Websites and services based on Web 2.0 concepts—blogging and interactive online communities, for example—have impacted the affiliate marketing world as well. These platforms allow improved communication between merchants and affiliates. Web 2.0 platforms have also opened affiliate marketing channels to personal bloggers, writers, and independent website owners. Contextual ads allow publishers with lower levels of web traffic to place affiliate ads on websites.
Another difference is that with affiliate marketing business, an affiliate can sell different products all at the same time. His selling potential is limitless. Even if the products are not related to one another, he can still do affiliate marketing. He only needs to create a separate website to market different products. Unlike with offline middleman marketing, a middleman must only sell related products to maintain his credibility, for who would take a salesman seriously who sells cars and baby products at the same time?
