Static website vs dynamic website: what's the difference and which is right for you?

When you’re having a new website built or thinking about refreshing your current one, you’ll inevitably encounter a fundamental technical choice: static or dynamic. It sounds technical, but it has direct consequences for things that genuinely matter to you as a business owner: how fast your site loads, how secure it is, how much maintenance it needs and how well it ranks in Google.

This article explains the difference clearly — without jargon where possible.

What is a dynamic website?

With a dynamic website, every page is generated at the moment of a visit by a server. The most familiar example is WordPress, but Magento, Drupal and most custom webshops work the same way.

The process looks like this:

1. A visitor types your URL into the browser
2. The browser sends an HTTP request to your server
3. The server executes PHP code
4. PHP queries the MySQL database (your content, menus, settings)
5. PHP assembles the HTML based on that data
6. The server sends the HTML back to the browser
7. The browser renders the page

That sounds fast, but at every step there’s waiting time. The database query takes a moment. The PHP execution takes a moment. The network latency takes a moment. On a good server with low traffic it’s acceptable, but during peak load or on cheap hosting the visitor notices.

Advantages of dynamic websites:

• Real-time content (shop inventory, login functionality, personalised content)
• Familiar CMS interface for non-technical users (WordPress dashboard)
• Large plugin ecosystems (WordPress has 60,000+ plugins)

Disadvantages of dynamic websites:

• Slower than static (server must do compute work on every visit)
• Security risks via outdated plugins or themes
• Higher maintenance (updates, patches, backups)
• Higher hosting costs (PHP server is required)

What is a static website?

With a static website, all pages are created in advance — as plain HTML files. There’s no server doing compute work at the moment of a visit. The files are ready on a CDN, a server geographically close to the visitor.

The process on a visit:

1. A visitor types your URL into the browser
2. The browser sends an HTTP request to the nearest CDN point
3. The CDN sends the ready-made HTML back directly
4. The browser renders the page

No PHP, no database, no intermediate processing. Just files read directly from disk and sent.

Advantages of static websites:

• Extremely fast (no server-side processing)
• Secure (no database, no server-side code = smaller attack surface)
• Almost no maintenance (no plugins, no updates)
• Low hosting costs (static files are cheap to host)
• High PageSpeed scores

Disadvantages of static websites:

• Less suited for real-time content (inventory management, login functionality)
• Content updates require a new build (though that only takes 1–2 minutes)
• More technical expertise needed during initial setup

The effect on PageSpeed and SEO

This is where it becomes genuinely relevant for most business owners: Google ranks fast websites higher.

Google uses Core Web Vitals as a ranking signal. The three key metrics are:

• LCP (Largest Contentful Paint) — how fast does the largest element on the page load?
• INP (Interaction to Next Paint) — how quickly does the page respond to interaction?
• CLS (Cumulative Layout Shift) — do elements jump around while loading?

Static websites score structurally better on all three metrics, simply because there’s less overhead. An Astro site on Vercel achieves scores of 90–100 on PageSpeed Insights without any extra tuning. A standard WordPress site typically falls between 40 and 70 — and even lower with heavy plugins or cheap hosting.

That PageSpeed difference translates into two things: higher rankings in Google and fewer visitors bouncing because the page loads too slowly. Google research shows that the probability of a bounce increases by 32% when load time goes from 1 to 3 seconds.

When should you choose static?

A static website is the right choice when:

• Your website primarily provides information (business site, portfolio, blog)
• You don’t need complex login functionality or personalised content
• You want the lowest possible maintenance costs
• You prioritise high page speed and strong SEO performance
• You’re not adding dozens of new products or pages every week

In practice: business sites, landing pages, portfolios, blogs and informational sites — all perfectly suited to static.

When should you choose dynamic?

A dynamic website is the better choice when:

• You’re building a webshop with inventory management, login functionality and a checkout
• Your site needs to show personalised content based on user behaviour
• You have multiple users adding dozens of pages or products daily
• You need complex search and filter functionality

For a Shopify webshop you choose Shopify (dynamic, but optimised). For a news platform with thousands of editors you choose WordPress or a real-time CMS.

The best of both worlds: static + headless CMS

The most common question I hear from business owners: “But I want to be able to update my own texts. Isn’t that impossible with a static site?”

It isn’t — thanks to a headless CMS. Platforms like Sanity, Contentful or Netlify CMS give you a user-friendly dashboard for updating texts, images and pages. When you press save, the CMS automatically triggers a new build of the static site. Within one to two minutes your changes are live.

The result: the user-friendliness of a dynamic CMS, combined with the speed and security of static HTML.

Our approach

At Web Builders we choose Astro as our static framework and Vercel as our hosting platform. That combination delivers:

• PageSpeed 95–100 out of the box
• Hosting for €0–20 per month
• Zero maintenance after delivery
• Direct integration with a headless CMS when the client wants it

For clients who need a webshop, we build in Shopify — also a platform that supports static or hybrid rendering for content pages.
