Most businesses know when a website looks outdated. Far fewer realise when a website looks fine but is quietly costing them leads and revenue every single day. These are not dramatic failures — they are small, compounding mistakes that accumulate into a meaningful business problem. Here are the ten most common I see when auditing sites.
The 10 mistakes
1. No clear call to action above the fold
The first screen of your homepage should immediately answer one question: what should I do? If a visitor has to scroll to find a phone number, a booking link, or a contact button, many will not. Place your primary CTA visibly in the first viewport of every page.
2. Slow load time
Google research shows that 53% of mobile visitors abandon pages that take longer than 3 seconds to load. A one-second delay reduces conversions by 7%. If your site scores below 80 on Google PageSpeed Insights for mobile, you are losing visitors before they ever see your content. How a slow website costs you customers covers this in depth.
3. Not mobile-optimised
A "responsive" site is not automatically mobile-optimised. Responsive means it fits the screen. Mobile-optimised means it is designed for fingers first — large tap targets, readable text without zooming, no horizontal scrolling, fast load times on mobile networks. Over 60% of your visitors are on smartphones.
4. Cluttered layout with no visual hierarchy
When everything competes for attention, nothing gets it. A homepage crammed with eight sections, multiple competing headlines, and no clear visual priority leaves visitors confused. Effective design uses white space, size contrast, and weight to guide the eye.
5. Poor colour contrast and unreadable text
Grey text on a white background. Small font sizes. Low-contrast buttons. These are accessibility failures that also hurt conversions. WCAG requires a contrast ratio of 4.5:1 for normal text. Many sites fall far short of that standard.
6. No trust signals
Visitors arrive with scepticism. Without social proof — client testimonials, project photos, case studies, recognisable client logos, or a visible address and phone number — there is nothing to overcome that scepticism. Trust signals should appear early on the page.
7. Outdated design that signals neglect
A website that looks like it was built in 2014 tells visitors that your business has not invested in itself. Design trends signal relevance. This does not mean chasing every trend — it means a clean, modern aesthetic that communicates professionalism.
8. Broken forms, links, or features
A contact form that never delivers emails, a booking button that goes nowhere, or internal links that return 404 errors — these are embarrassing failures that actively destroy trust. Regularly verify every form submission and every link.
9. Missing basic SEO
No meta descriptions. Missing alt text on images. Duplicate title tags. A heading hierarchy that jumps from H1 to H4. These are not advanced SEO problems — they are foundations that should be in place from day one.
10. No analytics or conversion tracking
Without analytics you are flying blind. You do not know which pages generate leads, where visitors drop off, or whether your homepage converts at 0.5% or 5%. Setting up analytics and tracking contact form submissions takes hours and immediately gives you the data needed to improve.
A website that looks good and makes none of these mistakes is rare. Most have three or four. If yours has six or more, fixing them is the highest-ROI improvement you can make to your marketing this year.
Quick self-audit
Go to your homepage right now: can you see a clear CTA without scrolling? Does it load in under 3 seconds on your phone? Is there at least one testimonial on the page? If you answered no to any of these, you have found your starting point.
