Although it is the longest, I would go with phplinkdirectorytemplates.com Search wise, that is what I would type in google to find a template for that script.
Are you serious ? If you don't have any SEO goal in mind go register another domain I can't imagine anyone type these URLs If they don't bookmark you or find you from a search engine i don't think it will be any traffic
Im going to use PremiumPHPLDTemplates.com. Fits the site well. Though, thank you for your comments. Unless do you think I should get something like 1phpldtemplates, or a1phpldtemplates, etc?
I just registered phpldtemplates.us - These are the exact keywords I want to optimize, but I really want the "store" on a .COM. How should I go about getting this name ranked in search engines? Should I just use the .US instead of a .COM? Thanks for the help everyone!
