File-Sharing: Web sites that host directories of music, movies, games and other software. Users upload content to file-hosting sites and then post descriptions of the material and their download links on directory sites. Uploaders are paid by the file-hosting sites based on the number of times their files are downloaded. The file-hosting sites sell premium download access to the files to the general public. The websites that host the directory services sell advertising and do not host the files themselves.
Considerando che il carrello medio dell’acquisto sul sito di ecommerce sia € 300, il margine medio dell’advertiser il 30% (net profit € 90); la commissione sarà una percentuale (tendenzialmente un 5 – 10%) del net profit medio. Un CPA fisso, se i prodotti venduti generano una revenue unitaria media abbastanza o completamente uniforme (calcolato sempre su un 5/10% del net profit). Criticità : Difficile generare grandi volumi se il cliente non è un grande player con già una big reputation sul mercato.
Si adotta quando l’obiettivo del cliente è generare un contatto da trasformare in un secondo momento in un cliente; il CPL è calcolato dal cliente in base al lifetime value dell’utente, al valore medio del utente convertito e al proprio costo interno di conversione (CRM, call center etc.). Il modello di share della commissione fra publisher e network non cambia (30% / 70%). Criticità: modello molto esposto alle fake conversion.
The General Data Protection Regulation (GDPR), which took effect on May 25, 2018, is a set of regulations governing the use of personal data across the EU. This is forcing some affiliates to obtain user data through opt-in consent (updated privacy policies and cookie notices), even if they are not located in the European Union. This new regulation should also remind you to follow FTC guidelines and clearly disclose that you receive affiliate commissions from your recommendations. 
Individual sellers and companies offering products or services have to deal with their consumers and ensure they are satisfied with what they have purchased. Thanks to the affiliate marketing structure, you’ll never have to be concerned with customer support or customer satisfaction. The entire job of the affiliate marketer is to link the seller with the consumer. The seller deals with any consumer complaints after you receive your commission from the sale.

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.[14]
