It can — in either direction, depending on how the redesign is handled.
This is a genuinely important question to ask before any redesign, and the honest answer is: yes, a redesign can affect your Google rankings — for better or worse — depending on how it's done.
The most common cause is changing page URLs without redirecting the old ones, which breaks the trail Google had built up for those pages and can send visitors and search engines to broken links. Removing content that was actually ranking well, restructuring navigation in a way that buries important pages, or introducing new technical problems can all quietly undo months or years of SEO progress.
A redesign done with SEO in mind maps every old URL to its new equivalent with proper redirects, preserves and improves the content that was genuinely working, and treats the technical foundation as part of the design — not an afterthought once the visuals are done. This is exactly the approach we take with Website Redesign projects.
Redesigns are also a natural moment to fix things that were quietly hurting your visibility — slow load times, poor mobile usability, weak page structure, missing meta information. Handled properly, a redesign is more often a net improvement to your Google presence than a threat to it.
Before any redesign begins, ask directly how existing URLs and content will be handled, and whether SEO is being considered during the redesign process itself, not added afterward. That answer tells you a lot about how the project will actually go.
We'll make sure your Google visibility comes out stronger, not weaker.
