The average business website converts between 1% and 3% of its visitors. That means for every 100 people who find your site, 97 or more leave without taking action. For most businesses, this represents an enormous amount of lost revenue — and most of the problem comes down to a handful of avoidable mistakes.

After auditing hundreds of business websites, we see the same conversion killers appearing again and again. Here are the five most common, and what to do about each one.

MISTAKE 01
Your headline talks about you, not your client
The most common website headline mistake: "Welcome to [Company Name]" or "We are a leading provider of [service]." Your visitor does not care about you — they care about what you can do for them. Your headline should immediately communicate the specific outcome you deliver for the specific person you serve. Replace "We provide accounting services" with "Stop guessing about your finances — clarity and control, guaranteed."
MISTAKE 02
Too many calls to action — or none at all
Both extremes kill conversions. A page with no clear next step leaves visitors with no obvious path forward. A page with five different CTAs — "Call us", "Email us", "Book a demo", "Download our guide", "Follow us on Instagram" — creates decision paralysis. Each page should have one primary action you want visitors to take. Everything else is secondary. Make that primary action obvious, repeated, and compelling.
MISTAKE 03
Slow page load speed
Research consistently shows that for every additional second of load time, conversion rates drop by approximately 7%. A site that loads in 5 seconds will convert significantly fewer visitors than one that loads in 1.5 seconds — even if the design and content are identical. Page speed is also a direct Google ranking factor. Run your site through Google PageSpeed Insights and address the issues it identifies.
MISTAKE 04
No social proof above the fold
Visitors make a decision about whether to trust your business within seconds of landing on your page. If the first thing they see is your branding and a headline, with no evidence that real people have used and benefited from your services, you are asking them to trust you without giving them any reason to. Place your strongest social proof — a client quote, a result, a recognisable client logo — as close to the top of the page as possible.
MISTAKE 05
Your contact form asks for too much information
Every additional field in a contact form reduces completion rates. The longer and more invasive your form, the fewer enquiries you will receive. For most businesses, a first-contact form should ask for three things: name, email, and what they need help with. You can collect more detailed information once a conversation has started. Reduce your form to the minimum viable fields and watch your enquiry rate increase.

The Common Thread

Look at these five mistakes and you will notice a common theme: they all make the visitor's life harder. A confusing headline, too many options, a slow site, no trust signals, a demanding form — each of these places unnecessary friction between your potential client and taking action.

Conversion rate optimisation is fundamentally about reducing friction. Every element of your website should make it easier for the right person to take the next step — not harder.

The good news is that fixing these issues does not require a complete website rebuild. In most cases, targeted changes to your headline, CTA, and form can meaningfully improve your conversion rate within days of implementation.
