Changing platforms is one of the most common worries store owners have: "I’ll move my store and lose all my Google traffic". The good news – migration doesn’t have to cost you rankings, as long as it’s planned technically before you switch the store over. We’re writing about this as a team that migrates online stores between platforms – not as an SEO agency selling rankings. We’ll show you what really happens to your rankings, how to protect your traffic and who is responsible for what along the way.
A drop in rankings after migration – what to really expect
Let’s start by setting expectations honestly. A temporary drop in rankings after migration is normal. When your URLs change, Google has to reindex the store – visit the new addresses, recognise the structure, assign rankings. That doesn’t happen overnight.
The key word is "temporary". Short-term fluctuations are predictable and pass, as long as the SEO migration plan – redirects, URL mapping, structure – is ready before you switch the store over. From our projects we see a clear difference between a planned migration and one done on the fly.
The biggest risk arises when a store is switched over with no redirect plan. Old addresses return errors, Google loses its path to the content, and recovering rankings takes far longer. So the point isn’t to avoid any drop at all – it’s to make it shallow and short rather than deep and lasting.
Before you start – realistic scope and a pre-migration audit
SEO migration doesn’t start when you switch the platform. It starts with a plan and an inventory.
The first myth to bust: the 1:1 migration. Clients often expect the new platform to recreate the old store point by point. In practice, data structures and URLs don’t fully overlap between platforms – there are always differences, and they need to be named at the start, not midway through. That applies to URLs too, and so directly to your SEO.
Before anything gets switched over, an audit of the current store is needed. It covers:
- a list of URLs – all products, categories, pages and blog posts,
- identifying the strongest pages – the ones that generate organic traffic and rankings; these need the most careful redirects,
- an assessment of data quality – in older stores, product data often builds up manually over the years and can be outdated, inconsistent or incomplete (missing images, descriptions or attributes).
Checking all of this before the start gives you a clear scope of work upfront, with no surprises along the way.
This audit is not a formality – it’s exactly what keeps the cost and the timeline predictable.
Technical foundation: 301s, URL map, sitemap and Google Search Console
This is the technical part of the migration. Here’s what actually gets done so that traffic from old addresses reaches the new ones.
URL map. Before the switch, a table of "old address – new address" is prepared. A product leads to its matching product, a category to its category. This isn’t work that can be done after the fact – it has to be ready before launch.
301 redirects. Every old address gets a permanent 301 redirect to its new counterpart. This is the most important mechanism in the whole SEO migration – a 301 redirect passes most of the "authority" the old address built up on to the new one. Thanks to that, rankings and links pointing to old pages don’t go to waste.
What to watch out for in practice:
- Don’t redirect everything to the homepage. Google treats a bulk redirect to the homepage as a so-called soft 404 – a signal that the content is gone. That does more harm than good. Each address should land on the new address that matches it in content.
- Avoid redirect chains – address A to B, then B to C. Every extra hop is a loss and slows processing down.
- Keep the URL structure wherever you can. The fewer changes to addresses, the lower the risk.
Sitemap and Google Search Console. After the switch, a new sitemap (sitemap.xml) is generated and submitted in Google Search Console. In the first few weeks it’s worth monitoring the indexing report – catching 404s and redirect errors before they can do any damage. For a full domain change, a change of address is set in Search Console as well.
And one more thing about staying realistic: reindexing a larger store is a process measured in weeks, not a single day. Google works through a large product catalogue gradually. Patience and monitoring during that period matter just as much as the redirect setup itself.
Who’s responsible for what: technical migration vs SEO agency
Here’s the distinction usually missing from articles about migration. SEO migration requires two roles, not one.
The technical migration layer covers:
- migrating data between platforms,
- preparing the URL map and implementing 301 redirects,
- submitting the new sitemap and technical monitoring after the switch,
- transferring the configuration of your supplier integrations, if you have them (more on that in the next section).
An SEO agency or your store’s SEO specialist is responsible for the strategic layer:
- keyword strategy and intent mapping,
- overseeing rankings and traffic after the migration,
- decisions about content structure and further optimisation.
It’s worth knowing where one role ends and the other begins – especially when you’re planning a migration. If you have an SEO specialist, bring them in at the planning stage, not after the store has been switched over.
Do you have supplier integrations? You won’t be setting them up from scratch
If you run dropshipping, changing platforms raises a question most migration guides stay silent about: what happens to your supplier integrations.
Let’s separate two situations. If you’re migrating a store and don’t have supplier integrations with us – we move what you want to take to the new platform: products, customers and orders. We cover what migrates easily and what causes problems in more depth in a separate article on store migration. Integrations are a separate topic in that case.
If you already have supplier integrations with us, there’s good news: we don’t set them up from scratch on the new store. Our integrator is platform-independent, so we transfer the configuration – the settings that already work carry over to the new platform. You don’t roll out each supplier from the beginning, and from day one your new store has up-to-date stock levels, prices and products.
Summary
Migrating your store doesn’t have to cost you rankings in Google. A temporary drop is normal and passes, as long as the technical side is prepared in advance: URL map, 301 redirects, a new sitemap submitted in Search Console and monitoring in the first few weeks. Separate the roles – technical migration is on our side, strategy and rankings sit with the SEO agency. And if you have supplier integrations with us – during migration we transfer their configuration to the new store instead of setting them up from scratch.
