7 website mistakes that quietly kill your conversions

1. Pages that load slowly

Visitors expect pages to appear almost instantly, especially on mobile. Slow pages lose people before they read a word, and Google uses page experience signals such as Core Web Vitals in its rankings.

Fix it: compress and resize images, remove unused plugins and scripts, use good hosting with caching, and test key pages with Google PageSpeed Insights.

2. A headline that doesn't say what you do

“Excellence in everything we do” tells a visitor nothing. If someone can’t tell within five seconds what you offer, who it’s for and why they should care, they leave.

Fix it: write a headline that names the outcome and the audience, for example “Bookkeeping for restaurants that frees up 10 hours a week”, followed by a one-sentence explanation.

3. No clear call to action

Many pages end without telling visitors what to do next, or offer six competing buttons. Both create hesitation.

Fix it: choose one primary action per page, such as “Book a free consultation”, and repeat it at the top, middle and end. Use a contrasting button colour and action-focused wording.

4. Forms that ask for too much

Every extra form field is another reason to give up. Asking for budget, company size and a detailed brief before the first conversation can halve enquiries.

Fix it: ask only for what you need to reply, usually name, email and a short message. Collect the rest on the first call.

5. A poor mobile experience

For most businesses, the majority of visitors arrive on a phone. Tiny text, buttons that are hard to tap, pop-ups that cover the screen and menus that don’t work are conversion killers.

Fix it: design for mobile first, use large tap targets, make phone numbers clickable, and test every page on a real phone before launch.

6. Missing trust signals

New visitors don’t know you. Without proof, they hesitate to share their details or pay.

Fix it: show real reviews, client logos, case studies, certifications, clear pricing or “from” prices, a physical address or contact details, and a secure checkout. Place them near your calls to action.

7. Confusing navigation

Clever menu labels, too many options and buried contact pages make visitors work too hard.

Fix it: keep the main menu to five to seven clear labels, use plain words like “Services”, “Pricing” and “Contact”, and make sure every page is reachable within two clicks.

Quick wins vs a full redesign

Not every problem needs a new website. Quick wins such as rewriting the headline, shortening the form, adding reviews near buttons and compressing images can often be done in a day and measured within weeks.

A redesign is the better choice when the site is built on an outdated platform, is difficult for your team to update, is not mobile friendly, or when your services and brand have changed so much that patching pages would take longer than rebuilding them. In that case, plan the new site around your best-performing pages and the questions customers ask most, so you keep what works and fix what doesn’t.

Bonus: forgetting what happens after the click

A conversion is not the finish line. If a form submission disappears into an unchecked inbox, or a visitor waits two days for a reply, the lead goes cold. Make sure every enquiry triggers an instant confirmation, a notification to the right person, and a reply within hours. Even a short automated message that says what happens next keeps people engaged.

A 10-minute website conversion checklist

1. Open your home page on your phone. Can you tell what the business does within five seconds?
2. Is there one obvious button telling visitors what to do next?
3. Does the page load quickly on mobile data?
4. Can you tap the phone number to call?
5. Is your contact form five fields or fewer?
6. Are reviews or proof visible near the main call to action?
7. Can you reach your services, pricing and contact pages within two taps?
8. Submit your own form. Did you get a confirmation, and did the right person receive it?

Any “no” on this list is a quick win waiting to be fixed.

How to measure improvements

Before changing anything, record your current numbers in Google Analytics 4: visits to key pages, form submissions, calls and purchases. After each change, compare a few weeks of data against that baseline. For pages with enough traffic, A/B testing lets you show two versions at once and keep the winner. Heatmaps and session recordings show where people click, scroll and give up, which often reveals problems analytics alone can’t.

Where to start

Pick the two or three issues that apply to your most visited pages and fix those first. Then measure enquiries for a few weeks before changing more. If your site needs more than quick fixes, our website design service rebuilds sites around speed, clarity and conversions, and our landing page and CRO service tests improvements on pages that already get traffic.
