Choosing a Website Redesign Company Without Losing Your Traffic

The design is rarely the risky part. The risky part is that a redesign usually arrives with new URLs, a new content system and rewritten copy attached, and Google lists site moves alongside algorithmic updates and technical faults as one of the six causes of a search traffic drop. Every page currently earning visits is an asset with an address, and a redesign is the moment those addresses change. Ask a prospective web development partner how they intend to protect them.

This is not an argument against redesigning. It is an argument for knowing which change caused which outcome, which is only possible if the changes are separable.

Google's site-move documentation states it plainly: "Change only one thing at a time. Plan your changes to your site one after the other, not everything at the same time." A single release that swaps the visual design, the URL structure and the CMS produces one outcome and no way to attribute it. Sequenced releases produce four readable results.

Before anything moves, Google's guidance is to build a mapping from current URLs to their new form, starting with the important ones and drawing on sitemaps, server logs and analytics. Embedded images and videos count — they have URLs too, and they are the ones teams forget. Redirects are then served from the server as permanent ones, 301 or 308, and for small to medium sites Google recommends moving every URL at once rather than a section at a time.

Google treats a 301 as a strong signal that the target should be processed, drops previously indexed URLs that return 404 or 410, and follows up to ten redirect hops by default — which is what makes chained redirects from two successive redesigns a real problem. The failure mode to watch for is the soft 404: a page whose content reads as an error while the server still answers 200. Retired pages that quietly render an empty template are the usual cause, and they consume crawl budget that should be going to real content.

After the move, Google's own checklist is Search Console: indexed counts falling on the old sitemap and rising on the new one, crawl errors in the page indexing report, and impressions in the performance report. Expect movement while this settles — Google says a medium-sized site takes a few weeks for most pages, and that ranking fluctuation during a migration is normal.

To judge whether the new site is better, use field thresholds rather than a lab score: LCP under 2.5 seconds, INP of 200ms or less, CLS of 0.1 or less, each measured at the 75th percentile of real page loads. That is also the honest way to judge the SEO side of a redesign. See our work, or tell us what you are planning.
