Mistake #5: Promoting a lot of affiliate products instead of just a few. Once you start affiliate marketing, you realize how easy it is to share affiliate links. Instead of becoming an affiliate for a lot of different products and sharing them liberally, I recommend concentrating on just a few and sharing them intentionally. It doesn’t seem as spammy, plus you can be sure the products you do promote are closely aligned with your brand and message. Deep is better than wide.
Websites consisting mostly of affiliate links have previously held a negative reputation for underdelivering quality content. In 2005 there were active changes made by Google, where certain websites were labeled as "thin affiliates". Such websites were either removed from Google's index or were relocated within the results page (i.e., moved from the top-most results to a lower position). To avoid this categorization, affiliate marketer webmasters must create quality content on their websites that distinguishes their work from the work of spammers or banner farms, which only contain links leading to merchant sites.
