Well, it depends on many factors but all in all, if you find a way to lower the costs and make sure that you won’t exceed Instagram limits, then yes! It’s worth it and will result in more leads, sales conversion, and engaged followers. Plus, studies show that accounts that run regular giveaways get 70% more followers than those that don’t. Further, 91% of posts with over 1K comments are giveaway posts. While users will unfollow some of the participants after the reward is announced, there tends to be a 75% retention rate of followers which is well worth the investment.
Note: Make sure that your giveaway rules are in line with IG's promotion guidelines and terms of use.
