How to redesign a website without losing search rankings

A website redesign can lower your Google rankings. It happens when the new site changes URLs, removes pages, or rewrites content that was bringing in visitors. The risk is real, but it is also preventable.

Most ranking losses trace back to a few causes. Pages move to new addresses with no redirects. Text that matched a search gets cut. The new site launches with a setting that tells Google to stay away. This checklist covers each one in the order the work happens.

Record what you have before anything changes

Start with a full list of the pages on the current site. A crawling tool can produce this list. Many agencies use Screaming Frog for it. Save the result in a spreadsheet with one row per URL.

Next, pull search data from Google Search Console. Export the pages that get clicks and the queries that bring people to them. Also note the pages that earn links from other websites. Google Analytics will show which pages lead to calls, forms, or sales.

This record is your baseline. After launch, you compare the new numbers against it. Without a baseline, no one can say whether the redesign helped or hurt.

Sort pages into keep, merge, and remove

Go through the list and label each page. Pages that rank or convert get the label keep. Thin pages that cover the same topic as another page may be merged. Pages with no traffic, no links, and no purpose can be removed.

Be careful with the keep group. A service page that ranks on page one for a local search is an asset. The redesign should change how it looks and works. It should not strip out the headings, text, and details that earned the ranking.

Tell the agency which pages matter most. The brief is the right place for this. Our guide on how to write a website design brief for an agency lists what to include, and the pages that already perform well belong on that list.

Keep URLs the same where possible

A URL is the address of a page. Google ties a page’s ranking history to that address. If the address stays the same, the history stays with it.

A new design does not require new URLs. If a service page lives at /services/web-design/ today, it can live there after the redesign. Keep the same structure unless there is a clear reason to change it.

Sometimes a change is needed. A new platform may force a different URL format. A restructured menu may move pages into new sections. In those cases, every changed URL needs a redirect.

Build a redirect map

A redirect sends a visitor and Google from an old URL to a new one. Use a 301 redirect, which tells search engines the move is permanent. A 302 redirect marks the move as temporary and is the wrong choice here.

The redirect map is a spreadsheet with two columns. The left column holds each old URL. The right column holds the new URL that replaces it. Point each old page to the closest matching new page. Do not send everything to the home page. Google may treat a redirect to an unrelated page as a missing page.

Removed pages with traffic or links should redirect to the nearest related page. If no related page exists, a 404 or 410 response is acceptable.

Include old image URLs and PDF files if they get traffic or links. These are easy to forget.

Carry over the on-page details

Each page has parts that tell Google what it covers. These are the title tag, the meta description, the main heading, the subheadings, and the body text. Image alt text counts as well.

Copy these into the new design for every page in the keep group. Rewrites are fine when the new text still covers the same topic and answers the same questions. Cutting a 900-word page down to 150 words to fit a cleaner layout can cost you rankings.

Check the internal links too. The links between your pages help Google understand which ones matter. A new menu that drops a key page from the navigation weakens that page.

Test on a staging site and block it from Google

The agency should build the new site on a staging site, which is a private copy not meant for the public. Staging sites should be blocked from search engines so Google does not index a duplicate version of your site.

That block creates the most common launch error. Most staging sites carry a noindex tag or a robots.txt rule that keeps search engines out. If that setting goes live with the site, Google drops your pages from results. Add it to the launch checklist: remove the block, then confirm it is gone.

On staging, test the redirects with the redirect map. Click through the main pages. Check that titles, headings, and structured data came across. Review the site on a phone, since Google uses the mobile version of a page for indexing.

Launch and check the same day

Pick a launch day when traffic is lower. Avoid a week with a major sale or event.

After the site goes live, run these checks:

• Open the robots.txt file and confirm it does not block the whole site
• View the source of the home page and confirm there is no noindex tag
• Test a sample of old URLs and confirm each one redirects to the right page
• Submit the new XML sitemap in Google Search Console
• Crawl the new site and look for broken links and redirect chains

If the domain name changed, Search Console has a Change of Address tool. Use it after the redirects are live. Add and verify both the old and new domains first.

Watch the numbers for the next few weeks

Check Search Console every few days after launch. Look at the Pages report for new errors and for pages Google has excluded. Check that the pages in your keep group are still indexed. If rankings fall and the cause is not clear, a technical SEO audit can trace it.

Rankings can move for a short time after a redesign. Google needs to crawl the new pages and process the redirects. Small swings in the first weeks are normal. A steady drop on pages that used to perform well is a sign to check redirects, content changes, and indexing.

Keep the redirects in place for at least a year. Google recommends this length for site moves. Many sites keep them much longer, since old links from other websites continue to point at the old addresses.

Compare clicks, impressions, and conversions against the baseline you saved at the start. If a page lost ground, compare its old and new versions. The cause tends to be a missing heading, cut text, or a redirect that points to the wrong page.
