1. Statistics About Your Site. Provide the number of unique visitors and page views that your site gets per month. Other metrics you might include are the pages per visitor ratio, the average time spent on the website, the percentage of organic traffic, geographical breakdown of your traffic and so on.
2. Information About Your Audience.
Advertisers want to know what kind of people visit your see, to determine whether or not your audience is a good match for their products and services.
3. Description Of The Advertising Options.
The third essential element is a description of the advertising options you have on your website. Make sure to list the banner sizes and placements, the max number of sponsors for each placement, and other specific requirements you might have (e.g., file size, whether animated GIFs are allowed and so on).
