SEO Support for an
E-commerce Migration from WordPress to Shopify

Technical Context: Why This Migration Was Complex

Beyond the sheer scale of the catalog, the project presented several non-standard technical constraints. Shopify’s default limit of 100 variants per product did not meet WBV’s needs – each product had dozens of interdependent configurations. The development team resolved this through metafields, restructuring how product attributes were displayed to separate items by color without breaking SEO connections. It was critical for us that this solution preserved URL structure and internal linking.

On top of that, content on WordPress had been entered incorrectly, which added another layer of complexity to migration preparation. Throughout every stage, we worked in close collaboration with the developers – SEO requirements were built into technical decisions from the start, not added as an afterthought.

Where We Started

From day one, our team made one thing clear: a migration is not just “moving a site.” It is a controlled SEO operation. So the first step was preparing a detailed technical brief for the developers.

Technical Brief for the Development Team

We compiled a comprehensive brief that covered:

• new site architecture
• URL requirements
• preservation of SEO elements
• redirect map (the single most critical element)

The Redirect Map – Foundation of a Successful Migration

A redirect map is a table that matches old URLs to new ones. It tells search engines that a page has moved, not disappeared. Without it: mass 404 errors, lost page authority, ranking drops, and a decline in organic traffic. For a business, that means direct revenue loss.

We gathered URLs from multiple sources: the sitemap, Google Search Console, analytics (high-traffic pages), and the product and category catalog. We then performed not a mechanical, but a semantic mapping:

• product → same product (if it still exists)
• product → closest matching product
• product → category (if the product was removed)
• outdated or junk URLs → relevant sections

This approach is especially important for eCommerce stores with a large number of product variations. The  Shopify development team Web-Systems Solutions implemented a complex 301 redirect system strictly following our map, which cleaned up URLs and preserved the site’s accumulated SEO authority.

Controlling SEO Elements During the Transfer

During migration preparation, we monitored the integrity of all critical SEO elements: content on high-traffic pages, meta titles, meta descriptions, headings, internal link structure, and product counts within listings. The last point was especially important – some listings on WordPress were generated via plugins, and we needed to ensure that categories would not lose completeness or relevance after moving to Shopify.

SEO Optimization and Content Automation

Working alongside the development team, we used the migration as an opportunity for deep optimization:

• Content automation: we implemented automatic generation of Meta Descriptions and ALT tags, enabling scalable SEO across hundreds of products and stronger visibility in Google Images.
• Rich Snippets: Schema.org markup was implemented for product variations and FAQ blocks, improving search result appearance and CTR.
• Dynamic H1 tags: configured with product color names included, expanding coverage of long-tail search queries.

Working with the Development Team

We did not stop at handing over a brief. Throughout the project, we stayed in constant communication with the development team – verifying redirect implementation, monitoring URL structure, and tracking the accuracy of execution. In practice, the SEO + project management + development connection functioned as a single unit.

On the development side, Web-Systems Solutions delivered a full UX rebuild alongside the technical migration: 90+ hours of mobile interface work, redesigned product cards, hover effects, and complex interdependent variant logic. We ensured that every UX decision reinforced, rather than conflicted with, the SEO architecture.

Core Web Vitals – A Joint Effort

Core Web Vitals had been a persistent problem on WordPress. Both teams addressed this together: developers optimized the DOM, fixed image attributes, and rebuilt the product gallery. After the migration, underperforming pages effectively disappeared, and site performance was no longer a systemic risk. Google explicitly states that Core Web Vitals are part of page experience signals and factor into rankings.

After the Migration

After the migration went live, we did not stop at launch. We waited for reindexation (Google continued to show old WordPress URLs in Search Console for some time), ran benchmark measurements, and tracked how search visibility evolved. This allowed us to evaluate the real impact of the migration based on data, not impressions.

Results

The outcome exceeded expectations – we did not just hold rankings. The migration was completed without any ranking drop, and after full reindexation the site showed consistent growth across key commercial clusters.

• “Single vanity” cluster reached top 10, with some queries breaking into top 5 (previously this cluster had resisted promotion for a long time)

• Commercial “double vanity” queries also reached top 10

• +52.43% organic traffic growth (final comparison: March–April 2025 vs 2026)

• +88% total revenue growth
• +87.34% increase in conversions
• +81.68% improvement in conversion rate
• 26 target keywords ranked in the top 10 on Google US
• 9,000% average ROAS across the strategy

Our Takeaway

A site migration is both a risk and an opportunity. Without SEO support: traffic drops, rankings fall, revenue declines. Done right: accumulated SEO authority is preserved, visibility improves, and business growth accelerates.

This project proved that when an SEO team and developers operate as a single system from day one, migration stops being a threat and becomes a competitive advantage.

Why Clients Choose Us

This case reflects our approach well. We do not simply “turn on SEO at launch” or limit ourselves to recommendations. We run the migration as a full project: we plan, verify, communicate with the development team, manage the details, and take responsibility for the outcome. That is why our clients end up with not just a new site on a new platform, but a site that preserves and strengthens its search performance.

Planning a Migration?

If you are planning to migrate to Shopify or another platform – especially with a large catalog, eCommerce scale, and thousands of pages – SEO support is not optional. We will:

• build your redirect map
• oversee the development process
• protect your traffic and rankings
