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.

In the dynamic world of online retail, product testing organisations play a central role, especially for Amazon sellers. These organisations provide objective and independent verification of product quality and safety, which is critical to the credibility and success of online sellers. This article discusses how testing organisations can improve the performance and reputation of Amazon sellers.

Building customer confidence through test institutes

  • Promoting trust: Cooperation with test institutes signals to customers that the products have been thoroughly tested for quality and safety.
  • Increased credibility: Independently conducted tests increase the credibility of the products and the seller.

Differentiation in the Amazon market

  • Highlighting the products: Products that have been tested and approved by test institutes stand out from the competition.
  • Competitive advantage: The quality confirmed by tests can lead to a decisive competitive advantage on Amazon.

Improve product placement and increase sales

  • Increased visibility: Products with positive test results are often prioritised on Amazon.
  • Increased sales: Greater visibility generally leads to an increase in sales figures.

Reduction in returns and customer complaints

  • Quality assurance: The quality confirmed by testing institutes leads to a reduction in customer complaints and returns.
  • Customer satisfaction: Higher satisfaction with the products reduces the likelihood of returns.

Feedback and product improvement

  • Valuable insights: Test institutes provide valuable feedback that can be used to improve products.
  • Adaptation to customer needs: This information helps Amazon sellers to continuously optimise their products and better adapt them to customer needs.

Long-term benefits and customer loyalty

  • Build brand loyalty: Investing in quality-tested products promotes long-term customer relationships.
  • Repeat purchases: Satisfied customers are more likely to buy from the same seller again.

Importance of test institutes for branding

  • Strengthening the brand: Test institutes make a significant contribution to strengthening the brand and establishing a positive image.
  • Brand differentiation: In a world dominated by customer reviews, positive test results help you stand out from the competition.

Adaptability to market changes and consumer trends

  • Follow market developments: Test institutes enable Amazon sellers to adapt quickly to market changes and new consumer trends.
  • Fulfilment of current requirements: They ensure that the products meet the latest quality and safety standards.

Conclusion: Test institutes as a strategic advantage for Amazon sellers

Finally, test institutes play a decisive role in the success of Amazon sellers. Not only do they provide confirmation of product quality, but they are also an effective tool for increasing customer confidence, brand loyalty and competitiveness. In a world where consumers are increasingly looking for high-quality and safe products, test institutes are a key element in achieving long-term success in e-commerce. They enable Amazon sellers to position themselves as trustworthy and quality-conscious suppliers and build a strong relationship with their customers.

Increasing competitiveness

Amazon sellers can increase their competitiveness by cooperating with test institutes. Products that have passed independent quality and safety tests give customers a higher level of trust and security. This leads to increased customer satisfaction and loyalty, which in turn increases the chances of repeat purchases and positive reviews.

Risk management and compliance

Test institutes also play an important role in risk management. They help to minimise the risk of product defects and ensure compliance with legal regulations and safety standards. This is particularly important for products that are subject to specific safety regulations.

Summary: The strategic importance of test institutes

To summarise, test institutes for goods are a key element for the success of Amazon sellers. Not only do they provide confirmation of product quality, but they are also an effective tool for brand reinforcement and customer loyalty. In a world where consumers are increasingly looking for high quality and safe products, independent product testing is crucial to ensure long-term success in e-commerce. Test organisations enable Amazon sellers to gain a strong position in the market, build trust with customers and build lasting relationships with their customers.
