Facebook rules for contests held by businesses has, in the past, been confusing to some. Basically, though, Facebook did not allow a business or fan page to use comments or likes as a means to enter a contest.
That's all changed.
Facebook also updated its terms to discourage pages from tagging itself, or encouraging others to tag themselves, in images in which they do not actually appear. This in consistent with Facebook's intention to keep posts authentic.
Pages do still have the option of using an app to run a contest. As you might expect, there are pros and cons to each approach.
Some advantages to using a post:
- Cost (posts are free!)
Versus the advantages to using a third-party app:
- More flexibility
- Personalized look
- Easier tracking for larger contests
Things to consider:
- The size of your audience. Do you expect a number of responses that is manageable to count manually? Or do you need an app to do the tracking for you?
- The potential return on investment. Is it large enough to spend for a third-party app? Or do you need to more closely manage the costs?
