- The technical and structural steps Leftfield uses to ensure a search-ready launch
- How to turn migration into an opportunity to amplify discoverability rather than risking it
The hidden risk of migration: SEO degradation
When brands migrate to Shopify, the focus is often on:
- design
- UX
- product data
- checkout
- integrations
SEO is usually treated as an afterthought.
But ignoring SEO during migration is one of the fastest ways to:
- lose rankings
- lose organic traffic
- break content discoverability
- weaken brand visibility across AI and search engines
Leftfield specialise in preventing this.
Their approach ensures your Shopify store goes live search-ready, AI-readable, and structured for long-term visibility.
Why SEO & GEO cannot be “fixed Later”
Most sites that come to Leftfield haven’t been fully optimised — even before migration.
Pausing SEO during a rebuild is a common mistake. Instead, migration should be treated as the perfect moment to:
- rebuild technical foundations
- fix legacy issues
- clean up URL structures
- improve information architecture
- strengthen entity and topical signals
- adapt for AI-driven search results (SGE, Copilot, Anthropic, OpenAI)
This ensures the new site doesn’t just retain visibility, it gains visibility.
Leftfield’s end-to-end SEO & GEO migration framework
Their structured approach reduces migration risk and boosts performance.
1. Audit & Benchmark Before the Move
Leftfield perform a full crawl of the existing site to identify:
- every URL
- performance metrics
- link equity
- SEO issues
- content gaps
- missing entity / brand signals (vital for SGE + AI engines)
This becomes the baseline for evaluating post-migration success.
2. Strategic URL & Redirect Mapping
Every legacy URL gets a specific destination.
No catch-all redirects.
No lazy routing.
Accurate mapping preserves:
- link equity
- user journeys
- ranking stability
This step alone protects years of organic value.
3. GEO Enhancement for AI Discovery
Leftfield build structures that make the site more understandable for:
- Google’s SGE
- Bing Copilot
- AI answer engines
- LLM-based retrieval systems
This includes:
- entity-based schema
- structured data frameworks
- improved internal linking
- semantic clarity
- topical reinforcement
It’s SEO, modernised for AI.
Technical SEO Built Into the Shopify Build
Leftfield collaborate directly with development teams to ensure:
- correct canonicalisation
- schema markup
- metadata structure
- performance optimisation
- crawl-efficient site architecture
- mobile-first standards
This ensures the Shopify store:
- loads fast
- indexes correctly
- ranks confidently
- becomes AI-readable and context-rich
Multi-crawl pre-launch testing
Leftfield run multiple crawls of the staging site before launch to validate:
- full redirect behaviour
- internal linking
- metadata
- structured data
- canonical tags
- missing pages
- crawl traps
Simultaneously, they optimise:
- speed
- image compression
- code efficiency
- mobile UX
The goal: eliminate risk before the public ever sees the site.
Launch, monitoring & post-migration optimisation
After going live, Leftfield:
- monitor redirects
- review indexing in Google Search Console + Bing Webmaster Tools
- submit XML sitemaps
- validate structured data
- track crawl activity
- react to any early ranking volatility
- optimise based on live data signals
This ensures the new site not only avoids SEO damage, it outperforms the old one.
Why This Approach Works
- SEO & GEO are embedded from day one
- Traffic is protected through accurate, tested redirects
- AI-driven search visibility increases through entity structuring
- Technical quality is validated before launch
- The new Shopify store has stronger search identity than the legacy platform
Migration becomes an upgrade, not a risk to manage.
