Custom WordPress development

WordPress powers 43% of the web for a reason — it's flexible, well-supported, and gets out of the way when set up properly. It's also the platform we see broken most often, because most installs were built by someone who didn't know what they were doing.

• Site loads in 4+ seconds on mobile — Google starts dropping rankings around 3s
• More than 25 active plugins — every plugin is a security risk and performance drain
• Can't update the theme without breaking the site — meaning your developer hard-coded into theme files
• Page builder bloat (Elementor, Divi, WPBakery on every page) producing 5,000-line HTML
• No staging environment — every change is made live, with no rollback
• Shared hosting with 50+ neighbours — slow, insecure, unreliable
• No backups or backups stored on the same server as the site (useless if the server fails)
• Database 500MB+ from old revisions and transients never cleaned

• Google ranking drops — Core Web Vitals (LCP, INP, CLS) are direct ranking factors
• Bounce rate increases 30-50% for every additional second of load time
• Mobile conversion craters — Thai mobile users abandon sites that take over 3 seconds
• Security incidents (see virus-removal) — outdated WordPress is the #1 hacked CMS globally
• Higher hosting costs — bloated sites burn server resources, forcing upgrades
• Frequent downtime — fragile setups break every plugin update

WordPress development pairs with WordPress design, custom plugin development, and e-commerce development when the build needs them.

• Custom theme built on a modern, fast base (no Elementor/Divi bloat) — see our portfolio of past WordPress builds
• Optimised plugin stack — under 15 plugins, all reviewed for performance and security
• Caching + CDN — Cloudflare or LiteSpeed Cache configured properly
• Image optimisation — WebP, lazy loading, properly sized media library
• Managed hosting setup — moved off shared hosting via server configuration to proper managed WordPress
• Staging environment — every change tested before going live
• Daily off-site backups — restorable in under 30 minutes
• Security hardening — same as our virus-removal service, applied proactively

Typical performance lift after rebuild: page load 4.2s → 1.3s, mobile bounce rate -35%, organic traffic +20-40% in 90 days.

This service is one piece of our full digital marketing services lineup. It works best alongside:

• WordPress design — is the visual partner to development
• plugin development — is needed when functionality goes beyond the theme
• e-commerce development — extends WordPress builds with WooCommerce
• virus removal — is the recovery path when a build is compromised
