1. Pass the 5-Second Test
Show your landing page to someone who has never heard of your product. After 5 seconds, ask: what does this do, and who is it for?
If they can't answer both questions clearly, your hero copy needs work. The headline should state the outcome, not the feature. Sub-headline adds specificity: who it's for, how it works, or what makes it different.
Example: ✗ "The next-generation workflow platform" ✓ "Close support tickets 3× faster, without adding headcount"
The most common reason a headline fails the 5-second test is that the founder wrote it after months of working on the product. At that point, every word seems obvious and specific. Fresh eyes reveal that "workflow platform" means nothing to someone encountering the product for the first time. Recruit 5 people outside your immediate circle to test the headline, friends and colleagues are too familiar with your pitch to give you reliable feedback.
2. One Page, One Conversion Goal
Every element on the page should serve one goal. If your goal is "book a demo", remove everything that doesn't help a visitor decide to book a demo.
This means: no blog links in the nav (use a minimal nav or no nav at all on landing pages), no social media icons in the footer, no "Read our case studies" unless they're directly on the page.
In WeWeb: build landing pages as separate pages from your main site and strip the nav down to logo + one CTA button.
Leakage is the conversion killer that most teams overlook. A landing page for a paid ad campaign with standard site navigation leaks 15–30% of visitors who click to the homepage, blog, or pricing page and never return to the original conversion path. For high-spend campaigns, removing the full navigation in favour of a stripped landing page consistently improves conversion by 10–20%. The visitors who genuinely want to explore further will scroll down the page, you don't need to offer them an escape route.
3. Put Social Proof Above the Fold
Social proof doesn't belong at the bottom. Move it directly below the hero, before the feature section.
For early-stage products: "Trusted by teams at X, Y, Z" with 3 company logos works even if those are just beta users. If you have no logos yet, use a testimonial from a beta user or early customer instead.
For later-stage products: a row of logos + a key metric ("4.9★ on G2", "2,000+ active users") is the highest-converting combination.
The psychological mechanism is authority transfer: the credibility of a recognised brand name transfers partially to your product when placed alongside it. This is why enterprise SaaS companies pay heavily for case studies with Fortune 500 customers, even a small deployment at a large company legitimises the product for all prospective mid-market buyers. For early-stage products, press mentions ("As seen in TechCrunch") or accelerator badges ("Y Combinator W25") serve the same authority-transfer function.
4. Write Benefit-First Feature Bullets
Feature bullets are the most-read section after the hero. Most teams write them feature-first:
✗ "AI-powered inbox sorting" ✓ "Inbox zero in 20 minutes, AI sorts and labels every email automatically"
The format is: [outcome], [feature that delivers it]. Visitors read the outcome first. If the outcome resonates, they read the feature to understand how.
For a landing page driving cold traffic, prioritise the top 3–4 most universally resonant outcomes. Avoid niche benefits that only matter to power users, those visitors will find them during the trial. The goal of bullet copy on a cold-traffic landing page is to get enough visitors curious enough to click the CTA. It is not to explain every capability of the product. More bullets is not better: 4 well-written benefit-first bullets outperform 12 feature-first bullets in every test we have run.
5. Use a Single, Specific CTA
"Get started" is weak. "Start your free 14-day trial" is strong. "Book a 20-minute demo, no sales pitch" is even stronger for high-ACV products.
Specificity reduces friction because it sets expectations. The visitor knows exactly what happens when they click.
In WeWeb: use a sticky CTA button in the header that appears after the user scrolls past the hero. A/B test the button copy using a WeWeb variable and a simple Make webhook to track clicks.
High-ACV products (€200+/month) consistently convert better with demo CTAs than free trial CTAs, because complex enterprise software requires human explanation to reach an activation moment. Low-ACV products (€20–50/month) convert better with self-serve trial CTAs, the economics of a sales call don't justify the deal size. If you're unsure which camp you're in, run both as A/B variants for 4 weeks. The data will tell you which path your market prefers.
Headline Formulas That Convert
There are four headline structures that consistently outperform others on SaaS landing pages, and they are worth knowing before you start writing.
The Outcome Formula: "[Specific result] in [timeframe], without [undesired effort]". Example: "Launch your SaaS MVP in 6 weeks, without hiring a developer". This works because it names the dream outcome, sets a credible timeframe, and removes the most common objection in a single sentence.
The Problem Flip: "Stop [painful current state]. Start [desired state]". Example: "Stop wasting Mondays in standups. Start shipping features your customers actually asked for". This format works because it acknowledges the visitor's current pain before positioning the product as the escape route. It is especially effective for products that replace a frustrating existing workflow.
The Social Proof Headline: "[Number] [type of customer] use [product] to [outcome]". Example: "600 European startups use WeWeb to build production apps without code". This format leads with social proof and embeds the outcome simultaneously. It works well for products with an established customer base but struggles at the earliest stage when the numbers are not yet impressive.
Hero Image Strategy
The hero image or visual is the second most important element on the page after the headline, and most teams treat it as an afterthought. A strong hero visual reinforces the value proposition; a weak one undermines it even if the copy is excellent.
Product screenshots consistently outperform illustration and stock photography for SaaS landing pages. A real screenshot communicates immediacy, visitors can see the actual interface they will be using, and signals transparency. The screenshot should show the product at its most impressive moment: a completed dashboard with data, a polished feature in action, or a before-and-after comparison. Never show a blank state or an empty onboarding screen in your hero.
For products that are genuinely hard to screenshot (background processing tools, APIs, infrastructure services), use an abstract visual metaphor built from the product's output. A data pipeline tool might show a visualised data flow diagram. A communication API might show a message thread. The goal is to give the visitor a mental model of what the product does, not to literally screenshot it. In WeWeb, use an absolutely-positioned image component on the hero with overflow hidden on the section, this creates the "floating screenshot" effect common on high-quality SaaS sites.
CTA Button Copy Testing
Button copy is the highest-leverage copywriting on a landing page because it is the last thing a visitor reads before committing. Small copy changes produce outsized results, we have seen 30–50% conversion rate differences from a single word change on a CTA button.
The principle is specificity plus low commitment. "Get started" is vague and creates uncertainty. "Start my free trial" is specific and uses "my" which creates a sense of ownership before commitment. "Try free for 14 days" removes the word "trial" (which implies it will end) and leads with the action (try) and the benefit (free). Each of these framings changes the psychological calculus slightly.
For systematic improvement: run each variant for a minimum of 1,000 unique visitors before drawing conclusions. Use a WeWeb variable to control which copy variant is shown and a Make or PostHog event to track clicks by variant. After 2–3 rounds of testing, you will typically find one copy formulation that clearly dominates for your specific audience and offer. Lock it in as your default and move on to testing a different page element.
Mobile-First Landing Page Design
Mobile traffic to SaaS landing pages has grown steadily for a decade and now accounts for 50–65% of visits for most products. The implication is clear: designing desktop-first and adapting for mobile is the wrong approach. Design at 375px and scale up.
The most common mobile landing page failures we audit: hero text overflowing the viewport width because the headline was written for desktop; CTA buttons that are smaller than 44px tall, making them difficult to tap; feature grids that attempt to show four columns on mobile, compressing each card into an unreadable sliver; and hero images that are larger than the viewport, causing horizontal scroll.
In WeWeb, open the responsive preview at 375px from day one of the build. Set font size variables with breakpoint overrides: H1 at 56px desktop, 40px tablet, 32px mobile. Use a single-column layout for all sections at mobile, switching to multi-column at 768px. The sticky header CTA should be full-width on mobile and fixed to the bottom of the viewport (position: fixed, bottom: 0, width: 100%), this is the pattern used by the highest-converting mobile landing pages.
6. Optimise for Mobile First
Over half your landing page visitors arrive from mobile, especially if you run LinkedIn or Meta ads. Design for a 375px screen, then scale up.
Key mobile checklist: - Hero headline under 50 characters - CTA button at least 48px tall - No horizontal scroll - Font size minimum 16px for body text - Images load under 2 seconds on 4G
WeWeb's responsive preview lets you design at 375px, 768px, and 1280px simultaneously. Use it from the start, retrofitting mobile on a desktop-first build wastes hours.
Test your landing page on a real device, not just the browser's device simulation tool. Browser simulations do not accurately replicate touch scroll behaviour, font rendering at physical pixel densities, or the visual weight of UI elements at real scale. Borrow a low-end Android phone to test in addition to your iPhone, a €150 Android represents the device most of your users are actually holding.
Page Speed Impact on Conversion
The relationship between page speed and conversion is direct and well-documented. Google's own research shows a 7% drop in conversion for every 1-second increase in load time. For a landing page receiving 1,000 visits per week at a 3% baseline conversion rate, a 2-second slowdown costs 4 leads per week, or roughly 200 leads per year.
The most impactful performance optimisations for no-code landing pages are image compression and third-party script management. Images should be served as WebP format at 2x the display size for retina screens, and compressed to under 200KB for hero images. Use WeWeb's built-in image optimisation pipeline, it handles WebP conversion automatically. Third-party scripts (chat widgets, heatmap tools, tag managers) are the invisible performance killers: each one adds 100–300ms to load time and can cause layout shift that hurts both UX and Core Web Vitals scores.
Target a Lighthouse performance score of 90+ and a Largest Contentful Paint under 2.5 seconds before launching any paid campaign. A slow landing page is waste, you are paying to bring visitors to a page that loses them before they even read the headline. Fix performance before scaling spend.
7. Add a FAQ Section
A FAQ section reduces the most common objections before they become reasons to leave. It also ranks for long-tail queries in Google.
The 5 questions every SaaS landing page FAQ should answer: 1. How long does setup take? 2. Do I need a credit card to start? 3. What happens when my trial ends? 4. Can I integrate with [most common tool in your category]? 5. How is my data stored and secured?
In WeWeb: build the FAQ as an accordion component using a Supabase table, this lets you update questions without redeploying the page.
FAQ content comes from real objections. The best source for FAQ questions is your sales call recordings and support ticket history. Every time a potential customer asks a question before converting, it belongs in the FAQ. If you are pre-launch, use ChatGPT to brainstorm objections for your specific category, it is a surprisingly good proxy for real user concerns when you don't yet have conversion data.
8. Speed Is a Conversion Factor
A 1-second delay in page load reduces conversions by 7% (Google, 2023). For a landing page driving ad traffic, that's significant.
WeWeb pages are static-exported by default, they load from a CDN and are extremely fast. The main culprits for slow WeWeb pages are: - Unoptimised images (compress to WebP before upload) - Too many third-party scripts (chat widgets, analytics, load them deferred) - Large video files in the hero (use a short looped MP4 under 2MB, or a static screenshot)
Target: Lighthouse performance score above 90 before going live.
A quick speed audit takes 10 minutes: open Chrome DevTools, go to the Network tab, load the page, and sort by file size. The largest files are almost always unoptimised images. Fix those first, they deliver the biggest performance improvement for the least effort. Once images are optimised, look at the third-party script count. If you have more than 3 external scripts, audit each one for necessity. A chat widget you installed six months ago and never configured is not worth 300ms of load time.
9. Track the Right Metrics
Conversion rate is the top-line number, but these secondary metrics tell you why:
Scroll depth: are visitors reaching the pricing section? If not, the hero isn't compelling enough to continue reading. CTA click rate: of everyone who sees the CTA, what percentage clicks? Benchmark: 2–5% for cold traffic, 10–20% for warm traffic. Form abandonment rate: if visitors start the form but don't submit, a field is creating friction. Reduce to the minimum required fields.
Set these up with a simple Plausible or PostHog integration in WeWeb, both have no-code WeWeb plugin connectors.
Review your landing page metrics monthly rather than daily. Daily numbers are too noisy to draw conclusions from, a single spike in bot traffic or a shared link in a Slack community can distort a day's data completely. Monthly reviews give you enough volume to identify genuine trends and make confident decisions about what to test next. Keep a log of every change made to the page with dates, so you can correlate changes to conversion movements.
