Redesigning a website without losing search rankings

The story is familiar: a company relaunches its site, it looks great, and a month later organic traffic has halved. The cause is almost never the design — it is that for a search engine, the old site simply vanished.

What actually breaks rankings

• URLs changed and no redirects were added. Google sees a 404 where a page had been earning traffic for years.
• The text disappeared. The new design is “airy”, and 800 words became 120.
• Meta tags were forgotten. Titles and descriptions were not carried over and the search snippet degraded.
• The site got slower. Heavy motion and unoptimised images.
• The staging site was blocked from indexing and nobody unticked the box after launch. A classic that costs a month.

The sequence that saves traffic

1. Export every current URL. Search Console, the sitemap, any crawler. That is your baseline.
2. Mark what earns traffic. Typically 20% of pages bring 80% of visits — treat those most carefully.
3. Build the old-to-new map. Every old URL must point somewhere meaningful, not to the homepage.
4. Carry over text and meta tags. Shortening is fine; deleting is not.
5. Add the 301 redirects before launch, not after.
6. Check indexing the moment you switch: robots.txt, meta robots, sitemap.

The first two weeks

Some wobble in the first days is normal — the search engine needs time to recrawl. It is a genuine problem if impressions have not returned to their previous level after two weeks.
