Important Website Design Factors That Make a Website Work

Explore the website design factors that matter most, from navigation and mobile usability to accessibility, speed, content, trust and conversion.

Your website is often one of the first places someone goes to understand your business. They may arrive from a search, an advertisement, social media, a referral, or because someone simply told them your name. However they get there, the website has an important job to do.

What are the most important website design factors?

Important website design factors include clear navigation, readable and brand-appropriate visual design, mobile usability, accessibility, performance, useful content, trust, and logical paths for visitors to take action. Good design brings those elements together around what visitors need from the website and what the business needs the website to accomplish.

It needs to help them quickly understand where they are, what you do, whether you can help them, and what they should do next.

That is why good website design is about considerably more than making a site look attractive. A website is part brand experience, part communication tool, part sales support, and often part customer service. If it is confusing, outdated, painfully slow, difficult to use on a phone, or filled with information people cannot make sense of, visitors may reasonably assume that experience reflects the business behind it.

A strong website does the opposite. It removes friction and makes it easier for people to connect with the business.

Good Website Design Starts With the Person Using It

It is easy to approach a website from the inside out. The business knows its departments, terminology, history, services, and organizational structure, so these factors naturally influence how the website is organized.

The visitor may not care about any of that yet.

They arrive with a need, a question, a problem, or a goal. Good website design helps them move from that starting point toward the information they need without requiring them to understand the company first.

That human-centered perspective runs through nearly every important website design decision. The question is not simply, “Do we like this?” It is also, “Will the person using this understand it?”

Our Website Design resources explore that relationship between design, usability, branding, and business goals in greater depth.

The original version of this article said visitors should be able to get where they want to go in three seconds and within a few clicks. I would not put a stopwatch or arbitrary click count on good navigation.

What matters is whether the path makes sense.

A visitor should be able to look at the navigation and make a reasonable prediction about where each choice will take them. Labels should use language people understand. Important information should not be buried simply because the company’s internal organizational chart places it elsewhere.

Sometimes getting to the right answer takes one click. Sometimes it reasonably takes several. The goal is not to minimize clicks at any cost; it is to minimize confusion.

Navigation should also work across devices and for people who navigate differently, including visitors using keyboards or assistive technology. Good navigation is not just a tidy design. It is part of making the website usable.

Visual Design Should Support the Brand

A website should look good, but “good” does not mean trendy, elaborate, or filled with visual effects.

The design should fit the business.

Typography, color, imagery, spacing, page structure, and other visual choices create an impression before someone reads every word. Those choices should support the Brand personality and positioning rather than be chosen simply because a particular design style is popular.

The original article suggested that blue creates trust while yellow attracts shoppers. Color is considerably more nuanced than that. Context, culture, contrast, brand history, surrounding colors, and execution all influence how people experience a design.

A financial institution does not become trustworthy because its website is blue, and a retailer does not become exciting because someone added yellow.

The stronger question is whether the visual design communicates the right feeling for this business while making the information easy to see and understand.

Mobile Is Part of Website Design, Not a Separate Version of It

Your customer may encounter your website on a large desktop monitor, a laptop, a tablet, or a phone held in one hand while doing three other things.

The website needs to work across those experiences.

Responsive design is more than shrinking a desktop page to fit a smaller screen. Navigation has to remain usable. Buttons need to be practical to tap. Text needs to be readable. Forms need to work. Images need to behave properly. The most important information still needs to be easy to find.

A mobile visitor should not feel as though they received the compromised version of your website.

This is also why testing matters. A page that looks beautiful while you are building it on a desktop can behave very differently on an actual phone.

Website Accessibility Belongs in the Design Conversation

A well-designed website should work for as many people as reasonably possible.

Accessibility includes considerations such as readable typography, adequate contrast, logical headings, descriptive alternative text for meaningful images, keyboard navigation, clearly labeled forms, understandable buttons, and multimedia that people with different needs and abilities can use.

Many of those practices simply make websites easier for everyone to use.

Accessibility is therefore not something we think should be bolted onto a website after the design is complete. It belongs in the design and development process from the beginning. Our guide to website accessibility and modern web design goes deeper into the practical considerations.

Speed Is a Design Issue, Too

A gorgeous website that makes people wait for it is not delivering a gorgeous experience.

Large images, unnecessary scripts, excessive animation, poorly chosen plugins, third-party services, hosting, and the way the website is built can all affect performance. That means speed cannot be handed entirely to the technical team after every design decision has already been made.

Design and performance have to coexist.

This is one reason we treat website optimization as an ongoing part of maintaining a useful business website. A site changes over time. Content gets added, software changes, integrations accumulate, and what performed beautifully at launch may need attention later.

The Content Is Part of the Design

A website can have beautiful typography, thoughtful spacing, and compelling imagery, and still fail because nobody can figure out what the business is trying to say.

Design and content cannot be separated as neatly as people sometimes try to.

The designer needs to understand the information. The writer needs to understand how people will encounter it. Headlines, supporting copy, images, buttons, forms, testimonials, calls to action, and page structure work together to guide the visitor.

That is also why designing a page around placeholder copy and figuring out the actual message later can create problems. If the content is important enough to be on the page, it should influence how the page is designed.

Calls to Action Should Help People Take the Next Logical Step

The original article recommended putting a call to action on every page. The underlying idea is good: do not leave interested visitors wondering what to do next.

But not every page needs a giant “BUY NOW” or “CONTACT US” button.

The right next step depends on what the visitor is doing.

Someone reading an introductory service page may be ready to schedule a conversation. Someone reading an educational article may need another related resource. A product page may lead naturally to a purchase. A visitor researching a complex service may need a case study, pricing information, FAQ, or another page before they are ready to contact anyone.

A good call to action respects where the visitor is in the decision process and makes the next useful step clear.

Trust Should Be Designed Into the Experience

Visitors are continually looking for clues about whether they should trust a business.

Some clues are obvious: testimonials, reviews, credentials, examples of work, team information, policies, contact information, and clear explanations of products or services.

Others are quieter.

Does the website look maintained? Does the information agree from page to page? Do the links work? Are there typos everywhere? Does the site behave predictably? Can visitors understand who is behind the business? Does the experience feel appropriate for the promise the company is making?

No single trust signal does all the work. People form an impression from the entire experience.

A Website Is Never Really Finished

One of the biggest changes in how we think about websites is that launch day is not the finish line.

A business changes. Customers change. Products and services change. Search behavior changes. Technology changes. The website should be able to change with them.

That does not mean redesigning the entire site every year. It means paying attention to how the website is performing, where visitors encounter friction, which information is no longer accurate, and whether the site still supports the business’s needs.

A useful website is a living business asset rather than a project you finish and forget.

What Makes Good Website Design?

Good website design makes the business easier for people to understand and easier to interact with.

It balances appearance with usability, brand with clarity, creativity with performance, and business goals with what visitors actually need. Navigation, visual design, mobile usability, accessibility, speed, content, calls to action, and trust are not separate boxes to check. They work together to create the experience.

That is ultimately what people respond to—not whether you followed an arbitrary rule about the number of clicks in a menu or chose the supposedly perfect color.

If your website looks fine but you are no longer sure it is actually doing its job, our custom website design team can help you review the entire experience and determine what is worth improving.

Frequently Asked Questions

How important is website navigation?

Navigation helps visitors understand where information lives and how to move through a website. Good navigation uses understandable labels and logical organization rather than relying on an arbitrary rule about how many clicks every page should require.

Does website color affect customer behavior?

Color contributes to a website's overall visual impression, but simple rules such as “blue creates trust” are too broad to guide a brand. Color works alongside typography, imagery, contrast, context, and the rest of the brand identity.

Why is mobile-friendly website design important?

Customers use websites across phones, tablets, laptops, and desktop computers. Responsive design helps navigation, text, forms, images, buttons, and other elements remain usable across those different screen sizes.

How does accessibility affect website design?

Accessibility considers how people with different abilities interact with a website. Readable typography, appropriate contrast, keyboard navigation, logical structure, useful alternative text, and clear forms can improve the experience for many visitors.

Does every webpage need a call to action?

Visitors should have a logical way to continue, but that does not mean every page needs the same sales-focused call to action. The appropriate next step might be contacting the business, buying something, reading related information, viewing work, or continuing research.

Why does website speed matter to design?

Performance affects the experience created by the design. Large files, excessive effects, third-party tools, hosting, and development decisions can make an otherwise attractive website frustrating to use, so speed should be considered throughout design and development.
