The Marketing Manager's Guide to Web Design

We craft purposeful, performance-driven websites that reflect your brand and move your audience to act.

Your website is the most permanent piece of marketing your business has. Every campaign, every ad, every email eventually points back to it. And yet for most businesses, it’s also the thing that gets the least ongoing attention.

This guide covers what marketing managers need to know about web design — from understanding when a website is actually failing, to what good design looks like in practice, to how to know whether a redesign has worked.

What good web design actually means

Good web design is not about aesthetics. It is about whether your website does its job.

That means attracting the right visitors, communicating clearly what you do and who you do it for, making it easy for the right people to take the next step, and performing well enough technically that neither users nor search engines are penalised.

Most websites fail gradually rather than suddenly. A site gets built, launched, and then quietly deprioritised. Design ages, content stales, and the gap between where the website is and where the business is becomes impossible to ignore.

The fix is rarely just a visual refresh. More often it requires rethinking the architecture, clarifying the audience, improving the content, and ensuring the technical foundations are solid. Understanding which problem you actually have is what determines the right solution.

When and how to rebuild your website

What marketing managers typically get wrong

The most common mistake is treating web design as a one-time project rather than an ongoing investment. A website built in 2021 and left untouched will drift — not dramatically, but consistently. User expectations change. Competitors improve. Search algorithms evolve.

The second most common mistake is confusing symptoms with causes. A website that looks outdated is not necessarily failing because of the design. It may be failing because the content no longer reflects the business, because the CMS is so difficult to use that nobody updates it, or because the architecture was built around the old version of the business.

Discovery — properly mapping who the website is for, what it needs to say, and how users actually move through it — is the phase most agencies rush and most clients underestimate. Getting it right before any design work begins saves significant time and budget.

How to measure website success after a redesign

What makes a website perform well

Performance in web design means more than visual quality. A well-designed website:

Converts — every page has a clear purpose and a clear next step. Users are not left to work out what to do.

Loads fast — Google’s Core Web Vitals set the standard. Sites that fail these benchmarks see measurable drops in both rankings and conversion rates.

Works on mobile — over 60% of web traffic is now mobile. A site designed for desktop first is a site designed for the minority.

Can be found — on-page SEO is not an add-on. Semantic structure, clean URLs, properly implemented metadata, and fast load times all affect how well a site ranks.

Can be updated — a CMS that the marketing team cannot use will not be used. If updating a page requires raising a support ticket, the website will stagnate.

Good web design makes all of this possible without requiring technical resource to maintain on a day-to-day basis.

How much does web design cost?

Most web design projects for mid-size businesses start at around £10,000. Scope, complexity, and the level of custom development required determine the final investment. A well-built website typically pays for itself many times over in leads, conversions, and reduced maintenance costs.

How long does a web design project take?

Most projects run between 8 and 16 weeks from kick-off to launch. Discovery and strategy, wireframing, visual design, development, and testing all take time when done properly. Rushing any phase increases the risk of expensive changes later.

How do I know if my website needs redesigning?

The clearest signals are declining organic traffic, falling conversion rates, a CMS your team has stopped using, and a design that no longer reflects where the business is. If your website was built more than three years ago and has not been significantly updated, it is worth an audit.

What is the difference between web design and web development?

Web design covers the visual and UX decisions — layout, typography, colour, user journeys. Web development is the technical build that brings those designs to life in code. A good agency does both, and the two disciplines should work together from the start rather than in sequence.

Do I need SEO as part of my web design project?

Yes. SEO foundations — semantic HTML structure, page speed, clean URLs, metadata, and mobile performance — should be built in from the start, not retrofitted after launch. A website that looks great but cannot be found is not doing its job.
