How to redesign a website without losing search traffic
Traffic loss after a redesign is not bad luck. It is almost always an unplanned URL change, a silently removed page, or a rendering problem that a crawler cannot get past.
Before launch: build the map
Export every indexed URL with its traffic and links. For each one, decide the destination and record it. Pages with traffic and links must have a one-to-one redirect; pages with neither can be retired deliberately.
Check content parity page by page. A redesign that drops the sections which answered a search query will lose that query, however good the new design looks.
During launch: keep it boring
Launch on a Tuesday morning, not a Friday evening. Keep the old site reachable for a short rollback window. Do not change the domain, the URL structure and the design in the same week if you can avoid it.
After launch: watch four things
Index coverage, crawl errors, organic landing pages, and conversions from organic. Compare week over week for a month. A dip that recovers in ten days is normal; one that deepens needs investigation, not patience.
Common questions
- Is a temporary traffic dip after redesign normal?
- A small dip lasting one to two weeks is common as crawlers reprocess the site. A sustained decline beyond a month usually indicates a mapping or content issue.
- Should we keep the old URLs forever?
- Keep redirects for at least a year, ideally permanently. External links and bookmarks do not expire on your schedule.
