The success of any website depends on good web design. Within a few seconds, the look and feel of a site tells visitors whether a business is trustworthy, professional and worth their time. Good design is not decoration, though: it is a set of practical decisions that help people find what they came for and take the next step.
Below are the 10 elements every business website needs. For each one you will find what it is, what good looks like, the most common mistake, and a quick check you can run on your own site today.
1. White Space
White space (or negative space) is the empty area between text, images and other elements. It does not have to be white; it is simply space that is left free so that the content around it can breathe.
What good looks like: generous margins around headings, short paragraphs, and a clear gap between sections, so the eye can move from one idea to the next without effort.
Common mistake: filling every corner with banners, badges and text because the space feels "wasted". A crowded page makes it harder to spot what matters.
Quick check: look at your homepage from arm's length. If you cannot tell what the single most important message or button is, the page needs more space and fewer elements.
2. Colour Combinations
Your colour scheme shapes how visitors feel about your brand before they read a word. Most strong websites use one main brand colour, one or two supporting colours and plenty of neutral tones.
What good looks like: the brand colour is used consistently for buttons and links, so visitors learn what is clickable.
Common mistake: low contrast, such as light grey text on white or white text on a pale background. It looks soft but is hard to read, especially on a phone outdoors.
Quick check: run your main text and button colours through a contrast checker. Body text should meet a contrast ratio of at least 4.5:1, the WCAG AA standard. Our guide to colours to avoid in web design covers the most common problem pairs.
3. Typography
Typography is the choice of fonts, sizes, line spacing and line length. It decides how easy your content is to read and quietly carries your brand's personality.
What good looks like: one or two font families, body text of around 16px or larger on mobile, comfortable line spacing, and lines of roughly 50 to 75 characters on desktop.
Common mistake: using several decorative fonts, or long blocks of small text that tire the reader.
Quick check: read one of your pages on a phone without zooming in. If you have to squint or zoom, increase the font size and line spacing.
4. Content Organisation
Great content only works if people can find it. Content organisation is about the order of sections, the use of headings, and how information is grouped on each page.
What good looks like: the most important information comes first, each section has a clear heading, and related details are grouped so visitors can scan instead of reading every word.
Common mistake: long introductions before getting to the point, or the same information repeated on several pages.
Quick check: read only the headings on a page. They should tell the whole story on their own.
5. Easy-to-Use Navigation
Navigation is the map of your website. Visitors should always know where they are, where they can go next, and how to get back.
What good looks like: a short main menu with clear labels such as "Services", "Our Work" and "Contact", kept in the same place on every page, and a footer with the key links repeated.
Common mistake: clever or vague menu labels, too many menu items, or several different paths to the same page.
Quick check: ask someone who does not know your site to find your contact page or a specific service. If it takes more than a couple of clicks, simplify the menu. We cover this in more depth in 3 principles for better web design.
6. Mobile-First Design
Most website visits now come from phones, and Google uses the mobile version of a page for indexing and ranking. Mobile-first design means planning the phone layout first and then expanding it for larger screens, not squeezing a desktop design onto a small screen.
What good looks like: large tap targets, a menu that is easy to open with one thumb, short forms, and click-to-call and WhatsApp buttons where they make sense.
Common mistake: pop-ups that cover the whole screen, tiny links placed close together, and tables or images that run off the edge of the screen.
Quick check: open your site on your own phone and try to complete your main goal, such as sending an enquiry, using one hand.
7. Speed and Performance
A beautiful website that loads slowly loses visitors before they see it. Google measures real-world loading experience with Core Web Vitals: how quickly the main content appears (Largest Contentful Paint), how fast the page responds to a tap or click (Interaction to Next Paint), and how much the layout jumps around while loading (Cumulative Layout Shift).
What good looks like: compressed images in modern formats such as WebP, only the scripts the page actually needs, and good hosting.
Common mistake: uploading large camera photos directly, and adding plugins, sliders and tracking scripts that each slow the site a little more.
Quick check: test your homepage in Google PageSpeed Insights and focus on the mobile result first.
8. Accessibility and Usability
An accessible website can be used by everyone, including people who rely on screen readers, keyboard navigation or larger text. Accessibility and usability go hand in hand: what helps a visitor with a disability usually helps every visitor.
What good looks like: descriptive alt text on images, form fields with visible labels, buttons that say what they do, and a site that works with a keyboard alone.
Common mistake: using images of text, removing the focus outline from links and buttons, or relying on colour alone to show an error.
Quick check: try moving through your contact form using only the Tab key. You should always be able to see where you are. Our post on the role of UX in modern web design goes deeper into usability.
9. Persuasive Calls to Action
Most business websites exist to get visitors to do something: call, send an enquiry, book a demo or buy. Calls to action (CTAs) are the buttons and links that make that next step obvious.
What good looks like: one main CTA per page, written as an action ("Get a quote", "Book a free consultation"), in a colour that stands out, and repeated after key sections on long pages.
Common mistake: vague buttons such as "Submit" or "Click here", or several competing CTAs of equal weight on the same screen.
Quick check: on each key page, ask: what do we want the visitor to do next, and is that button visible without scrolling on a phone?
10. Visuals and SEO-Friendly Structure
Images, icons and illustrations help visitors understand your product and style at a glance. Behind the scenes, the same pages need a structure that search engines can read: one clear H1 per page, logical headings, descriptive page titles and meta descriptions, and clean URLs.
What good looks like: original photos or illustrations rather than generic stock images, and pages planned with search engine optimization in mind from the start rather than added afterwards.
Common mistake: treating SEO as a separate job after launch, when headings, URLs and page structure are already fixed.
Quick check: search Google for site:yourdomain.com and review the titles and descriptions that appear. Each should clearly describe its page.

FAQs
What are the most important elements of web design?
Clear navigation, a mobile-first layout, fast loading, readable typography with enough contrast, and an obvious call to action matter most, because they decide whether visitors can find what they need and take the next step.
What colour contrast should website text have?
Body text should have a contrast ratio of at least 4.5:1 against its background, and large text at least 3:1. These are the WCAG AA guidelines, and free online contrast checkers will test any pair of colours.
Does web design affect SEO?
Yes. Page speed, mobile usability, heading structure, image alt text and internal links are all part of the design and build, and all of them influence how search engines crawl, understand and rank your pages.
