About
Today’s consumers are confronted with a huge selection of product choices and an even larger collection of information on these products. Best Product Spy radically streamlines the research process by daily presenting the top 5 products in major consumer categories. Our rankings are based on up-to-the-hour sales data from leading online retailers.
Why use sales rank to rate products?
- In the age of Internet and mobile social media, word of a disappointing product gets out almost instantly. When many consumers buy a given product and the buzz remains positive, that product has survived the sometimes brutal social media litmus test.
- A large user base strengthens a manufacturer’s support of a product. To maintain positive branding and ensure additional purchases of related products, the manufacturer has a built-in incentive to provide a positive customer experience.
- A large user base strengthens a manufacturer’s long-term commitment to a product. The consumer can be confident that years down the road support and accessories will still be available.
Happy shopping and keep it simple!
