I started to feel that Giveaways no longer work for gaining attention. The only way out is to be a star yourself or do things that are really viral (stupid).
Recently, I've run two giveaways with two micro pages I'm involved, respectively.
Giveaway 1 is a traditional kind of giveaway. People need to follow our page, like the post and tag friends.
Giveaway 2 is much simpler. Just follow the page and answer an extremely simple question. You don't even need to tag friends.
Guess what? Both were so dead. I feel like I have to beg people to come get the free stuff (shipping is, of course, free), but still, no one wants to bother.
