Some merchants run their own (in-house) affiliate programs using dedicated software, while others use third-party intermediaries to track traffic or sales that are referred from affiliates. There are two different types of affiliate management methods used by merchants: standalone software or hosted services, typically called affiliate networks. Payouts to affiliates or publishers can be made by the networks on behalf of the merchant, by the network, consolidated across all merchants where the publisher has a relationship with and earned commissions or directly by the merchant itself.
Interests & Remarketing -This type of targeting means that you can target people based on what Google they might be interested in. The cool thing is that here you have a couple of options. You can choose “Affinity Audiences” — Target People in large numbers based on their long-term interests, “In-market Audiences” — Reach people that are actively searching and comparing products like yours, “Remarketing” — Target people that already had interaction with your website or app, “Customer email lists” — You can show ads in Gmail to people that have provided you with their Gmail email address.
Be sure to check what kind of customer support you can expect from your affiliate program once you have signed up. Do your research online and if possible, speak to other sellers using the program to get their thoughts. Can you speak to someone via phone or Skype or do you have to wait 72 hours for email responses? Be clear on this because trust me, you will need support at one point or another.
