💡 TL;DR : A website's success depends first and foremost on its appearance, but it is judged on how it performs in practice. Five principles work together: the clarity (understand the offer in a matter of seconds), the trust (concrete evidence, not just a pretty façade), theexperience (a route that follows the visitor's intention), the performance (it works on all screens) and theaction (an obvious next step). Research shows that visitors form their first impression of a website in as little as 50 milliseconds — but that impression only holds true if everything that follows confirms it.
A website first attracts visitors with its appearance: bold typography, high-quality images and a harmonious layout. This first impression is formed almost instantly and sets the tone for what follows.
Then the visitor begins to explore. They seek to understand what you have to offer, to assess your credibility and to find the information they need. The quality of the website is then revealed through its usability — not simply through its appearance.
The 5 principles of an effective website, at a glance
Principle | What it offers | A question to ask yourself | Missing signal |
|---|---|---|---|
Clarity | Visitors can understand what's on offer in a matter of seconds | What should he expect when he arrives here? | He bounces back without realising what you're doing |
Trust | Specific reasons to choose us | What evidence can I provide? | He reads everything but doesn't get in touch with you |
Experience | A journey that stays true to its purpose | Which pages, and in what order? | He gets lost or gives up along the way |
Performance | The website works on all screens | Has it been tested on mobile devices, including forms? | Unreadable buttons, forms that freeze |
Action | An obvious next step | What should he do after reading this page? | He leaves without taking any action, even though he's interested |
Qualitative view: the order of importance depends on your audience and your sector.
1. Clarity: making your value clear
Clarity means enabling a visitor to understand what you're offering, to whom, and why it's relevant to them — in a matter of seconds, without having to search for it.
A clear promise, well-explained services and relevant examples enable visitors to understand what your business does. The design plays a direct part in creating this clarity: the size of the headings, the spacing between elements and the order in which information is presented guide the reader's attention.
A practical example: A homepage that replaces 'We support your digital transformation' with 'We design websites that turn your visitors into customers in six weeks' immediately answers the visitor's three questions, without them having to click anywhere else to find out more.
Focus on clarity when:
Visitors are emailing to ask about things that have already been explained on the website
The bounce rate on the home page is high
Is your team finding it difficult to summarise the offer in a single sentence?
Please note: Clarity does not mean simplicity at any cost. A website can be rich in content whilst remaining clear, provided that the visual hierarchy guides the reader.
2. Trust: giving people reasons to choose you
Trust is built on concrete evidence, not just a polished presentation: detailed projects, genuine testimonials, a clearly explained approach, and consistent details.
Their choice depends on the questions your audience has. Does a prospective client want to understand your approach? Show them the steps and decisions behind a project. Do they want to know if you can meet their needs? Showcase relevant projects and explain your contribution.
A practical example: Rather than simply a client logo taken out of context, a case study stating 'Redesign of website X: conversion rate rose from 1.2 per cent to 3.8 per cent in four months' provides verifiable evidence, not just a claim.
Build confidence when:
Visitors read several pages but don't get in touch with you
You do not have any visible testimonials or client case studies
Contact details or legal notices are difficult to find
Please note: The quality of the design, transparency of information, comprehensive and up-to-date content, and links to the rest of the web are among the most consistent factors contributing to a website's credibility — factors that were first identified in the late 1990s and have since been confirmed, despite changing visual trends.
3. The experience: creating a nature trail
User experience is about ensuring the site's structure aligns with the visitor's actual intent — which is not always what your internal organisational chart suggests.
For a service-based business, a customer journey may begin with discovering a service offering, continue with a project that illustrates it, and then lead to the customer making contact. Each stage provides the information needed for the next.
A practical example: On a service page, adding 'See a similar project →' at the bottom of the page, before the generic 'Contact us' link, allows visitors to proceed at their own pace rather than forcing them into a premature conversion.
Focus on the experience when:
Visitors spend a lot of time browsing without reaching a key page
You're adding pages without thinking about where they fit into the user journey
Two very different visitor profiles use the same path
Please note: It is worth thinking about the structure right from the start — which pages are useful, what each one should contain, and how to link them — rather than once the content has already been written.
4. Performance: paying close attention to what happens during use
Performance means ensuring that the website actually works: text that is readable on mobile devices, buttons that are easy to select, and clear forms with error messages that are easy to understand.
Adapting to different screens requires a reassessment of content priorities. On a mobile phone, essential information must remain accessible and interactions must be user-friendly.
A practical example: a call-to-action button measuring at least 24×24 pixels — this is the minimum size specified by the Web Content Accessibility Guidelines (WCAG) to ensure it can be selected with a finger without accidental clicks.
Focus on performance when:
The mobile conversion rate is significantly lower than that for desktop
Forms lead to users abandoning the process without a clear error message
The website has not been tested on a range of devices recently
Please note: A reliable user experience builds on the care taken with the design — a beautiful website that is slow or buggy on mobile devices fails to make a good first impression.
5. Action: channelling interest
A call to action is about giving the visitor a clear next step that's tailored to their intention — not a generic button that's the same on every page.
The wording on the button matters too. 'Discuss your project' and 'Discover our projects' indicate two different steps. Visitors need to know what to expect.
A practical example: A project page that offers 'View another similar project' rather than 'Contact us' allows the visitor to explore before committing — the suggested action is appropriate to the stage they are at, rather than the immediate commercial objective.
Practise the move when:
A page is receiving traffic but generating few clicks on the CTA
The same generic button appears on every page
You don't know what action each page is supposed to trigger
Please note: A project page can link to a related service rather than automatically redirecting to the contact page — the suggested action must be appropriate to the visitor's stage in the journey.
How to evaluate your website: 5 questions to ask yourself
Does a visitor understand what's on offer in under 10 seconds? If not, it's a question of clarity rather than design.
What concrete evidence are you presenting? If the answer is 'none', trust is based solely on appearances.
Does the visitor journey follow the visitor's intentions, or your internal organisational chart? The two do not always coincide.
Has the website been tested on mobile devices recently? Not just supposed to work — actually tested.
Does every page offer an action? If a page ends without asking the visitor for anything, it's a missed opportunity.
The pitfall: judging a website solely on its appearance
Comparing websites solely on the basis of their appearance can be misleading, as a polished design says nothing about what happens once the visitor starts looking for information. A beautiful but confusing website loses as many visitors as a dated but clear website can convert.
Compare what each website supports to the visitor, not just how it looks in a screenshot.
Where we are now
At B2S, we design every website as a digital experience that serves a specific purpose. These five principles guide our approach: the text, the pages, the visual elements and the website's functionality are all considered as a whole, rather than treated in isolation.
Our aim: to create a carefully crafted experience, from the very first impression right through to the next decision. A design that captivates. An experience that guides. A website with a clear purpose.
If your website doesn't yet tick all five of these boxes, this is the sort of redesign we carry out with Framer: bespoke, high-performing and conversion-ready. Find out more →

FAQ
How can I tell if my website lacks clarity?
If visitors email you with questions that have already been answered on your website, or if your bounce rate on the home page is high, this is often a problem of clarity rather than a lack of content.
What trust signals should be displayed on a B2B website?
It depends on what your audience wants to know: detailed projects outlining your specific contribution, genuine testimonials, or a transparent explanation of how you work.
Do we need to rebuild the whole website to improve the user experience?
Not necessarily. Starting by mapping out the existing user journeys (which pages, in what order) often reveals the need for targeted adjustments rather than a complete overhaul.
How can you test a website's performance without using complex tools?
Browsing through the pages on multiple devices, submitting the forms yourself, checking the links and seeing where an interaction fails is enough to detect the majority of problems.
Is good design enough to convert visitors?
No. An attractive design creates a favourable first impression, but conversion depends on a combination of the five principles — in particular, the clarity of the offer and a clear call to action presented at the right moment.
