🔥 KEY CASE METRICS:
• France expansion campaigns ROAS: 0.
• Google Ads spend without a single add-to-cart: €1,654.33.
• Pages removed from the index by Google due to a code error: 227,106 pages.
• For comparison, home market (Estonia) organic traffic add-to-cart rate: 16.0%.

BUSINESS BACKGROUND AND MARKET CONTRAST

In modern e-commerce, expanding to foreign markets is an enticing yet technically risky step. This case study analyzes the expansion into the French market by one of the Nordic and Baltic region’s leading electrical engineering and industrial automation B2B wholesalers.

The company’s strategy focuses on serving specific target groups — such as industrial enterprises, designers, and panel builders — through an extensive product portfolio. In its domestic market, it has achieved a position where precise keyword targeting is reflected in results: the organic traffic add-to-cart rate is an impressive 16.0%, confirming the platform’s technical maturity and user experience quality.

Simultaneously, the platform generates significant organic revenue in several European markets (including Belgium, Portugal, Slovenia) without additional media investment. In contrast, the resources directed at conquering the French market — both Google Ads ad spend and development activities — proved to be a complete strategic misfire: campaign ROAS was a disastrous 0, meaning 100% of the budget was essentially burned with no business outcome.

1. DIAGNOSIS: THE REAL COST OF MISSING SEO AND CRO SYNERGY

A deep-dive audit and marketing channel efficiency analysis conducted by SECRO Solutions identified two critical errors that completely burned the campaign budgets:

  • Singapore robot traffic pressure: A detailed audit of the GA4 platform revealed that over half of the 10,150 visits to the French domain consisted of anonymous spam traffic originating geographically from Singapore.
  • Analytics blind spot (measurement error): The e-commerce setup of the French domain lacked functioning purchase and transaction conversion tracking. Because Google Ads machine learning algorithms lacked feedback regarding real purchases, the system was unable to target ads and continued generating worthless traffic.

2. TECHNICAL DETECTIVE WORK: THE CANONICAL “SHOWSTOPPER”

The audit identified a critical technical barrier that rendered the French-language platform invisible to search engines – the core of the problem lay in a single faulty line of code:

  • Cross-canonical tag conflict: The canonical references (<link rel=”canonical”>) of the French domain directed bots to the Estonian-language domain in both the source code and the rendered layer.
  • Technical impact on indexing: The canonical tag acts as a strict guideline for Google (although Google may ignore it in exceptional cases) to prefer the referenced address. As a result, all French content was classified as duplicate content, leading to the removal of 227,106 potential landing pages from the index.
  • Client-side dynamic loading: Website content was initially displayed in English upon the first visit, and the French language was only activated after a JavaScript reload. This created linguistic conflicts where search bots recorded English data under a French flag.

3. GENERATIVE ENGINE OPTIMIZATION (GEO): WHY CHATGPT DOES NOT RECOMMEND YOU?

Modern search optimization also encompasses influencing AI assistants (ChatGPT, Perplexity, Microsoft Copilot, Google AI Overviews).

Since OpenAI and Microsoft Copilot use the Bing search engine index to aggregate their responses, technical SEO and canonical correctness are the foundation of artificial intelligence visibility. Our measurements showed a direct correlation between technical code errors and AI citations:

  • Estonian main operations (home market): A properly indexed local platform achieved more than 5,800 impressions in the last quarter via Google AI Overviews, with artificial intelligence actively recommending specific wholesale articles and licensing solutions. By comparison, Bing AI stably cited the product portfolio, but in a more modest volume, generating ten citations during the short test period.
  • French domain critical vacuum: The statistics of mentions and impressions in Bing AI and ChatGPT systems remained at zero. Technical flaws in the code prevented AI crawlers from correctly analyzing the platform, resulting in the brand’s visibility being completely removed from French market LLM recommendations.

4. STRATEGIC LESSONS AND SECRO RECOMMENDATIONS

The analysis of this case confirms that cross-border e-commerce scaling is not limited to localization alone, but uncompromisingly requires a precise technical architecture:

  • Technical SEO as a guarantee of stability: Even a marginal error in a line of code can devalue large-scale development investments, making the platform de facto inaccessible to search engines.
  • Budget optimization through CRO: Implementing Google Ads investments without precise conversion tracking and bot protection is a strategically blind activity where machine learning, in the absence of feedback, will prioritize worthless bot traffic.
  • LLM models and AI visibility logic: Artificial intelligence assistants (e.g. ChatGPT) rely on traditional indexing rules; therefore, if the platform is invisible to Google or Bing, the brand also lacks authority in AI recommendations.

SECRO Solutions formulated a strategic action plan for the client’s technical partner, focusing on the correction of canonical tags (self-canonical), the implementation of server-side rendering (SSR), and the complete validation of the GA4 e-commerce data layer.

The elimination of these technical barriers is a mandatory prerequisite for realizing the organic potential of the French market and restoring the profitability of advertising investments. The synergistic application of SEO and CRO is the only method that ensures the direct contribution of technical details to the company’s business expansion.
