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.

The relevance of certified product tests in e-commerce

In the dynamic world of online retail, certified product tests are a decisive factor for success for Amazon sellers. These tests provide an independent and reliable assessment of product quality, which is important for customers when buying online. In this article, we look at how certified product testing can help Amazon sellers build trust, stand out from the competition and ensure long-term business success.

Building customer trust through certification

  • Confirmation of quality: Certified product tests provide independent confirmation of quality, which creates trust among customers.
  • Proof of safety: They demonstrate that the products are safe to use, which is a decisive factor in the purchasing decision.
  • Transparency and credibility: By presenting certified test results, Amazon sellers demonstrate transparency and strengthen their credibility.

Differentiation in the Amazon market

Certified product tests enable Amazon sellers to set their products apart from the competition. Products that pass these tests are perceived by customers as higher quality and more trustworthy. This is a decisive advantage on a marketplace like Amazon, where the variety of products is huge and customers are looking for reliable purchase criteria.

Increase in product placement and sales figures

  • Higher visibility: Products with positive test results often enjoy preferential placement on the Amazon platform.
  • Sales promotion: This can lead to an increase in sales as customers are more likely to buy products that are certified as high quality.

Reduction in customer complaints and returns

Products that pass certified product tests tend to meet or exceed customer expectations. This leads to a lower rate of returns and customer complaints, which in turn increases customer satisfaction and reduces the costs associated with returns.

Valuable feedback for continuous product improvements

  • Potential for improvement: The results of certified product tests provide Amazon sellers with important information about the strengths and weaknesses of their products.
  • Product optimisation: These insights are crucial for continuously improving products and adapting them to customers’ needs.

Long-term benefits and customer loyalty

  • Brand loyalty: Investment in certified product testing demonstrates Amazon sellers’ commitment to high quality and customer satisfaction.
  • Repeat purchases: This promotes long-term customer loyalty and leads to repeat purchases and recommendations.

Importance of certified tests for branding

Certified product tests make a significant contribution to brand building. They help Amazon sellers to establish themselves as trustworthy and quality-conscious brands. In a world where customer reviews and product quality play a central role, such tests are crucial to stand out from the competition.

Adaptability to market changes and consumer trends

  • Market requirements: Certified product tests enable Amazon sellers to react quickly to market changes and new consumer trends.
  • Current standards: They ensure that the products comply with current quality and safety standards.

Conclusion: Certified product tests as the key to success for Amazon sellers

In conclusion, certified product tests are an indispensable tool for Amazon sellers to assert themselves on the highly competitive online marketplace. They are not only a means of quality assurance, but also a crucial tool for increasing customer confidence, improving competitiveness and fostering brand loyalty. In a world where consumers increasingly value verified product quality, certified tests offer a significant advantage.

Increasing competitiveness

By providing products that have passed independent quality tests, Amazon sellers can strengthen their competitive position. These tested products give customers a sense of security and reliability, increase customer satisfaction and loyalty and thus increase the chances of repeat purchases and positive reviews.

Risk management and compliance

Certified product tests are also an important part of risk management for Amazon shops. They minimise the risk of product defects and ensure that products comply with legal regulations and safety standards. This is particularly important for products that fall under special safety regulations.

Summary: The strategic importance of certified product tests

To summarise, certified product tests play a key role in the success of Amazon sellers. Not only do they help to ensure 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, certified product tests are crucial to achieving long-term success in e-commerce. They enable Amazon sellers to position themselves as trustworthy and quality-orientated suppliers and build a strong relationship with their customers.
