I've recently taken an interest in website directories only from the stand point that I wanted to learn something new. I have a few questions about them, that kind of confuse me. 1. How do they gain PR just by linking to other peoples sites? Do they build links to other directories as well? 2. I imagine that a lot of directories build links to other directories via the recipricol links, am I on the right track? 3. You can't really rank a directory for a specific keyword can you? I mean I guess you could if you had a blog page or w/e but I imagine the majority of link directories are just looking to sell spots. 4. Are link directories a good way to get backlinks currently? 5.Can you make decent money still off link directories?
