You’ve outgrown your Wix or Squarespace site, but one fear keeps you on it: if we rebuild, will we lose our Google rankings? It’s a fair worry — those rankings took years to earn, and a botched migration really can tank them. Here’s the honest reassurance: done right, a migration preserves your rankings, and more often than not it improves them. The risk is real, but it’s entirely manageable. It comes down to a handful of technical steps done carefully. This guide walks through what actually protects your SEO in a move — and the specific mistakes that cause the horror stories.
Why the fear is valid — and why it’s manageable
Google ranks individual pages, and it ties everything it knows about a page — its authority, its history, its keywords — to that page’s exact URL. When you rebuild, URLs and page structure can change. If Google goes looking for a page it has ranked for years and finds nothing there, that ranking is at risk. That’s the real mechanism behind “we lost our rankings in a redesign.”
The good news: that mechanism is completely predictable, which means it’s completely preventable. Every page that matters keeps its value as long as you tell Google where it moved. Migrations don’t tank rankings — careless migrations do.
The one step that protects your rankings: 301 redirects
If you take one thing from this guide, take this. The single most important part of a safe migration is mapping every existing URL and setting up 301 redirects for any URL that changes.
A 301 redirect is a permanent “this page has moved here” instruction. When someone — or Google — requests the old URL, the server automatically sends them to the new one. Crucially, a 301 also passes the old page’s accumulated SEO value to the new address. In plain terms: it forwards your rankings to the new URL. Miss the redirect and Google hits a dead end (a 404), the old page’s authority evaporates, and the ranking goes with it.
So the migration process is:
- Map every existing URL. Crawl the current site and list every page Google knows about — nothing gets missed.
- Keep the same URL structure wherever possible. The safest change is no change. If
/charters/can stay/charters/, keep it. Fewer changed URLs means fewer things that can go wrong. - 301 every URL that does change to its exact new home — one old page to the one equivalent new page, not all of them dumped onto the homepage.
This is THE step. Get it right and you’ve protected the large majority of your ranking risk.
Preserve your on-page SEO — don’t lose content in the rebuild
Redirects protect the address; the page itself still has to carry its SEO. A surprising amount of ranking loss comes not from redirects but from quietly dropping content during a redesign because it “looked cluttered.” Google ranked those words. Carry them over. For each page, preserve:
- Page titles (the title tag) and meta descriptions — match them to the old site, then improve from there.
- Headings — your H1s and H2s, keeping the keyword structure Google already rewards.
- Body content — don’t slim a 600-word service page down to two sentences for the sake of a cleaner look. That text is why the page ranks.
- Image alt text — easy to forget, and it feeds both image search and accessibility. Marine sites are photo-heavy; that’s a lot of alt text worth keeping.
A rebuild is a great moment to strengthen this material. Just make it additive — improve on what ranks, don’t quietly delete it.
The technical cutover, step by step
The mechanics matter as much as the content. A safe cutover looks like this:
- Keep your domain. Your domain carries most of your accumulated authority, so keep the same one and simply point it at the new host. You don’t lose history by changing platforms — only by changing (or fumbling) the domain.
- Build the whole site before you cut over. The new site should be complete, tested, and staged privately before it goes live. Cutover is a switch you flip once everything’s ready — not a construction site the public watches you assemble.
- Verify in Google Search Console and submit the new sitemap. Confirm the migrated site in Search Console, submit its XML sitemap, and Google recrawls the new structure quickly instead of stumbling onto it. Then watch the Coverage and Performance reports through the transition.
- Keep HTTPS. The new site must load over
https://from minute one, with the padlock intact. Dropping to an insecure connection is both a ranking and a trust problem.
One bonus you’ll likely see on the other side: speed. A properly built WordPress site is usually faster than the same site on a DIY builder, and Core Web Vitals (Google’s page-experience speed metrics) tend to improve after a migration off a bloated builder theme — a small ranking tailwind. If speed is your main frustration today, our guide on why marine websites are slow and how to fix it explains what’s usually dragging a builder site down.
What actually causes ranking loss — the “don’t do this” checklist
Every migration disaster traces back to the same short list. Avoid these and you avoid the horror story:
- Broken or missing redirects. The number-one cause. Old URLs that 404 instead of 301-ing to their new home.
- Changed URLs with no redirect. Restructuring your slugs is fine — as long as every old URL 301s to its new one.
- Dropped pages and content. Deleting pages that were ranking, or gutting the text on the ones you keep.
- Lazy redirects. Pointing every old URL at the homepage instead of its true equivalent. Google treats that as a soft 404 and the value doesn’t transfer.
- Long downtime. A site that’s offline or half-broken for days while you finish building it live. Build first, cut over once.
- Losing HTTPS. Going live without a valid SSL certificate.
Why leave Wix or Squarespace at all?
Briefly, because it’s worth being sure the move is right before you make it. Marine businesses usually outgrow the builders for three reasons: ownership (on WordPress you own the code and data and can host anywhere; on a closed builder you’re renting), custom features and integrations (boat inventory feeds, real booking systems, deep local SEO — the things builders simply can’t do), and performance ceilings (you can only tune speed so far inside someone else’s platform). If you’re still weighing the platforms themselves, our WordPress vs Wix vs Squarespace guide for marine businesses lays out where each one genuinely wins — including when staying put is the smarter call.
Realistic expectations
Let’s be straight about what a well-run migration looks like week to week. Even done perfectly, you may see a small ranking wobble for a week or two while Google recrawls and re-indexes the new structure. That’s normal — it’s Google catching up, not damage. A clean migration recovers within a couple of weeks and, thanks to better speed and stronger on-page work, usually climbs past where it started. Anyone promising zero movement or an instant jump to #1 is selling you something; the honest picture is a brief dip followed by recovery and gains.
Send us your current site
If you’re nervous about moving, that’s the healthy instinct — it means you’ll do it carefully. The safest migrations start with a full audit of what you have before anything changes.
