Wix vs WordPress vs Custom Code: The SEO & Performance Showdown

html is the foundation of the website structure and big player on SEO.

You’ve got three main options, each with its own pros and cons for SEO and performance. So, what’s the score?
Choosing between Wix, WordPress, and custom code depends on your goals and resources. Wix is the fastest way to launch a simple brochure site. WordPress offers the best balance of SEO control, scalability, and cost.

Who this guide is for
This guide is for business owners and marketers choosing a platform that won’t bottleneck organic growth, Core Web Vitals, and content scale. If you want something simple and quick, start with Wix. When its about growing traffic and publish content often, go for WordPress. Need an enterprise-level performance or unique features, consider a custom-coded site instead.
Wix: The Simple SEO Starter Kit
Wix makes launching a professional site effortless. It’s an all-in-one, drag-and-drop system with hosting included, so there’s no dev faff. For a local service like Kingston and Richmond Removals, Wix can deliver a clean site with a contact page, services, FAQs, and reviews in a weekend. Even so, as your ambitions grow, its limitations can start to appear.
- Pros
- Speed to launch and minimal setup.
- Templates and built-in features.
- Decent for small, static sites.

- It can bloat as you add features; consequently, load times may rise.
- Best for: Brochure sites, solo operators, and early-stage local businesses.

That’s why a professional chooses WordPress — it’s the perfect engine for growth. With the right stack (a lean theme, premium hosting, and minimal plugins), you can achieve fast Core Web Vitals and, moreover, a content engine built for scale.
- Pros
- Granular control of on-page SEO, schema, information architecture (IA), and internal linking.
- A massive ecosystem of themes, plugins, and headless options.
- It scales from simple blogs to complex sites; likewise, it supports custom workflows.

Custom Code: The Bespoke Powerhouse
Built with HTML/CSS/JS (or a modern framework), a custom site gives you surgical control over markup, assets, caching, and the developer experience. That’s how you squeeze every millisecond for LCP/INP/CLS and craft exactly the schema and IA you want; as a result, the performance ceilings are highest here.
- Pros
- Best-in-class performance potential.
- The cleanest possible markup and asset pipeline.
- Infinite flexibility for bespoke features; similarly, fewer third-party constraints.
- Cons
- The highest cost and lead time.
- Ongoing dev is needed for any changes.
- Requires strong product and process discipline; otherwise, delivery can drift.
- Best for: Complex, high-scale, or feature-rich builds where speed and control are non-negotiable.
Head-to-Head: SEO & Performance Factors
| Factor | Wix | WordPress | Custom Code |
| Technical SEO Control | Basic controls. Limited access to raw code and server config; therefore, deeper tweaks are harder. | Full control via a clean theme + selective plugins. Additionally, headless options expand flexibility. | Total control—semantic HTML, critical CSS, caching, edge functions; consequently, maximum tuneability. |
| Core Web Vitals | Okay for simple pages; however, it can struggle as features pile on. | Excellent with a tuned stack (fast host, lightweight theme, image/CDN strategy, minimal JS). Moreover, modern hosts provide server-level caching. | The highest ceiling—you ship only what’s needed and, therefore, minimise bloat. |
| Information Architecture & Content Scale | Fine for small sites; by contrast, complex silos and taxonomies are limited. | Built for content hubs, taxonomies, custom post types, and internal linking; consequently, scaling content is straightforward. | Anything you can design—but you must build it, which, in turn, increases scope. |
| Speed to Launch & Cost | Fastest and lowest upfront; meanwhile, recurring fees are predictable. | Moderate; needs hosting and setup, yet overall cost remains reasonable. | The longest and priciest; nevertheless, ROI can be superior at scale. |
| Maintenance | Managed for you; therefore, fewer operational worries. | You manage updates and backups (or buy managed WP hosting); additionally, set a maintenance cadence. | Your dev team handles the lot; consequently, plan a budget for ongoing work. |
Final Verdict: Which one should you choose?
- Simple local brochure site (few pages, low change rate): Wix will do the job nicely, especially if you prioritise a quick launch.
- Growth-focused business (content, SEO roadmap, lead gen): WordPress wins on a balance of control, performance, and cost; moreover, it scales gracefully.
- Complex/unique product, high traffic, or enterprise needs: Choose custom code for peak performance and flexibility; ultimately, control trumps convenience.
