Website Redesign SEO Checklist: Protect Your Existing Pages

Inventory the website before designing its replacement

A redesign can improve usability while accidentally removing pages that customers already find through search. Start with a list of existing URLs from a crawl, your sitemap and Search Console. Record each page’s purpose, search clicks where available, useful external links and whether it generates enquiries.

The inventory does not need to be complicated. A spreadsheet with old URL, action, new URL, content owner and test result is enough for a small site. Keep a backup of the current website and its configuration so the team can recover if launch checks uncover a serious problem.

Give every old URL an intentional outcome

Keep existing URLs where they still make sense. When a page moves, map it to the most relevant replacement and use an appropriate permanent server-side redirect, normally 301 or 308. Link directly to the final URL within the new site rather than relying on redirects for navigation.

Do not redirect every retired URL to the homepage. A visitor following a specific service link should reach an equivalent service page. When content has no suitable replacement, a genuine 404 or 410 response can be appropriate. Document the decision rather than disguising the missing page with an unrelated destination.

• Preserve valuable service explanations and customer questions.
• Update internal links to final destinations.
• Avoid redirect loops and unnecessary chains.
• Check images and downloadable resources that have their own URLs.
• Retain control of the old domain when changing domains so redirects can continue.

Separate preview restrictions from launch settings

A preview site may need protection so unfinished pages are not publicly indexed. Before launch, check how that protection works and who will remove it from the production site. A noindex directive left on important pages can prevent them appearing in search even when the design looks finished.

Check each important page has a sensible title, a description, a canonical pointing to the intended live URL and readable page content. Include the final indexable URLs in the sitemap. Google needs to be able to crawl a page to read a noindex directive; blocking it in robots.txt is not a reliable way to remove it from search.

Run a launch-day checklist

Test the real domain after deployment. A successful build does not prove the correct version is serving at the public address. Confirm HTTPS, the preferred hostname, page status codes and the redirects for important old URLs. Check forms, phone links and any booking journey as part of the same launch.

Submit the updated sitemap in Search Console when you have verified access, and inspect a small set of priority URLs. Sitemap submission helps discovery; it does not guarantee indexing or preserve rankings. If changing domains, review Google’s site-move guidance and the conditions for using its Change of Address tool.

Watch the weeks after launch

Record the launch date and compare clicks, impressions, indexed pages and qualified enquiries against a suitable baseline. Some fluctuation is normal while search engines process changes. Look for patterns such as lost service URLs, unexpected noindex directives or a sharp drop isolated to pages that moved.

Google recommends keeping redirects for as long as possible, generally at least one year. Review new errors and update remaining old internal links. Do not claim that a redesign can guarantee unchanged rankings: the aim is to reduce avoidable disruption and make the new site useful.

If you are requesting a ZentroWeb redesign, bring the existing URL list and available Search Console data to the scoping conversation. Agree redirect ownership, launch verification and follow-up checks as named deliverables before development starts.
