Common Website Errors | What’s Costing You Customers?

Written by Maggie McTavish | Mar 4, 2026 1:00:00 PM

Picture this: A homeowner gets referred to a roofing contractor in Niagara. They type their domain name into their phone's web browser. The site loads slowly, the text is tiny, there’s no clear phone number, and the contact form feels clunky. They hit back and call the next company in the search results. No angry email. No bad review. Just a silent lost opportunity.

This is how underperforming websites quietly cost Niagara businesses real revenue every single week. Our guide will break down the most common issues pushing customers away - and provide a practical checklist business owners can use to spot potential problems.

1. Slow Website Speed on Desktop & Mobile

A few extra seconds to load may not seem significant - until customers start clicking away.

Website speed directly impacts:

  • User experience
  • Search engine rankings
  • Website traffic
  • Bounce rates

Why It Happens

  • Large file sizes: Oversized images or videos that slow down page load times.
  • Outdated Content Management System (CMS): Older website software that can’t keep up with modern performance demands.
  • Web server issues: Your website runs on a hosting server. If that hosting is cheap, overloaded, or poorly configured, performance suffers.
  • Poor web development practices: Heavy code, unnecessary plugins, or outdated design that drags the site down.

When page speed drops, customers don’t wait - they leave. And those exits send signals to Google that can negatively impact your SEO performance.

2. No Trust Signals Visible at the Top of the Home Page

Within 3 seconds, a website visitor decides whether you’re credible.

If your home page doesn’t clearly show:

  • What you do
  • Who you serve
  • Real reviews
  • Proof of certifications

You create doubt.

Missing trust signals are among the most common website errors business owners make. If someone sees a generic layout with no local photos, no testimonials, and no recognizable branding, it won’t matter how good your work is.

3. Missing or Weak Calls to Action (CTAs)

You’d be surprised how many sites we audit that have:

  • No visible contact forms
  • No “request a quote” button
  • No clear email address or phone number
  • No click-to-call option for mobile devices

That’s a huge missed opportunity. Every website page should guide visitors toward the next step. Without strong CTAs, you’re relying on them to figure it out - and they won’t.

4. Technical Errors You Can’t See

We often find:

  • Broken links: Links that don’t go anywhere, and instead, an error page loads.
  • Page error messages (404): Pages that can’t be found.
  • Bad requests (400): Mistakes that stop pages from loading.
  • Internal server errors: Your website’s hosting may be unstable or experiencing frequent server downtime, causing pages to fail.
  • Missing or incorrect metadata: Titles and descriptions that show up in search results, or image alt text, are missing or incorrect.
  • Duplicate content: Identical content on multiple pages makes it hard for search engines to determine which page to rank.

These technical errors quietly sabotage your SEO and damage your search rankings - often without you even knowing.

Google Search Console and other website monitoring tools can flag these errors, but many website owners don't know how to check.

5. Website Design Mistakes That Impact Your Brand

Your website is the digital face of your business. Many people don’t realize that a well-designed website matters, relying heavily on social media promotion instead. But if your site looks outdated, cluttered, or confusing:

  • It lowers perceived value
  • It reduces conversions
  • It increases bounce rates
  • It weakens SEO

Design errors to look out for include:

  • Too much text overwhelming the page
  • Missing page titles and subtitles
  • Excessive pop-ups interrupting users
  • Cluttered layouts with no clear focus
  • Poor mobile responsiveness
  • Hard-to-read fonts or low contrast colours

Website Best Practices Checklist

Ask yourself:

  • Does my site load in under 3 seconds on desktop and mobile?
  • Is my phone number or contact information visible instantly?
  • Do I have strong CTAs on every website page?
  • Have I noticed any broken links or web page errors?
  • Is my website content bulky or distracting?
  • Do my pages show proper titles and descriptions in search results?
  • Is my web hosting provider reliable?
  • Does my site build immediate user trust?

If you’re unsure about any of these, there’s a good chance your website is quietly costing you.
