Some advertisers offer multi-tier programs that distribute commission into a hierarchical referral network of sign-ups and sub-partners. In practical terms, publisher "A" signs up to the program with an advertiser and gets rewarded for the agreed activity conducted by a referred visitor. If publisher "A" attracts publishers "B" and "C" to sign up for the same program using his sign-up code, all future activities performed by publishers "B" and "C" will result in additional commission (at a lower rate) for publisher "A".

Shifting the focus to the time span, we may need to measure some "Interim Metrics", which give us some insight during the journey itself, as well as we need to measure some "Final Metrics" at the end of the journey to inform use if the overall initiative was successful or not. As an example, most of social media metrics and indicators such as likes, shares and engagement comments may be classified as interim metrics while the final increase/decrease in sales volume is clearly from the final category.

Does affiliate marketing still work, as Google doesn’t allow affiliate links or the promotion of affiliate links. So I can’t create an ad directing to an affiliate link, and I can’t create a landing page (and promoting the landing page), with a single purpose of sending users to the affiliate link. Except RTB platforms and Blog based SEO that takes years to build, how can I do affiliate marketing ?
Option 1: Payment by Direct Deposit. We will directly deposit the fees you earn into the bank account you designate once you have provided us with the name of your bank, the account number, the name of the primary account holder as it appears on the account, and other requested identifying information (such as the ABA, IBAN or BIC number, if applicable). If you have chosen payment by direct deposit and you do not provide this information, or it is not valid (for example, the account has been closed or changed), or the payment is otherwise rejected by your bank, you may instead receive payment by check which will be subject to the processing fees described below until you provide valid account information. If you select this option, we reserve the right to hold fees until the total amount due to you reaches the minimum stated in the Payment Minimum Chart.
Sellers are responsible for claims they make about their products and services. Third parties - such as advertising agencies or website designers and catalog marketers - also may be liable for making or disseminating deceptive representations if they participate in the preparation or distribution of the advertising, or know about the deceptive claims.
Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.[citation needed]
