Custom WordPress website development
WordPress powers 43.5% of all websites worldwide in 2026 (W3Techs). Our agency builds custom WordPress websites: brochure, corporate and e-commerce. Every project is developed without generic templates, with code optimized for performance and organic search from day one.

Why choose WordPress for your business website?
WordPress is the most widely used CMS in the world, and for good reasons. Open source, extensible and backed by a community of 60,000 active developers, it offers unmatched flexibility for any type of web project. According to BuiltWith (2025), 68% of sites running an identifiable CMS run on WordPress.
At NEXUS SYNERGY, we harness that power to build genuinely custom websites. No themes bought on ThemeForest, no page builders bloating the code. Every line is written to serve your business goals precisely, with load times under 1.5 seconds.
- 43.5% of websites worldwide run on WordPress (W3Techs, 2026)
- Custom theme developed from scratch (no generic template)
- Lighthouse Performance score above 95/100
- Intuitive CMS: your teams are autonomous in under 1 hour
- GDPR compliance and native WCAG 2.2 accessibility
How do we guarantee the performance of your WordPress site?
Web performance is not optional: Google has used Core Web Vitals as a ranking factor since 2021. According to a Portent study (2024), a site that loads in 1 second converts 3 times better than one that takes 5 seconds.
Our technical stack relies on a lightweight WordPress theme built in native PHP, conditional asset loading, and a performance-first architecture from the very first line of code. The result: sites that consistently score above 95 on Lighthouse.
- Lightweight theme in native PHP (no Elementor, Divi or WPBakery)
- Optimized Core Web Vitals: LCP < 1.5s, INP < 100ms, CLS < 0.1
- Smart lazy loading and automated WebP/AVIF images
- Server-side caching (Redis/Varnish) + global CDN
- Auditable code and full technical documentation

How does a well-built WordPress site improve your rankings?
A properly developed WordPress site is a ranking machine. According to Ahrefs (2025), 90.63% of web pages get zero organic traffic from Google. The difference comes down to the technical layer: semantic HTML structure, Schema.org markup, smart internal linking and silo-based content architecture.
We integrate technical SEO during the development phase, not after. Every page is designed to target a specific query, with a content plan aligned with your prospects' search intent.
- Semantic silo architecture to strengthen topical authority
- Schema.org markup (Organization, LocalBusiness, Product, FAQ, Article)
- Automated, contextual internal linking
- Dynamic XML sitemap and optimized robots.txt
- Safe SEO migration (301 redirects, PageRank preservation)

WordPress development questions
- How much does a custom WordPress website cost?▾
The budget depends on the complexity of the project. A custom brochure site starts around $3,000, a corporate website runs between $5,000 and $15,000, and a WooCommerce store starts at $8,000. Every quote is tailored after a free discovery phase where we analyze your needs.
- How long does it take to build a WordPress website?▾
Allow 4 to 6 weeks for a brochure site, 6 to 10 weeks for a corporate website, and 8 to 14 weeks for a full e-commerce store. These timelines include design, development, testing and training your team on the CMS.
- Why choose a custom theme over a premium theme?▾
Premium themes load dozens of unnecessary CSS and JS files, which drags down performance. A custom theme contains only the code you actually need: the result is a faster, more secure site that ranks better in Google. According to our internal benchmark, a custom theme is on average 3 to 5 times lighter.
- Will I be able to edit my website myself?▾
Absolutely. We configure WordPress with custom fields (ACF Pro) and tailor-made Gutenberg blocks so your teams can edit content without touching a line of code. We include a 1-hour training session and a personalized user guide.
- Will my WordPress site be optimized for mobile?▾
Yes, all our websites are built mobile-first. In 2026, more than 63% of global web traffic comes from mobile devices (Statista). We test every page on more than 15 different screen resolutions and validate mobile Core Web Vitals before launch.
