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 importance of authorisation seals in online retail

Approval seals play a crucial role in the success of Amazon sellers in modern e-commerce. These seals serve as proof that products fulfil certain quality and safety standards and are therefore a key element in gaining the trust of customers. In this article, we look at the importance of certification seals for Amazon sellers and how they can help increase brand presence and sales.

Building customer confidence through approval seals

  • Quality confirmation: Approval seals signal to customers that a product meets tested quality standards.
  • Promoting trust: You increase the credibility of the products and the seller.
  • Purchase decision: Approval seals make the decision easier for customers by providing reliable confirmation of quality.

Market differentiation through approval seals

  • Product profiling: Approval seals help Amazon sellers to differentiate their products from the competition.
  • Competitive advantage: They offer a clear competitive advantage, as products with a seal of approval are perceived as being of higher quality.

Increase visibility and sales figures

  • Increased product presence: Products with an approval seal often enjoy preferential placement on Amazon.
  • Sales growth: This increased visibility can lead to an increase in sales figures.

Reduction in customer complaints and returns

  • Satisfaction guarantee: Approval seals help to ensure that products fulfil or exceed customer expectations.
  • Reduction in the return rate: This leads to a reduction in customer complaints and returns.

Valuable feedback for product improvements

  • Targeted improvements: Amazon sellers receive valuable feedback on product quality through approval seals.
  • Product optimisation: This information is crucial for adapting products to customers’ needs.

Long-term benefits and customer loyalty

  • Building a loyal customer base: Providing products with a seal of approval demonstrates a commitment to high quality and customer satisfaction.
  • Repeat purchases: Satisfied customers tend to buy from the same seller again.

Strengthening the brand with a seal of approval

  • Brand image: Approval seals make a significant contribution to strengthening the brand image and help to establish the company as a quality-conscious provider.
  • Standing out from the competition: In a world dominated by customer reviews, seals of approval help you to stand out from the competition.

Responding to market changes and consumer trends

  • Market adaptation: Approval seals enable Amazon sellers to react 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: Seal of approval as a strategic advantage

In conclusion, approval seals are a decisive factor for the success of Amazon sellers. Not only do they provide confirmation of product quality, but they are also an effective tool for increasing customer trust and brand loyalty. In a world where customers are increasingly looking for high quality and trustworthy products, approval seals offer a significant advantage. They enable Amazon sellers to position themselves as reliable and quality-conscious suppliers, which in turn leads to increased customer satisfaction, repeat purchases and stronger customer loyalty.

Increasing competitiveness

The use of approval seals can significantly increase the competitiveness of Amazon sellers. These seals show customers that the products have passed stringent quality and safety tests, which leads to increased customer satisfaction and loyalty and increases the chances of repeat purchases and positive reviews.

Risk management and compliance

Approval seals are also an important part of risk management for Amazon shops. 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 fall under special safety regulations.

Summary: The strategic importance of certification seals

In summary, approval seals play a central role in the success of Amazon sellers. They provide confirmation of product quality and are an effective tool for brand reinforcement and customer loyalty. In a world where consumers are increasingly quality-conscious shoppers, seals of approval are crucial to ensure long-term success in e-commerce. They enable Amazon sellers to gain a strong position in the market and build a lasting relationship with their customers.
