Why Shopify SEO Requires Specific Expertise
The Technical Specifics of Shopify
Shopify has become the dominant e-commerce platform with 26.2% of global e-commerce sites and a projected revenue exceeding $12 billion in 2026. France is among the fastest-growing markets in terms of merchant adoption.
However, organic search optimization on Shopify presents technical constraints that set it apart from other CMS platforms. The platform imposes a rigid URL structure with /collections/ and /products/ prefixes, generates duplicate pages via URLs like /collections/all/product-name, and offers limited control over the robots.txt file and XML sitemap. The Liquid templating engine also requires specific knowledge to optimize semantic markup and Schema.org structured data.
The GEO Challenge for Shopify E-Commerce Merchants
Beyond traditional SEO, Shopify stores now face a new challenge: GEO (Generative Engine Optimization). In 2025, AI-referred traffic surged by 527%, and brands cited in Google’s AI Overviews receive 35% more organic clicks. For e-commerce merchants, being referenced by generative AIs like ChatGPT or Perplexity is becoming a major growth lever. To explore this topic further, it is useful to consult our guide on what GEO is.

How to Choose the Right Agency for Your Project
Define Your Needs Before Contacting an Agency
Before starting a consultation, it is essential to clarify certain foundational points:
- Primary objective: increase traffic, improve conversion rate, expand into new markets
- Available budget: monthly and over what engagement period
- SEO history: existing site with ranking history, or launch / migration
- GEO ambition: whether or not to integrate an AI visibility strategy
Questions to Ask During the Pre-Sale Process
During discussions with an agency, you should ask targeted questions to assess their actual level of Shopify expertise:
- How many Shopify clients does the agency currently support?
- What quantified results can it present on similar projects?
- How does it handle the technical constraints specific to Shopify (URLs, duplication, Liquid)?
- Does it offer a GEO strategy integrated into traditional SEO?
- What is its reporting process and how frequently?
Shopify SEO optimization is a strategic investment that requires a partner capable of combining technical expertise, data-driven vision, and anticipation of changes in the search landscape. In a context where AI engines are redefining how consumers discover brands, choosing an agency that masters both SEO and GEO provides a lasting competitive advantage.
