A website doesn't have to look broken to be losing you customers — it just has to be slow, hard to use on mobile, or mismatched with what brought someone there in the first place. Below are five concrete, checkable signs, each with a specific number or test you can verify yourself today, not vague warnings to take on faith.

Sign 1: Your Page Takes More Than a Few Seconds to Load

Under 2 seconds is good. Between 2 and 4 seconds needs attention. Above 4 seconds, you are actively losing visitors before they see anything you offer. This isn't a minor technical detail — Google's own ranking system uses load speed as a primary signal, meaning a slow site is simultaneously converting worse and ranking worse. You can check your own load time free with Google's PageSpeed Insights in under a minute.

Sign 2: Your Site Wasn't Really Built for Mobile

More than 60% of all web traffic is now mobile, and in many markets that share is well above 75%. If your layout squishes on a phone, buttons overlap, or text requires pinching to read, you're losing the majority of your visitors before they ever reach your actual offer. Google also indexes the mobile version of your site first for ranking purposes — a poor mobile experience hurts you twice, once with the visitor and once with search rankings.

Sign 3: Your Bounce Rate Is Above 70%, or Your Conversion Rate Is Below 1%

Bounce rate is the percentage of visitors who leave after viewing a single page. A rate consistently above 70%, combined with average time on page under 30 seconds, means most visitors are arriving and leaving almost immediately — a strong signal of a structural problem with layout, calls-to-action, or how information is organized, not something a copy tweak alone typically fixes. A conversion rate below 1% is a similarly reliable indicator of a fundamental usability or messaging problem rather than bad luck with traffic quality. Both numbers are free to check in Google Analytics if you have it installed — and if you don't have it installed, that itself is worth addressing before anything else on this list.

Sign 4: What Brought Someone There Doesn't Match What They Find

High-converting pages maintain what's often called message match: the headline a visitor sees on your page echoes exactly what brought them there, whether that's an ad, a search result, or a social post. When someone clicks expecting one thing and lands on something noticeably different, they leave immediately — regardless of how good the actual offer is. If you're running paid ads, check bounce rate specifically for that traffic source in your analytics; a big gap between ad-traffic bounce rate and organic-traffic bounce rate on the same page is a clear sign of mismatch between what the ad promises and what the landing page delivers.

Sign 5: You Genuinely Don't Know Any of These Numbers

This is the most common sign of all, and the easiest to fix immediately: if you can't answer load time, mobile traffic share, bounce rate, or conversion rate for your own site right now, you're not failing at these metrics — you simply don't have visibility into them yet. That's a different, more fixable problem than any of the four above, and it's the natural starting point before diagnosing anything else.

What to Actually Do About It

Start with the free, self-serve checks: run your homepage through PageSpeed Insights, check Search Console's mobile usability report for flagged issues, and if you don't already have Google Analytics installed, that's the single highest-leverage next step, since everything else on this list depends on being able to see it. Once you have real numbers, the pattern in the data usually points directly at the fix — a specific slow page, a specific device type, a specific traffic source underperforming the rest.

Where to Go From Here

Diagnosing these signs is the first step; fixing what they reveal is its own discipline — see the basics of that process in Website Conversion Rate Optimization Basics, or get the complete picture in the full guide: Website Design and Development for Growing Businesses.
