Redesigning a website without losing your Google rankings

The way to keep your Google rankings through a redesign is to carry everything the old site has built up in search across to the new one, in full. That takes five steps: take an inventory of every address and valuable page on the old site, prepare an address-mapping table linking each old address to its new equivalent, move the content without losing it, switch on permanent 301 redirects on launch day, and watch Search Console for weeks afterwards. Skip them, and however good the new site is, you may lose visitors in the first months.

Below we walk through each step in the order we follow on redesign projects.

Why rankings fall after a redesign

Google knows a page by its address. Over the years, other sites have linked to that address, and the page has settled into a certain place for certain searches. When the same content is published at a different address on the new site, Google cannot know that on its own. The old address returns a 404 error; the new one starts from nothing.

The causes of loss we see most often are these:

No redirects. The old addresses simply disappear.
Everything redirected to the home page. Google often treats this not as a redirect but as a page that has gone.
Content cut back. A long service page that brought in traffic is reduced to three sentences, because “the new design should be cleaner”.
Titles and descriptions lost. On the new system, page titles are left at their default values.
Blocks left over from testing. On going live, robots.txt rules or a noindex tag are left switched on.
Broken internal links. The menu changes, and links between old articles now lead nowhere.

None of these has anything to do with design. All of them have to do with planning.

Preparation: inventory and address mapping

Step 1: Take an inventory of the old site

Before the redesign begins, whilst the old site is still live, take a snapshot of it. You cannot protect what you might lose without knowing what it is.

Every address. List every page, image and document on the site with a crawling tool. Add the sitemap.
Pages that bring traffic. From the Performance report in Search Console, export the pages and queries with the most clicks over the last 12 months.
Pages that receive links. Note the addresses that other sites link to. If these are not redirected, the value coming from outside is lost too.
Page-level details. For each important page, its title, description, main heading and structured data.

This inventory becomes the yardstick you compare against once the redesign is done. Without recording the starting figures, you cannot later answer the question “has traffic dropped?”

Step 2: Prepare an address-mapping table

This is the most important document in a redesign. Line by line, it records where each old address will go on the new site.

Old address	New address	Action	Note
/our-services/implants.html	/services/implants	301	Same content, new address
/blog/?p=124	/journal/receding-gums	301	Article moved and expanded
/campaign-2023	/services	301	Closest current page
/old-team/james	/team	301	Individual page merged
/test-page	—	410	No value; removed permanently

The rules we follow when preparing the table:

One-to-one mapping comes first. Each old page should go to the new page closest in subject. The home page is the last resort.
No chains. An old address should go straight to its final address, with no other redirects in between.
One address format. http and https, www and non-www, with and without a trailing slash — all should resolve to a single format.
Do not forget images and documents. Photographs that bring traffic from image search, or frequently downloaded PDFs, belong in the table too.

If the old and new address structures can stay the same, that is the safest route. But if the old structure is muddled, a redesign is a good chance to tidy it. What matters is that every change is written into the table.

Step 3: Map the content, do not cut it

Content mapping matters as much as address mapping. Google judges a page not only by its address but by its content. If the new address holds a much weaker page than the old one, rankings can fall even with a redirect in place.

Carry the copy of pages that bring traffic across to the new page. Rewrite it if need be, but keep the question it answers.
Write page titles and descriptions with the old performance in mind. Think twice before changing a title that works well.
The heading hierarchy, image alternative text and structured data should all be there on the new site.
Merging several weak pages into one strong page can be a good decision. In that case, all of them redirect to that page.

A redesign is also a chance to improve the content: out-of-date information is refreshed, missing questions are answered. But that improvement should build on the existing value, not erase it.

Step 4: Launch day

Launch day follows a checklist:

Switch on 301 redirects at server level. Google recommends permanent server-side redirects from old addresses to new ones; 301 and 308 are such redirects. JavaScript redirects written into the page are no substitute.
Test the redirects. Check every line of the mapping table with a tool: does it go to the right address, in a single step, and return a 301?
Check robots.txt and noindex. Make sure no blocks from the test environment remain on the live site.
Submit the new sitemap. Add it in Search Console. It should contain only new addresses that you want indexed.
If the domain has changed, report the change of address. Search Console’s Change of Address tool is used only when moving from one domain or subdomain to another. It is not needed for a move from http to https, a www change, or address changes within the same domain.
Test analytics and forms. Is the measurement code working on the new site? Are forms really being sent?

Redirects should be permanent. Google recommends keeping them in place for as long as possible — generally for at least a year. These details are set out in Google’s guide to site moves.

Step 5: Monitor after launch

A redesign does not end on launch day. It takes Google time to crawl the new addresses and carry the old signals across. Some fluctuation in rankings during this period is normal. What matters is making sure the fluctuation does not turn into a lasting fall.

What we look at in the first weeks:

The indexing report. Are the new pages being indexed? Are any old addresses reporting “Not found (404)”?
The Performance report. Clicks and impressions for the important pages and queries noted in the inventory, compared with the earlier period.
Crawl errors and redirect problems. Addresses forgotten in the mapping table usually surface here. Each one is added to the table and redirected.
Page speed. Are the Core Web Vitals on the new site within the “good” threshold on mobile? See why is my website slow?
External links. You can ask the sites that give you your most valuable links to update them to the new address.

For most sites, checking weekly in the first month and fortnightly for the next two months is enough. All of this monitoring is part of our SEO and maintenance service. You will find the general audit items in our technical SEO checklist.

When to start afresh, and when to improve

Not every old site needs replacing. Sometimes fixing page speed, titles and content structure brings the same gain as a new site, with less risk. And sometimes the old foundations are so heavy that patching them becomes a constant burden. Making that call requires looking at the old site.

The choice of platform is part of the redesign too. Moving from a site built on off-the-shelf themes and plugins to a custom-built site almost always changes the address structure. We compare the two in WordPress or a custom-built website?, and explain why regular care matters after a redesign in why website maintenance matters.

On new sites, we set up a clean address structure from the start, with static, fast pages, structured data and a complete sitemap. On the 85-page site we built for the psychologist Gülşah Yalçın, every page is in the sitemap and the Lighthouse SEO score is 100; the details are in the case study. We do not promise rankings; we report everything we measure.

Frequently asked questions

Will my rankings drop at all after a redesign?

Some fluctuation in the first weeks is normal, whilst Google crawls the new addresses. With a complete mapping table, server-side redirects and content carried across intact, that fluctuation should settle rather than become a lasting fall.

Can I simply redirect every old page to the home page?

No. Google often treats a blanket redirect to the home page as a page that has disappeared. Each old address should go to the new page closest in subject, with the home page only as a last resort.

How long should redirects stay in place?

For as long as possible — Google’s guidance is generally at least a year. Until then, keep the mapping table to hand, so that any forgotten address can still be added.
