A Pilates studio owner in Stellenbosch watched her bookings fall from thirty a month to four. The practice had moved to a prettier website platform in March, and nothing else had changed. She typed her own service into Google and scrolled past two pages of competitors. Her old site had sat on page one for years. The new one was nowhere.
What is a website migration?
A website migration is any change big enough to alter how your site appears to Google: a new platform, a new design, new page addresses, or a new domain name. Google keeps a record of every page it has found, and it decides where each page shows up when someone searches. Those positions are your rankings. When you migrate, Google has to match every old page to its new home. A clean match carries your positions across. A missed match reads as a missing page, and the position goes with it. The software swap is the visible part of a migration; the matching underneath decides what you keep.
Key Takeaways
- Compare platforms on measurable criteria: speed, control over page addresses, redirect support, and content export. Sales pages compare none of these.
- Rankings attach to page addresses. Change the addresses without redirects and Google reads your pages as gone.
- Content parity counts as much as redirects. The new page must carry what the old page earned its position with.
- Time the move for your slow season and keep redirects in place for at least a year afterwards.
- Some migrations shouldn't happen. If the platform isn't the problem, moving adds risk and fixes nothing.
- Recovery is measurable within weeks in Google's free reporting tools, but only if you record your numbers before the move.
How to compare website platforms without the marketing gloss
A platform comparison worth doing measures four things: page speed, control over page addresses, redirect support, and content export. A sales page compares adjectives; a spreadsheet compares facts. Platform marketing leans on words like effortless and powerful, and neither can be checked. The four criteria can. Google grades speed through Core Web Vitals, three published measures of loading, responsiveness, and visual stability, so you can test any live site built on the platform you're considering. Address control means you decide the exact web address of every page you publish. Redirect support means the platform can forward an old address to a new one without a paid add-on. Export means your content can leave with you when you outgrow the software. The table below pairs each marketing claim with the check behind it.
*The four checks behind an honest platform comparison.*
| Criterion | The Sales Page Says | What To Check |
|---|---|---|
| Speed | "Blazing fast" | Core Web Vitals scores on real sites using the platform |
| Page addresses | Nothing | Full control over every page's web address |
| Redirects | Nothing | Permanent redirects without plugins or paid add-ons |
| Content export | "Easy import" | Whether every page and image can leave with you |
A platform failing the address or redirect check will cost you at your next move, whatever its theme gallery promises.
What a website migration puts at risk
The risk in a website migration concentrates in three places: page addresses, redirects, and content parity. Every page on your site lives at a web address, its URL, and Google's records attach to the address rather than the design. When a rebuild changes /services/back-pain to /treatments/back-pain, Google finds a missing page at the first address and a stranger at the second. The position the old page earned over years does not move across on its own.
A redirect closes the gap. It works like a forwarding order at the post office: anyone arriving at the old address, Google included, gets sent on to the new one. Google's documentation on redirect types confirms a permanent redirect tells Google the new address should stand in the old one's place. Content parity is the third exposure, and the least discussed. Rebuilds trim word counts, merge pages, and drop the detail a page earned its position with. A migration keeping every address but shedding a third of its content has still lost a third of its evidence, and rankings tend to follow the evidence out the door.
Planning a migration to protect your rankings
A protected migration is an inventory exercise before it is a design exercise. Start with a full list of every address on the old site, from the homepage to the oldest blog post. Every page, every image address. Then map each old address to exactly one new address, and build a permanent redirect for each pair. Google's guidance on site moves says to redirect old addresses one to one, and it warns against pointing everything at the new homepage. It also says to keep the redirects in place for at least a year, because Google needs the time to move everything the old addresses earned. Timing belongs in the plan too. Google suggests moving during your regular traffic dips, so a guesthouse migrates in the off season rather than the week before December bookings open. If the move includes a new domain name, the yourbusiness.co.za part of the address, the Change of Address tool in Search Console, Google's free reporting service, tells Google directly and keeps forwarding the old domain's standing for 180 days. The plan costs a week of spreadsheet work. Skipping it costs months of missing enquiries, and nobody refunds those.
When staying on your platform is the wiser call
If the platform isn't causing the problem, a migration adds risk without removing anything. The complaints behind most migration briefs, slow rankings, thin traffic, a booking form nobody fills in, tend to travel with the content. Thin pages stay thin on new software, and weak internal links stay weak. A new platform sold as a rankings fix is a new coat of paint on the same shop. Same shop, same problems. A plumber in Manchester wanted a move because his editing screen felt dated; his pages, addresses, and speed scores were all fine, and the rebuild he skipped would have risked all three. We map the wider pattern in our pillar on why your website blocks SEO, and the software is rarely the villain in it.
Three situations argue for staying put. The problem lives in the content, which moves with you. Nobody in the business owns the redirect map, which means addresses will slip. Or your busiest season starts within the next quarter, the worst window for a dip. Fix the content where it stands, and migrate when the platform blocks something you can name: speed you can measure, addresses you can't control, or content you can't export.
Measuring recovery after the move
Recovery from a migration shows up in data within weeks, and the data costs nothing. Search Console shows which searches bring your site up and how many people click through to each page. Before the move, export those numbers: your twenty most-clicked pages, the searches feeding them, and their average positions. After the move, compare the same report against the before-picture, page by page. Google's site-move guidance says a small to medium site takes a few weeks for most pages to move across, and larger sites take longer, so a dip inside the window is normal. Expected, even.
Two signs separate normal from broken. A page still at zero clicks after several weeks points to a redirect missing or aimed at the wrong page, so check its pair on your map. A climbing count of page not found errors, the 404s listed in Search Console's page indexing report, points to addresses the map never covered. Each error is a fixable line in a spreadsheet, not a verdict. A migration without a before-picture leaves you arguing from memory; the export turns a panic into a checklist.
Closing Reflection
The clinic owner in Durban found the cause in the end: two hundred old addresses forwarding to nothing. No competitor had outranked her, and Google had not changed its rules overnight. Her pages were lost in the move, like a box going missing between houses because nobody labelled it. A platform change can be the right call when you can name the reason and you've picked the timing. The site you move to should read as the same business at a better address. Not a stranger Google meets from scratch.
You shouldn't have to choose between a platform you can work with and the rankings you've spent years earning. With Zahavah Studio you won't.
