Although online marketing creates many opportunities for businesses to grow their presence via the Internet and build their audiences, there are also inherent challenges with these methods of marketing. First, the marketing can become impersonal, due to the virtual nature of message and content delivery to a desired audience. Marketers must inform their strategy for online marketing with a strong understanding of their customer’s needs and preferences. Techniques like surveys, user testing, and in-person conversations can be used for this purpose.
Always make affiliate links nofollow. Google’s goal is to provide its users with the best possible search results to their search queries.

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. 

How much will you make? I think my best month with Google AdSense was almost $5,000 over the last ten years.

For me, it also got me even more excited because I knew there were other ways to monetize.
