Will moving my website to a new platform hurt my Google rankings?

Short answer: it does not have to. Moving platforms, from Squarespace to WordPress, WordPress to Astro, or Wix to anything, does not hurt rankings by itself. What hurts rankings is what usually gets broken along the way.

The Reddit threads that say “I rebuilt my site and my traffic tanked” almost always trace back to one of four things.

1. Old URLs that now go nowhere

Every page Google ranks has an address. If /services/wedding-dj becomes /wedding-dj-services on the new site, and nothing tells Google, the old page now returns a 404 and the ranking it earned goes with it.

The fix is a 301 redirect from every old URL to its closest new equivalent. Not just the homepage, every page that gets traffic or has links pointing to it. That means making a full list of old URLs before the new site is built, not after launch when traffic drops.

2. Content that got “cleaned up”

A redesign is a tempting time to cut words. But the paragraph that looked like clutter might be the one answering the exact question people search for. If a page ranked, keep what made it rank: the topic, the headings, and the substance. Rewrite for clarity, not for brevity.

3. Headings and titles that changed shape

New templates often drop the page title tags, meta descriptions, and heading structure the old site had. A page whose <h1> was “San Diego Wedding DJ” and is now “Welcome” has told Google it is about something else. Carry these over on purpose.

4. Pages that quietly stopped being indexed

A staging site’s “do not index” setting that ships to production, a missing sitemap, or a robots file that blocks everything. These are one-line mistakes that can wipe out a site’s visibility for weeks.

What a careful migration looks like

1. Inventory first. Export every URL, its traffic, and its rankings. Mark the pages that bring in leads.
2. Map every URL to its new home before building anything.
3. Match the content and structure of the pages that rank.
4. Launch with redirects, a fresh sitemap, and indexing checked on day one.
5. Watch Search Console for 4 to 6 weeks. A small dip for a week or two is normal while Google re-crawls. A drop that keeps going means something above was missed, and it is fixable if you catch it early.

A real example

Santa Barbara Wedding DJs held #1 local rankings on a Squarespace site they had outgrown. We moved them to Astro with every old URL mapped and redirected. Every #1 ranking held, and the new site then added a venue directory Squarespace could not realistically support.

Should you move at all?

Move when the current platform is costing you something real: speed, editing pain, features you cannot add, or monthly fees for things you do not use. Do not move just because it is new. If you are weighing it, refresh or rebuild? walks through the decision, and the website rebuilds and migrations page explains how I run them. Moving off WordPress specifically?
