Nertis

Based in Fontaine-Simon, France, Nertis is an independent consultancy built around a single practitioner offering fractional strategic leadership to B2B companies. Rather than positioning itself as a full-service agency, it presents an alternative to hiring a full-time CMO or replacing an existing agency, working with organizations that need embedded strategic input across acquisition, content, and conversion without adding permanent headcount. Engagements are framed as advisory and operational support layered on top of, or in place of, existing marketing functions. The consultancy's work is organized around what it calls a "Wasteless Growth Methodology," structured across three operational subsystems: Acquisition (SEO, search intelligence, paid acquisition), Content Interface (translating demand into understanding and trust through content architecture), and Conversion (transforming attention into client action). Concrete service lines include B2B SEO consulting, fractional SEO and AI/GEO search leadership, technical SEO, SEO keyword research, competitor research, SEO migration support, Google penalty recovery, SEO due diligence, and content pruning. Content-related services cover content audits and content strategy, while conversion work includes conversion funnel audits, funnel redesign, and landing page optimization. Growth strategy consulting extends to growth diagnostics, value stream design, and growth system re-architecture, delivered through short-term, project-based, or ongoing fractional arrangements rather than retained full-service campaigns.
