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.

Certified quality seals in e-commerce: building trust and confirming quality with Prüfgel

In today’s fast-paced e-commerce world, certified quality seals are a decisive factor for the success of online retailers. They serve as an anchor of trust for consumers and symbolise compliance with high quality standards. A prominent example of an institution that awards such quality seals is Prüfengel, a German institute for product testing. “At Prüfengel, we guarantee the highest standards when conducting our tests and awarding our quality seals, which are highly valued by consumers. Having your products certified by us not only provides objective confirmation of their quality, but also significantly increases customer confidence. Our seals stand for reliability and high quality, which leads to a noticeable increase in customer confidence in the tested products.” In this article, we will discuss the importance of certified quality seals for online retailers and their impact on the consumer market.

Building customer trust through quality seals

Certified quality seals are an essential tool for increasing customer confidence in online retailers. They show that a product has passed strict quality controls and has been tested by an independent, recognised institution. This gives customers a sense of security and reliability when buying online.

Differentiation in the online market

In a crowded online market, certified quality seals help products to stand out from the competition. They are a sign of superior quality and reliability and can have a positive influence on customers’ purchasing decisions. Products labelled with such seals stand out from other offers at first glance.

Improving product placement and visibility

Products with certified quality seals often enjoy preferential placement on e-commerce platforms. They receive higher visibility in search results and product lists, which can lead to an increase in sales figures. Online retailers therefore benefit from an improved market presence.

Minimisation of customer complaints and returns

Quality seals minimise the risk of customer complaints and returns as they guarantee compliance with certain quality standards. Customers who buy products with such seals know that they can rely on the quality and safety of the product.

Feedback for continuous improvement

The processes that lead to the award of a certified quality seal provide valuable feedback for online retailers. They can use this feedback to continuously improve their products and adapt them to the needs of their customers.

Long-term benefits and customer loyalty

Certified quality seals contribute to long-term customer loyalty. Customers who know that products are regularly tested and certified often develop greater loyalty to the brand. This leads to repeat purchases and recommendations, which ensures the long-term success of the business.

The role of quality seals in branding

Branding is an important aspect of business for online retailers. Quality seals make a significant contribution to strengthening the image of an online shop as a trustworthy and reliable provider. They are an important part of the brand identity and help to stand out positively from the competition.

Adaptation to changing market conditions

Being labelled with quality seals shows that an online retailer is willing to invest in quality assurance and constantly adapt products to the latest safety standards and customer requirements. In a rapidly changing e-commerce landscape, these seals help to respond quickly to new trends and consumer needs, which is essential for maintaining competitiveness and relevance.

Conclusion: Certified quality seals as a strategic tool for online success

In conclusion, it can be said that certified quality seals represent far more than just a formal confirmation of product quality for online retailers. They are a crucial tool for creating trust, improving brand strength and increasing competitiveness. In an online world where customer reviews and perceived quality are decisive factors for purchasing, quality seals offer a significant advantage.

Increasing competitiveness

In a market that is constantly producing new suppliers and products, it is crucial for online retailers to stand out through proven quality and security. Certified quality seals are a clear indicator of a company’s commitment to quality, which helps to differentiate and increase competitiveness.

Risk management and compliance

Cooperation with certification bodies for quality seals is also an essential part of risk management for online retailers. It helps to minimise product risks and ensure compliance with legal requirements.

Summary: The strategic importance of certified quality seals

To summarise, certified quality seals are a key element for 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, certified quality seals are crucial to being a trustworthy provider 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.
