You likely know better than to share the same post multiple times on Facebook. This principle is tossed out the window, though, for Facebook contests. Your contest will fail if you only post about it once and then wait for its conclusion. While making sure to provide great content throughout the day, also take the time to share the contest at least daily.
Please do me a favor by sharing this post with your friends. You can also let me know what you think of my post by leaving me a comment on my Facebook page and about other topics you would like me to cover.
