Is there anywhere to get complete or recent articles/conversations regarding online promotions specifically for camps? A comparative on search engine advertisement, traditional marketing campaigns and online camp search directories? Need to pick ways to maximize my exposure with a very small budget.

Check out http://www.campmarketingnews.com. It's a free "how to market your summer camp" blog.

I am also agree with all of you about the online marketing but I think we also should do offline marketing for getting the customers. Create business cards with coupon codes on them, Print posters with QR codes, Mail out postcards to a target mailing list, Join a club that promotes networking. May it's prove useful for some one.
