Common Landing Page Mistakes (and How to Avoid Each One)

You've invested in traffic and built a product that solves a real problem, but the sales aren't coming. The problem may be your landing page. Mistakes that look small kill conversions every day, and most business owners don't even notice it's happening.

This guide covers the most common mistakes we see on landing pages, why they cost you sales, and how to fix each one.

1. Generic Copy That Doesn't Connect

The most expensive mistake of all: writing for everyone and convincing no one.

Why it's a problem

Visitors decide in under 5 seconds whether they'll stay on the page or close the tab. If the headline doesn't speak directly to their pain or desire, you lose their attention before you even start.

Generic copy like "The best solution for your business" says nothing. Visitors can't tell whether it's for them, feel no urgency, and don't understand what they get.

How to spot it

• Any competitor could use your headline without changing a word
• You use words like "solution," "innovative," "revolutionary" without saying what exactly
• There are no numbers, timelines or concrete results
• The text talks more about you than about the customer's problem

How to fix it

Be specific. Instead of "Boost your sales," write "Double conversions in 30 days with pages that load in 1 second."

Talk about the problem before presenting the solution. Visitors need to recognize themselves in the text before they consider buying.

Use your customer's language. If you sell to course creators, use terms like "launch," "evergreen funnel," "CPL." It shows you understand their world.

2. A Slow Page That Loses Visitors

Every second of load time cuts conversions by roughly 7%. A page that takes 5 seconds to load may be losing more than 30% of its potential sales.

Why it's a problem

Google penalizes slow pages in search rankings. Mobile users, who make up most of Brazil's web traffic, abandon pages that drag. Worst of all, you don't even know you're losing those sales, because they never happen.

Sites that load in 1 second have a conversion rate 3x higher than sites that load in 5 seconds.

How to spot it

Use Google's PageSpeed Insights. Enter your page's URL and check the score. Anything below 70 on mobile needs urgent attention.

Warning signs:

• Images that take a while to appear
• A layout that "jumps" while loading
• Buttons that only work after a few seconds
• A page that stalls on 3G/4G connections

How to fix it

Optimize images: Use modern formats like WebP, compress without losing quality, set exact dimensions. A 2MB image can easily become 200KB with no noticeable visual difference.

Minimize code: Remove unused plugins, scripts and styles. Every JavaScript library you add has a performance cost.

Use proper hosting: Cheap hosting usually means slow servers. A CDN (Content Delivery Network) makes a real difference for users in different regions.

Smart loading: Images and videos below the initial screen don't need to load right away. Techniques like lazy loading solve this.

3. A Broken Mobile Experience

More than 70% of Brazilian web traffic comes from mobile devices. If your page doesn't work well on a phone, you're ignoring most of your visitors.

Why it's a problem

"Responsive" doesn't mean "works well on mobile." Many pages technically adapt to the screen size, but the experience is terrible:

• Text too small to read
• Buttons that are hard to tap
• Forms that are impossible to fill out
• Images that crop out important information

How to spot it

Pick up your phone and try to buy your own product. Don't use the "mobile mode" of your desktop browser — use a real phone. Ask friends and family to do the same.

What to watch for:

• Can you read without zooming?
• Can you tap the buttons on the first try?
• Is the form easy to fill out?
• Do you have to scroll a lot to find important information?

How to fix it

Mobile-first design: Start by designing for the phone, then adapt for desktop. Not the other way around.

Large, well-spaced buttons: A finger doesn't have the precision of a mouse. Buttons need to be at least 44x44 pixels with space between them.

Simplified forms: Ask only for essential information. Every extra field reduces conversions. On mobile, this is even more critical.

Test on real devices: Emulators don't show the performance and touch issues that only appear on real devices.

4. A Poorly Placed or Confusing CTA

The visitor wants to buy but can't figure out how. It sounds absurd, but it happens more than you'd think.

Why it's a problem

If the buy button is buried at the bottom of the page, many visitors never get there. If there are multiple buttons with different labels, visitors get confused about which one to click.

We also see the opposite mistake: pages so packed with CTAs that they look like spam and breed distrust.

How to spot it

• The first CTA only shows up after scrolling
• There are buttons with different labels leading to the same place
• The main button competes visually with secondary elements
• There's no visible CTA above the fold

How to fix it

A CTA above the fold: Visitors need to see an option to act right away, even if they don't click yet.

Strategic repetition: Place CTAs after each important block of content, but always with the same label and destination.

Visual contrast: The main button needs to stand out. Use a color that differs from the rest of the page. If everything is blue, the CTA can be orange or green.

Specific labels: "Buy now" beats "Click here." "Start my free trial" beats "Learn more."

5. Weak or Missing Social Proof

You say your product is good. But why should the visitor believe you?

Why it's a problem

We buy from people we trust. Without social proof, visitors have only your word to go on. And on the internet, where scams are common, that's asking too much.

How to spot it

• There are no customer testimonials
• Testimonials are generic ("Great!", "Highly recommend!")
• There are no photos or details that show the testimonials are real
• No mention of customer counts, sales or results
• No logos of well-known companies that use the product

How to fix it

Specific testimonials: "I grew my sales 47% in the first month" is far more convincing than "Great product."

Context and credibility: Full name, photo, title, company. The more verifiable, the more trustworthy.

Concrete numbers: "More than 500 customers" or "R$ 2 million in sales generated" are tangible proof.

Logos and certifications: If well-known companies use your product, show it. If you have relevant certifications, display them.

Success stories: Complete transformation stories are more convincing than standalone quotes. See how we present our case studies.

6. Broken or Misconfigured Integrations

The visitor taps the WhatsApp button and nothing happens. The Facebook Pixel isn't tracking. The form submits, but you never get it.

Why it's a problem

Broken integrations mean:

• Lost leads you never even knew existed
• Ad money thrown away for lack of tracking
• A frustrating experience that destroys trust
• Bad data that leads to wrong decisions

How to spot it

WhatsApp: Tap the button yourself, on different devices. Is the number right? Does the pre-filled message work?

Pixel and Analytics: Use the Facebook Pixel Helper and Google Tag Assistant extensions. Check that events are firing correctly.

Forms: Send a test submission. Did it reach your email or CRM? Did the data come through correctly?

Payment links: Make a test purchase. Does the redirect work? Are the tracking parameters being passed?

How to fix it

Test before launch: It sounds obvious, but a basic testing checklist would prevent most problems.

Monitor regularly: Integrations break. Platforms update APIs, tokens expire, settings change. Test periodically.

Document your setup: Write down Pixel IDs, Analytics codes, API tokens. When something breaks, you need to know what was configured.

Use consistent UTMs: Standardize how you name campaigns, sources and mediums. It makes analysis and troubleshooting easier.

7. Design That Destroys Credibility

You can have the best product in the world, but if the page looks amateurish, visitors won't risk their money.

Why it's a problem

Design isn't just about "looking nice." Design communicates professionalism, attention to detail, and by extension, the quality of what you sell.

Poorly designed pages create:

• Immediate distrust
• A sense that the company is small or unstable
• Doubts about data and payment security
• A perception of low value that makes it hard to sell at fair prices

How to spot it

• Colors that clash or are hard to read
• Fonts that are too mismatched or hard to read
• Pixelated or low-quality images
• Misaligned or inconsistent layout
• Elements that look like they're from different eras
• Too much visual information competing for attention

How to fix it

Simplicity: Less is more. If you're unsure whether to add something, you probably shouldn't.

Consistency: Use at most 2-3 colors and 2 fonts. Keep spacing and sizes consistent.

Quality images: No image is better than a bad image. Invest in professional photos or use quality stock libraries.

Visual hierarchy: The visitor's eye needs to know where to go. Bigger headlines, smaller secondary text, prominent CTAs.

White space: Give it room to breathe. Elements need space around them to be noticed individually.

8. Technical Debt from Cheap Solutions

You hired a cheap page or used a free builder. It worked at first, but now:

• The page keeps getting slower
• Simple changes break other things
• Support doesn't respond or doesn't fix anything
• You're locked into a platform that won't let you leave

Why it's a problem

Cheap solutions have a hidden cost. You save R$ 500 on the build but lose R$ 5,000 in sales to poor performance. Or you spend 10 hours trying to do something a professional would do in 1 hour.

Free templates use generic code that loads unnecessary resources. Visual builders add layers of JavaScript that weigh the page down. Cheap freelancers deliver code that works today but becomes a problem tomorrow.

How to spot it

• Performance degrading over time
• Fear of making changes because "it might break"
• You can't do things that should be simple
• You depend on plugins or extensions for basic functionality
• The code is impossible to understand or maintain

How to fix it

Sometimes the best decision is to start over on a solid foundation. It sounds radical, but migrating from a problematic structure to clean code often costs less than continuing to patch it.

If rebuilding isn't an option right now:

• Document what's working and what isn't
• Remove unused plugins and scripts
• Simplify whatever can be simplified
• Plan the migration to a better solution

We build landing pages with modern technology (Next.js, React) that are fast, easy to maintain and don't lock you into a platform. Talk to us about your project.

9. No Urgency or Scarcity

The visitor liked it, but decided to "think it over" and never came back.

Why it's a problem

Without a reason to act now, the natural tendency is to put it off. And decisions that get put off rarely happen. The visitor forgets, gets distracted, finds another option.

How to spot it

• No deadline or limit is mentioned
• The offer is available indefinitely
• No incentive to buy now vs. later
• Bonuses or special terms have no deadline

How to fix it

Real urgency: Offer deadlines, limited spots, time-limited bonuses. But it has to be true. Fake urgency destroys trust.

Genuine scarcity: If you really have limited spots or stock, say so. "Last 5 units" works because it's verifiable.

The cost of not acting: Show what the visitor loses by waiting, not just what they gain by buying.

Countdown timers: They work when the urgency is real. If the timer hits zero and the offer is still there, you've lost all credibility.

10. Not Testing and Not Measuring

You launched the page and never looked at it again. You don't know how many people visit, where they click, where they drop off.

Why it's a problem

Without data, you're in the dark. You don't know whether a change helped or hurt. You don't know where the bottleneck is. You don't know whether the problem is the traffic or the page.

How to spot it

• You don't have Google Analytics or similar set up
• You don't know your current conversion rate
• You've never run an A/B test
• You don't know where your traffic comes from
• You don't monitor performance regularly

How to fix it

Set up basic tracking: Google Analytics 4 for overall traffic, plus events for key actions (CTA clicks, form submissions, checkout starts).

Define the metrics that matter: Conversion rate, time on page, bounce rate, scroll depth. You don't need to monitor everything, but you do need to monitor the essentials.

Run tests: Change one thing at a time and measure the result. A different headline, button color, form position.

Review regularly: Set aside an hour a week to look at the data. Patterns only show up when you're paying attention.

Frequently asked questions

What are the most common landing page mistakes?

Seven keep showing up: generic copy that doesn’t connect, a slow page that loses visitors before it loads, a broken mobile experience, a poorly placed or confusing CTA, weak or missing social proof, broken or misconfigured integrations, and design that destroys credibility.

How do I know if my landing page copy is generic?

Try swapping your company’s name for a competitor’s. If the text still makes sense, it’s generic: it describes a category, not your offer. Copy that converts names the audience’s specific problem in the words the audience itself uses.

Why are broken integrations so expensive?

Because the damage is silent. The page seems to work, the visitor converts, but the lead never reaches the CRM, the pixel doesn’t record the conversion and the ad optimizer starts targeting the wrong audience. You pay for traffic, lose the lead and degrade the campaign on top of it. Test the whole flow end to end before turning traffic on.

Which landing page mistake costs the most?

The ones combined with paid traffic. A slow page and broken mobile burn budget on every click, because you’ve already paid for the visitor before they even see the offer. Fixing performance and mobile is usually the highest immediate-return fix on a page that already receives ads.
