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.

Product testing services for Amazon sellers: a must for quality and customer satisfaction

In the world of online retail, especially on platforms such as Amazon, the landscape for sellers has changed drastically. Customers now expect more than ever before – not only in terms of product variety and price, but also in terms of quality and reliability. Product testing services offer an essential solution for Amazon sellers to meet these demands and successfully position their products. In this article, we explore why product testing services are essential for Amazon sellers and how they can ensure long-term success on the platform.

Building trust through product tests

Trust is the currency of online retail, and product review services are an effective means of building this trust. Through independent and objective reviews, they signal to customers that a product meets high quality standards. For Amazon sellers, investing in such tests means that they are seriously concerned about the quality of their products and are prepared to have them confirmed by external experts.

Differentiation in a highly competitive market

Amazon is known for its intense competition. Products that are tested and recommended by product testing services stand out from the competition. A positive test result can be a decisive factor that attracts the attention of customers and prompts them to decide in favour of a particular product.

Increase in product placement and visibility

Positive reviews from review services can significantly improve the visibility of a product on Amazon. Products with high ratings are often ranked higher in search results, leading to increased visibility and potentially more sales.

Minimisation of returns and customer complaints

By using product testing services, Amazon sellers can reduce the risk of returns and customer complaints. High-quality, tested products are more likely to meet customer expectations, resulting in higher satisfaction and fewer returns.

Feedback and continuous improvement

Product testing services not only provide a snapshot of product quality, but also valuable feedback for the further development of products. This feedback helps sellers to continuously improve their products and adapt them to the needs of their customers.

Long-term benefits of product testing services

The long-term benefits of using product testing services are manifold. They range from increasing customer trust and satisfaction to improving brand perception and customer loyalty. Satisfied customers are more likely to leave positive reviews and recommend the product to others, which leads to a stronger market position.

The role of product tests in customer loyalty

Customer satisfaction is a decisive factor for success on Amazon. By ensuring that products meet the high standards of the product tests, sellers can build a loyal customer base. Satisfied customers are more likely to buy again and make positive recommendations.

Adaptation to changing consumer trends

Product testing services enable sellers to react quickly to changing consumer trends. They provide up-to-date information on which aspects of product quality are most important to customers and help sellers to adapt their products accordingly.

Conclusion: Product testing services as an indispensable tool for Amazon sellers

To summarise, it can be said that product testing services are an indispensable tool for Amazon sellers. They are not only a means of quality assurance, but also an important part of the marketing strategy. Using these services can make the difference between a product that gets lost in the crowd and one that stands out for its quality and trustworthiness.

Risk management and compliance

Compliance with legal regulations and industry standards is essential for Amazon sellers. Product testing services not only check products for quality, but also ensure that they fulfil all relevant safety and compliance standards. This minimises the risk of legal problems and strengthens customer confidence in the brand.

Increasing competitiveness

In an increasingly saturated market, it is important for Amazon sellers to have a competitive advantage. Products that are recommended by independent review services enjoy increased credibility, which leads to a better competitive position. This can be crucial to succeed in a highly competitive environment.

Summary: The strategic importance of product testing services

In conclusion, product testing services are of great strategic importance for Amazon sellers. Not only do they provide a way to ensure product quality and safety, but they also increase brand strength and customer confidence. By investing in such services, sellers can market their products more effectively, stand out from the competition and ensure long-term success on Amazon. In a world where customers are becoming increasingly demanding and informed, product testing services are a crucial tool to meet these demands and compete as a trusted seller in the online world.
