Where the "redesign kills traffic" fear comes from — and when it's justified
Stories of "we refreshed the site and traffic vanished" are everywhere, and they're real. But it's not the new design that kills — it's a careless move: ranking pages vanished or moved to new addresses without redirects; the copy people found you by got "cleaned up for beauty". Google doesn't punish a new look — it simply loses what it knew about you.
Five rules of a safe redesign
- Keep URLs where you can. A page's old address is its accumulated history. There's no reason to change /services/implants "for style".
- If addresses change — a 301 map. Every old URL → its matching new one. Not wholesale to the home page — page by page.
- Preserve the meaning of working pages. Check Search Console for the pages bringing traffic, and don't rewrite their H1s and topics beyond recognition.
- Don't lose speed. A new design with heavy animation can be slower than the old one — and speed is a ranking factor.
- Monitor for 30 days. Search Console daily for the first month: indexing errors and sagging pages show immediately, while they're still easy to recover.
Redesign, migration, or a new site?
A redesign is a new look on the same platform. A migration is a move to another platform (say, WordPress to custom code) with content and addresses preserved. In practice they usually happen together: the platform aged, and so did the design. That's fine — the rules are the same, the redirect map is just bigger.
Case: Efedra — the redesign after which traffic grew
The clinic moved off an old site with a full change of design and structure. We preserved the working meaning, built the redirect map, and monitored Search Console after launch. Six months on: 1,460 visits versus 340 — traffic never dipped for a single week. Full breakdown — in the case study.
The checklist before you hit "Publish"
- All old URLs exported (Search Console → Pages)
- The 301 map written and tested page by page
- H1s and topics of breadwinner pages preserved
- New version's speed ≥ the old one's (PageSpeed before/after)
- Sitemap updated, Search Console notified
- Calendar: 30 days of daily monitoring booked
