The decision to leave Wix or Squarespace usually comes from outgrowing them. You want real performance, control over how the site works, custom functionality the platform will not allow, or simply an end to bumping into limits. And then the fear arrives, the one that stops people from ever making the move: will I lose my Google rankings?
It is a fair fear. A botched migration can suppress traffic for months. But a well-planned one preserves rankings, and frequently improves them, because the destination is faster and cleaner than what you left. The difference between those two outcomes is not luck. It is the plan.
Why rankings are at risk during a migration
Your rankings are attached to URLs. Google has indexed your about page, your service pages, and your posts, and each one carries authority it has accumulated over time. A migration changes two things that can sever those connections. The URL structure changes, because Wix and Squarespace impose their own patterns and WordPress uses its own. And the underlying HTML, content, and internal links are rebuilt from scratch.
If Google follows an old URL and lands on a 404, the authority attached to it evaporates. If the content or structure quietly changes along the way, rankings wobble while Google reassesses. The entire job of a migration is to carry every one of those signals across intact.
The redirect map is everything
The single most important artifact in any migration is a complete redirect map: every old URL pointed at its new equivalent with a 301 redirect. A 301 is a permanent redirect, and it passes the accumulated authority from the old URL to the new one. A 302 or a 404 does not.
Building it is methodical work:
- Inventory every existing URL. Pull them from the platform’s sitemap, Search Console, and a full crawl, so nothing is missed.
- Map each one to its new address on the WordPress site.
- Implement the 301s so they are live the moment the new site launches.
- Test before and after launch, confirming every old URL resolves to the right destination.
Leaving URLs out of that map is the number-one cause of traffic loss after a migration. It is tedious, and it is not optional.
Preserve the on-page signals
Redirects carry authority across; the on-page signals carry relevance. Both have to survive:
- Titles and meta descriptions. Bring them across deliberately, rather than letting a new theme regenerate them into something different.
- Headings and body content. Keep the actual text. Rankings are tied to content, and rewriting everything during the migration changes too many variables to diagnose if something slips.
- Image alt text and filenames. Easily lost in an export and re-import, and worth checking explicitly.
- Structured data. Re-implement any schema the old site had, and take the opportunity to improve it.
- Internal links. Update them to the new URLs so the site stands on its own internal link structure rather than leaning entirely on redirects.
The WordPress upside
Here is the part the fear obscures: a migration done right does not merely preserve your SEO, it removes the ceilings the old platform placed on it. The reasons you are moving are the same things that help you rank. Full control over URLs and crawlability. Faster pages and better Core Web Vitals. Precise schema instead of a generic approximation. The migration is the moment you get to fix everything the old platform could not.
The launch sequence
Order of operations matters on launch day:
- Build and QA on staging, away from the live site.
- Finalize and test the redirect map before anything goes live.
- Launch with redirects active from the first minute.
- Submit the new sitemap in Search Console to prompt a re-crawl.
- Monitor coverage and rankings closely for the first few weeks, and fix any 404s the moment they surface.
A small, temporary fluctuation while Google re-crawls and re-indexes is normal. A sustained drop is a signal that something in the map or the on-page work was missed, and it is fixable if you are watching for it.
The honest expectation
Do not expect literally zero movement. Expect a brief settling period, then a recovery to where you were, and often past it, because the new platform serves Google better than the old one did. The risk is real, but it is entirely manageable with a deliberate plan. That, rather than luck, is what separates a migration that costs you traffic from one that finally lets the site perform. Getting the 301 redirects right is where it is won or lost.
