Phaze himself.Where is the source from?
Yes, organic traffic is gold compared to DDL traffic, but still theres no harm in boosting your traffic by using DDL's. Even being listed on DDL's will increase your site's SEO - your site will get more incoming links from content-related websites.Instead of continuously focusing on DDL's to be your main source of traffic everyone should be focusing on optimizing their sites for search engines. DDL's are going to come and go, search engines aren't going anywhere.
I know I prefer direct & organic traffic over referring traffic any day of the sayear.
