Help with getting accepted with an ad company?

[Jake]

You can for the most part describe the subject matter of your site, perhaps throw in plans to review products.

The great majority of internet ad nenworks place ads on your site with no interview process, for most small operators you would apply through a self serve system that may rely on automated methods to accept or reject your site.
Google Adwords is the most popular ad network for small operators, after being approved, you place ad unit code on your pages which allows Google to dynamically insert ads matched to your pages, or the visitor/s history.
