Starting today, people have the ability to tag Pages in their photos on Facebook in the same way they can tag their friends. Photo tagging for Facebook Pages enables people to share richer stories with friends about the things they interact with in the real-world, such as businesses, brands, celebrities, and musicians.
A Page can be tagged anywhere that someone can view a photo in the photo viewer. These photos will appear on the Photos tab on the Page, and not on the Wall. In addition, a Page can be tagged by anyone on Facebook, not just people who have Liked your Page.
But there are lots of potential problems, and a moderation nightmare
What Facebook doesn't seem to have considered is that this whole commercial feature relies on the goodwill of the Facebook community to do the linking work, almost Wikipedia-style. Sure, in Facebook's ideal world, every Coke can in every photo will get "tagged" to Coca-Cola's page.
But isn't it likely that sooner or later users will find the tagging feature a fun little game, where Coke cans are tagged to Pepsi's page?
A far larger corporate relations problem for Facebook will be when users tag, say, photos of retailer Target to, say, Vote Yes on Prop 8's page. Or, how about PETA tagging images of slaughtered chickens to KFC's page or any one of a number of brands to the Boycott Scott Walker Contributors page?
