ApexureA long form landing page beats a short one when visitors need persuading: the offer is costly, risky or unfamiliar, and they arrive with questions.
A short page wins when visitors already know what they want and every extra section just delays the click.
In our database of SaaS and lead-gen tests, cutting content won more often than adding it, but the biggest single lifts came from adding the right information to pages that were too thin.
This hub covers 33 tests tagged for page length, copy length and content order across SaaS and lead-gen sites.
27 variants won, 2 lost and 4 showed no clear difference.
The full list is in the grid on this page.
Below is what those results have in common and how to run your own test.
Long form vs short form landing page: what the tests show
"Long vs short" sounds like one variable, but in practice it never is.
Every length test adds or removes specific content: an FAQ, testimonials, screenshots, a second CTA, an agent Q&A. The results make more sense when you ask what content changed and whether visitors needed it.
When the longer page won
The largest lift in this set came from adding depth.
HealthSpire, a Medicare call-center business owned by Aetna, worked with MECLABS Institute to test a short page that listed products against a longer page with product-level value copy, agent photos, tips and a Q&A with an agent.
The long Medicare landing page produced +638% leads.
Medicare is a confusing, high-stakes choice, and the short page answered almost none of the questions visitors brought.
MarketingExperiments saw something similar with a physicians-only network that sold research access.
Its multi-page microsite made visitors click through several steps to find information.
Merging most of it into one long page with the value proposition and form ask up front lifted the lead rate +155%.
That test bundled several changes, so length is only part of the story.
PayPanther replaced a bare pricing and sign-up page with a longer page adding pricing FAQs, testimonials and a no-risk trial CTA, for +372.6% sign-ups.
Treat that number with care: it came from about 1,000 visitors over a month, with three additions at once.
The same pattern shows up outside landing pages.
M7 Corporation found that a long-copy white paper email, including a table of contents, was roughly 3x more effective than the short version for enterprise developers.
The company itself warned that this audience reads a lot and the result may not carry over.
When the shorter page won
Most wins in this set came from cutting.
TheHOTH stripped its homepage down to just the account sign-up form and saw sign-ups go from 1.39% to 13.13% over 30 days and close to 3,000 visitors.
Two caveats from the source: most of that traffic was already brand-aware, and the team raised concerns about lead quality from the minimal page.
Penn Foster sent brand search ads to a dedicated, fast-loading page with less information and two clear CTAs instead of the homepage.
The click-to-lead rate rose +202% on about 35,000 visitors over 24 days.
Again, these were people who searched for the brand by name.
Apexure tested a short Book a Demo page for Flare, a cybersecurity SaaS, with only a headline, customer logos and a form.
It replaced a long page with testimonials and FAQs that was hard to use on mobile, and the short page lifted conversion rate +65%.
The test ran for about a week, which is short.
Someone who clicks "book a demo" has already decided; a long page asks them to decide again.
Smaller, steadier lifts came from trimming rather than gutting:
- Apexure's shorter page for Reclaim My PPI Tax took end-to-end conversion from 1.02% to 1.77%.
- KlientBoost moved benefits up and cut low-value long content for a lead-gen client, raising step-1 conversion from 37.26% to 40.40%.
- MoneYou removed information tabs from a savings landing page and moved sign-ups from 9.69% to 11.13% (+14.86%), bundled with a copy fix.
- Markitekt's shorter Designboost homepage for a free course offer got +13% email sign-ups and +25% click-through to the courses page.
- Voices.com removed a featured-talent section from its homepage for +33% sign-ups, and +28% on a retest. The rerun makes this one of the more trustworthy results here.
What lost or went flat
The two losses are the most useful results on this page.
AssessmentDay ran a multi-arm test on an affiliate landing page.
Removing the FAQ section gave +62% sales and removing the screenshots gave +56%.
But removing both cut sales about 3%. Each section was dead weight on its own, but the page needed at least one of them.
If you only ran the two single-removal tests and shipped both, you would have lost the gains.
Sage France stripped product category listings to titles only and got fewer clicks into product pages; visitors hesitated more without the descriptions.
And Alma Media tested a minimal paywall explanation against a moderate and a detailed one.
The team expected the minimal version to win, but the medium amount of explanation beat both. No numbers were published.
The flat results were mostly newsletter copy tests from MarketingSherpa and MarketingExperiments, where short and long versions drew about the same clicks.
Booking.com moving registration steps higher on its partner join page also showed no lift.
Short vs long landing page: how to pick and how to test
The pattern behind the results
Across these tests, the winning length tracked two things: how much the visitor already knew and how much the decision cost them.
| Situation | What tended to win | Example from the database |
|---|---|---|
| Brand-aware or high-intent traffic | Short page, clear CTA | TheHOTH, Penn Foster brand search |
| Visitor already chose the action (demo, free sign-up) | Short page with a form and trust cues | Flare demo page, Designboost free course |
| Confusing or high-stakes purchase | Long page that answers doubts | HealthSpire Medicare, Carglass homepage |
| Pricing or commitment page with open questions | Longer page with FAQs and proof | PayPanther pricing page |
| Information spread across clicks or tabs | One page, value up front | Physician network microsite |
AGConsult's Carglass Belgium test fits this neatly. The winning homepage looked busier, but it answered visitors' main doubts about booking a glass repair and drove more online appointments. The source gives no figure.
In other words, the variable isn't word count.
It's whether the page answers the questions standing between this visitor and the action.
Short pages win when those questions are already settled.
Long pages win when they aren't, and the extra content addresses them directly.
This is also why matching the page to the ad matters: Penn Foster's short page worked because the visitor's question was already "how do I enroll," not "what is Penn Foster."
Why scrolling isn't the problem people think
A common argument for short pages is that nobody scrolls.
Nielsen Norman Group's 2018 eyetracking study found users spent about 57% of page-viewing time above the fold and 74% in the first two screenfuls.
So people do scroll, but attention drops fast.
That supports putting the value proposition and CTA at the top of a long page, as KlientBoost and the physician network did. It doesn't mean long pages fail.
The real cost of extra content is cognitive load: each section is one more thing to read and judge.
Content that answers a live question earns that cost.
Content that doesn't, like the featured talent on Voices.com or the FAQ at AssessmentDay, only adds friction.
How to run a page-length test
- List the questions first. Use sales calls, chat logs and on-page surveys to find what visitors ask before converting. Each section on the long version should answer one of them.
- Test sections, not just pages. Remove or add one block at a time where traffic allows. AssessmentDay shows why: single removals won, the combined removal lost.
- Try a middle version. Alma Media's medium paywall copy beat both extremes. A three-arm test (short, medium, long) costs more traffic but tells you much more.
- Measure past the click. Short pages can raise form fills while lowering lead quality, as TheHOTH noted. Track qualified leads, demos held or paid conversions, not just submissions.
- Segment by traffic source. Brand search and cold paid social visitors need different amounts of information. A blended result can hide a win in one segment and a loss in the other.
- Size the test properly. Several results here came from small samples or one-week runs. Check the traffic you need with the sample size calculator before you start, and run for full weeks.
- Keep the top of the page constant if you can. When the hero, headline and CTA change along with length, as in the bundled PayPanther and physician network tests, you can't tell which change did the work.
If you're deciding what to cut, start with the sections our tests most often flagged as removable: FAQs placed before the CTA, screenshot galleries and featured-profile blocks.
Our FAQ tests show the same section can help or hurt depending on where it sits.
