An outdated corporate website is worth refreshing — but a redesign done without care can do real damage, wiping out search rankings the business has spent years earning. The good news: it’s entirely avoidable. Here’s how to modernise a corporate site while protecting its hard-won SEO.
Why redesigns hurt SEO
Search engines rank your existing pages based on their URLs, content and the links pointing to them. A redesign often changes all three — new URLs, rewritten or removed content, a different structure — and if those changes aren’t handled properly, the rankings tied to the old pages vanish. Most post-redesign traffic crashes come from this, not from the new design itself.
How to protect your rankings
Preserving SEO through a redesign comes down to a clear checklist. Handle these and your traffic survives the transition.
// PROTECT SEO IN A REDESIGN
✓Keep the same URLs where you can
✓Redirect (301) every URL that changes
✓Preserve content that ranks and gets traffic
✓Map the old structure to the new one
✓Audit and fix before and after launch
✕Changing URLs with no redirects
✕Deleting pages that bring in traffic
✕Cutting content to “clean up” the site
✕Launching with no SEO plan
✕Finding out from a traffic drop later
Preserve what already works
Before redesigning, identify the pages and content that currently rank and bring in traffic or leads — then protect them. Keep their URLs, preserve (or carefully improve) their content, and make sure they survive the move. A redesign is a chance to improve your best pages, not an excuse to quietly delete them in the name of a fresh start.
Redirects are not optional. Every old URL that changes must point (via a 301 redirect) to its new equivalent — this passes the ranking power forward. Skipping redirects is the single most common way redesigns destroy SEO.
Plan SEO in from the start
The businesses that redesign without losing traffic treat SEO as part of the project from day one — auditing the existing site, mapping old URLs to new, planning redirects, and testing before and after launch. Bolting SEO on after a traffic drop is far harder than building it into the plan. If search visibility matters to your business, make it a redesign requirement, not an afterthought — our SEO guides cover the fundamentals worth protecting.
// FREQUENTLY ASKED
Can a website redesign hurt my SEO?
Yes — badly, if handled carelessly. Redesigns often change URLs, content and structure, and without proper redirects and content preservation, the rankings tied to old pages disappear. Most post-redesign traffic crashes come from this, not the new design. It’s avoidable with planning.
How do I redesign a website without losing rankings?
Keep the same URLs where possible, set up 301 redirects for every URL that changes, preserve the content and pages that already rank, map the old structure to the new, and audit before and after launch. Plan SEO into the redesign from the start rather than fixing it after a drop.
Why are redirects important in a redesign?
A 301 redirect points an old URL to its new equivalent and passes the existing ranking power forward. Without redirects, search engines treat changed pages as gone, and the rankings and traffic they held are lost. Skipping redirects is the most common way redesigns destroy SEO.
