Quick answer

You keep your rankings through a redesign by keeping what Google already trusts: every old URL redirects (301) to its closest new page, page titles and the searches they target stay the same or improve, the content that ranks is kept and rewritten rather than deleted, and the new site is at least as fast as the old one. Then you submit the new sitemap, watch Search Console for 404s for a month, and fix them. Most ranking losses after a redesign come from missing redirects and deleted pages, not from the new design.

Where rankings actually live

A common fear before a redesign is that the new look will somehow reset your Google position. It will not. Google does not rank designs. It ranks URLs, and it ranks them on the content, speed, links and signals attached to each one.

That means a redesign only loses rankings when it breaks those things: the URL changes and nothing redirects, the page that ranked gets deleted, the title that matched the search gets replaced with something clever, or the new site is heavier and slower. All four are avoidable, and all four are common.

Before you build: the inventory

Start with a list of every URL on the current site that matters. Export them from Google Search Console (Performance report, filtered to pages with impressions in the last 16 months) and from your sitemap. For each one, note the clicks, the main search it ranks for and where it will live on the new site.

That table is your redirect map, and it is the single most important document in the project. Build it before the design, not after.

Then decide, page by page: keep and rewrite, merge into another page, or retire. Pages with traffic are kept or merged. Pages with none can go, but they still get a redirect to the nearest relevant page.

The rules for the new content

Keep the search per page. If the old service page ranked for “drain repair Edmonton”, the new one targets the same phrase, ideally with the same or a better title. You can improve the copy, add an answer block at the top, add an FAQ and structured data; you should not change what the page is for.

Do not merge pages that rank for different things. Combining ten service pages into one “Services” page is the fastest way to lose ten rankings.

Improve, do not just move. A redesign is the moment to fix everything the old site got wrong: a direct answer at the top of each page, FAQ and LocalBusiness structured data, faster images, internal links between related pages. This is why rankings usually go up after a well-run redesign.

The redirect map

Every old URL gets a 301 (permanent) redirect to its closest new equivalent. Old service page to new service page. Old product to new product. Old blog post to the new post on the same topic, or the closest category page. Old category and tag archives to the new blog index.

Never redirect everything to the home page. Google treats that as a soft 404 and discards the ranking value. And never leave old URLs returning 404 “because nobody visits them”; if they are in Google’s index, Google visits them.

When we moved the Infinite Ideas blog to this site, 92 old posts were mapped individually to the nearest new article or service page. When House of Salma moved from WordPress to Shopify, every product and collection URL was mapped to its new Shopify address, because Shopify’s URL structure (/products/, /collections/) is fixed and different from WordPress.

Platform changes

Moving between platforms adds two complications. URL structures differ, so the redirect map is larger. And product or post data has to be exported, cleaned and imported: names, descriptions, images, prices, variants, categories. Keep product names and slugs as close to the originals as the new platform allows, and rewrite descriptions rather than pasting them, because thin product descriptions were probably part of what held the old store back.

Launch day checklist

  • Redirects live and tested on the ten most important old URLs, on a phone and a computer.
  • The noindex tag that protected the staging site removed from every page. This one has cost people months of traffic.
  • New XML sitemap submitted in Search Console; old sitemap URLs redirected to it.
  • Analytics and Search Console confirmed working on the new site.
  • Google Business Profile website link updated if the domain or path changed.
  • Speed checked on PageSpeed Insights mobile; the new site should be faster than the old one.
  • Structured data validated (Google’s Rich Results Test).
  • Robots.txt checked: nothing important blocked, AI crawlers allowed.

The month after

Check Search Console every day for the first two weeks. The Pages report will show 404s for any URL you missed; add redirects as they appear. The Performance report will show the new URLs being indexed and the old ones dropping out. Compare clicks and impressions for the 28 days after launch against the 28 days before. A dip in week one is normal while Google recrawls. A sustained drop after four weeks means a page or a redirect is missing, and the report will show which.

What it looks like when it goes right

House of Salma moved platform, changed every URL, rewrote every page, and came out ranking second on Google for its main search with 4.3 times the online orders. Prodigy Holidays replaced a site with no SEO at all and now scores 100 for SEO on Lighthouse with 68% more bookings. Neither had a dip worth mentioning, because the map was built before the site was.

Key takeaways
  • Rankings belong to URLs and content, not to designs. Map every old URL to a new one before you build anything.
  • Do not delete pages that get traffic. Rewrite them. If a page truly has to go, redirect it to the nearest relevant page, never to the home page.
  • Launch day is a checklist: redirects live, sitemap submitted, noindex removed, analytics working, Search Console watched.
  • A redesign is the best moment to fix speed, structured data and answer-first copy. Done right, rankings go up, not down.

Frequently asked questions

Will changing platforms (WordPress to Shopify) hurt my SEO?

Not if the migration is done properly. Shopify uses a fixed URL structure (/products/, /collections/, /pages/), so every old URL needs a 301 redirect to its new location. House of Salma moved from WordPress to Shopify with a full redirect map and now ranks second on Google for 'Islamic clothing Calgary'.

How long do I keep the redirects?

Permanently. Old links on other sites, in emails and in bookmarks never go away, and Google keeps checking them for a long time. Redirects cost nothing to keep.

Should I redirect old pages to the home page?

No. Google treats mass redirects to the home page as soft 404s and the ranking value is lost. Redirect each page to the closest equivalent: the same service, the same product, the same topic.

How soon after launch will I know if rankings held?

Watch Search Console daily for the first two weeks (coverage errors, 404s, indexing of new URLs) and compare clicks and impressions over 28 days against the same window before launch. A small dip in the first week is normal; a sustained drop means something is missing.

Do you handle the migration as part of a redesign?

Yes. Redirect mapping, content migration, sitemap submission and post-launch monitoring are part of every rebuild we do, including Revamp & Rescue projects on existing sites.
