Thinking of doing a free giveaway on my Instagram account to increase engagement. I am in the weight loss niche but cant decide what i should give to the winner. It will be a tag a friend/like/follow type competition. I'm hoping to increase the engagement on my page that will result in opt-ins on my list.
What sort of things could I give away to the winner? Any suggestions and how I should run this? Is it a good idea?
