What Makes a Good Website? 10 Principles for a Homepage That Converts
A good website lets the right visitor understand what you offer, trust you and take the next step, quickly and on any device. Most guides on what makes a good website stop at adjectives: clean, modern, intuitive. They are hard to disagree with and impossible to test. The ten principles below each come with a way to check them, so you can judge your own site rather than simply agree with the list.
1It says what you do, and for whom, on the first screen
Visitors decide within seconds whether they are in the right place. The top of your homepage needs three things: a headline that states what you do and who it is for, a line of proof or difference, and one primary call to action.
Show your homepage to someone outside the business for five seconds, then close it and ask what you do. If they cannot say it in a sentence, the headline is doing the wrong job.
2It is built around what visitors come to do
A good website is organised around visitors' top tasks, not around the company's org chart. Navigation labels should use the words customers use, and the most common tasks should be reachable in one or two clicks.
List the ten most common reasons people visit, using your analytics landing pages, Search Console queries and the questions your sales or support team hears. Then check how many clicks each one takes from the homepage.
3It is fast on a mid-range phone
Speed is judged on the devices and connections your visitors actually use, not on the office Wi-Fi. Google's Core Web Vitals give clear thresholds for a "good" experience, measured on real users at the 75th percentile.
| Metric | What it measures | Good |
|---|---|---|
| Largest Contentful Paint (LCP) | How quickly the main content appears | 2.5 seconds or less |
| Interaction to Next Paint (INP) | How quickly the page responds to taps and clicks | 200 milliseconds or less |
| Cumulative Layout Shift (CLS) | How much the layout jumps while loading | 0.1 or less |
PageSpeed Insights for individual pages, and the Core Web Vitals report in Search Console for the whole site.
4It works for everyone
Accessibility is still where most sites fall down. WebAIM's annual analysis of the top one million home pages keeps finding detectable accessibility failures on the vast majority of them, around 95% in its recent reports. In the UK, the Equality Act 2010 applies to services offered online, and the practical target for most organisations is WCAG 2.2 at level AA.
Run an automated checker, then do what the tools cannot: navigate the site with a keyboard only, zoom to 200%, and check colour contrast on buttons and text over images. Automated tools catch only part of the issues.
5It proves what it claims
Every claim on a website ("experts", "trusted", "results-driven") is worth less than one piece of evidence. Trust comes from case studies with specific outcomes, named clients shown with permission, reviews, accreditations, real people behind the business, and clear contact details.
For each claim on your homepage, find the evidence that supports it on the same page. Where there is none, add proof or remove the claim. Place proof close to your calls to action, where hesitation is highest.
6Every page has one clear next step
A page with five equal buttons has none. Each page should have one primary action that matches where the visitor is in their decision: a contact or quote request on a service page, a product added to basket on a product page, a related guide or sign-up on an article.
For each key template, name the primary action in one phrase. Then check forms: every field you remove makes completion easier, so keep only what you need at that stage.
7Its content answers real questions
Good content covers what visitors need to decide, in their language, one topic per page. Google's guidance on helpful content points the same way: pages written for people first, by people who know the subject. Content that answers questions clearly, section by section, is also what AI search tools are most likely to quote, as we explain in our comparison of GEO and SEO.
Compare your service pages with the questions prospects ask in sales calls. Every recurring question should have a clear answer somewhere on the site.
8Search engines can find and understand it
A beautiful site that search engines cannot read is invisible. The basics: pages that can be indexed, an XML sitemap, clean URLs, one clear title and H1 per page, internal links that connect related pages, and no important page left without links pointing to it. Good SEO is built into templates, not added afterwards.
Crawl the site with an SEO crawler and check the Pages report in Search Console for pages that are excluded from the index and should not be.
9It is secure and legally sound
HTTPS on every page, an up-to-date CMS and plugins, and regular backups are the minimum. In the UK, non-essential cookies need consent under PECR and UK GDPR, a privacy policy must explain how data is used, and limited companies must show their registered name, number and office address on their website.
Check that no tracking fires before consent, that forms explain how data will be used, and that your company details appear in the footer or legal pages.
10It is measured and maintained
A website is never finished. Good sites have analytics with conversions properly defined, Search Console connected, a named owner for content, and a regular review of what is working.
Can you say, from your data, which three pages generated the most enquiries or sales last quarter? If not, measurement is the first fix.
Homepage design principles: what each section should do
The homepage is where these principles meet. Homepage design examples vary widely, but the strongest share a similar layout, where each section has one job.
- HeroSay what you do, for whom, with one primary actionCommon mistake: a slogan that could belong to any company
- Proof barShow evidence early: clients, reviews, accreditationsCommon mistake: logos without permission or context
- Services or productsRoute each visitor to the right pageCommon mistake: too many options at equal weight
- How it worksRemove uncertainty about the processCommon mistake: generic steps with no detail
- Case studiesProve results with specificsCommon mistake: stories with no measurable outcome
- Content or insightsShow expertise and support SEOCommon mistake: old posts that signal an inactive site
- FAQAnswer objections before they stop the visitorCommon mistake: questions nobody actually asks
- Final call to actionGive a clear next step to those ready to actCommon mistake: a vague "get in touch" with no reason to do it
Common mistakes that hold a good-looking website back
- Rotating sliders in the hero. Most visitors only ever see the first slide, and the message you rely on may be on the third.
- Stock photography instead of your own people and work. It signals that there is nothing real to show.
- Navigation labels in internal language. Visitors look for "Pricing" or "Services", not the name of an internal department or product line.
- Contact details hidden behind a form. Some visitors want to call or email directly, and making them hunt costs enquiries.
- Everything gated. Asking for an email before any useful content is shown rarely builds trust with someone who does not know you yet.
- Pages written by and for the company. Mission statements and history belong on an About page, not in the place where visitors decide whether you can help them.
B2B website or ecommerce: what changes
| B2B or service website | Ecommerce website | |
|---|---|---|
| Primary action | Enquiry, call or demo request | Add to basket and checkout |
| Key proof | Case studies, expertise, clients | Reviews, delivery and returns, secure payment |
| Navigation | By problem, service or sector | By category, need and filters |
| Pages that make or break it | Service pages and case studies | Category pages, product pages and checkout |
| Speed matters most on | Landing pages from ads and search | Category, product and checkout pages |
The principles are the same, but the priorities are not. An ecommerce site lives or dies on its product and checkout templates. A service business lives on how well its pages explain and prove its expertise.
What makes a great website, not just a good one
The ten principles make a website good: clear, fast, trustworthy and easy to use. What makes a great website is what competitors cannot copy easily. A distinctive brand that is recognisable at a glance. Original content, data or tools that people come back for and other sites link to. Proof specific to your business rather than generic reassurance. A good website removes reasons not to choose you. A great one gives reasons to choose you over everyone else.
Score your website out of 20
Give each of the ten principles a score: 0 if it is missing, 1 if it is partly in place, 2 if it passes the test.
A strong site. Focus on testing and incremental gains.
Solid foundations with clear gaps. Fix the lowest scores first, starting with those closest to conversion.
The problems are structural. A redesign is likely to deliver more than a series of patches.
If a redesign is on the table, plan it with search in mind from the start, so the new site keeps the visibility the old one earned. Our web design agency team works from exactly these principles, and you can see how they apply in our work. Before you move anything, read our SEO migration checklist.
