Hi, One of my site is doing good already and i am thinking of starting a directory on sub-domain. mmgurl .com is my website ... already have thousands of backlinks. Already have PR3 and soon to be changing for big PR. Do you suggest to start a directory on it's sub-domain? If yes then what's the worth of starting it? Thanks
No problem doing it some of the best directories are sub-domains ex. dir.yahoo.com You will get PR leverage from the main domain, sub-domains are best for niche directories.
