The Publisher is the website who advertises a product or service and earns a commission when their visitor goes on to the site and makes a purchase. There are so many different types of affiliates including influencers, bloggers, or loyalty websites and more non-traditional affiliates too, including paid search, on-site tech solutions and remarketing to name a few.
If part of your affiliate strategy is to allow brand rights to select PPC affiliates (either as direct to merchant PPC or as a complementary PPC campaign through a landing page) you will have to consider the commission levels that are paid to these affiliates. If the commission paid on the sale does not cover the affiliates click costs with additional profit margin, then a PPC campaign would not be a viable offer for the affiliate.
Two other practical limitations can be seen in the case of digital marketing. One,digital marketing is useful for specific categories of products,meaning only consumer goods can be propagated through digital channels.Industrial goods and pharmaceutical products can not be marketed through digital channels. Secondly, digital marketing disseminates only the information to the prospects most of whom do not have the purchasing authority/power. And hence the reflection of digital marketing into real sales volume is skeptical.
In November 1994, CDNow launched its BuyWeb program. CDNow had the idea that music-oriented websites could review or list albums on their pages that their visitors might be interested in purchasing. These websites could also offer a link that would take visitors directly to CDNow to purchase the albums. The idea for remote purchasing originally arose from conversations with music label Geffen Records in the fall of 1994. The management at Geffen wanted to sell its artists' CD's directly from its website but did not want to implement this capability itself. Geffen asked CDNow if it could design a program where CDNow would handle the order fulfillment. Geffen realized that CDNow could link directly from the artist on its website to Geffen's website, bypassing the CDNow home page and going directly to an artist's music page.
