Plenty of design choices can quietly work against a website: they make it harder to navigate, harder to trust and harder to buy from. Most of them are avoidable. These are the six mistakes we see most often, drawn from two decades of fixing them, and what to do instead.
1. Cluttering the page
The most common mistake is adding design elements simply because they are available. Animated logos, pop-ups, auto-playing video and a complicated navigation bar all compete for attention, and the visitor loses.
The test is simple. If you cannot explain exactly what an element on the page is there to accomplish, it should not be there at all. Start from a clear list of goals for the site, build a simple, solid structure around them, and resist the temptation to keep decorating. A clean page is not an empty page, it is a page where everything earns its place.
2. Designing at the computer first
It sounds odd, but the best place to start a web design is a piece of paper. Site builders make it easy to produce something that looks finished long before it is actually thought through.
List the specific goals the website has to achieve, sketch pages that serve those goals, and only then move to the screen. Working this way exposes redundancies early and keeps the structure honest. It is also, frankly, why experienced designers are worth their fee: not because they can operate the software, but because they get the structure right before anyone touches a computer.
3. Ignoring grids and visual structure
Grids, columns and guidelines predate the web, and they remain the basis of every well-proportioned page. Whether or not the grid is visible, it governs alignment, spacing and rhythm, the things a visitor senses without being able to name.
Skipping the grid because it feels old-fashioned is a young designer’s mistake. Modern layouts can be as expressive as you like and still sit on a disciplined underlying structure. That discipline is what makes a page feel considered rather than assembled.
4. No visual hierarchy
Visual hierarchy means arranging elements in order of importance, so the eye is guided rather than bombarded. Get it wrong and every element fights for attention at once; nothing leads the visitor towards the thing you actually want them to do, and conversions suffer.
Think carefully about why people visit the page, and design the route accordingly: one clear headline, supporting detail in its place, and a call to action that is unmistakably the next step. The best ecommerce sites are a masterclass in this, they stay out of their own way and let the journey to the product carry the visitor along.
5. Overlooking accessibility
Making a website usable by people with a wide range of abilities is both the right thing to do and plain good business: the more people who can use your site, the more people who can become customers.
Build it in from the start rather than retrofitting it later, which is always slower and more expensive. Well-spaced copy, legible type, sensible contrast, alt text on images, captions where they help, and media that plays when the visitor chooses rather than automatically. Designing with accessibility as a priority does not limit creativity; it forces the design to be implemented with purpose.
6. Treating mobile as an afterthought
Mobile browsing accounts for the majority of traffic on the web, which is why mobile-first design has become the standard approach: design for the small screen first, then expand to desktop. Desktop-first thinking is how sites end up slow and cluttered on the device most visitors are actually holding.
Your site has to adapt cleanly across phones, tablets and desktops, from layout to image sizes. If most of your customers will meet your business on a phone, that is the version that deserves the most care.
Then test, analyse and iterate
A design is a hypothesis until real visitors confirm it. Analytics will tell you what is working: watch traffic and its sources, session behaviour and conversion rates. A high bounce rate suggests the page is not earning interest at first glance. Abandoned carts point at a burdensome checkout or surprise costs. Long sessions that never reach the cart often mean the copy is not persuading anyone.
When the data points at the design, have the courage to change it, even if it looks great and took real effort. A/B testing lets you compare versions quickly and decide on evidence rather than taste.
Getting it right the first time
None of these mistakes looks serious on its own, and even large businesses make them. Together they are the difference between a website that wins work and one that quietly loses it. If you would rather get it right the first time, that is exactly what our web design service is for: bespoke, structured, accessible and tested, from first sketch to launch and beyond.
