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 agencies as partners for quality and trust

Product testing agencies are becoming increasingly important in the dynamic environment of online retail. They serve as independent bodies that objectively assess the quality and safety of products. One such agency, Prüfengel, a renowned German institute for product testing, is a prime example of quality assurance in e-commerce. “At Prüfengel, we guarantee you the highest quality in tests and test seals, which are held in high regard by consumers. By having your product tested by us, you not only ensure objective confirmation of quality, but also increase consumer confidence in your products. Our test seals symbolise reliability and quality, which noticeably increases customer confidence in your tested products.” In this article, we look at the importance of product testing agencies such as Prüfengel for online retailers and the benefits they offer.

Building customer confidence through independent product tests

Customer trust is a key factor for success in online retail. Product testing agencies play a decisive role in this by providing an objective assessment of product quality. This independence is an important indicator for customers, offering them security when shopping online.

Differentiation from the competition through quality seals

In a market where customers can choose from a wide range of products, differentiation through quality is a decisive factor. Product testing agencies such as Prüfengel award a seal of quality to products that successfully pass their tests. Such seals are a sign of the highest quality for customers and can significantly influence their decision in favour of a product.

Increase in product placement and visibility

Products that have been awarded a seal of quality from a renowned test agency often enjoy preferential placement on online platforms. This leads to increased visibility of the products, which in turn increases the likelihood of purchases.

Reduction in customer complaints and returns

By ensuring that products pass the rigorous tests of an agency such as Prüfengel, online retailers can minimise the risk of customer complaints and returns. This contributes to customer satisfaction and protects the company’s reputation.

Feedback for continuous product improvements

The detailed test reports from agencies provide valuable feedback that online retailers can use to continuously improve their products. This helps to maintain product quality and adapt to the changing needs of customers.

Long-term benefits and brand strengthening

Working with a product testing agency helps to strengthen the brand in the long term. Products that are regularly tested and certified build a strong brand that stands for quality and reliability. This promotes customer loyalty and supports long-term business success.

The role of product testing agencies in brand building

Product testing agencies make a significant contribution to brand building. They support online retailers in building an image that stands for quality, safety and trustworthiness. In a world where customers increasingly value transparency and authenticity, such agencies are indispensable.

Adaptation to changing market conditions

Product testing agencies help online retailers to adapt quickly to changing market conditions. They provide up-to-date information on quality standards and consumer expectations, which is crucial for the development and customisation of products.

Conclusion: Product testing agencies as indispensable partners for online retailers

In conclusion, product testing agencies such as Prüfengel play a central role in online retail. They are not only a means of quality assurance, but also a decisive factor in building trust, differentiating products from the competition and strengthening brands in the long term. Through their independent tests and the awarding of quality seals, they help online retailers to assert themselves in a highly competitive market and gain the trust of consumers.

Increasing competitiveness

Product testing agencies increase the competitiveness of online retailers by ensuring that their products fulfil the highest quality standards. This is particularly important at a time when customers are becoming increasingly demanding and informed.

Risk management and compliance

Collaboration with product testing agencies is also an essential part of risk management. It helps online retailers to minimise product risks and ensure compliance with legal requirements.

Summary: The strategic importance of product testing agencies

To summarise, product testing agencies are a key element in the success of online retailers. Not only do they provide a way to ensure product quality, but they are also a powerful tool in marketing and customer communication. In a world where consumer expectations are constantly rising, product testing agencies are crucial to being a trusted supplier and achieving long-term success in e-commerce. Investing in such services is therefore an investment in the future of the company and helps to build a strong and trustworthy brand.
