Many consumers have reservations about online behavioral targeting. By tracking users' online activities, advertisers are able to understand consumers quite well. Advertisers often use technology, such as web bugs and respawning cookies, to maximizing their abilities to track consumers.[60]:60[95] According to a 2011 survey conducted by Harris Interactive, over half of Internet users had a negative impression of online behavioral advertising, and forty percent feared that their personally-identifiable information had been shared with advertisers without their consent.[96][97] Consumers can be especially troubled by advertisers targeting them based on sensitive information, such as financial or health status.[95] Furthermore, some advertisers attach the MAC address of users' devices to their 'demographic profiles' so they can be retargeted (regardless of the accuracy of the profile) even if the user clears their cookies and browsing history.[citation needed]
Professional gold affiliates take percentage programs and build a system around it, where they will create either advertising campaigns, a website specific to the offer, or a combination of the two. They then tweak the adverts and their side of the offer until they are making substantially more than their advertising or SEO costs – and then they scale.
Too many newbies make this mistake. They think they can avoid ALL online business start-up time and expenses by joining an affiliate program and using the free site they get as their main site. It's a mistake. The best affiliates in EVERY program have their own website where they bring ALL their traffic first. From a "home base" like this you are free to make personal recommendations, promote a variety of programs and earn income other ways such as advertising or selling your own products and services. Growing your own site is a major key to growing serious long-term affiliate income.
The publisher ad server then communicates with a supply-side platform server. The publisher is offering ad space for sale, so they are considered the supplier. The supply side platform also receives the user's identifying information, which it sends to a data management platform. At the data management platform, the user's identifying information is used to look up demographic information, previous purchases, and other information of interest to advertisers.

The network is, again, contested by some as to whether it’s truly a part of the affiliate marketing conglomerate. But for good measure, we’ll discuss it. The network is essentially the middle man used to manage this exchange. The network helps accomplish such tasks as payment processing, tracking technology, reporting solutions, and can serve as a repository of available affiliates.
Murphy has grown the affiliate channel to represent 11 percent of her overall revenue. She hopes that she will be able to grow that number to 20 percent. What she likes most about the affiliate channel is that it is performance based — instead of paying for ad placements and hoping that they work, she pays a 12 percent commission on actual sales generated. The program tracks sales based on a 365-day cookie, which means that affiliates earn commissions on repeat purchases that occur within one year of the initial referral.
In February 2000, Amazon announced that it had been granted a patent[18] on components of an affiliate program. The patent application was submitted in June 1997, which predates most affiliate programs, but not PC Flowers & Gifts.com (October 1994), AutoWeb.com (October 1995), Kbkids.com/BrainPlay.com (January 1996), EPage (April 1996), and several others.[13]
