Luke Wroblewski says that a “Mad Libs” Style Form Increases Conversion 25-40%. I’m not sure how I feel about this. I’ve seen this informal, inline type of form before but the supporting copy has always been very sparse and the number of fields limited to a couple.
The example shown was actually A/B tested, giving the 25-40% improvement. I’m not sure if this was the only form tested or not, but I’d wager there’s a novelty effect at play here. I’d love to see some more in-depth research results related to this theory.
