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 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."
That’s because the affiliate program works by setting a browser cookie when someone clicks on an affiliate link and tracks any purchases made at the destination before the cookie expires. After that, the affiliate program pays out a small commission. Thus, it’s possible to make a little money or even make a living off of affiliate marketing, but only if you can convince people to click on your links and buy your affiliate partner’s products.
Very useful info, and thanks for the heads-up about Etsy not allowing affiliate links on Pinterest! Have you ever tried advertising on Pinterest, i.e. paying Pinterest to promote your pins? I was wondering if that could be lucrative with affiliate marketing, where the margins are always lower than when you have your own product to sell. I’m also wondering if it would be lucrative to advertise on Google, Facebook and Youtube (found this guy who supposedly made a lot of money that way – https://moneytestimonials.com/crestani-free-webinar/ ). I’ll probably do my own experiments with this but if you have experience in this area I’d be very interested to hear about it!
