I have a clothing accessory website. My objective is to sell "ad space" on my website. A banner at the top along with side and a banner at the footer. Website Demographics: My demographics are females ages 18 - 35 who make 20k-40k per month income. I am averaging about 500+ viewers per day, 80% of these viewers come from organic search engine results which I like. What is the most profitable and effective method to solicit ad space on my website? Any and all help is GREATLY appreciated!
