Landing Page Conversion Checklist: 27 Things to Fix Before You Launch

A landing page audit isn't glamorous work, but it's the highest-leverage thing you can do before launching a paid campaign. The math is simple: if your page converts at 2% and you fix it to 4%, you've just cut your cost per lead in half without touching your ad spend. No amount of creative testing or bidding optimization achieves that kind of return as quickly as fixing a broken page.

These 27 items are drawn from real audits. They're not theoretical — they're the things we find broken in the majority of pages we review. Work through them in order before you send a single click.

Above the Fold (Items 1–9)

The above-the-fold section — everything visible without scrolling — is where most landing pages win or lose. A visitor makes a judgment about whether they're in the right place within the first few seconds. These nine items determine whether they stay.

1. Clear headline that states the benefit in under 10 words. Not your company name. Not a clever tagline. A direct statement of what the visitor gets or achieves. "More leads from your paid media. Guaranteed." beats "We are a full-service digital marketing agency." every time.
2. Subheadline that adds context or proof. The headline makes a claim; the subheadline supports it. Add a qualifying detail, a timeframe, or a proof point. "We've generated 12,000+ qualified leads for service businesses across the UK and US."
3. Primary CTA visible without scrolling. The single action you want the visitor to take must be visible the moment the page loads. If they have to scroll to find it, most won't.
4. No navigation menu. Navigation menus are exit doors. Every link in a menu is an invitation to leave. Landing pages for paid traffic should have no site navigation — the only place to go is deeper into the page or to the CTA.
5. Trust signals visible above the fold. Client logos, review scores, media mentions, accreditations. The visitor doesn't trust you yet. Give them a fast reason to.
6. Load time under 2 seconds on mobile. Test on a real mobile device on 4G, not just your desktop on fast Wi-Fi. Use Google PageSpeed Insights and act on what it tells you. Slow pages bleed conversions silently.
7. Hero image or video directly supports the offer. The primary visual should illustrate the outcome or the product. Stock photos of people shaking hands in glass offices signal nothing. Show the real thing, or show a result.
8. Mobile layout doesn't require horizontal scrolling. Sounds basic. Fails constantly. Test your page at 375px width minimum.
9. Font size minimum 16px on mobile. Smaller text is a friction point. Visitors won't pinch-to-zoom to read your copy. If they can't read it comfortably, they leave.

Messaging and Copy (Items 10–18)

Getting the visitor to stay is step one. Getting them to believe your offer and want to take action is the harder part. These nine items determine whether your copy is doing its job.

10. Headline matches the ad that brought them there. This is message match — the single highest-impact factor in landing page conversion. If your ad said "Paid media for e-commerce brands" and the landing page says "Full-service digital marketing," the visitor feels disoriented. The headline should closely mirror the language in the ad that drove the click.
11. Benefits lead, features follow. A benefit is what the visitor gains. A feature is a characteristic of your product or service. "You'll generate more qualified leads" is a benefit. "We use a proprietary 12-step audit process" is a feature. Lead with benefits. Introduce features to support the benefit claims.
12. Social proof is specific. "Great service!" is worthless. "We increased our qualified leads by 340% in 90 days — James T., London" is compelling. Real names, real numbers, real outcomes. Specificity is credibility.
13. Objections are addressed before the CTA. List every reason someone wouldn't fill in the form. Address them in the copy before you ask for the conversion. Common objections for service businesses: too expensive, takes too long, already tried it, not sure it applies to my situation. Answer them directly.
14. No jargon your audience doesn't use. Read your copy aloud. Would your actual customer say these words? "Synergistic omnichannel strategy" is not how people describe what they need. Match the language of your audience, not the language of your industry.
15. Urgency is real, not manufactured. Fake countdown timers and "only 3 spots left" claims that reset every 24 hours destroy trust the moment a visitor notices. Real urgency works — limited intake, genuine deadline, actual scarcity. Manufactured urgency backfires.
16. The offer is clear — what do they get, exactly? Spell it out. "Book a free 30-minute strategy call where we'll audit your current paid media setup and give you a prioritised action list." is far stronger than "Get in touch." The more specific the offer description, the lower the perceived risk.
17. Price or price range is visible (if applicable). For high-ticket services, hiding the price creates friction at the sales stage and attracts unqualified leads. A ballpark range filters for budget-fit prospects and increases the quality of enquiries.
18. Risk reversal is prominent. A guarantee, a free trial, a no-commitment first session, a money-back policy. Something that lowers the perceived cost of saying yes. The visitor is weighing risk. Reduce it explicitly.

Form and CTA (Items 19–24)

The form is the conversion event. Every element of the form — the fields, the button, the confirmation — affects the rate at which visitors complete it.

19. Form has as few fields as absolutely necessary. Every additional field reduces conversion rate. Ask yourself whether each field is required to qualify the lead or just nice to have. For most service businesses, name, email, and one qualifying question is sufficient at the top of the funnel.
20. CTA button copy is specific. "Book my free strategy call" converts better than "Submit." "Get my free audit" converts better than "Send." The button copy should describe the action and the value in a single phrase. First person ("my") outperforms second person ("your") in most A/B tests.
21. CTA button color contrasts with the page background. The button needs to be the most visually obvious element on the page. If it blends into the background or the section colour, it won't get clicked. Contrast isn't just an accessibility requirement — it's a conversion requirement.
22. Mobile tap targets are at least 44×44px. Apple's HIG and Google's Material Design both specify 44–48px minimum tap targets. A button that's too small to tap accurately on mobile creates frustration and drop-offs. Size your CTAs generously.
23. Thank-you page confirms what happens next. After the form is submitted, the visitor needs to know: what did I just do, and what happens now? "Thanks for booking. You'll receive a calendar invite within 2 minutes. We look forward to speaking on [date]." Close the loop explicitly.
24. Form confirmation email fires immediately. An automated confirmation email should send within 60 seconds of form submission. It confirms the action, sets expectations, and keeps you top of mind. Delayed or absent confirmation emails lose leads to second-guessing.

Technical (Items 25–27)

The final three items are technical fundamentals that are easy to overlook and expensive to miss.

25. All tracking pixels are firing correctly. Verify in GA4's DebugView and Meta's Test Events tool before sending any paid traffic. A campaign running without conversion tracking is burning money with no way to optimise. This is non-negotiable.
26. SSL certificate is active. Your page must load on https, not http. A page without SSL shows a "Not Secure" warning in Chrome. Even a small percentage of visitors who notice this warning and leave represents a significant conversion loss for the budget you're spending.
27. Page renders correctly in Chrome, Safari, and Firefox on mobile. These three browsers cover the vast majority of your visitors. A layout that breaks in one browser can silently kill conversion rate on a significant share of traffic. Test manually or use a cross-browser testing tool before launch.

The Most Common Failure Points

In every audit we run, three items fail more than any others: item 1 (the headline), item 10 (message match), and item 19 (form fields).

The headline failure is almost always the same: the page leads with the company name or a vague tagline instead of a direct benefit statement. This is understandable — founders are proud of their brand — but visitors don't care about your brand name yet. They care about their problem.

Message match is the single highest-impact fix available to most pages we audit. The visitor clicked your ad because something in it spoke to their situation. If the landing page doesn't immediately confirm they're in the right place, they bounce. The ad and the landing page should feel like a continuous conversation, not a handoff between two different businesses.

The form field problem is usually rooted in the sales team asking for "qualification data" upfront — company size, budget, timeline. That information is valuable, but it's not worth the conversion rate penalty of asking for it before you've earned trust. Collect it on the call.
