Mercialys, a major player in retail real estate, turned to Junto to strengthen the visibility of its shopping centers and structure their SEO presence.

Mercialys is deploying an innovative digital strategy in the world of shopping centers.
With the launch of e-commerce subdomains dedicated to each center, the challenge was to structure SEO without weakening the main domain's authority. With technical and semantic support, the brand generated fast, readable SEO traffic growth on pages that had previously been underused.
Structuring high-performing multisite SEO
To address each center's specific needs, Junto put a tailor-made SEO strategy in place: technical audit, identification of priority pages, URL structure overhaul, and semantic siloing. Link building and precise performance monitoring quickly improved the organic visibility of the entire shopping center portfolio.

Rolling out a multisite SEO strategy
From the start of the partnership, Junto implemented a dedicated SEO strategy to address Mercialys's multisite challenges. The goal: prevent the centers' e-commerce subdomains from hurting the main domain's authority. Extensive semantic and technical structuring work was carried out to maximize each entity's indexing and SEO effectiveness.
Improving performance on local queries
With each center now having its own catalog, Junto's support made it possible to target local search intent much more precisely. This precise positioning led to a significant increase in SEO traffic while supporting transactional performance.
Aligning SEO across sites and subdomains
Through priority page analysis, technical redirect management, and rewritten site structures, Junto enabled Mercialys to deploy a coherent SEO logic across its commerce sites and informational spaces. The result: better overall rankings, with no dilution of authority.
