The 7 UX Mistakes That Are Killing Your Conversion Rate

After running conversion audits on over 40 e-commerce and SaaS websites, I've seen the same mistakes appear with remarkable consistency. Here are the seven that cost brands the most revenue.

1. Unclear value proposition above the fold

You have 3 seconds to tell a visitor what you do, who it's for, and why they should care. Most homepages fail this test. The hero section is either too vague ("We help businesses grow") or too feature-focused.

2. Too many calls to action

When everything is a priority, nothing is. Pick one primary CTA per page and make it impossible to miss.

3. No social proof at the moment of decision

Trust signals (reviews, logos, testimonials) need to appear at the exact moment a visitor is deciding whether to act — not buried at the bottom of the page.

4. Mobile experience as an afterthought

Most teams design desktop-first and then "make it responsive." But in most categories, 60-70% of traffic is mobile. Design mobile-first.

5. Friction in the checkout or signup flow

Every additional form field reduces conversion. Every extra step loses users. Audit every step of your key conversion flow and ask: is this step strictly necessary?

6. Slow page speed

Every second of load time costs you conversions. A page that loads in 3 seconds converts significantly worse than one that loads in 1 second. Run your pages through PageSpeed Insights and fix what you find.

7. No clear next step

After a visitor reads your about page, or finishes a blog post, where do you want them to go? Most pages have no clear next step. Every page should have a defined exit intent.
