The 5 Most Common Website Issues That Kill Conversions

Quick Answer: The five website issues that most consistently kill conversions are: slow page load time, SSL/HTTPS problems showing a "Not Secure" warning, broken links leading to dead ends, a site that doesn't work on mobile, and missing or poorly-written meta descriptions. Most small business websites have at least two or three of these simultaneously.

Most website problems don't announce themselves. They sit quietly, draining your conversion rate one visitor at a time, while you wonder why your traffic isn't turning into customers.

After analyzing thousands of small business websites, we've identified the five issues that show up again and again — and that consistently hurt businesses the most. Here's what they are, how to spot them, and what to do about each one.

Issue #1: Slow Page Load Time

The problem: Your site takes too long to load.

This is the most common issue we find, and the most impactful. Google's data is clear: when page load time goes from 1 second to 3 seconds, bounce rate increases by 32%. From 1 second to 5 seconds? Bounce rate jumps by 90%.

Why it happens:

  • Large, uncompressed images (often the #1 culprit)
  • Too many third-party scripts running on every page (chat widgets, analytics, ad trackers)
  • Slow hosting or a server far from your visitors
  • Page builders that generate heavy, unoptimized code

How to check: Run your site through Google's PageSpeed Insights (free). Your score should be above 90 on mobile for best results. Most small business sites score between 20–50.

What to do:

  1. Compress all images (tools like Squoosh or TinyPNG are free and easy)
  2. Enable browser caching on your server
  3. Minimize the number of third-party scripts you load
  4. Consider upgrading your hosting if you're on the cheapest shared plan

Business impact: According to Portent research, each second of delay reduces conversions by approximately 7%. If you're getting 1,000 visitors a month and converting at 2%, shaving 2 seconds off your load time could mean 14 more leads per month — for free.

Issue #2: SSL/HTTPS Problems

The problem: Your site, or parts of it, aren't properly secured.

SSL (Secure Sockets Layer) is the technology that puts the padlock icon in your browser's address bar and changes your URL from http:// to https://. It encrypts data between your visitor's browser and your server.

If your site doesn't have it — or has it incorrectly configured — modern browsers display a "Not Secure" warning to visitors. For a business trying to earn trust, this is devastating.

Common SSL issues:

  • No SSL certificate at all (still surprisingly common on older sites)
  • Mixed content — the main page has HTTPS but loads some resources (images, scripts) over HTTP
  • Expired SSL certificate — many are set up and then forgotten
  • SSL only on part of the site (e.g., checkout page but not homepage)

How to check: Look at your URL in the browser. Does it say https://? Click the padlock icon — does it say "Certificate is valid"? If you see any warnings, you have an SSL problem.

For a deeper check: SSL Labs offers a free SSL test at ssllabs.com/ssltest/ that will grade your entire SSL configuration.

What to do: Contact your hosting provider. Most now offer free SSL certificates through Let's Encrypt. Installing one usually takes minutes and costs nothing.

Business impact: Studies consistently show that 84% of users will abandon a purchase if data is sent over an insecure connection (source: Baymard Institute). Even if you don't sell online, the "Not Secure" warning makes visitors question whether they can trust you at all.

Issue #3: Broken Links and 404 Errors

The problem: Links on your site lead nowhere.

Every website accumulates broken links over time. It's inevitable. You delete a page, change a URL, a partner's website goes down — every one of those becomes a broken link that sends visitors to a dead end.

Why it matters:

  • Visitors who hit a 404 page typically leave immediately
  • Search engines treat broken links as a sign of poor site maintenance
  • Internal broken links prevent search engines from crawling your full site

How to check: Tools like Screaming Frog (free up to 500 URLs) will crawl your site and list every broken link. Alternatively, Google Search Console shows "Coverage errors" which include 404s that Google has found.

What to do:

  • Fix the link if the page still exists elsewhere
  • Set up 301 redirects from old URLs to current pages
  • Remove links that point to deleted content
  • Add a custom 404 page that helps visitors find what they were looking for

Business impact: If your navigation or footer contains a broken link to a key page (contact, services, pricing), you may be losing a significant percentage of your most interested visitors before they ever reach you.

Issue #4: Not Mobile-Friendly

The problem: Your site doesn't work properly on phones and tablets.

More than 60% of web traffic is now on mobile devices. In many industries — particularly local services — that number is even higher. If your site is hard to navigate on a phone, you're alienating the majority of your visitors.

What "not mobile-friendly" actually looks like:

  • Text that's too small to read without zooming
  • Buttons that are too close together to tap accurately
  • Content that extends off the edge of the screen
  • Pop-ups that can't be closed on mobile
  • Horizontal scrolling where there shouldn't be any

How to check: Open your site on your phone. Then try Google's Mobile-Friendly Test (search.google.com/test/mobile-friendly). Google also flags mobile usability issues in Google Search Console.

What to do: If your site has major mobile issues, a redesign may be necessary. If it's minor, your developer or your website platform's settings can often fix the worst offenders. Prioritize: readable text size, tap-friendly buttons, and no horizontal scrolling.

Business impact: Google uses mobile-first indexing, meaning it judges your site's quality primarily based on the mobile experience. A poor mobile site doesn't just hurt conversions — it actively suppresses your Google rankings.

Issue #5: Missing or Broken Meta Descriptions

The problem: Your search result snippets are wrong, missing, or duplicated.

When your website appears in Google search results, there are two key pieces of text: the title (the blue clickable link) and the meta description (the grey summary underneath). These are your first impression with every potential visitor who finds you through search.

If your meta descriptions are:

  • Missing — Google writes them for you (and often does a poor job)
  • Too long — they get cut off mid-sentence with "..."
  • Duplicated — the same text across multiple pages confuses both visitors and search engines
  • Not compelling — visitors scroll past you to a competitor

How to check: Search for your business or your main keywords. Look at how your pages appear in the results. Does the description make you want to click? Is it cut off?

For a technical view, you can right-click any page and "View Source," then search for <meta name="description".

What to do:

  • Write a unique, compelling meta description for every page
  • Keep them between 120–155 characters
  • Include your main keyword naturally
  • Include a soft CTA: "Learn more," "See our services," "Book a free consultation"

Business impact: A well-written meta description doesn't directly improve your ranking, but it improves your click-through rate — meaning more of the people who see your result actually visit your site. This indirectly signals to Google that your site is relevant and trustworthy.

How to Check All 5 at Once

Checking each of these issues manually is possible but time-consuming. Tools like Google Search Console, PageSpeed Insights, and Screaming Frog each cover parts of the picture — but you'll need to piece together the full view yourself.

Unsnag checks all five of these issues (plus 45 more) in a single 60-second audit and presents the results as a prioritized action list in plain English. No jargon. No deciphering required.

The Bottom Line

Website problems aren't catastrophic failures. They're small leaks — individually minor, collectively significant. A second of delay here, a broken link there, a warning message on your contact page.

Each one loses you a small percentage of the visitors who would have become customers. Added together across a month, a quarter, a year — that's real business impact.

The good news: most of these issues can be fixed quickly once you know about them. The hard part is finding out they exist in the first place.

That's what a proper audit is for.

Frequently Asked Questions

What are the most common reasons a website does not convert visitors into customers? The top five are: slow page load time, SSL/HTTPS problems showing a "Not Secure" warning, broken links leading to dead ends, a site that does not work properly on mobile, and missing or poorly written meta descriptions. Most small business sites have at least two or three of these issues simultaneously.

How do I check if my website is secure? Look at your browser address bar — your URL should start with https:// and show a padlock icon. If it shows http:// or a warning icon, your site lacks a valid SSL certificate. You can run a deeper SSL check at ssllabs.com, or use a free Unsnag audit which checks SSL configuration as part of its security scan.

Why is my website not converting even though I get traffic? High traffic with low conversions usually indicates a friction problem: slow load time causing visitors to leave before the page fully loads, mobile display issues, unclear calls to action, or broken forms. Run a website audit to identify the specific technical barriers, then address them in order of business impact.

How much does slow page speed actually affect conversions? Google's data shows that each additional second of load time reduces conversions by approximately 7%. A site that loads in 5 seconds rather than 1 second could be losing over 25% of potential leads purely to speed. Most small business sites load between 4–8 seconds.

Can I fix these website issues without a developer? Many of them, yes. Image compression, meta descriptions, and SSL certificates can be sorted without technical help. Mobile layout issues and broken link fixes often require a developer, but knowing exactly what is wrong (from an audit) means you can give precise instructions rather than paying for exploratory troubleshooting.
