My blogoversary is a little more than a month away, and I want to start planning now. I've been staying with this blog (for the most part) for 2 years now. I've held contests and giveaways before but they were all publisher/author sponsored. For this big event it's all up to me and I need some advice.
What kind of giveaway should I have? For example, a summer theme, or romance.
I'm only in high school so I don't have much cash. How many winners? How many books do I give away?
Should I just have people leave comments for entries, or should I make them work a little?
These questions are directed at everyone, but especially those to book bloggers that have experience.
