Welcome to WebmasterWorld gullsinn.

I'm afraid that question is too general to get a decent answer. What does it matter if it's a Joomla, WordPress, MovableType or other site? What's good traffic?

i meant to say that there is no data in installed Jomoola portal and i want some suggestions that about what it should be?
in these days what kind of website the most people like to visit (no adult)

Gullsinn, are you saying you installed Joomla on a website but you don't have any content yet?

Normally, I find a niche and create content for that niche, and after reviewing the visitors' desires and needs, figure out what type of website to build.

As for good content, I doubt that people would share with you what their preferred niche is. (But then again, this is a great forum that could prove me wrong).

May I ask what your reason is for creating a website?
