Navigating SEO After a Major Site Migration: Lessons from a Community Discussion

Hey there, fellow Shopify merchants and store operators! Ever felt like your SEO performance took an unexpected nosedive despite your best efforts? You're not alone. I recently saw a fascinating community discussion highlighting the complexities of technical SEO, especially after a major site migration.

The original poster shared a tough situation: their Italian e-commerce site, migrated from a subdomain (it.hello-random-site.com) to a subfolder (hello-random-site.com/it), saw its Googlebot crawl budget plummet by 78%. SERP rankings dropped significantly, averaging page 7.5 for key terms. The kicker? A long-standing partner had 24,000 backlinks pointing to the old subdomain URLs. The poster suspected these 'wrong' links were causing massive crawl delays and budget waste.

Is It Just the Backlinks?

It's tempting to blame a huge number of broken backlinks. However, as one community member wisely pointed out, 24,000 links from a single domain are rarely the sole issue. Their advice? First, verify redirects, internal linking, crawl logs, and indexation status. This is a vital first step for any Shopify store owner facing similar issues – always check your own house first!

Another respondent emphasized the bigger picture: Google treats subdomains as independent entities, while a subfolder is part of the main domain. This fundamental shift necessitates a complete migration check, going far beyond just backlinks. The original poster confirmed they'd followed best practices for their 1:1 transfer, yet the site had "essentially tanked." They acknowledged a content gap but prioritized the significant crawl budget waste.

Diving Deeper: Core Web Vitals and Performance

When initial checks don't reveal the cause, dig deeper. A community member suggested looking at Google core updates and, crucially, Core Web Vitals. Bad website performance impacts SEO. The original poster admitted their mobile site was "a bit slow." This is a common Shopify challenge – balancing rich experiences with fast load times.

What made it puzzling was that their other regional sites (French, US, Mexican), also on subfolders, were performing exceptionally well (average SERP 1.4). This disparity suggested the problem was specific to the Italian site. A deep dive per market was recommended, and for the Italian site, the original poster confirmed, it was "clearly everything," indicating a systemic issue.

Key Takeaways for Shopify Merchants

This discussion offers critical lessons for Shopify store owners:

• Plan Migrations Meticulously: A subdomain to subfolder migration requires thorough planning for redirects, internal linking, canonical tags, and continuous monitoring.
• Look Beyond Backlinks: Severe SEO drops post-migration are rarely just about external links. Prioritize investigating internal linking, indexation, crawl logs, and overall site health.
• Prioritize Performance: Core Web Vitals and mobile speed are non-negotiable. Slow loading times impact crawl budget and rankings.
• Address Content Gaps: A technically sound site still needs strong, relevant content for long-term SEO health.
• Conduct Market-Specific Analysis: For multiple regional stores, pinpoint unique issues with deep-dive data, don't assume universal problems.
