SMS API product page redesign: +12% visit-to-lead conversion
Commentary byLiftArchiveOur analysis, not theirsBandwidth's redesigned SMS API product page lifted visit-to-lead conversion by 12%.
Bandwidth's own web team ran the test, and it was published as a VWO case study.
Several changes shipped together, including a new hero, customer logos and sharper value messaging, so no single element gets the credit.
- Visit-to-lead conversion: +12% for the redesign.
- The test ran about 60 days with roughly 3,500 visitors split 50/50.
- Bandwidth rolled out the design and began moving other product pages to the same template.
- No confidence level was shared, and with about 1,750 visitors per side a 12% lift may not be statistically solid.
The change
New hero and copy, added customer logos and a clearer value proposition.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The original SMS API product page.
Variant
A redesigned page with a better hero image and tighter copy, customer logos as social proof, and a clearer statement of what Bandwidth offers.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Developer and B2B buyers look for proof that other companies trust an API. Customer logos give that proof fast.
- A stronger hero and shorter copy make the offer clear above the fold, before visitors decide whether to scroll.
- A clearer value proposition helps visitors see why this API over the alternatives.
Caveats: Bundled redesign with several changes at once. Small sample (about 3,500 visitors over about 60 days) and no significance level shared.

How to run this test on your site
- Hypothesis
- If we sharpen the hero, add customer logos and state the value proposition plainly on our product page, then more visitors will become leads because they understand the offer and trust it faster.
- Primary metric
- Visit-to-lead conversion rate
- Guardrails
- Lead quality (sales-qualified rate)
- Demo or contact form completion rate
- Time on page
- Who should test it
- B2B and API companies with product pages that drive demo or contact requests. With low traffic, expect a long test; if you can't reach a few thousand visitors per variant, consider qualitative research first.
Questions
Do customer logos increase B2B leads?
They often help because buyers want to see that similar companies already use you.
In Bandwidth's test, logos were one of several changes, so their own effect isn't known.
How long should a B2B landing page test run?
Long enough to reach a sample that can detect your expected lift, and at least one full business cycle.
Bandwidth ran about 60 days because traffic was modest.
Is it fine to test a full redesign at once?
Yes, if you want to know whether the new page beats the old one.
You just won't learn which change did the work.
