How Crawlcore protected revenue in a multi-million e-commerce business during an uncontrolled code change
An e-commerce platform generating 80-100 million PLN in monthly online revenue operates as a complex digital ecosystem. In such an environment, frequent modifications are introduced – from SEO-related changes and checkout optimisations to visual and UX updates.
With every deployment, the SEO team was responsible for verifying whether all critical elements functioned correctly and whether implementation errors had occurred. It was precisely in this context that Crawlcore proved indispensable.
Case study overview
Website type: Large-scale e-commerce platform
Revenue source: Significant share of revenue driven by organic search – double-digit million PLN monthly from SEO
The challenge
During one deployment, due to an unintended error, the canonical tag across all subpages was set to point to the homepage.
This posed a serious risk of:
- deindexation of thousands of URLs,
- loss of organic visibility and traffic,
- significant long-term revenue impact.
The solution
Thanks to Crawlcore, we were able to respond within three hours of the deployment.
In practice:
- The deployment took place at 4:00 AM.
- Crawlcore detected the issue at approximately 5:00 AM.
- By 7:00 AM, the SEO team had informed the client’s technical team.
Because the issue was detected so quickly, the changes were immediately rolled back.
In large e-commerce platforms, where dozens of updates may occur each week, manual verification of every SEO-critical element is practically impossible. This is where Crawlcore becomes essential – monitoring predefined technical components and alerting teams to risks before they affect business performance.
WE REACT BEFORE GOOGLE DOES
Result
Due to rapid detection and response, the faulty implementation was reversed within five hours – before Google reprocessed the incorrect canonical configuration at scale.
This prevented:
- ranking declines,
- traffic loss,
- revenue impact.
This case demonstrates that Crawlcore functions as a “smoke detector” within organisations. It identifies changes in mission-critical SEO areas – including canonical tags, meta elements, H1 headers and indexation status – and enables corrective action before Google registers the issue.

Since I started using Crawlcore, I cannot imagine managing SEO without it. I oversee large-scale websites and multiple projects simultaneously, so I need a solution that immediately alerts me when something goes wrong. Crawlcore does exactly that.
On several occasions, it has quite literally protected my work – detecting critical changes in code, headers or title elements before they impacted Google visibility. This allowed me to react instantly, before any traffic or revenue losses occurred.
