What migrations break (so you can prevent it)
Orange County businesses redesign for good reasons—speed, mobile UX, new offers—but SEO equity lives in URLs, content depth, internal links, and trust signals. Migrations fail when teams treat SEO as a post-launch ticket.
- 404s on legacy money pages
- Title/H1 dilution (“Home” and thin service stubs)
- Lost FAQ/Article schema or duplicated junk schema
- CWV regressions from heavy page builders
- Broken phone click tracking and form events in GA4
- GBP website field still pointing to dead paths
Pre-migration checklist
- Export top URLs from Google Search Console (pages + queries)
- Export analytics landing pages by conversions (not just sessions)
- Crawl the live site (all indexable URLs, status codes, canonicals)
- Inventory backlinks to key URLs (at least head terms / money pages)
- Document GBP landing URLs and citation URLs
- Freeze non-essential URL inventiveness—“pretty” slugs are optional; parity is not
- Staging robots: block indexing on staging; never accidentally ship noindex on prod
Redirect mapping (the heart of the project)
Build a spreadsheet: old path → new path → status (301). Rules of thumb:
- One hop when possible (avoid chains)
- Money pages map to the closest intent match—not everything to homepage
- Preserve PDF/guide URLs that earn links, or 301 to HTML equivalents
- Test samples with curl/browser before DNS cutover
Content parity: If an old page was 3,000 words of useful guidance, do not replace it with a three-sentence brochure. Migrations are a common moment thinness creeps in. Keep depth or intentionally consolidate with user-first redirects.
Launch day checklist
DNS / SSL / HTTPS
Force HTTPS; fix mixed content immediately.

30-day monitoring
| Week | Watch | Act if… |
|---|---|---|
| 1 | 404 spikes, redirect failures | Fix map gaps same day |
| 2 | Coverage / excluded reasons | noindex, canonical conflicts |
| 3–4 | Query + landing page dips | Restore content depth; fix internal links |

Local SEO / GBP specifics
Update Google Business Profile website URLs the same day you launch. If Maps traffic lands on 404s, you train Google that your landing experience is poor—expensive in competitive OC categories.
Verify NAP consistency post-launch, and confirm location pages still resolve for every pin (multi-location guide). If SOCWD is building your redesign, migration SEO is part of how we ship—not an add-on surprise. Start at contact or see when/why/how to redesign.
Redirect QA worksheet (run before DNS cutover)
- Export top 100 landing pages by conversions from analytics + top 100 by clicks from Search Console.
- Map each to a 200 OK destination with a single 301 hop.
- Spot-check 20 random blog URLs and all service URLs linked from GBP.
- Confirm trailing-slash and http→https rules do not create chains.
- Load the new contact form on mobile LTE; submit a test lead tagged “migration QA.”
- Click-to-call on iOS Safari and Android Chrome.
If content depth drops on money URLs during redesign (“we’ll add copy later”), treat that as a ranking risk equal to a bad redirect. Parity first; polish second.
FAQ
Will a website redesign hurt my SEO?
It can—if URLs change without 301s, content is thinned, speed regresses, or tracking breaks. A planned migration with parity and monitoring often preserves and then improves performance.
How long do rankings take to stabilize after migration?
Expect turbulence for days to weeks while Google recrawls. Major URL changes can take longer. Watch Search Console coverage and query reports weekly for the first month.
Should I change domains and redesign at the same time?
Avoid stacking risk. Migrate hosting/design on the same domain first when possible. Domain changes need extra DNS, Search Console, and redirect rigor.
What is the #1 migration mistake you see in Orange County?
Launching a pretty site that 404s old service URLs that had backlinks and Map Pack landing traffic—with no redirect map and GA4 events dead.
