Shop Migration & Relaunch SEO

Relaunch, replatforming or new markets: I guide your shop migration so rankings and revenue stay intact. And if the relaunch already happened and traffic dropped, I find the cause and get your visibility back.

The relaunch is done and the traffic is gone

Most pages about relaunches address companies whose go-live is still ahead of them. If the damage has already happened, that does not help you much. That is why this section comes first: it is for everyone whose relaunch is behind them and whose numbers have not been right since.

Do you recognise any of these patterns?

Traffic drops right on the go-live day

A sharp drop exactly on the launch date almost always points to missing redirects or an indexing block carried over from staging. This is the variant that can be fixed fastest.

Rankings that were stable for years have vanished completely

When established positions do not slip but disappear from the index entirely, the old URLs lead nowhere. The authority you built never reaches the new destination.

Search Console suddenly reports hundreds of 404 errors

Every dead URL was once a ranking page or a backlink target. The 404 report is the most concrete list of what the relaunch cost you.

Important pages are no longer indexed

A noindex left over from staging or a blocking robots.txt removes entire sections from search. Technically trivial, devastating in effect, fixed within hours.

The decline came gradually, weeks after the relaunch

Not every drop is visible immediately. Google often detects structural problems only after several crawling cycles, and visibility then declines step by step over weeks.

Traffic has not recovered on its own for months

This is the most important point: structural damage does not heal. Google removes dead URLs from the index permanently, and the authority of the old addresses decays over time. Waiting means losing more.

Rule of thumb: if traffic has not recovered three months after the relaunch, it will not recover without intervention. At that point the situation is not a transition, it is the new normal.

Find the cause before taking action

The most common mistake after a drop is to respond immediately with more content or link building. Both cost money and fix none of the typical relaunch problems. So before any action comes the question of which possible cause actually applies. Six checks usually settle it:

  • Redirects: does every old URL point via 301 to a meaningful new target, or do entire directories land on the homepage?
  • Indexing: did noindex directives or robots.txt blocks from staging go live with the site?
  • Content: were ranking pages deleted, merged or heavily shortened during the relaunch?
  • Canonicals: do the canonical tags point to the correct version, or still to the old domain or a staging URL?
  • Backlinks: do your strongest external links still reach live targets, or do they lead nowhere?
  • Attribution: does the drop coincide with a documented Google update, or exactly with the go-live date?

The basis is always real data: Search Console before and after the relaunch, a full crawl of the new site, the old URL list from an archive or backup, and the backlink profile. Only once it is clear which of these points caused the damage does any action make sense.

Points two to four fall under technical SEO. That page explains in detail how indexing, crawling and rendering interact, and why a site can stay invisible despite good content.

The risk of a relaunch

With every shop relaunch or replatforming, URLs, structure and templates change. Without proper SEO support, you lose exactly the rankings you worked years for. The typical post-launch drop is avoidable when the migration is planned from an SEO perspective from the start.

With a clean 301 redirect concept, visibility is preserved and keeps growing. Without a concept, the typical post-launch drop follows.

The most common causes of the drop are always the same: missing or faulty 301 redirects, hundreds of suddenly created 404 error pages, lost backlinks pointing into the void, and a sitemap that still serves the old URLs. Each of these costs rankings, and together they create the visibility loss that you see immediately in any SEO tool.

A replatforming from practice

How quickly a relaunch becomes a pitfall is shown by a switch from Shopware to Shopify, where the shop was migrated over a single weekend. Around 50,000 indexed URLs became roughly 5,000 overnight, a deliberate consolidation that is dangerous without a complete redirect matrix.

From around 50,000 to roughly 5,000 URLs over one weekend. Every URL that disappears needs a clean 301 target, otherwise rankings and backlinks are lost.

This is exactly where success is decided: if every old URL is cleanly redirected to its new target and the shop is consistently supported after launch, visibility stays stable. If that care is missing, the drop in the visibility curves is only a matter of time. That's why my support does not end on go-live day, but continues through the crucial weeks afterwards.

Migration without ranking loss

My proven roadmap for Shopify migrations and relaunches, in five steps:

1

Secure the status quo

A complete crawl of the old shop, an indexing and ranking snapshot, and a record of all existing URLs and backlinks.

2

URL & 301 plan

Mapping every old URL to its new target and a complete 301 redirect matrix, so link equity and rankings carry over.

3

Technical SEO

A review of canonicals, robots, sitemaps, structured data and load time on the new platform before go-live.

4

Staging sign-off

A check of the new shop on staging, testing the redirects and a sign-off checklist before going live.

5

Launch & monitoring

Support on go-live day, 404 monitoring, checking indexing and rankings in the weeks afterwards, and quick adjustments.

Internationalizing your shop

Want to expand into new markets? For Google to serve the right language version in the right country, you need a clean technical foundation:

  • hreflang setup for every language and country version, without conflicts and self-reference errors
  • Domain strategy: ccTLD, subdomain or subdirectory, weighed against resources and target markets
  • Translation SEO instead of pure word-for-word translation, with local keyword research per market
  • Geo-targeting in Search Console and consistent internal linking per language region
  • Avoiding duplicate content between language variants and correct canonicals
With Shopify in particular, there are typical pitfalls around markets and languages. I know them and set everything up to be search-engine-safe from the start.

PURELEI: growth on Shopify instead of a drop

The work with the jewelry brand PURELEI shows that a cleanly set up Shopify shop can grow strongly instead of dropping. Instead of a relaunch drop, organic visibility climbed continuously, and the SISTRIX index has more than doubled since October 2024.

Frequently asked questions about relaunches and traffic loss

My traffic dropped after the relaunch and is not recovering. What causes that?

In the vast majority of cases: missing or incorrect 301 redirects, an indexing block carried over from staging, deleted content, or wrongly set canonicals. These errors do not heal on their own, because Google removes dead URLs from the index permanently. The difference between a drop that recovers and one that stays is almost always whether the cause was found and fixed.

Can a traffic drop still be fixed months after the relaunch?

Yes. Redirects still work retroactively, deleted content can be restored, and indexing blocks are fixed within hours. The longer the situation persists, however, the more link equity has drained away and the longer the recovery takes. Four months is very fixable, but it needs a proper root cause analysis rather than treating symptoms.

How long does it take for rankings to recover after a fix?

Technical errors such as a noindex block take effect within days to a few weeks after the recrawl. Redirects added later usually need four to eight weeks until link equity arrives again. For larger structural damage, expect three to six months until full recovery.

How do I tell whether the relaunch or a Google update is to blame?

By the pattern of the decline. Relaunch damage starts on the go-live day or grows over the following crawling cycles, and hits entire URL groups evenly. An algorithm update hits by topic, not by structure, and falls on a documented update date. Telling them apart is the first step of any analysis, because the two require completely different measures.

Do you also work with the agency that did the relaunch?

Yes, and that is usually the fastest route. I provide the diagnosis and a concrete implementation list, your existing team or agency does the work. This is not about assigning blame, it is about getting visibility back.

What does migration support cost?

Support starts from 2,500 EUR, and from 4,000 EUR for 10,000 URLs or more. A pure root cause analysis after a relaunch that already happened is leaner and is quoted based on effort. We agree the scope up front, transparently and with no hidden items.
