If I have a blog that is getting 100,000 page views a month that means that I’m probably getting at least 50,000 people to the site (most blogs will do between 1.2 to 1.4 pages per session). That means I have to try and get some small percentage of those people to buy something from me if I really want to do well. If I can’t get them to buy something then (in some cases) I have ads running on the site that will make me money anyways.
The License will immediately and automatically terminate if at any time you do not timely comply with any obligation under the Program Documents (as defined in the Fee Schedule), or otherwise upon termination of this Agreement. In addition, we may terminate the License in whole or in part upon written notice to you. You will promptly stop using the Program Content (including PA API and Data Feeds) and promptly remove from your Site and delete or otherwise destroy all of the Program Content and Amazon Marks with respect to which the License is terminated or as we may otherwise request from time to time.
The topic you choose must have enough depth that you can create a lot of content for it. This is important for building an authoritative site, for search engine optimization, and most importantly, for the end user. If you don't have enough content about a topic, you're not going to be taken very seriously as an authority on the topic and it's unlikely you can convince someone to make a purchase from you.
