Remember that most good directories require a real person to review your site and add your listing to the directory. This can take anywhere from a few hours to several months. Getting listed in the Yahoo Directory can take several years. Some parts of the Yahoo directory are rarely updated. If you pay a fee to be listed under the commercial area of the site you can substantially reduce the time it takes to get listed.
Some sites charge a small fee to be listed.
You should be able to tell if the site is just a scam or a legitimate directory. If you can t tell if the site is a good one or not keep looking before you pay to be listed. Once you review four or five of these sites you should be able to separate the good ones from the bad ones. If you find you're getting involved yourself in the site and find good resources and information, then that s probably a good one. Some of these sites allow you to pay for a top spot in the directory.
