Lessons from 25 Years of Web Development | John Corner

When you've been building websites for a quarter of a century, you start to see the world in cycles. Tools change, design trends swing back and forth like a pendulum, and best practices get rewritten every few years. But interestingly, the core challenges of good web design haven't really moved much at all.

Looking back on 25 years of development, the landscape is almost unrecognizable compared to where we started. Yet, the destination remains the same. Here are the biggest seismic shifts I've witnessed, and the fundamental truths that haven't budged one inch.

The Internet used to be a brochure - now it's an ecosystem

Cast your mind back to the turn of the millennium. The internet was a quieter, slower, and much simpler place.

In the early 2000s, building a website was essentially just digital typesetting. We built static pages using HTML tables and inline CSS. We optimised for tiny monitors. If you were sophisticated, you might have had a 'Guestbook' or a hit counter at the bottom of the page. Google had only just arrived, Facebook didn't exist, and if you wanted to be social in the UK, you were probably scrolling through Friends Reunited or posting on a message board.

Hosting was just a folder on a server. Security was rarely a concern because there was nothing to steal.

Fast-forward to 2026, and the 'website' has evolved into a living, breathing ecosystem. You aren't just building a few pages anymore; you are managing a complex digital platform. Today, a standard build involves:

• Speed Optimisation: Fighting for every millisecond of load time.
• Accessibility Compliance: Ensuring the web is usable for everyone.
• Security Layers: Managing SSLs, firewalls, and 2FA to fight off automated bots.
• Schema Markup: Writing invisible code so AI search engines understand your content.
• Integrations: Connecting payment gateways, CRMs, booking systems, and analytics.
• Legal Compliance: Navigating GDPR and cookie consent policies.

The job title 'Web Developer' now encompasses security guard, architect, marketer, and lawyer.

Design trends come and go - but good UX is forever

I've seen design trends rise, fall, and sometimes rise again.

We survived the era of Flash intros that took two minutes to load (thankfully dead). We lived through the 'Glossy Web 2.0' phase where every button looked like a shiny glass sweet. We saw Skeuomorphism, where digital notepads looked like real leather. Then came Flat Design, removing all depth, followed by Brutalism, and now the clean, spacious Minimalism that dominates 2026.

However, while the decoration changes, the principles of User Experience (UX) remain stone cold permanent.

Good UX in 2005 is identical to good UX today. Users want:

• Clear navigation (don't make me guess where the menu is).
• Text that is readable (high contrast, good font size).
• A logical layout (headline, image, text, button).
• No nasty surprises (pop-ups, shifting layouts, auto-playing video).

If you chase trends, your site looks dated in two years. If you chase usability, your site works forever.

SEO: From 'tricks' to trust

Search Engine Optimisation used to be the Wild West. Twenty years ago, you could rank a website simply by stuffing the keyword 'Plumber in Teesside' fifty times in white text at the bottom of the page and buying a few links from a directory farm.

It was a game of manipulating the algorithm.

Today, that approach gets you banned. SEO has matured into a sophisticated discipline involving hundreds of ranking signals - from Core Web Vitals (technical speed) to E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness).

Yet, despite the complexity of AI Overviews and voice search, the foundation of SEO is exactly the same as it was in 2000: Google rewards usefulness.

If you write genuine content that answers a user's question, structures it clearly, and serves it on a fast, technically sound website, you will win. The algorithms have just got better at spotting the fakes.

Performance is no longer optional

This is perhaps the single biggest behavioural shift. In the dial-up days, we were conditioned to wait. You would click a link, hear the modem screech, and maybe go make a cup of tea while the images downloaded. Waiting 15 seconds for a page was normal.

Today? We live in the age of the split-second decision.

Data shows that if a mobile site takes longer than three seconds to load, over 50% of users will abandon it immediately. Speed isn't just a technical metric anymore; it's a customer service metric. It impacts your Google rankings, your paid ad costs, and your conversion rates. We have moved from 'just get it working' to 'get it fast, secure, and scalable'.

Clients haven't changed (and that's a good thing)

Amidst all this technological change - the death of Flash, the rise of the iPhone, the birth of AI - the human side of the business has remained reassuringly constant.

Whether it is 1999 or 2026, business owners are still looking for the same four things:

• A website that looks professional and reflects their brand.
• A tool that helps their business make money or save time.
• Someone they can trust to explain the jargon simply.
• A developer who actually picks up the phone when things go wrong.

The tools I use have changed entirely. I've swapped FTP clients for WordPress Block Editors and Notepad for sophisticated software. But the job is still problem-solving.

Clear communication, empathy for the client's budget, and a genuine desire to see local businesses succeed - those are the skills that don't depreciate.

Final thought

A lot has changed in 25 years. The web is faster, prettier, safer, and infinitely more complex. But if you strip away the code and the servers, the heart of web development remains exactly the same:

Make things easier. Make things clearer. Make things better.

Here's to the next 25 years of keeping the web clean, fast, and human.
