The basics are where pages leak
Most underperforming landing pages are not failing because of some sophisticated issue — they are missing a handful of basics that quietly kill conversion. Things like a clear headline, visible trust signals, and an obvious call to action are easy to get wrong or overlook, and any one of them can cap a page's performance. A systematic checklist that covers these fundamentals catches the leaks before you waste time on advanced optimization.
This is good news, because it means fixing landing pages is often straightforward. Before running elaborate tests, working through a checklist of basics surfaces the obvious problems holding the page back — and fixing those usually delivers bigger gains than any clever experiment on a fundamentally flawed page.
Win above the fold
The most important section is above the fold, where visitors decide in seconds whether to stay. The essentials here are a clear headline that matches the intent of whatever brought the visitor, a supporting subheadline that conveys benefit and proof, and a visible, obvious primary call to action. If a visitor cannot immediately grasp what the page offers, who it is for, and what to do next, the page fails before they scroll — no matter how good the content below.
Getting the above-the-fold basics right is the highest-leverage part of the checklist. Headline-intent match alone resolves a huge share of landing-page underperformance, because a mismatch between the ad or source and the page sends visitors straight back.
Fix basics before chasing tests
The discipline the checklist enforces is fixing fundamentals before chasing advanced optimization. Trust signals, clear CTAs, intent-matched headlines, mobile usability, and load speed are basics that, when missing, undermine everything else. Running an elaborate A/B test on a page that lacks these is optimizing the wrong layer — like adjusting the trim on a car with no engine.
So work through the checklist systematically, fixing each missing basic before moving to clever experiments. The fundamentals — clear above-the-fold messaging, trust, a single obvious CTA, fast mobile-friendly delivery — do most of the heavy lifting in conversion, and getting them right typically outperforms sophisticated optimizations layered on a broken foundation. Master the basics first, then optimize from a page that actually works.
Common mistakes that quietly kill results
These come straight from audits we run every week. If any of them stings, you’re in good company — and the fix is usually faster than you think.
Testing button colors while the offer is broken. No shade of green fixes a value proposition nobody wants. Fix message-market fit first — headline, offer, proof — then micro-optimize.
No losing-test archive. Teams re-run dead ideas every time someone new joins. Keep a one-line log: hypothesis, result, date. Your test velocity doubles when you stop relitigating history.
Form fields nobody questioned. Every field costs completions. Phone number 'required' on a lead form typically cuts submissions 15-25%. Ask: would we rather have this data or this lead?
Redesigning instead of iterating. Full redesigns reset everything you've learned and usually dip conversion for weeks. Ship the redesign as a series of tested changes and keep the wins, kill the losses.
From the trenches
A SaaS pricing page test: changing 'Start free trial' to 'Start free — no card required' lifted signups 19%. The objection was already in users' heads; the button just answered it.

Frequently asked questions
Why is my landing page not converting?
Usually it's missing a few basics — a clear intent-matched headline, visible trust signals, an obvious CTA, or fast mobile delivery. These fundamentals cap performance and should be fixed before advanced testing.
What should a landing page have above the fold?
A clear headline matching the visitor's intent, a benefit-and-proof subheadline, and a visible primary call to action. Visitors decide in seconds, so above-the-fold clarity is the highest-leverage element.
Should I A/B test or fix the basics first?
Fix the basics first. Running elaborate tests on a page missing fundamentals optimizes the wrong layer. Clear messaging, trust, and an obvious CTA usually outperform clever experiments on a broken page.
