Over the years I’ve watched businesses spend $30,000 on a gorgeous new website and quietly lose half their Google traffic the week it went live. The site looks a treat. The enquiries dry up. Nobody connects the two for months.
I’ve just finished analysing a freight-software company that did exactly this. Beautiful rebrand, sharp new design, and from an SEO point of view the wheels fell off. In September they showed up for roughly 235 search terms. After the rebuild, fewer than 50. Terms like “delivery management software” and “freight booking software” — gone. The page that used to rank fifth for “delivery software”? Redirected straight to the homepage, which doesn’t even contain the phrase.
That’s not bad luck. That’s a migration nobody planned. Let’s make sure it never happens to you or your clients.
Learning Objectives
A practical guide explaining how to carry out a website migration or website rebuild without losing organic search rankings. It covers SEO migration planning, redirect mapping, keyword preservation, indexation checks, common migration mistakes, implementation steps, Australian case studies, and recommendations for maintaining search visibility after launch.
By the end of this module you’ll be able to:
- Audit every keyword and page your current site ranks for before you touch the rebuild.
- Build a 1:1 redirect map so each ranking URL lands on a topically matched page — not the homepage.
- Rebuild your “money pages” with their original keyword targeting intact.
- Confirm your new pages are actually indexed after launch (a 301 that returns 200 is not the finish line).
- Spot the warning signs of a migration gone wrong and reclaim what slipped.
Key Concepts
- 301 redirect — a permanent “we’ve moved” instruction that forwards an old URL to a new one. Think of it like an Australia Post mail redirection when you move house: set it up properly and your mail — plus the ranking power the old page built up — follows you to the new address. Send it to the wrong address and it’s lost.
- Redirect map (URL mapping) — the spreadsheet that matches every old URL to its best new equivalent. This is the single document that decides whether your rebuild keeps its rankings or bleeds them.
- Link equity — the ranking strength a page has earned over time from backlinks and history. A well-planned 301 passes most of it along. A lazy redirect to the homepage flushes it.
- Topical relevance — Google ranks a page for a phrase partly because the phrase is on the page. If “delivery management software” ranked, the new page must actually contain and target that phrase. Ctrl+F is your friend here.
- Indexation — whether Google has actually filed your page in its catalogue. A page can return a healthy “200 OK” status and still sit unindexed. Like a book that’s been printed but never catalogued in the library — nobody can find it on the shelf.
- E-E-A-T (author signals) — Experience, Expertise, Authoritativeness, Trust. Author bios and “who wrote this” pages tell Google (and AI engines like ChatGPT) that a real, qualified person stands behind the content. Rebuilds routinely strip these out.
Real-World Case Studies
The following are de-identified composites drawn from real migration jobs. Names are fictional; the mistakes and the recovery numbers are the pattern I see again and again.
Case Study 1: Harlow Electrical — Commercial & Domestic Electrician — Ringwood, Melbourne
The Challenge: Harlow launched a rebrand on a new platform. Within six weeks their ranking keyword count fell from around 180 to roughly 55. Every service page — “switchboard upgrade Ringwood,” “EV charger installation Melbourne,” “ceiling fan installation” — had been 301’d to the homepage. Website enquiries dropped from about 40 a month to 14.
The Strategy: We pulled their old URL list three ways — Google Search Console, Ahrefs, and a Wayback Machine snapshot as backup — then rebuilt the top 12 service pages with their original keyword targeting. We mapped a 1:1 redirect for each old URL and resubmitted the sitemap.
The Results: Within 10 weeks the keyword count recovered to around 165 and enquiries climbed back to 38 a month. At their average job value, that’s roughly $18,000 AUD a month in recovered quote requests.
The Lesson: Redirecting a ranking service page to the homepage throws away the specific relevance that made it rank in the first place.
Industry Application: For trades, every suburb-plus-service page is a lead magnet. Treat each one like a shopfront on a different street — you wouldn’t board them all up and put one sign on head office.
Case Study 2: Marina Bay Dental — Dental Practice — Bondi Junction, Sydney
The Challenge: New site, cleaner design. Their blog of 32 articles was migrated and the redirects returned a healthy status code — but the posts simply weren’t reindexed. Rankings for “teeth whitening Bondi” and “emergency dentist Eastern Suburbs” vanished. New-patient bookings from organic search fell about 35%.
The Strategy: In Google Search Console we diagnosed the gap in the Pages report — dozens of URLs sitting under “Crawled – currently not indexed.” We added dentist author bios (the E-E-A-T signals the rebuild had dropped), tightened internal linking so the posts weren’t orphaned, and requested indexing.
The Results: Over 8 weeks, 28 of the 32 posts were reindexed and organic bookings lifted 40% off their post-launch low — around $9,500 AUD a month in recovered new-patient value.
The Lesson: A redirect that returns “200 OK” isn’t done. You have to confirm Google actually indexes the page.
Industry Application: Medical and dental — the patient journey mirrors the customer journey. Author pages don’t just build patient trust; they’re increasingly what AI engines cite when someone asks, “who’s a good dentist in the Eastern Suburbs?”
Case Study 3: Cobblestone & Co. — Homewares Retailer (e-commerce) — Fitzroy, Melbourne
The Challenge: A platform migration from an old custom cart to a new build changed the entire URL structure. Hundreds of product and category URLs were either 301’d to the homepage or dropped altogether. Rankings for “brass tapware” and “handmade ceramic dinner set” collapsed, and organic revenue fell about $22,000 AUD a month.
The Strategy: We exported the old URL list, built a redirect map pointing each old category and product URL to its true new equivalent, restored the category page copy that had been stripped in the redesign, and fixed the canonical tags.
The Results: Over 12 weeks organic sessions rose 65% off the low and organic revenue recovered to around $19,000 AUD a month.
The Lesson: On e-commerce, category pages are your ranking workhorses. Map them carefully — don’t dump them at the homepage door.
Industry Application: Retail — foot traffic is web traffic, and merchandising is on-page UX. A category page redirected to the homepage is a shuttered aisle with a note on the door.
Implementation Guide
Step 1: Inventory everything you rank for (before you touch the new site)
What it looks like: Export your ranking URLs and keywords from Google Search Console (Performance → Pages) and, if you have it, Ahrefs (Top Pages and Organic Keywords). Take a Wayback Machine snapshot of the old site as a backup record.
Pro tip: Sort by clicks. Protect your top 20% of pages first — that handful usually drives the bulk of your leads.
Step 2: Crawl the old site and build a full URL list
What it looks like: Run Screaming Frog over the live old site and export every indexable URL. This is your master list of what exists today.
Pro tip: Crawl the staging site too, before launch. Comparing the two lists shows you exactly which pages are about to go missing — while you can still do something about it.
Step 3: Build a 1:1 redirect map (old URL → best new URL)
What it looks like: A simple spreadsheet: old URL | keyword it ranks for | best new URL | notes. One row per page. This is the document that saves the migration.
Pro tip: The homepage is the redirect of last resort. Only send a URL there if there’s genuinely no equivalent page. If “delivery management software” ranked, it needs to land on a delivery-software page — not the front door.
Step 4: Rebuild the money pages with their original keyword targeting
What it looks like: For each high-value page, make sure the new version actually contains and targets the phrase it used to rank for — in the heading, the copy, and the page title.
Pro tip: Ctrl+F your target keyword on the finished page. If the phrase isn’t there, the page can’t rank for it. In the freight example I opened with, the homepage they redirected to didn’t contain “delivery management” anywhere. Game over before it started.
Step 5: Launch, then verify redirects, status codes, and indexation
What it looks like: Re-crawl the live site. Confirm redirects are single-hop 301s (not 302s, not chains, not 404s). Submit the new sitemap in Search Console and watch the Pages report for “Crawled – currently not indexed.”
Pro tip: Within 48 hours, spot-check your top 10 pages. Run a site:yourdomain.com.au/your-page search in Google — if it doesn’t appear, it isn’t indexed yet, and you can request indexing straight away.
Step 6: Monitor for 8–12 weeks and reclaim losses
What it looks like: Track your keyword count and top positions weekly. A migration always loses a little in the wash — the job is to catch the stragglers and fix them fast.
Pro tip: Keep the old ranking export from Step 1 open beside your new one. Any keyword on the old list that’s missing from the new one is a to-do item, not a mystery.
Common Pitfalls & Solutions
- Pitfall: Redirecting every old page to the homepage → Fix: Map each URL to its closest topical equivalent → Prevention: Build the redirect map before launch, not after.
- Pitfall: Redirect returns a healthy status code but the page never gets indexed → Fix: Request indexing, fix internal links, beef up thin content → Prevention: Run a post-launch indexation check in Search Console within the first week.
- Pitfall: The target keyword is missing from the new page → Fix: Rewrite the page to include and target it → Prevention: Add keyword-to-page mapping to the build brief so the designer and copywriter know what each page must cover.
- Pitfall: Author and trust signals stripped in the redesign → Fix: Add author bios and “about the author” pages → Prevention: Bake author blocks into the page template from day one.
- Pitfall: Redirect chains, loops, or lazy 302s → Fix: Replace with single-hop 301s → Prevention: Re-crawl both staging and live and check every status code.
- Pitfall: Duplicate homepage copies left lying around (e.g. a stray
home.version) → Fix: Canonicalise or remove them → Prevention: Crawl for duplicate templates before and after launch.
Practical Exercise
- Quick Win (5 mins): Open Google Search Console → Performance → Pages, sort by clicks, and screenshot your top 20 URLs. That’s your “do not lose” list. Pin it somewhere the web team can see it.
- Deep Dive (30 mins): Build a redirect map for your top 25 pages in a spreadsheet — old URL, keyword it ranks for, new URL, status. If you can’t yet name the new URL for a page, that’s a page someone needs to build.
- Real Business Application:
- Trades: List every suburb + service page you have. Each one needs a matching new page — not a homepage redirect.
- Medical/Dental: Check that every migrated blog post and every practitioner bio survived the move and is indexed.
- Retail: Map every category page one-to-one. Category pages, not the homepage, are where your rankings live.
Tools & Resources
- Google Search Console — free — your before-and-after baseline and your indexation checker. Non-negotiable.
- Screaming Frog SEO Spider — free up to 500 URLs, paid above that — crawl the old and staging sites to build your URL list and catch bad redirects.
- Ahrefs — paid — pull the full list of keywords and pages you rank for, so nothing gets left behind.
- Wayback Machine (archive.org) — free — recover old URLs and page content if the site’s already been rebuilt over the top.
- Bing Webmaster Tools — free — get the new site indexed in Bing too. Bing’s index feeds ChatGPT, so it’s an underused way to stay visible in AI answers. Most Australian SMBs skip it — that’s the opportunity.
- Redirect map template — a plain spreadsheet with columns for old URL, keyword, new URL, and status. Simple beats clever here.
Module Summary
- A website rebuild without a migration plan is the most common way I see businesses accidentally delete their own rankings. The freight-software example lost roughly 185 keywords overnight.
- The homepage is the redirect of last resort. Every ranking page deserves a topically matched new home, and the target keyword must actually appear on that page.
- A redirect returning “200 OK” is not the same as being indexed. Always confirm indexation in Search Console after launch.
- Inventory before, verify after. The old ranking export is your checklist for reclaiming anything that slipped in the first 8–12 weeks.
Keyword Intelligence
Live Australian search data (Ahrefs, AU, pulled July 2026). Difficulty (KD) is Ahrefs’ 0–100 estimate of how hard the top 10 is to crack. CPC is converted from Ahrefs’ USD figure to approximate AUD and should be treated as a guide, not a quote — verify in Google Ads before committing budget.

SEO suggestions to make this piece pull its weight
- Anchor the page on the low-competition winners. “website migration checklist” (KD 4) and “seo migration” (KD 7) are the softest, most commercial targets here. Lead your title and H1 with one of them — for example, “Website Migration SEO Checklist: Rebuild Without Losing Rankings.”
- Offer the redirect map template as a download. People searching “website migration checklist” want a tool, not a lecture. A downloadable spreadsheet is exactly the asset that wins that query and earns links.
- Add a short FAQ block targeting the informational long-tail — “how to do a 301 redirect,” “what is a redirect map,” “why did my rankings drop after a redesign.” These pick up featured snippets and AI Overview citations without competing head-on with the tough terms.
- State facts plainly for AI visibility. Phrases like “a 301 redirect passes most link equity” and “Crawled – currently not indexed means Google found the page but hasn’t listed it” are the kind of explicit, verifiable statements AI engines quote. Write to be cited, not just to rank.
- Get it into Bing. Once published, submit the URL in Bing Webmaster Tools. It’s a five-minute job that most competitors won’t bother with, and it’s how you show up when someone asks ChatGPT about website migrations.
