Contests and Giveaways: Short Post Asking for Advice

I started entering contests and giveaways this month. I’ve been very privileged to win many novels, as you can see by my growing reading list. I wanna learn how to do giveaways also. Please, if you have any advice, programs, methods, tutorials, etc. you’ve found helpful when doing giveaways, let me know. I’d love to try a contest giveaway this weekend.
