I just spoke to a local SEO guy. He told me that a few years ago he would submit his clients´ sites to as many good directories as possible. However, now he takes a different approach. He lists his client site just to a few directories. Those directories allow their clients to fill their listing with fresh content often. For example with a news ticker. He says that he got far better results with 10 listings which get refreshed often than with 100 listings which never get refreshed. What do you guys think? We all know that fresh content is a key for good ranking. But would you really stay away from a good authoritative directory when it has no possibilities to post something new once in a while?
