You can buy almost anything on Amazon, which means you can earn a commission off of almost any product if you’re an Amazon Affiliate. After signing up for the affiliate program you can give readers of your blog, Twitter feed, etc. special links to Amazon products. If they click on the link and buy that product or anything else on the site during that visit, you receive a small commission that can really add up over time. Pickmyshaver. com. which reviews shaving devices with links to the Amazon listings, is a prime example of a successful affiliate website. It sold for over $60,000 to Flippa just eight months after it debuted. Your chances of reaping similar rewards are reasonably good if your reviews attract a lot of attention, so write them well and and convincingly so they’ll read the review and then buy the product.
