Short answer: WordPress vs Wix comes down to renting versus owning. Wix and Squarespace suit simple sites where design matters more than growth. WordPress suits any business that plans to sell, rank or expand, because you own the site, control the speed and can move it.

If your website has to win work, choose WordPress. If it only has to prove you exist, a builder is a sensible answer, and we say so on calls most weeks. We have delivered over 600 websites across 40 plus countries in 7 plus years, and we still talk people out of a rebuild when the platform they are on is genuinely doing the job.

Aventus Digital builds on WordPress for a living, so treat this as a view from inside the work rather than a neutral survey. Everything below comes from migrations we have actually run, sites we have actually sped up, and quotes we have actually written. Here is the full comparison, with the real numbers on both sides.

WordPress vs Wix: what you are actually choosing between

Wix and Squarespace are closed platforms. You rent the software, the hosting and the editor as one bundle. You cannot see the code that runs your site, you cannot move it to a different host, and if the platform changes its pricing or drops a feature, you take it. Your website lives on their land.

WordPress is open source software you install on hosting you choose. Around 41% of every website on the internet runs on it, and close to 59% of every site built on a recognised content management system, according to W3Techs. Wix sits near 4% and Squarespace near 2%.

That gap is not a popularity contest. It means:

• Thousands of hosts, developers and agencies can work on your site
• You can leave any one of them without leaving your website behind
• Nobody can change your pricing or remove a feature you depend on

So the real question is not which editor feels nicer this afternoon. It is whether you want to rent or own.

Where we come in: every WordPress website design we deliver is built on hosting registered in your own name, with the admin login handed over at launch and a short training session so you can edit pages yourself. Nothing is locked behind our account. If you ever stop working with us, the site stays exactly where it is and any other developer can pick it up. Before you commit to anything, send us your current site and we will build you a free mockup of your homepage on WordPress within 72 hours, so you are comparing two real versions of your own business rather than a demo template.

What does each platform cost in the UK?

Sticker prices are honest enough. Total cost of ownership is where people get caught out, because a subscription is a bill that never stops and a build is a bill that does. These are current UK figures on annual billing, from the Wix and Squarespace pricing pages, set against what you actually get for each.

The pattern is the same every time. A builder is cheaper in year one and more expensive in year five, because the subscription keeps running, the apps stack up, and at the end of it you still do not own the thing you have been paying for. A WordPress build is a cost that finishes.

Where we come in: our tiers are fixed and published rather than quoted after a discovery call. It is £299 for a single conversion focused landing page, £499 for up to 10 pages with full on-page SEO and FAQ schema, and from £1,499 for larger builds with CRM integration and advanced technical SEO. Every tier includes mobile-first design, Core Web Vitals tuning, Search Console and analytics setup, and 30 days of free tweaks after launch, so there is no list of add-ons waiting at the end. You can check the lot on our pricing page and hold it against the five year subscription total above before you speak to anyone. If you want the wider market context first, we break down what other UK agencies charge in our guide to how much a website costs in the UK.

Speed, search and getting found in AI answers

Builders are not automatically slow. Wix in particular has improved a great deal, and a lean Squarespace site on a good template can score respectably.

The difference is what happens when it is not fast enough. On a builder you cannot control server response time, you cannot change how scripts load, you cannot strip out the platform framework, and you cannot choose your host. When the site is slow, your options run out quickly. On WordPress every one of those levers is available.

The targets are not vague:

• Largest Contentful Paint under 2.5 seconds
• Interaction to Next Paint under 200 milliseconds
• Cumulative Layout Shift under 0.1

Those thresholds are measured on real visitor data rather than a lab test, as web.dev sets out. If your current site misses them, the causes are the same on any platform, and we work through all of them in why is my website slow.

On search, all three can rank. Anyone telling you Wix cannot rank on Google is repeating a criticism that stopped being true years ago. Where they differ is depth of control. On WordPress you can edit any title, any schema block, any redirect, any canonical tag, and restructure a URL without asking permission. On a builder you get the options the platform decided to give you. For a brochure site that rarely matters. For a business chasing local searches across several towns, or a shop with hundreds of product URLs, it matters constantly.

AI search has raised the stakes again. Around half of tracked Google queries now return an AI answer, and Google’s own guidance is clear that generative results are built on the same core ranking systems. Clean structure, crawlability and original first hand content are what earn a citation. There are no shortcuts and no special files to add, which we explain in what is GEO? The UK business owner’s guide.

Where we come in: this is exactly what our free SEO and GEO audit is built to answer. We pull your real visitor data for all three Core Web Vitals rather than a single lab score, check whether your schema, headings and canonical tags are actually readable by search engines, and test whether your business is being cited in AI answers for the searches your customers really use. You get the findings back within 48 hours in plain English, whatever platform you are on. If the fixes turn out to be structural rather than cosmetic, that is when a WordPress build starts paying for itself, because on our sites SEO, GEO and AEO are configured during the build rather than sold as an upsell six months later.

When Wix or Squarespace is the right answer

We are not going to pretend there is no case for them.

Choose Wix when speed of launch matters more than anything else. A sole trader can have something live in an afternoon, nothing beats £9 a month on pure outlay, and there is no maintenance to think about. No plugin ever breaks on a Tuesday.

Choose Squarespace when the look is the product. Templates are more considered than almost anything else in the category, which suits photographers, studios, restaurants and creatives. Acuity Scheduling is included on every plan, which quietly removes a separate monthly booking tool for consultants, therapists and trainers.

The honest test is this. If your website is a credibility page rather than a sales channel, and the feature list you need today is the one you will still need in three years, a builder is a sensible choice.

Choose WordPress when any of that stops being true:

• Membership areas, complex bookings or multilingual content, none of which require a platform migration later
• Hundreds of location, service or product pages under your own URL structure
• Selling online, where WooCommerce carries roughly 30% of the ecommerce platform market and takes no cut of your sales, which is why our ecommerce websites are built on it
• A subscription that does not scale with your success

The trade off is real: WordPress needs looking after. Updates, backups and security are genuine work, and a neglected site is the one that gets compromised.

Where we come in: that upkeep is the single reason most people stay on a builder, so we removed it as an objection. Our website maintenance plans start at £49 a month and are handled in house by the same team that builds the sites. We test every plugin, theme and core update for compatibility in a staging environment with a full backup taken first, run weekly off-site backups, monitor uptime and SSL, and send a monthly report you can actually read without a developer to translate it. Plans are rolling, cancel any time with one month’s notice. Put that £49 next to a Wix Core subscription at £16 and you are paying a little more for a site you own outright, maintained by people who know it.

Can you move a website off Wix or Squarespace to WordPress?

Ask this before you commit to anything.

On WordPress you export the database and the files and you move. Content, images, structure and URLs all come with you, so rankings survive.

On Wix or Squarespace there is no meaningful export. Migrating means rebuilding page by page on the new platform, remapping every URL, and absorbing whatever ranking dip follows. The cost is almost always higher than the original build would have been.

Which is why the platform decision is not really a year one decision. It is a year three decision, made in year one.

Where we come in: we run these migrations regularly, and the part that decides whether your traffic survives is not the design work, it is the redirect map. Before we build anything we crawl your existing site, list every live URL, and pair each one with its new equivalent so nothing lands on a 404 the day you switch. A website redesign with us carries your content across, keeps the pages that already earn traffic, rebuilds the ones that do not, and goes live in about two weeks. If you are on a builder and quietly worried about being stuck there, that is the service to look at first.

WordPress vs Wix: which should you choose?

If your website is a credibility page and you are the one editing it, take Wix or Squarespace and spend the saved money elsewhere. If your website has to bring in work, or will need to do something new in the next three years, start on WordPress. Migrating later costs more than starting properly.
