Hey Jan, glad it made you think. As you've found out it's not easy to rank #1 on Google especially when so few people will link to your product reviews. You need to tackle a specific niche with a focused target audience as a whole and build a community of like minded people around your site in order to make any significant income online sustainably and for the long term.
It's especially true now that the big media players are finally waking up to affiliate marketing (NYTime buying WireCutter and SweetHome) and BestReviews (which was already an epic product review site in it's self due to the fact they built their own 10,000 sq ft testing lab) being acquired by Tronc (owns the LA Times and half a dozen more publications).
With website builders, you get what you pay for. While they have plenty of free templates, more professional-looking websites will always cost more money. However, this investment could be worth it, especially as a website is one of the few startup costs for affiliate marketers. The social media profiles you develop are dependent on your niche and target market.
Web design is a very technical field that requires high literacy in many different kinds of software, including image editing and website architecture programs. A designer should be comfortable with computer “languages” like HTML and stay up to date on new technological developments. The designer is also an artist, so he or she should also have a firm grasp on aesthetics, visual continuity, and image composition.
According to HowStuffWorks, “Affiliate programs, also called associate programs, are arrangements in which an online merchant website pays affiliate websites a commission to send it traffic. These affiliate websites post links to the merchant site and are paid according to a particular agreement. This agreement is usually based on the number of people the affiliate sends to the merchant's site or the number of people they send who buy something or perform some other action.
In November 1994, CDNow launched its BuyWeb program. CDNow had the idea that music-oriented websites could review or list albums on their pages that their visitors might be interested in purchasing. These websites could also offer a link that would take visitors directly to CDNow to purchase the albums. The idea for remote purchasing originally arose from conversations with music label Geffen Records in the fall of 1994. The management at Geffen wanted to sell its artists' CD's directly from its website but did not want to implement this capability itself. Geffen asked CDNow if it could design a program where CDNow would handle the order fulfillment. Geffen realized that CDNow could link directly from the artist on its website to Geffen's website, bypassing the CDNow home page and going directly to an artist's music page.
