Wix vs Custom Website: What's Actually Better?

I'm going to be straight with you: Wix isn't always the wrong choice. But for most established local businesses, a custom website will perform better, cost less over time, and give you a lot more control.

Here's the honest comparison.

Speed

This is the biggest practical difference, and it matters more than most people realise.

Wix sites carry a lot of bloat. The platform loads its own scripts, tracking code, and interface tools on every page, whether you need them or not. The result is slow load times, and slow load times hurt your Google ranking.

A custom-built site only loads what it needs. No platform overhead. With a lightweight hand-coded site, hitting a Lighthouse performance score of 90+ is achievable. Most Wix sites sit in the 50s or 60s.

When someone in Lewisham searches for your service on their phone, a page that loads in one second beats a page that takes four. Every time.

SEO

Wix has improved its SEO tools in recent years. You can add title tags, meta descriptions, and alt text. That's fine.

But the deeper SEO stuff is where it falls short. Wix generates messy code that's harder for Google to crawl. Structured data (the schema markup that helps Google understand exactly what your business is and where you are) is limited and difficult to implement properly. URL structures can be awkward.

A custom site gives you full control over the code. You can add exact LocalBusiness schema, geo coordinates, full service area listings, all the signals that help a local business rank in the right place for the right searches.

Design Freedom

Wix gives you a lot of options on the surface. Hundreds of templates, drag-and-drop editing, lots of colour and font choices.

In practice, the templates all start to look the same. The layouts are constrained by the platform. You're always working within someone else's system, and it shows.

A custom design starts from your business. Your brand, your customers, your goals. Nothing is off the shelf.

For a local business in East Dulwich or Crystal Palace, that difference shows in how professional the site feels when someone lands on it.

Monthly Fees and Ownership

Wix charges you monthly, indefinitely. The business plan, which you need for a proper custom domain and no Wix ads, sits around £15-20 a month. Over three years that's £540-720 spent on something you can never fully own or export.

If Wix changes their pricing, or you want to move to a different platform, you're starting from scratch. You don't own the code.

With a custom site, you pay once for the build. Hosting is separate and cheap, usually £5-10 a month. And you own everything. The code, the design, the content. You can move hosts. You can hand it to a different developer. It's yours.

When Wix Makes Sense

If you're testing a business idea and genuinely don't know if it'll take off, Wix lets you get something online fast without spending much. That's a legitimate use case.

If you're just starting out and need a placeholder while you save up for a proper site, Wix is fine for that.

But if you're an established business in SE London and your website is how people find you and decide to contact you, you deserve something better than a template.

The Bottom Line

Wix is fine for getting started. A custom website is better for growing.

If you're past the "testing the idea" stage, the investment in a custom site pays back through better rankings, better conversions, and no ongoing platform fees eating into your margins every month.
