SEO migration planning before your Shopify build begins

The biggest migration mistakes usually happen before the new website launches.

URL structures change, important pages disappear, content gets rewritten, internal links move and collection architecture is redesigned without understanding which parts of the existing website already drive organic performance.

We benchmark the existing site before development is complete so search data can inform the new Shopify architecture from the outset.

Our pre-migration work can include:

• Organic traffic and revenue benchmarking

• Keyword and landing-page performance

• Existing URL inventory

• Backlink analysis

• Redirect exports and legacy redirects

• Site architecture review

• Content and metadata benchmarking

• Technical SEO crawling

Shopify information architecture and URL planning

A Shopify migration should not automatically recreate the structure of the old website.

Replatforming creates an opportunity to improve how collections, products and supporting content are organised around real customer search demand.

We combine existing organic performance with keyword and competitor research to identify what should be preserved, consolidated, expanded or rebuilt.

That means protecting valuable search equity while improving the foundations for future organic growth.

Shopify URL mapping and redirect strategy

Shopify often uses different URL structures from platforms such as Magento, WooCommerce, BigCommerce and custom ecommerce systems.

Every commercially valuable legacy URL needs to be assessed and mapped to the most relevant destination on the new Shopify store.

We create and QA redirect mappings to minimise unnecessary 404 errors, preserve existing authority and ensure users and search engines reach the correct replacement pages.

Our redirect process also looks for:

• Redirect chains

• Redirect loops

• Important backlink destinations

• Removed products and collections

• Changed category architecture

• Existing legacy redirects that still need preserving

For smaller redirect projects, you can also use our free URL Redirect Mapper.

Technical SEO checks for Shopify migrations

Redirects are only one part of a successful Shopify SEO migration.

We compare the new Shopify build against the legacy website to identify technical changes that could affect search visibility.

Depending on the project, migration QA can cover:

• Canonical tags

• Robots directives

• XML sitemaps

• Internal linking

• Metadata and headings

• Structured data

• Product and collection indexability

• Faceted navigation

• Pagination

• JavaScript rendering

• Core Web Vitals

• Hreflang and international targeting

• Google Merchant Center feeds

• GA4, GTM and conversion tracking

Our Technical Architecture system supports the wider technical requirements behind complex ecommerce migrations.

Staging QA before launch

We review the Shopify staging environment before launch so issues can be resolved before search engines encounter the new site.

This includes crawling the new store, comparing key templates and landing pages against the existing website and validating agreed migration requirements.

Typical staging checks include:

• URL structure

• Redirect implementation

• Internal links

• 404 errors

• Canonicals

• Indexation directives

• Metadata

• Content transfer

• Structured data

• Navigation and crawl depth

The objective is to resolve avoidable problems before launch rather than discovering them in Google Search Console several weeks later.

Shopify launch support

Launch day is when the migration moves from planning into reality.

We work through the critical SEO checks immediately after the new Shopify store goes live.

This can include:

• Validating priority redirects

• Crawling the live website

• Checking robots.txt and indexability

• Reviewing canonical tags

• Submitting updated XML sitemaps

• Checking Search Console

• Validating analytics and conversion tracking

• Checking critical product and collection templates

Post-launch Shopify SEO monitoring

A migration is not finished when the new website launches.

Search engines need time to recrawl and process the new structure, and some volatility can occur during that transition.

We monitor organic performance against the pre-launch benchmark so we can distinguish normal movement from issues that require intervention.

Post-launch monitoring can include:

• Priority keyword rankings

• Organic traffic and revenue

• Indexation

• Crawl errors

• 404 URLs

• Redirect behaviour

• Collection and product performance

• Core Web Vitals

• Search Console coverage

Migrating from Magento to Shopify

Magento to Shopify migrations often involve major changes to URL structures, product architecture, category pages, faceted navigation and technical implementation.

We identify which Magento URLs and search signals need to be preserved while helping shape a cleaner Shopify structure for future growth.

Particular attention is given to category mapping, product URLs, legacy redirects, filters, canonical behaviour and any international architecture being replaced.

Migrating from WooCommerce to Shopify

WooCommerce migrations can involve changes across products, categories, blog content, WordPress URL structures and plugins that previously controlled important technical SEO functionality.

We ensure commercially important WordPress and WooCommerce URLs are accounted for and that equivalent SEO functionality is correctly implemented within Shopify.

Migrating from BigCommerce to Shopify

Moving from BigCommerce to Shopify can change product, category and filter structures while introducing different technical behaviour around canonicals, structured data and international markets.

We map those differences before launch so the migration does not unnecessarily sacrifice existing organic equity.

Custom ecommerce platforms to Shopify

Custom ecommerce migrations can be particularly complex because existing functionality, URL structures and technical behaviour may not map directly into Shopify.

We work alongside developers to understand what search engines currently see, identify the commercially valuable elements worth preserving and translate those requirements into the new Shopify architecture.

Shopify redesigns and theme migrations

You do not need to change platforms for SEO migration risk to exist.

A major Shopify redesign or theme change can affect navigation, internal linking, headings, structured data, page speed, JavaScript rendering and content even when many URLs remain unchanged.

We therefore treat significant Shopify redesigns with the same migration discipline: benchmark first, QA before launch and monitor afterwards.

Shopify Plus migrations

Larger Shopify Plus migrations often involve more markets, integrations, custom functionality and stakeholders.

We provide the SEO strategy and QA layer alongside ecommerce, design and development teams so organic requirements remain visible throughout the project rather than becoming a launch-week task.

International Shopify migrations

International migrations introduce another layer of complexity.

Moving to Shopify Markets, consolidating regional stores or changing international URL structures can affect rankings across multiple countries at the same time.

We plan international URL mapping, hreflang, localisation, canonicals and regional indexing alongside the wider migration.

Can you migrate to Shopify without losing SEO?

No agency can credibly guarantee zero ranking movement during a major website migration.

What can be controlled is the quality of the planning.

Most significant migration losses are caused by avoidable issues such as missing redirects, lost content, changed architecture, incorrect canonicals, accidental noindex directives or technical problems that were not identified before launch.

Our job is to identify and mitigate those risks systematically while giving the new Shopify store stronger foundations for future growth.

Our Shopify SEO migration process

1. Benchmark

Capture existing rankings, traffic, revenue, URLs, backlinks and technical performance before anything changes.

2. Plan

Use organic search data to inform the new Shopify architecture, collections, content and migration requirements.

3. Map

Create a comprehensive redirect plan connecting important legacy URLs with their most relevant Shopify destinations.

4. QA

Crawl and review the Shopify staging environment before launch, comparing critical SEO signals against the existing website.

5. Launch

Validate redirects, indexability, tracking, sitemaps and priority templates as soon as the new store goes live.

6. Monitor

Track organic performance against the original benchmark and investigate unexpected changes quickly.

Shopify migrations built around commercial performance

The goal of a migration is not simply to preserve rankings.

A new Shopify store should create stronger foundations for future growth.

That means measuring the transition through commercial metrics such as:

• Organic revenue

• Transactions

• Conversion rate

• Priority collection visibility

• Product performance

• Non-branded organic traffic

• New customer acquisition

• International market performance
