Data-driven CRO: what 100 landing page audits taught us

After auditing over 100 landing pages across B2B services, SaaS, and professional services, the same patterns keep appearing. The problems are rarely unique. The fixes are largely predictable.

Here’s what actually moves conversion rates.

The most common issues, by frequency

1. Unclear primary action (found in 78% of audits) The page has multiple competing CTAs — “Get started”, “Learn more”, “Schedule a demo”, “Download the guide” — all with equal visual weight. Visitors don’t know what to do, so they do nothing.

Fix: one primary CTA per page. Secondary actions exist but are visually subordinate.

2. Features, not outcomes (67%) “Automated lead scoring” is a feature. “Know which leads are ready to buy before your competitors call them” is an outcome. Visitors buy outcomes. They evaluate features after they’ve decided to buy.

Fix: rewrite every feature claim as an outcome. Ask “so what does that mean for me?” until you reach the real benefit.

3. No proof above the fold (61%) The visitor is skeptical. The hero section asks them to trust you before giving them any reason to. Logos, a specific result, or a short testimonial above the fold addresses this before the visitor has decided to leave.

4. Form friction (54%) Forms with more than 4 fields, required phone numbers on cold traffic, CAPTCHAs, and no privacy note next to the email field all reduce submission rate measurably.

Fix: minimum viable fields. Phone is a close rate optimization — collect it after the lead is warm.

5. Load time on mobile (49%) Half the sites we audit have LCP over 4 seconds on a mobile connection. At that point, the CRO work is theoretical because half the visitors have already left.

The compound effect

These fixes rarely work in isolation. The highest-converting pages do all of them:

• Single clear CTA
• Outcome-oriented copy
• Proof in the first viewport
• Minimal form friction
• Sub-2.5s load time

A page that’s mediocre on all five dimensions typically converts at 1–2%. A page that’s strong on all five can reach 8–12% for qualified traffic. That’s the difference between a business that struggles and one that scales.

Audit before you redesign. The data usually tells you what to fix. For B2B SaaS teams in particular — where a 2× conversion lift on the demo-request flow rewires the entire growth model — the Sweden B2B SaaS market page covers the per-vertical CAC and conversion-rate benchmarks we use.
