I use Passion Fruit to run my ads. All ads are one size (250x100px). Each ad will be rotated daily and will run for 30 days. At any given time I have 20 spots available for purchase. Dearie Lovie is growing (1200-2000 views a month +) and I'd love for anyone interested to come along for the ride! The first week of the month all sponsors will be included in a 'sponsors post' in order to highlight your blog/business/etc further.
Disclaimer: This is a for profit blog and a full circle sponsorship blog. I will use half of the payment for my own personal use (that college thing does get kinda pricey) and the other half into sponsoring other blogs (gaining us both more exposure). Also, If you'd like more exposure and would like to create a large, XL, or custom ad spot do not hesitate to get in touch with me. We can definitely work something out!
