Website Redesign SEO: Will a New Site Hurt Your Rankings?

If your current website already brings in enquiries from Google, a redesign can feel like a gamble. Nobody wants to swap a steady trickle of calls for a prettier site that nobody finds.

Rankings are rarely lost because a site was redesigned. They are lost because something specific was changed without anyone writing it down. This guide covers what those things are, what to keep, and what to check before and after launch.

Will a website redesign hurt your Google rankings?

A redesign can hurt your rankings if page addresses, content or technical basics change carelessly, and it need not if they are handled properly. Keep the addresses that already rank, carry across the wording and titles that bring enquiries, redirect anything that moves, and check the launch. Done that way, a redesign is far more likely to help than harm.

Google’s own page on debugging drops in search traffic lists site moves as one of the main causes, and is specific about the trigger: if you change the URLs of existing pages, you may see ranking fluctuations while Google recrawls and reindexes the site. The addresses are the trigger, not the design.

What actually causes rankings to drop in a redesign?

There are four causes, and a new look is not one of them.

• Page addresses change and nothing points the old ones at the new ones. Google knows your pages by their addresses. Change one with no redirect and, as far as Google can tell, the old page has gone and a new one with no history has appeared.
• The content that ranked is cut or rewritten. If a page ranked because it answered a question in detail, and the new version is three lines and a photo, the reason it ranked has been removed.
• Titles and headings are lost. Page titles sit behind the scenes, so they are easy to forget in a rebuild. Google describes the title shown in results as often the primary piece of information people use to decide which result to click, and it draws that title from your title element and headings.
• A technical setting blocks Google. New sites are built in private, with a setting that tells search engines to stay away. If that setting goes live with the site, Google’s documentation is blunt about the result: a page carrying a noindex rule is dropped entirely from search results.

What should you keep from the old site?

Start by finding out what the old site is good at. Open Search Console and note which pages get clicks and which searches bring them. Then protect those things.

The addresses, wherever you can

A new design on the same URLs is the lowest risk way to redesign a site. Only change an address when there is a real reason to, such as a page that is being merged or a structure that no longer makes sense.

The pages and wording that already bring enquiries

Improve the words, but do not thin them out. If a service page ranks and brings calls, the new version should cover everything the old one did, in the same plain language your customers search in. The same goes for pages that look dull but quietly work, like an old FAQ.

Titles and headings that work

Copy the title and main heading of every page that ranks into a spreadsheet before the old site comes down. Carry the working ones across unchanged. Our guide to SEO web design covers how headings and structure should be set up in a new build.

Why does every old address need a 301 redirect?

Where an address has to change, a redirect tells visitors and Google where the page went. A 301 is the permanent kind. Google’s redirects documentation explains the difference: with a permanent redirect, Google treats it as a signal that the new address should be the one it shows. With a temporary redirect it does not.

Google’s site move guidance adds four rules worth following to the letter:

• Map each old address to its own new address. Google warns against redirecting many old URLs to one irrelevant destination such as the home page, which can confuse visitors and may be treated as a soft 404, in other words as a missing page.
• Keep chains short. Point the old address straight at the final one, not through two or three stops on the way.
• Update your own links. Menus, buttons and links inside your pages should point at the new addresses directly.
• Leave the redirects in place. Google’s advice is to keep them for as long as possible, generally at least a year.

Pages you are retiring for good should return a proper not found response, which is what Google asks for. We set out how to build the redirect map itself, row by row, in our website migration checklist.

What should you check before launch, and in the weeks after?

Google also advises splitting a move into smaller steps where that makes sense. Change the design, the platform and the domain one after another, and if something dips you will know which change did it. If the domain is moving too, read how to transfer a domain name first.

How long does any wobble normally last?

If the addresses stay the same and the content is carried across, there may be very little to see. If addresses change, expect some movement. Google’s site move guidance says to expect temporary fluctuation in ranking, and that for a medium sized site it can take a few weeks or more for Google to start showing the new URLs, longer for larger sites. It also says rankings settle down over time.

Google gives no fixed number of days. A change of hosting on its own is gentler still: Google describes a temporary drop in how often it crawls the site right after launch, followed by a steady increase over the next few days.

The practical test is direction. A dip that recovers week by week is Google catching up. A page that vanishes completely is a fault. If that happens, our guide to why a website is not showing on Google helps you tell an indexing fault from a ranking one.

When does a redesign help your rankings?

Often. Many of the sites we are asked to redesign have been left alone for years. A rebuild is the natural moment to fix what was holding the old site back:

• Speed. Google states that Core Web Vitals are used by its ranking systems. It also says it aims to show the most relevant content even when page experience is poor, so speed supports good content and does not replace it. See how to improve WordPress speed.
• Headings that say what you do. On one shop we audited, the main heading on the home page was just the brand name, which tells Google nothing about what the business sells.
• Descriptions that fit. The same shop had search descriptions running to 446 characters, so every one was cut off mid sentence in the results. We rewrote all eight.
• Thin or duplicated pages. Four collection pages on that site carried word for word identical copy. A redesign is the time to give each page its own job.

A website audit of the old site before the redesign starts will show you which of these apply to you.

How we handle rankings in a redesign

Our builds run in five steps: plan and design, build and test, your preview, final checks, launch and support. The search work sits in the first and fourth. At the plan stage we list what the old site ranks for and which addresses must survive. At final checks we test the redirects, the titles and the indexing settings before anything goes live. The full detail is in our web design process.

Some examples from real jobs:

• We moved a Canterbury watch dealer’s shop off Wix and onto a new build. We kept the page addresses Google already knew the same through the move, and switched the live shop over with no downtime.
• We rebuilt the site of a Maidstone scrap metal collector whose owner felt the old one was poorly optimised. In Search Console for the 28 days to 26 September 2026, the rebuilt site sat on page one for named local searches including “scrap metal maidstone” and “scrap metal kent”.
• On a membership site we look after, a button in a welcome email was still pointing at a retired domain and returning a not found page. It was fixed the same morning. Old addresses hide in emails, PDFs and social profiles, not only in menus.
• We receive Search Console alerts for client sites after launch, including not found and canonical issues, so a missed address reaches us and gets dealt with.

We also do the fiddly parts for you. When we sent a Ramsgate property developer step by step instructions for pointing his domain at his new site, his reply was that he did not “want to mess everything up”. So we did it for him.

How we put this together

Every statement about how Google treats redirects, site moves, indexing and page experience comes from the Google Search Central documentation listed below. Where Google gives no figure, we have not supplied one.

The examples are from our own client work in Kent in 2026, with businesses described by trade and area. The scrap metal figures are 28 days from one small site. They show where the rebuilt site sits now, and we make no claim about what the old site ranked for.
