Your website loses customers for predictable reasons: it loads too slowly, it does not say what you do, it frustrates people on phones, and it gives visitors no reason to trust you. None of that is guesswork. Research from Google, the Nielsen Norman Group, and the Baymard Institute puts numbers on each one, and every one of them is fixable.
1. Slow Load Times Kill Conversions
When the BBC studied its own traffic, it found it lost an additional 10% of users for every extra second the site took to load. The upside is just as real: Vodafone improved its Largest Contentful Paint by 31% and sales rose 8%, and Rakuten 24 grew revenue per visitor by 53% after passing Core Web Vitals thresholds. All three results are documented in Google's web.dev case studies (see Sources below).
Google's current targets are concrete: main content visible (LCP) within 2.5 seconds, response to taps and clicks (INP) within 200 milliseconds, and layout shift (CLS) under 0.1, measured at the 75th percentile of real visits.
The fix: Compress and resize images (WebP or AVIF), serve your site through a CDN, cut unused JavaScript, and lazy-load anything below the fold. A modern framework like Next.js handles most of this out of the box.
2. No Clear Value Proposition
The Nielsen Norman Group, drawing on an analysis of more than 200 million page visits, found the first 10 seconds are decisive. If a page does not communicate its value in that window, most visitors leave. Those who stay past 30 seconds often stay for minutes. And a study from Google researchers found that people form a judgment of a site's visual appeal within 50 milliseconds, before they read a single word.
The fix: Lead with a clear, benefit-driven headline. Tell visitors exactly what problem you solve and who you solve it for. Generic openers like "Welcome to Our Website" waste the only seconds that matter.
3. Poor Mobile Experience
Google uses the mobile version of your site, crawled with a smartphone agent, for indexing and ranking. Cloudflare's network data shows 43% of all web requests came from mobile devices in 2025, up from 41% the year before. If your site has tiny tap targets and unreadable text on a phone, you are failing both Google and a huge share of your audience.
The fix: Design mobile-first and test on real devices. WCAG 2.2 sets the accessibility floor for tap targets at 24 by 24 CSS pixels; treat that as a minimum and make primary buttons comfortably larger. Keep text readable without zooming and navigation reachable with a thumb.
4. Weak or Missing CTAs
If visitors can't figure out what to do next, they leave. Every page needs a clear call to action, whether that's booking a call, requesting a quote, or downloading a resource.
The fix: Use one primary CTA per page. Make it visually prominent with contrasting colors. Use action-oriented language ("Get Your Free Audit" beats "Submit").
5. No Trust Signals
The Baymard Institute's meta-analysis of 50 studies puts average cart abandonment at just over 70%. Among the fixable reasons, 19% of US shoppers said they did not trust the site with their credit card information, and 17% abandoned because of website errors or crashes. Stanford's Web Credibility Project, built on research with more than 4,500 participants, found that people judge a site's credibility largely on its visual design, and recommends showing the real people behind the site, a physical address, and clear contact information.
The fix: Add social proof throughout your site, not just on a dedicated testimonials page. Show real results, real people, and real numbers. Make your contact details easy to find.
