaces, a few to domainers by responding to requests here on NamePros, a few in auctions here but not for much, etc.
