The checklist we follow when relaunching WordPress and Shopify sites, so a new design keeps the rankings and traffic the old site earned.

A new design should bring more traffic, not less. Yet many businesses relaunch a beautiful WordPress or Shopify site and then watch their rankings slide for months. Website redesign SEO is the work that prevents that drop.

The good news is that most losses come from a handful of avoidable mistakes. In this checklist, we’ll cover what to do before, during and after a relaunch, plus the platform-specific checks we run on every WordPress and Shopify rebuild.

Quick Answer: The Website Redesign SEO Essentials

If you remember nothing else, protect these five things:

What to Protect	How
URLs that rank or have backlinks	Keep them, or 301-redirect each one to its closest new page
Content that ranks	Keep the substance, even if the layout changes
Titles, descriptions and headings	Carry them over, then improve them carefully
Internal links	Rebuild them in the new menus and templates
Indexing	Remove staging blocks and submit a fresh sitemap at launch

Why a Website Redesign Can Hurt SEO

Search engines rank pages, not designs. When a redesign changes URLs, removes content or breaks internal links, Google has to work out the site again from scratch.

The most common causes of lost traffic are old URLs that return 404 errors instead of redirecting, ranking pages deleted because they “didn’t fit” the new design, and long, useful content replaced with short, image-heavy sections. Others include a staging noindex setting that goes live with the new site, and slower pages caused by heavy animation and large media. Each of these can be caught with a checklist, so let’s go through it.

Before the Redesign: Set Your Website SEO Baseline

You can’t protect what you haven’t measured. So before any design work starts, capture how the current site performs.

Crawl the Current Site

Use a crawler such as Screaming Frog to export every URL, title, meta description, heading and canonical tag. This list becomes the source for your redirect map and your content checklist.

Export Your Top Pages and Keywords

In Google Search Console, export the pages and queries that brought the most clicks over the past twelve months. Then mark the pages you must keep, because they earn most of your traffic.

Record Backlinks and Benchmarks

Next, list the pages other websites link to, using your SEO tool of choice. Also note current organic traffic, conversions and Core Web Vitals, so you have something to compare against after launch.

During the Redesign: SEO Checks on Staging

Once the new site takes shape, test it on a staging server before anyone sees it.

Map Every Old URL to a New One

Ideally, keep your existing URLs. If they must change, create a one-to-one redirect map in which every old URL points to its most relevant new page with a 301 redirect.

What we recommend: avoid sending everything to the home page. Google treats mass redirects to the home page much like missing pages. Its guide to site moves with URL changes explains the process in detail.

Keep Content, Titles and Metadata

A redesign is a good moment to improve content, but not to delete it. Carry over the text that ranks, together with its title tag, meta description and main heading. If you rewrite a top page, keep the same topic and target keyword.

Protect Internal Links, Images and Structured Data

New menus often drop links to important pages. Therefore, check that your key pages are still linked from the navigation, footer or related content. Also confirm that images keep their alt text, and that structured data such as Organization, Article, Product and Breadcrumb markup still validates.

Check Speed, Mobile and Crawlability

Run the main templates through PageSpeed Insights on staging. A new design that is slower than the old one can undo the rest of your SEO work. In addition, make sure important content is in the HTML rather than loaded later by JavaScript, because search engines and AI assistants read server-rendered pages most reliably, as we explain in our guide to AI search optimization.

WordPress Redesign SEO Checks

WordPress relaunches have a few specific traps:

“Discourage search engines” setting: staging sites often have it ticked under Settings, then Reading. Untick it on launch day, or the whole site can drop out of search.
Permalink structure: keep the same permalink setting. Changing it, for example by adding or removing dates, changes every post URL at once.
SEO plugin data: if you switch themes or SEO plugins, migrate your titles, descriptions and focus keyphrases, then spot-check them on the live site.
Redirects: use a redirect manager, such as the one in Yoast SEO Premium or the Redirection plugin, so you can track 404s and fix them quickly.
Media URLs: if media moves, redirect old image URLs too, because image search traffic is easy to lose.

Shopify Redesign SEO Checks

Shopify relaunches are often a theme change, and that has its own checklist:

Theme switches keep URLs: product, collection and page URLs stay the same, which protects most rankings automatically.
Metadata output: check that the new theme outputs your titles, descriptions and structured data correctly. Themes differ more than people expect.
Leftover app code: remove snippets from apps you no longer use, because they slow the new theme down.
URL redirects: if you rename products or collections, Shopify can create redirects automatically, but always confirm the box is ticked.
Collection content: carry over collection descriptions, since they often rank for valuable category keywords.

Our Shopify SEO checklist covers the full set of on-page checks for the new theme.

Moving Between WordPress and Shopify

Changing platform is the riskiest kind of redesign, because almost every URL changes. Shopify uses fixed paths such as /products/ and /collections/, while WordPress and WooCommerce use their own. So a complete redirect map is essential, alongside migrating products, customers and content. Our guide to migrating to Shopify walks through the full process.

Launch Day Checklist for Website Redesign SEO

On launch day, work through this list in order:

Remove noindex tags and password protection from the new site.
Check that robots.txt doesn’t block important sections.
Switch on the redirect map, then test a sample of old URLs.
Confirm that canonical tags point to the live domain, not staging.
Submit the new XML sitemap in Google Search Console.
Test forms, analytics and conversion tracking.
Crawl the live site again and fix any 404 errors or redirect chains.

Only use Search Console’s Change of Address tool if you’re also moving to a new domain.

After Launch: Monitor Website SEO for 90 Days

Some ranking movement after a relaunch is normal while Google recrawls the site. However, a steady decline after the first few weeks usually means something is broken.

For the first three months, check Search Console weekly for new 404s and excluded pages. Then compare clicks and impressions for your top pages with your baseline, look for redirects that land on the wrong page and watch Core Web Vitals in the field data. Keep redirects in place for at least a year, and longer if old URLs still have backlinks. Google’s guide to redirects and Google Search covers the details.

Common Website Redesign SEO Mistakes

These are the problems we see most often when a site is relaunched without a plan:

Launching with WordPress’s “Discourage search engines” option still ticked.
Changing the whole URL structure at once, with no redirect map.
Deleting blog posts because they look old, even though they bring traffic.
Moving key content into tabs, sliders or images that are hard to crawl.
Leaving the old sitemap in Search Console.
Redirecting old URLs in chains, such as A to B to C.

Frequently Asked Questions

Will a website redesign hurt my SEO?

Not if you plan it. A redesign that keeps URLs or redirects them properly, preserves content and stays fast usually holds its rankings. In fact, it often improves them, because the new site is faster and better structured.

How long does it take rankings to recover after a redesign?

Small fluctuations usually settle within a few weeks. If traffic is still falling after a month or two, audit redirects, indexing and content changes straight away.

Should I change URLs during a redesign?

Only when there’s a clear benefit, such as removing dates or messy parameters. Every changed URL needs a redirect, so keep changes to a minimum.

Do I need an SEO specialist for a website redesign?

For a small site, a careful developer with this checklist is usually enough. For larger sites, stores or platform changes, involve someone with website redesign SEO experience from the start.

Final Thoughts

Website redesign SEO comes down to one principle: don’t throw away what already works. Measure the old site, map every URL, keep the content that ranks, run the platform checks and monitor closely after launch.

Do that, and a redesign can lift your traffic instead of resetting it. Planning a relaunch on WordPress or Shopify? Talk to us before design work starts, and we’ll build the SEO plan into the project.
