WordPress vs Custom Website — Which Should South African Businesses Choose?
WordPress powers 43% of all websites globally — including many professional, high-converting sites. But it also powers the majority of hacked, slow, and underperforming sites. The question is not whether WordPress is good or bad; it's whether it's the right tool for your specific requirements. This comparison gives you a clear, honest framework to make the right decision for your South African business.

WordPress: The Case For
WordPress is mature, well-documented, and has a vast plugin ecosystem. A good developer can build a solid business website on WordPress faster and at lower cost than a custom build. Content is easy to update without technical knowledge, and there are thousands of templates and plugins for standard functionality.
Best for: businesses that need standard functionality quickly, have non-technical staff who will update content regularly, and don't have highly specific performance or customisation requirements.
WordPress: The Case Against
WordPress is the most attacked CMS on the internet. Sites built on outdated plugins or themes are routinely compromised. Performance is heavily dependent on hosting quality and plugin efficiency — many WordPress sites load in 4–8 seconds, significantly impacting SEO and conversion.
Most importantly: WordPress is built for content management, not conversion engineering. Achieving the performance metrics required for competitive organic SEO (Core Web Vitals) on WordPress requires significant additional optimisation work.
Custom (Next.js / React): The Case For
Custom-built websites on modern frameworks like Next.js consistently outperform WordPress on every technical metric: page load speed, Core Web Vitals scores, security (no plugin attack surface), SEO performance, and long-term scalability.
IoT Advisory builds all systems on Next.js, deployed on Vercel's global edge network. The result is websites that load in under 1 second, score 90–100 on Google Lighthouse, and have no dependency on third-party plugins that can break or be compromised.
Cost Comparison
WordPress build: R18,000–R45,000. Custom Next.js build: R28,000–R85,000. The custom build costs more upfront but eliminates ongoing plugin licensing fees (R200–R2,000/month for premium plugins), reduces security vulnerability exposure, and delivers better performance ROI through higher conversion rates and search rankings.

Open the CalculatorFrequently Asked Questions
Is WordPress still a good choice in 2026?
Yes — for specific use cases. WordPress remains excellent for content-heavy blogs, news sites, and businesses that need non-technical editors to manage content. For high-performance lead generation systems, e-commerce, or anything requiring optimal Core Web Vitals, custom frameworks outperform it significantly.
Can a WordPress site rank on Google?
Yes. WordPress sites can and do rank well on Google. The key variables are content quality, technical SEO implementation, and page speed. A well-optimised WordPress site can compete; a poorly-built one (common with cheap template installs) will consistently underperform.
