I’m not a huge fan of facebook fan pages for job boards. I’ve used it for my flagship site for years but it never really gained many followers. But lately its picked up a few fans and I think I know why.
I have it setup to re-post certain jobs but I recently began an effort to post more relevant content for fans as well. So I add an article or two a day about companies in the news in Connecticut that talk about growing or hiring. That seems to bring more relevance to the page itself. The other thing I noticed is that its better to add the content in the eveving which is when most people logon to facebook itself.
Timing is everything. The majority of facebook visitors come to the site during the day and evening between 5-8pm. So I think the more content you post later in the day is more likely to be seen.
