About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

Introduction: The importance of product tests in e-commerce

In the dynamic environment of e-commerce, especially on platforms such as Amazon, differentiation through quality is essential. Sellers are faced with the challenge of standing out from the crowd and gaining the trust of customers. A key strategy for this is the professional testing of products. This guide looks at the importance, process and long-term benefits of professional product testing specifically for Amazon sellers.

Why is product testing essential?

  1. Building trust: In a world where customer ratings and quality seals play a central role, the product confirmed by tests is synonymous with credibility and trust.
  2. Stand out from the competition: In a crowded market, an official seal of quality can help your product stand out from the rest.
  3. Increase in product quality: The testing process identifies weak points, which leads to an improvement in product quality. This results in higher customer satisfaction and reduces returns.
  4. Positive effects on the ranking: Products with high ratings and quality seals often receive a better ranking on Amazon, which leads to increased visibility and more sales opportunities.

Important product categories for tests

Almost every product category on Amazon can benefit from professional tests. These are particularly relevant for:

  1. Car & motorbike: This is all about reliability and safety. Products such as car batteries or motorbike helmets must meet the highest safety standards.
  2. Clothing: The quality of materials and workmanship is crucial. Durable and comfortable clothing stands out on the market.
  3. Garden: The durability and functionality of garden tools contribute to the aesthetics and maintenance of the garden.
  4. Baby & child: Safety and compatibility are the top priority here.
  5. DIY store: Tools and building materials must be convincing in terms of performance and quality in order to successfully support DIY projects.
  6. Living: Items for the home should be both stylish and functional.
  7. Sport & leisure: The functionality and quality of sports equipment are crucial for effective training.
  8. Household: Reliability and user-friendliness are in demand for household appliances.
  9. Outdoor: Robust and functional outdoor equipment is essential for adventures in the great outdoors.
  10. Pets: The safety and well-being of animals are the main focus of products for pets.
  11. Bathroom: The quality and functionality of bathroom products contribute to a pleasant bathroom.
  12. Technology: Performance and user-friendliness are decisive factors in the technology category.

The process of testing and obtaining a quality seal

  1. Selection of a testing company: The selection of a specialised and renowned testing company is crucial.
  2. Carrying out the tests: The products are subjected to a series of tests ranging from safety tests to performance tests.
  3. Receiving the seal of quality: After successful testing, a seal of quality is awarded, which can be presented on Amazon.
  4. Continuous monitoring: Regular retests guarantee that quality is maintained.

Long-term benefits of testing

  1. Build a loyal customer base: High-quality, tested products generate customer satisfaction and loyalty, which leads to repeat purchases and a loyal customer base. 2. positive customer reviews: Quality products often garner positive reviews, which in turn attracts new customers.
  2. Reduction in returns: A lower error rate means fewer returns and reduced costs.
  3. Strengthening the brand image: Consistently high quality standards promote the brand image and contribute to long-term success.
  4. Success on Amazon through professional product testing
  5. Choosing a professional testing company: Careful selection of the testing company is crucial. They should not only test the quality, but also award relevant certificates and seals.
  6. Utilising feedback for improvement: The results from the tests provide valuable feedback for improving the design, function and safety of the products.
  7. Marketing strategies with test seals: The emphasised presentation of test seals in the product description and marketing materials is an important sales factor that can increase the conversion rate.
  8. Long-term strategy and branding: Product testing should be seen as part of a comprehensive strategy that helps to strengthen the brand and customer loyalty.

Summary and conclusions

The professional testing of products and obtaining quality seals are key elements for success on Amazon. Not only do they promote customer trust and help to stand out from the competition, they also make a significant contribution to improving product quality. This results in higher customer satisfaction, lower return rates and ultimately a stronger market position. Product testing is therefore a crucial factor for Amazon sellers focussing on quality and customer satisfaction. It is a step towards long-term success and strengthens brand identity in a highly competitive market. In conclusion, the process of professionally testing products is an investment in the future of the brand and the company. It is not just about short-term gains, but about building a trustworthy, high-quality brand that is characterised by customer satisfaction and loyalty. In the world of e-commerce, where customer reviews and transparency play an increasingly important role, the importance of professional product testing will continue to grow in order to compete successfully in this dynamic market.
