Don’t exhaust all the information about the product with your link. Offer enough information to your readers so they know what the link is, but I don’t recommend giving too much detail on your own site for a two reasons. First, product information, like price, often changes. If you mention the price on your site and someone clicks over and finds a different price, it’s confusing. Second, many times, the product details and features are better explained by the makers of the product. It’s best to stick to your own experience on your site.
Cost per click was more common in the early days of affiliate marketing but has diminished in use over time due to click fraud issues very similar to the click fraud issues modern search engines are facing today. Contextual advertising programs are not considered in the statistic pertaining to the diminished use of cost per click, as it is uncertain if contextual advertising can be considered affiliate marketing.
Since July 2014 I read for the first time about affiliate marketing, I never heard of this way of working before. Until then, I have worked in MLM (multi-level-marketing). Which wasn't that suitable for me. MLM is a very aggressive way of marketing, and you do need to harass everyone around you to join. That's not quite me. Affiliate marketing works very different. You write reviews about products of a company, and when people decide to buy something after reading your review, you get a few percentage of the sale. That's more my line of work.
Websites consisting mostly of affiliate links have previously held a negative reputation for underdelivering quality content. In 2005 there were active changes made by Google, where certain websites were labeled as "thin affiliates". Such websites were either removed from Google's index or were relocated within the results page (i.e., moved from the top-most results to a lower position). To avoid this categorization, affiliate marketer webmasters must create quality content on their websites that distinguishes their work from the work of spammers or banner farms, which only contain links leading to merchant sites.
