We hear "WordPress is bad for SEO" constantly — and it's mostly wrong. The real problem isn't WordPress itself, it's how most WordPress sites get built.
Why WordPress Gets a Bad Reputation
The typical WordPress site is assembled from a purchased theme, a page builder plugin like Elementor or Divi, and a dozen more plugins for forms, SEO, caching, and sliders. Each of these adds its own CSS and JavaScript, most of which loads on every page whether it's needed or not. The result is a site carrying 3-5MB of unnecessary code — which is exactly why WordPress sites often score poorly on Core Web Vitals.
What a Well-Built WordPress Site Looks Like
None of this is inherent to WordPress as a platform. A custom-built WordPress theme — built with native Gutenberg blocks or Advanced Custom Fields instead of a page builder — produces clean, minimal HTML with none of that overhead. We regularly ship WordPress sites scoring 95-100 on Google PageSpeed as part of our Custom WordPress Development service, which is on par with custom-coded alternatives.
When Custom Code Actually Makes Sense
Custom-coded platforms (React, Next.js) earn their complexity when you have needs a CMS genuinely can't serve well:
- Proprietary interactive functionality — calculators, dashboards, user portals
- Programmatic SEO at scale — generating thousands of dynamically templated pages
- Extremely high traffic requiring specific caching or edge-rendering architecture
- SaaS products with authenticated user experiences
For a typical business website — services, portfolio, blog, contact — none of these apply, and custom development adds cost and maintenance overhead without a proportional SEO benefit.
The Real Decision Framework
Don't choose based on "WordPress vs custom code" as an SEO question — choose based on what your business actually needs functionally, then build whichever platform correctly. A cleanly-built WordPress site will outrank a bloated custom React site every time, and vice versa. The platform matters far less than the build quality.
If you're currently on a slow WordPress site, the fix usually isn't a full platform migration — it's removing your page builder and rebuilding with clean, custom blocks. That alone typically fixes 80% of the performance problem at a fraction of the cost of a full custom rebuild. Not sure which route fits your project?
