If you’re like me, and it’s been awhile since you were 12 and sitting in the backseat of your parents’ car, chances are you haven’t thought about Mad Libs for awhile. But there are a few people who have been implementing Mad Libs-style forms on their websites.

And early results are showing that in addition to bringing back childhood memories, they are also effective. Up to 40% more effective to be exact.

Luke Wroblewski, chief design architect at Yahoo! Inc., has written up a post on the subject on his blog. Working with vertical search platform Vast.com, Wroblewski set out to find out how these forms performed compared to standard forms:

Vast and Kelley Blue Book are among the sites that now employ this sort of form. After running some A/B testing on the traditional form versus the narrated format, they found that Mad Libs-style forms increased completion rates by 25 to 40%.

According to Wroblewski:

“Most of the input fields have stayed the same but the “comments”
text area has been replaced by a “personalize this message link” and
the phone number set of three input fields has been replaced a single
flexible input. While it’s possible these adjustments also contributed
to the increase, it’s unlikely they were solely responsible for it. As
a result, the mad libs layout likely had an impact as well.”

It makes sense that it would. A form like this takes some of the guesswork out of communicating with a business — in the case of the example above, a car seller.

Even if a task isn’t particularly difficult, any simplification can encourage completion — especially if it presents the same number of options as before. Also, presenting a little bit of a human touch can’t hurt. 

Rustin Jessen, who runs Magic in Type, created a similar form for his website and explains his motivation for using this format like this:

“I spend my day working for a huge global company with email at the
center of our communication universe. Email is a way of life in our
business, it just sort of comes with the territory. This, in and of
itself, is not a problem for me. The problem is that a vast majority of
people in this universe have no idea how to send an effective email. I
may go into more specifics on this another time… but for now let’s call
this enough information to understand why I styled my contact form this
