Case study: Remove 3 form fields – increase customer registrations by 11%


text to speech
Blivakker.no is Norway´s leading online beauty shop with approx. 20 000 visits per day. In September 2012, they performed  an A/B-test of the site registration form using Visualwebsiteoptimizer.com. They were aware that the site had an overly complicated registration process, but wanted to collect actual data to support the suspicion.

The goal

Their goal was to prove that a small change in a web form would lead to an increase in the form registration conversion rate. The hypothesis (supported by experts...) was that by reducing the number of form fields, the conversion rate would increase. If they could show a significant increase in conversion rate by making small changes to a form, they would revise the entire purchasing process.

The A/B-test

The original form had 17 form fields. They reviewed the form fields and chose to remove 3 fields immediately; account number, phone number and phone number evening. The goal was to remove even more fields, but this was difficult due to technical limitations.

They set up 3 different versions of the registration form step in the process;

  1. Control - the original form
  2. Skjema-light - the original form minus 3 form fields(account number, phone number, evening phone number)
  3. Skjema-uberlight - a completely stripped down form with fewer fields and less navigational elements

Here are the results from the A/B-test:

The Conclusion

The tests showed that when you reduce the number of unecessary fields in a form, you increase the number of registration. The test also shows that it´s not optimal to remove too much information from a form. The most important consequense of this small test is that the company now understands the importance of fast registration processes. Within a few months, more key processes will be analyzed and simplified to increase online sales.
