New feature: Personalize your test to improve response rates

Hi %YOURNAME:%,

In some situations, a test calls for a more personal welcome message than a variation of ‘Dear participant’. I’m glad to announce that as of today, our developers made this possible. We are humans after all, not machines. The sound of our name is the sweetest and most important sound in any language. If you don’t believe Dale Carnegie, believe the research that shows personalization increases response rates.

Personalize your introduction

Personalize your introduction

A personalization tag and URL

With a little bit of magic, paid accounts now have the ability to personalize the introduction and ‘thank you’ text of tests. This is done by adding a custom tag in the test, and using a personalized URL. The basic format of the personalization tag is %<variable name>:<default value>%, and the URL is customized by appending ?name=variable+name at the end of the test URL you send out. See this example:

<h1>Hello %name:you%!</h1>

Assuming the URL to start your test is http://www.usabilla.com/rate/20a/start, by adding the ‘name’ get parameter the message will be personalized, so if you direct the user to http://www.usabilla.com/rate/20a/start?name=John+Doe, the resulting message will be:

<h1>Hello John Doe!</h1>

The string between the colon and the ending percentage sign of the personalization tag is the default value, should someone access the test via the original URL, they still can get greeted the boring, impersonal way:

<h1>Hello you!</h1>

Obfuscate the URL you say? Sure.

Technical bonus for those familiar with ROT–13 and base64 encoding: these can be used by adding the letter r or b before the name= part in the URL. The John Doe in our example can be translated as http://www.usabilla.com/rate/20a/start?rname=Wbua+Qbr or http://www.usabilla.com/rate/20a/start?bname=Sm9obiBEb2U=. This way, the personalisation of the URL is not obvious. You can easily convert text to ROT-13 here, and work some base64 magic over here.

If you have any questions, don’t hesitate to ask. We will gladly help you with this new feature.
