How Long Should Your Landing Page Be?

There's no ideal word count. A landing page should be as long as it takes to answer every question and objection your visitor has, and no longer. For a cheap, familiar product sold to a warm audience, that's often under 300 words. For an expensive, unfamiliar one sold to cold traffic, it can run past 4,000.

Length follows from three things you can measure: how warm your traffic is, how much you charge and how complex your offer is. Once you know those, the right length is much easier to judge.

Why isn't there one right answer?

Because the evidence points both ways. In a study of 15,981 ecommerce pages, the ones under 300 words converted best (Unbounce, 2024). For high-stakes offers it goes the other way: a long-form page for a healthcare clinic generated 220% more leads than a short page with the call-to-action at the top (MECLABS, Sierra Tucson test). The two findings describe different visitors.

So the better question is what this particular visitor needs to feel before they act. A returning customer on your email list needs a reminder and a button. A stranger from a cold ad, who has never heard of you and is being asked for £900, needs proof, a clear explanation of how it works and answers to every doubt. The copy length follows from that list of doubts, and we start with the list before thinking about word count.

When should a landing page be short?

Go short when your visitor already trusts you and the decision is easy. That usually means:

• Warm or hot traffic: people from your email list, retargeting or branded search, who already know who you are.
• A low price: under roughly £50, a free trial or a freemium sign-up.
• A familiar product: a t-shirt or a known service that needs no explaining.

A peer-reviewed study of 27,083 visitors found that shorter pages converted significantly better in a general-audience test (Dvir et al., 2018). The most aware buyers, such as your loyal customers, convert on as little as 300 to 600 words: enough for the offer, some proof and a button.

We're also firm about plain writing on short pages. Pages written at a 5th-to-7th-grade reading level convert nearly twice as well as those written at a professional level, and the penalty for dense copy is now 62% steeper than it was in 2020 (Unbounce, 2024).

When should a landing page be long?

Go long when the visitor is cold, the price is above £100 or the product is hard to grasp. Long-form pages have produced conversion lifts of 64% to 220% in controlled tests for high-consideration offers (Crazy Egg via CopyHackers; MECLABS).

Cold visitors arrive with no trust and little patience, and they decide whether to stay in about three seconds. A short page leaves out the trust-building and explanation they need. One practitioner who tracked $523M in results put it this way: a $47 product might convert with 1,500 words, while a $997 product almost certainly needs 4,000+.

A long-form page for a high-stakes decision generated 220% more leads than a short one with the CTA above the fold (MECLABS, Sierra Tucson test).

Does the fold still matter?

Yes, but less than it did. Nielsen (2024) found that 91% of users scroll, so there's no need to cram everything above the fold. Attention is still top-heavy, though: 57% of viewing time happens above the fold (down from 80% in 2010), and there's an 84% attention gap between what sits above it and what sits below (NNGroup).

Our rule is to make the promise above the fold and put the proof below it: one clear headline and one button at the top, with the evidence underneath.

Don't read too much into scroll depth either. Average scroll depth across the web is about 50% (Chartbeat), and depth alone doesn't predict whether someone buys. A sharp drop-off usually points to a weak section rather than a page that's too long.

How many calls-to-action does a long page need?

One goal, repeated down the page. On a 4,000-word page we place the same call-to-action at four or five points: after the hook, after the proof, after the offer and at the bottom, plus a sticky button on mobile. Adding a bottom CTA alone lifted conversions 16.5% in one A/B test (GrowthLayer), and a sticky mobile CTA adds around 11% (Digital Applied, 2,000-page study). Competing actions hurt. Pages with a single primary goal convert at 13.5%, compared with 10.5% for pages offering three or more (Unbounce).

FAQ

What is the ideal landing page length in words? There isn't one. Short pages (under 300–600 words) do best when visitors already know you, the price is low and the product is familiar. Long pages (3,000–4,000+ words) suit cold traffic, high prices and complex offers. Match the length to what the visitor needs.

Do longer landing pages always convert better? No. A longer page only wins when the extra length answers real objections. For warm, low-ticket audiences, pages under 300 words converted best in a 15,981-page study (Unbounce, 2024). Padding makes a page worse.

Where should I put the call-to-action? Put one above the fold, and on a long page repeat the same goal every one or two screens. A sticky CTA on mobile adds roughly 11% (Digital Applied). Avoid competing actions, since single-goal pages convert better (Unbounce).

How do I know if my page is too long or too short? List every question and objection your visitor would have before buying, then mark which ones your page already answers. If it answers all of them and nothing more, it's the right length. If one section sees heavy drop-off, fix that section instead of just cutting words.
