Let me give you an example of why your site design is poor.
Porn Land Videos
Index page. Just text. No pics. Very very very very basic. Also very hard for me to read (dark red on black).
Tour page.
No vid samples that I can see? Yey is a vid site?
It should have a few secs of vid from each film (say in flash) for me to see what your content is like and make me want to see more.
I pressed on the thumb as it says 'download this film'. At very least I would expect to be taken to the sign up page, or better still a page where there is a sample from the film plus a few pics from the film.
It seems to only have one tour page.
Also is the content exclusive (did you shoot it)? If so, make a huge point of that. Its one of the big selling points is that you shot it and its exclusive.
