Ecommerce SEO Migration Agency
We specialise in SEO migration for ecommerce brands, protecting organic traffic and rankings through every stage of your platform move. Migrate to Shopify from Magento, Adobe Commerce, or WooCommerce with a structured SEO migration strategy built around your specific store, timeline and risk profile.
Protecting your rankings through a platform migration
Development and SEO need to work together throughout.
A platform migration is one of the highest-risk events in an ecommerce brand's digital life. Without a clear SEO migration plan you can lose up to 50% of your organic traffic overnight: traffic that took years to build.
When development and SEO are handled separately during a migration, that's where rankings get lost. At Unified, both teams work together throughout, so when we move your store, from WooCommerce or Adobe Commerce to Shopify Plus, for example, canonical tags, redirect chains, and structured data are considered at every stage of the build. We're one of very few UK agencies with certified expertise across both the platform you're leaving and the one you're moving to.

Our SEO migration services
Pre-migration SEO audit
Full crawl of your existing site: ranking pages, backlink profile, URL structure, canonical issues, and structured data. We benchmark everything before we touch a line of code.
URL mapping & redirect strategy
Every redirect is tested before go-live. We check each one individually to make sure the chain is clean, the destination is correct, and nothing is looped or broken.
Technical SEO configuration
Canonical tags, XML sitemaps, robots.txt, hreflang for international stores, structured data. Platform-specific issues addressed at build stage.
Content & metadata migration
Page titles, meta descriptions, H1s, and schema markup migrated and reviewed. Every page reviewed for SEO value before and after.
Post-launch monitoring
30-day intensive monitoring after go-live. We watch Search Console, crawl errors, and ranking movements daily. If something drops, we're on it the same day.
International SEO & Shopify Markets
Migrating a multi-region store? We handle hreflang implementation, Shopify Markets configuration, and international URL structure to ensure each market lands correctly.

FAQs
Will I lose my Google rankings when I migrate?
Any loss of rankings can be minimised if migration is handled correctly. A great migration can be so seamless that no rankings are lost at all. The primary causes of ranking loss are broken redirect chains, missing canonical tags, lost structured data, and changes to URL structure without proper mapping. We address all of these before your new site goes live, and monitor Search Console daily in the 30 days after launch.
How long does an ecommerce migration take?
A typical Magento to Shopify Plus migration takes 10-16 weeks from discovery to go-live, depending on catalogue complexity, the number of integrations, and whether a redesign is included. We don't rush migrations. A botched go-live costs more to fix than a careful build.
Can you migrate a large product catalogue?
Yes. We've migrated catalogues ranging from a few hundred to tens of thousands of SKUs. For large catalogues, we typically use Akeneo (PIM) to manage the data migration cleanly, ensuring product data, variants, and attributes transfer without the mess that comes from direct platform-to-platform exports.
Do you handle the SEO migration as part of the build, or is it a separate project?
It's integrated into the build. This is one of the main reasons clients choose Unified over other agencies. We don't hand off between a dev team and an SEO team; the same team does both. SEO decisions are made at the right point in the build process, not retrospectively after the site is live.
What does migration cost?
Migration costs vary based on catalogue size, integration complexity, whether a redesign is included, and the source platform. A scoped Magento to Shopify Plus migration with full SEO management typically starts from £25,000. We'll scope your project specifically in a free discovery call.
We're on Adobe Commerce. Can you still help us?
Yes. Adobe Commerce is one of our core platforms. We're both Adobe Commerce partners and Hyvä-certified, so we can either migrate your store to Shopify Plus, or improve your Adobe Commerce store with a Hyvä frontend migration that dramatically improves performance without a full replatform.
