As search engines have become more prominent, some affiliate marketers have shifted from sending e-mail spam to creating automatically generated web pages that often contain product data feeds provided by merchants. The goal of such web pages is to manipulate the relevancy or prominence of resources indexed by a search engine, also known as spamdexing. Each page can be targeted to a different niche market through the use of specific keywords, with the result being a skewed form of search engine optimization.
Two-tier programs exist in the minority of affiliate programs; most are simply one-tier. Referral programs beyond two-tier resemble multi-level marketing (MLM) or network marketing but are different: Multi-level marketing (MLM) or network marketing associations tend to have more complex commission requirements/qualifications than standard affiliate programs.[citation needed]

Many voucher code web sites use a click-to-reveal format, which requires the web site user to click to reveal the voucher code. The action of clicking places the cookie on the website visitor's computer. In the United Kingdom, the IAB Affiliate Council under chair Matt Bailey announced regulations[46] that stated that "Affiliates must not use a mechanism whereby users are encouraged to click to interact with content where it is unclear or confusing what the outcome will be."
AWIN is probably best for experienced affiliates who can hit the ground running without a lot of guidance or feedback from the network. There is a $5 fee charged to apply to become an affiliate, but if you’re approved, the $5 will be added to your account. If your application is denied, however, you will lose the $5 fee. AWIN operates globally, but it is most heavily concentrated on British and EU merchants.
Cost per action/sale methods require that referred visitors do more than visit the advertiser's website before the affiliate receives a commission. The advertiser must convert that visitor first. It is in the best interest of the affiliate to send the most closely targeted traffic to the advertiser as possible to increase the chance of a conversion. The risk and loss are shared between the affiliate and the advertiser.
Products are now put in a category. The commission will be based on the category each product has been placed in whether or not the category is correct. For instance, I had a sale for a child riding toy tractor. Instead of it being in toys category which would have only earned me 3%, it was actually placed in lawn and garden category which I then actually earned 8% instead.
