What do you mean by you 'regularly submit your site information'. If you are just using it as a portal to advertise your site you won't be very successful. You need to have a strategy for your fanpage, a reason why it is beneficial to your fans. Try thinking of ways that you can offer them content that is exclusive to your facebook page and not available on your website. This way you will encourage sharing of your fanpage and entice more engagement and fans, and ultimately you can offer content that will lead back to your site. Just creating an account, posting the odd update and expecting your site traffic and revenue to bulge is a common misconception. You need to treat it as a proper marketing strategy and dedicate time to make it work - if you do this, it will be worth the effort!
