Why WordPress is slowing your business down

WordPress is the most popular website platform in the world. It powers roughly 40% of all websites. And for most small businesses building a new site in 2026, it's the wrong choice.

That's not a popular opinion, so let me explain why.

What WordPress was built for

WordPress started in 2003 as a blogging platform. Over two decades, it evolved into a general-purpose CMS by bolting on functionality through plugins and themes. Need e-commerce? Install WooCommerce. Need a contact form? Install Contact Form 7. Need SEO tools? Install Yoast.

This plugin architecture was revolutionary in 2008. In 2026, it's the source of most of the problems small business owners experience with their websites.

The four problems

1. Speed. A typical WordPress site loads 40-80 HTTP requests on a single page load -the theme, 15-30 plugins, Google Fonts, analytics scripts, and whatever else has accumulated over time. Each request adds latency. The result: mobile PageSpeed scores between 20 and 50 for most small business WordPress sites.

A modern site built on Next.js makes 8-15 requests for the same page. The architecture is fundamentally lighter.

2. Security. WordPress is the most-targeted CMS on the internet. Its popularity makes it a magnet for automated attacks. Outdated plugins are the primary attack vector -and most small business sites have at least a few plugins that haven't been updated in months.

This isn't a theoretical risk. WordPress sites get hacked regularly, resulting in spam injections, redirects to malicious sites, and Google penalties that destroy your search rankings.

3. Maintenance burden. WordPress requires ongoing maintenance: core updates, plugin updates, theme updates, PHP version updates, database optimisation, and backup management. Neglect any of these and you get security vulnerabilities, compatibility issues, or a site that stops working entirely.

Most small business owners don't do this maintenance. They set up the site, it works for a year, and then things start breaking.

4. Plugin conflicts. This is the most insidious problem. When you install 15-30 plugins built by different developers with different coding standards, conflicts are inevitable. A plugin update breaks the contact form. A theme update changes the layout. A PHP update makes the gallery plugin crash.

Each conflict requires a developer to diagnose and fix. Over a three-year period, the cumulative cost of plugin conflicts often exceeds what a proper custom build would have cost in the first place.

When WordPress still makes sense

To be fair, WordPress isn't always wrong:

• Large content sites with hundreds of editors who need a familiar interface
• Complex e-commerce where WooCommerce's plugin ecosystem is genuinely useful
• Tight budgets where the priority is "anything online" rather than "something excellent"
• Existing sites that work well and just need content updates

If your site falls into one of these categories, there's no urgent reason to leave WordPress.

When it doesn't

For a typical small business -a service provider with 5-20 pages, no complex e-commerce, and a need for speed, security, and local SEO -WordPress is overkill and underperformance simultaneously. You're paying for the maintenance burden of a complex CMS when all you need is a fast, well-built website that doesn't break.

The alternatives

Next.js (what TillerLabs uses): React-based framework that pre-renders pages as static HTML. Fast by default, secure by architecture, hosted on edge CDNs. Best for: businesses that want top-tier performance and are willing to invest in a proper build.

Astro: Similar to Next.js but ships even less JavaScript by default. Best for: content-heavy sites with minimal interactivity.

Static site generators (Hugo, Eleventy): Maximum simplicity, maximum speed, minimal features. Best for: very simple sites with no dynamic content.

Managed builders (Squarespace, Webflow): template-based, hosted, and maintained for you. Best for: businesses that want to build it themselves and accept the template constraints.

The cost comparison

WordPress isn't free. The hosting, plugins, security, and maintenance add up:

• Hosting: £10-30/month for decent managed WordPress
• Premium plugins: £100-300/year (forms, SEO, security, backups)
• Maintenance: 2-4 hours/month if done properly
• Developer time for conflicts: unpredictable but real

Over three years, a "free" WordPress site easily costs £2,000-4,000 in hosting, plugins, and maintenance -before counting any design or development work.

A TillerLabs build starts at £2,400 (project) or £190/month (subscription). Both include hosting, maintenance, security, and ongoing support. No plugins, no conflicts, no surprise costs.
