Semji
Content SEO and GEO platform for brands
Semji is a Lyon-based content SEO platform, founded in 2013, that helps marketing teams prioritise and optimise pages for search performance, and now for AI answers: its GEO offering audits how a brand is cited across ChatGPT, Perplexity, Gemini and Google AI Overviews and pilots optimisation. It claims more than 500 corporate customers. Note: it is a content-marketing platform for brands and e-commerce — a weak fit for single-location local SEO, listed here for merchants with significant content operations.
Our reading. Best for content-heavy retail and e-commerce brands with an in-house team — not for single-location local SEO.
Strengths
- Mature content-SEO platform extended early to GEO/AI-citation auditing
- Combines software with consulting and training, useful for teams new to AEO/GEO
- Backed by Allianz France (InnovAllianz); solid French enterprise references
Limits
- No local-SEO features (listings, maps, reviews) — aimed at content teams, not shop counters
- Opaque enterprise pricing; overkill below a dedicated content team
Founded 2013 in Lyon; 500+ corporate customers and Allianz France at the capital
500+ companies across 175 countries; Intelligence Hub GEO covers ChatGPT, Perplexity, Gemini and AI Overviews; operates a hybrid platform-plus-agency model
