What can you test?

For these tests you can use RapidUsertests

Do you already know all the ways you can use RapidUsertests to optimize your website or app? We'll show you interesting use cases here that you might not have thought of yet. 

We also present some of these use cases in detail in our webinar "Hacking UX: Advanced UX Testing".

Testing mobile websites

It's likely that your users will also want to visit your website via their smartphone or tablet. How user-friendly is your mobile site? 

Recommendation: Examine your mobile experience for smartphones and tablets. You can also analyze the multi-device experience with RapidUsertests.

Testing prototypes

Early testing helps to offer user-friendly from the beginning. Timely optimization saves you time, effort, and stress during development or after launch. For testing prototypes that require explanation, we recommend moderated RapidUsertests.

Recommendation: Test mockups and prototypes at the earliest. Make designs accessible to testers via a URL. If a login is required, provide the login data directly in the first test task (click here for other Best Practices for testing with prototypes).

Testing unpublished apps

Your app is still unpublished? The sooner you test your app with real users from your target audience, the better because you'll find problems early and can fix them more easily.

Make your unpublished app available to iOS users as a beta iOS app on the Testflight platform. Users install the Testflight app and then open the "Public Link" you provide to install the unreleased app.

Android users can install unreleased apps if they agree to install apps of unknown origin in their device management settings. In the test, you can provide the apk file for download. Ask the testers to uninstall the app after the test.

Testing apps or websites with access data

If all test persons can use the same access, then insert the access data into the test scenario. 

If each test person needs their own credentials, then we recommend including an editable table with individual credentials in the test. This is a template for access data.

Provide more credentials than testers in case something goes wrong and a tester needs another credential. 

Compare multiple versions

Do you want to be sure which version of your design or navigation users will find the best? Then set up a test in which you compare several design concepts with each other.  

To avoid an order effect, use randomization of the tasks (expert features) or set up two tests and change the order. It is advisable to ask for the preference for a version in written form in the post-survey.

Learn from the competition

What does your competitor do better than you? What are your strengths? What do your users say in a direct comparison? Test your own website or app and those of your main competitor.

Recommendation: Have the testers do the same tasks on each website/app. Ask them about the pros and cons of both and which solution they prefer. Of course, you can also test only your competitor to examine the strengths and weaknesses in detail and understand them better (Tips for competitor testing).

Search intent analysis: test Google search results

The majority of all search queries are made via Google. Test how well your website is found with Google and how the results or ads affect your users.

Recommendation: Use Google as a starting page and let your users search for products and keywords for which you are listed. Ask the test subjects which search results they would choose to click on and why.

Gather the first impression

Already in the first 5 seconds, a user decides whether he likes a website and stays or rather leaves the page. Evaluate how your brand is perceived, whether the page is trustworthy or what exactly is seen on the start page or landing page.

Recommendation: start with a 5-second test of your Homepage or Landingpage and ask the testers afterward what they remember and what impression they got. Just contact us via our chat if you have any questions about this.

Test search function

What do online store visitors use 90% of the time on a website? That's right, the search function. A robust search function is important for every online store. In one study, we discovered the weaknesses of many search functions.

Recommendation: Test your search function with as many search queries as possible. Look for realistic scenarios, category search queries, and words with high relevance to your site. Give the testers scenarios, but give them enough freedom to try out their own search phrases as well. 

Perform card sorting

Card sorting is also possible with RapidUsertests if you provide the Testers with an appropriate tool. For example, we have had a good experience with Optimal Sort.  

Miro is another good option, but Testers have to register a free account in advance.

Testing checkout process

Do you meet all the requirements for a simple payment process? How easy is your order form to understand? Find out the essential criteria for optimizing your checkout with a usability test.

Recommendation: Be sure to inform the testers that they should not complete the order ("Do NOT click on 'Buy now") or provide them with your address and credit card number if you also want to test the last step of the checkout.

Testing newsletter and other mails

Newsletters can be the gateway to a particular offer for your customers. What appeals to them in particular and what are the requirements for a newsletter? Read our study on the success factors of good newsletters.

Recommendation: Test the newsletter registration and the entire newsletter for user-friendliness. Another possibility is to compare different drafts or compare with competitor newsletters to find out the best information transfer and most appealing presentation.

Testing registration process

For data protection reasons, our testers are advised not to disclose their real data, but to use realistic but fictitious data.  Nevertheless, we recommend explicitly pointing this out again in the task definition or providing test data.

It is often necessary to confirm the e-mail address before the registration can be continued. To perform the confirmation, the testers can use tools like muellmail.com or byom.de. You can use this text to instruct the testers:

"Open a new tab and go to www.muellmail.com. Create a disposable email address there, go back to the registration form, and enter the email address there. In your disposable mail account on muellmail.com you will now receive an email and you can confirm your registration. Emails from a disposable mail account are automatically deleted after a few hours or a few days."

Conduct long-term studies

Some UX problems, especially with apps, only become apparent during regular everyday use. Here, too, RapidUsertests are suitable for finding out what motivates users to use the app continuously or what keeps them from doing so.

Recommendation: Start with a user test that is limited to first impressions and comprehensibility. Then give the testers the task of using the app on a day-to-day basis over the course of a few weeks and conclude this testing period with a second user test. For more information, see our blog article on using crowd usability testing for long-term studies.

Interview existing customers, employees or own testers

You can also invite your own testers to RapidUsertests. For example, you can test power features or revisit features with your existing customers. Your own employees can also provide valuable feedback - if they are not too familiar with the test subject.

Recommendation: Invite your existing customers or employees to test your site. Look over their shoulders as they use your site and get valuable feedback. We promise you one or two "aha"-experiences! 

Testing software

RapidUsertests are suitable for all digital products. You can also test B2B or B2C software, regardless of the industry. Because only user-friendly software is actually used (with pleasure).

Recommendation: Test how user-friendly your software is to avoid subsequent changes. Satisfied users are more likely to recommend your software to others.

Testing internationally

Do you have international users? Even in Western nations, cultural differences can cause misunderstandings. Therefore, be sure to conduct usability tests in the countries with the highest number of users or if you are planning to enter the market in a new country.

Recommendation: You can also conduct desktop tests with RapidUsertests in Austria, Switzerland, France, Great Britain, and the Netherlands. Other countries are available on request.

Testing advertising effectiveness

Do you want to start a new advertising campaign, but want to know beforehand how it will be accepted by your target group? RapidUser tests can also be used for this purpose - no matter whether flyer, advertisement, commercial, landing page, etc.

Recommendation: Simply provide the testers with the advertising product via a link and ask them for their impression. What do they notice positively, what negatively, and do they feel motivated to buy? Advertising tests can also be combined well with 5-second tests and quantitative surveys.

Mystery calls

How do users get on with your hotline? You can also find this out with RapidUsertests by having test persons call your customer service. Tell the test persons to record the test with their laptop microphone and to put their phone on speaker.

IMPORTANT: As long as the test subjects make calls with bots, there are no privacy issues. However, the customer service representatives must have consented to the recording. If this is not the case, you must instruct the test subjects to hang up as soon as they are connected to a real person.


As you can see, almost all touchpoints during the customer journey can be analyzed and optimized with RapidUsertests. Use this overview as inspiration for your next test. And if you have any questions, just contact us. We will be happy to help you!
