Dont be lazy and Try Googling the term "list of free directories" I just did and found what you need.
What do you mean by "instant directories"? Directories that auto-approve links are to avoid. You can start from here: 150 Free General Directories, Fast Approval [01 November 2008]
Im also curious about what you mean by instant? Fast approving (a few days) or literally instant? I agree with triphp123, there really are lots of lists, simple search on dp will find you more than you can handle.
Check below given threads http://forums.digitalpoint.com/showthread.php?t=601628 http://forums.digitalpoint.com/showthread.php?t=1109840 Also don't forget to visit Solicitations & Announcements where free directories announce daily by members. DON.
I don't understand what you mean by the word "Instant". If you need a free directory list, I found this one a few days ago: http://seo08.com/free-directories/
You will find many such directories that 'auto-approve' the links, I keep away from those directories, because the other name for such directories is 'FFA'
Go to the solicitation and annoucement forum, most of the newly post directories are free and will give you link approval in 24 hours.
i believe i have posted a free directory service in the solicitation and announcement section.. you should check it out..
