The best method to name a directory really depends on your focus. Many big companies don't think of what their keywords should be. They simply brand their company name and advertise with it. Obviously, SEO is a rather small way of advertising method for them. So, if you think you can make your domain name known to millions via agreesive advertising/marketing campaigns, such as advertising on TV, you don't need to worry about SEO too much. Just let people know your company name. If you think you need SEO to promote your directory, then trying to appeal your unique company name may not be so effective because people usually not search for a company name to find the site. They use general keywords + niche keywords to find your site. So, ______ Directory.com is a way to go in many cases as you might have seen so many others just like that. Or you could do Directoryof_____.com Just a suggestion though
you can use absolutely anything. I recommend something that people remember easily and know how to spell.
I'm currently in the url___.info mode But I may go into another mode pretty soon but ain't gonna say because its virtually untapped
Use number in front. Or make sure the first letter is a "a". "alive-", "aviva-", "alltheweb-" So tha when someone browse for a directory, yours will be first.
Pick the brandable ones recommended by blogmaster then follow britishguy's suggestion. http://www.site-sift.com IMO, one of the best directory name. Yeah, just like alphans.com
