Fans like to talk to connect to celebrities on social media if they are self-managed. Getting an agent or a representative to manage your Page, with third party updates like ‘Mr X has attended this Party yesterday’ will only alienate the fans. If you are a celebrity or Personal brand, make sure you use it as a channel to directly connect to your fans. They will like it better that way!
It is important to drive to traffic to your Page so that you can catch the attention of Fans for a longer period and make that sale. Wall updates go to the Fan newsfeeds anyway, so there is no incentive to come to your Page.
Evaluate various Apps on offer and install a few on your Page to drive up the traffic. Apps improve the page browsing experience and make fans come back to you often.
Remember, Facebook took an unassailable lead over other networks primarily because of the addictive apps on offer. It works the same way for your Page too!
