I have been trying to get listed in DMOZ for just over 3 years now, is there something wrong with my site? I Try once every 6 months. I really would appreciate your feedback. http://www.justgoodcars.com .
I would offer it again and then forget it, there are usually a lot of sites that are good candidates for that category. Re-offering will not do any good after that.
The category you submitted to is one of the worst for attracting spam submissions. I've spent hours and hours and hours just deleting bad submissions in that category. It's no exaggeration to say that an editor can devote 5 hours reviewing submissions to that category and not list a single site. I know, I've done it. Your site can't be listed because it doesn't have any classified ads that I could find so it would be deleted as spam. When I browse the site I see no ads, and when I do a search it takes me to other sites. Your site isn't listable in DMOZ.
When you put it that way it makes perfect sense. The system is set up in such a way that each make/model has its own unique website but they are as you can see by the design all part of the same site to create familiarity across the network. If I were to show classified adverts in http://www.justgoodcars.com/used-cars/used-lamborghini.html for example, would that make a difference? Also would you suggest I submit my 1000 niche websites instead, for example http://www.justf150cars.com, for Ford F150 vehicles. (Over 20,000 F150 cars for sale) We have over 1 Million vehicles for sale worldwide. I personally feel we should be on there, but would be more than willing to correct what ever needs to be done to get listed in that category. Thanks for your comments they are much appreciated .
Definitely DO NOT submit all niche websites. I can't offer you much more help than that, but submitting all those websites would most likely get them banned.
