Im new to the game of facebook, actually i dont even use it for personal pages, so i have a question. When you create a fan page can that page just get auto traffic from facebook and search engines without you doing much? Like if its of a hot niche and you use the right keywords, could people just find you.

It is possible to get instant traffic to your fan page by using a trending topic (something most people will support). Chances are you won't get enough fans to really go viral unless you get lucky and get a link in a press release. You'll get more fans buying status updates or fans tbh.

I would like also to know some good tactics.

I made a post today with a few tips, you can check it out here
