What makes a website or online shop successful?

Digital Customer Experience: Usability as a success factor
Can users orient themselves on your website or are they annoyed by the navigation system and switch to a competitor’s instead? Does your website communicate your brand or is the page confusing your target group? All details such as headlines, colours, and text, regardless of their size, can be decisive to the success of your website. How is the usability of your web page? Is it effective, efficient and able to satisfy users? In 2003, Jacob Nielsen, a web usability expert, calculated an ROI (return on investment) of 135% on websites that have optimised and focused on usability.

Quality Assurance: The quality needs to be high
Other than user friendliness, there are technical errors that can pose huge issues and affect online purchases, registrations and downloads. The broad spectrum of browsers (Chrome, Firefox, Safari, etc.), browser versions and display sizes (smartphones, tablets, desktop, etc.) can lead issues such as graphical errors or animations that don’t function on certain browsers. It’s equally necessary to assure that your website loads quickly.

The types of websites we test

Online shops

Amazon, e-bay, etc. Online shopping is gaining more and more popularity. Online shops mainly have one goal: to persuade users to purchase their products. At the heart of the action is usually the conversion rate optimisation.

Classic websites

These contain pages that mainly provide information, such as company websites, blogs and online news sources.



Portals not only provide users with information, but also with a special login area and certain additional features. For example, a portal for a bank might include an online banking section while a gaming portal could include information regarding gamer profiles and provide varying degrees of access depending on experience.



„By crowdtesting on the right devices with the right browser versions and operating systems, Testbirds helps us deliver more customer-friendly websites and keep them customer-friendly (…) We have a continuous process of change, adjustment and improvement. Testbirds offer their testing solutions with the same flexibility and agility, which made us decide to embed their testing services continuously into our development cycle.”
Corny van de Wal, Team Manager Shop Development & Production


USABILITY & UX: Usability and UX Study
“The test results gave us very good indications of what we need to attach special importance to in further development… With the feedback we can further adapt our constantly renewed appearance to the needs of the readers”.
Johannes Vogel, Geschäftsführer Süddeutsche Zeitung Digitale Medien GmbH.



QUALITY ASSURANCE: Exploratory Bug Testing
“Working with Testbirds led to us professionalising our testing process, as it forced us to critically examine our own testing structure. It definitely made our organisation more mature in that respect. Furthermore, crowdtesting has proven to be efficient. We can start testing on a Monday and see results on a Tuesday. It’s a powerful addition to our development process.”
Lieven Swinnen, Manager e-Business Landal GreenParks
