MWITA-CUX-2026-007 · Evidence A · P1
Two randomized web experiments found that shorter commercial landing pages generated significantly more lead-form submissions than longer information-rich versions across locations and observation periods.
What this does not establish
The measured conversion was personal-data form submission, not purchase, revenue, lead quality, refund or retention. Page length bundled multiple information elements, and geography/product details constrain transfer.
Counterevidence & uncertainty
More product and service information did not improve the measured form outcome; however, absence of downstream sales data prevents concluding that shorter pages maximize business value.
What would change the reading
Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral or commercial outcomes.
