You can increase your adult / mainstream traffic just by uploading videos on youtube.
How can you do that ? Well there is a simple process:
1. Search for videos
2. Watermark them
3. Add a good title, description, tags.(In description you can add your site url)
4. Upload them to your account
5. Keep the uploads under 50 per account
6. Repeat the process.
Now you'll ask yourself after you've done these steps. "Hell it's alot of work, I can't do it.
Isn't there a tool that can help me ?".
Yes there is, I just made the first release, check my sig.
Cheers!
