Lyon-based SEO, GEO and paid search agency with seven French offices
About NOIISE
NOIISE is an independent French digital marketing agency headquartered in Lyon. Their history goes back to 1999, and they were formed from the merger of two SEO firms, 1ere Position and Open Linking. Offices now cover Lyon, Paris, Marseille, Montpellier, Nantes, Lille and Aix-les-Bains. Mathieu Jarsaillon is managing director, and Maud Sanselone joined in early 2026 as group sales director. Bpifrance has taken a minority stake to fund growth, and NOIISE in turn has invested in White Mirror, a social media and content agency. The agency has around 125 staff and had 2025 revenue of about 9.2 million euros.
Their SEO method starts with market, persona and search-intent research, then moves to crawl audits covering internal linking, structured data, Core Web Vitals and server logs. Content work aims for high information gain using client expertise and original data, backed by E-E-A-T and reputation work, digital PR and link building, with continuous measurement. They have added generative engine optimisation, including audits of how a brand shows up in AI answers, ongoing GEO support and in-house software for tracking AI mentions. SEO sits next to paid search on Google, Microsoft and ChatGPT ads, social media, web design and analytics.
Their dental experience is with a supplier rather than a practice. Labocast, a dental prosthesis laboratory of more than 35 years serving dentists and orthodontists, had three near-identical websites competing with each other. Over a four-year engagement led by senior SEO consultant Brice Castaing, NOIISE merged them onto one domain with new architecture, design and content, with first-page keywords up 6,250 percent, organic sessions up 530 percent and leads up 750 percent. Other health-sector work includes Bayer France and Mitosyl. For local search, they took La Maison Optical to first place for optician searches in Saint-Raphael, the kind of local result a dental clinic would look for.
On La Fabrique du Net they score 4.48 from nine verified reviews. Reviewers most often mention responsiveness, professionalism and availability, followed by long-term support, sector knowledge and a patient, teaching style. Several describe keeping the same contacts for years, and two optician clients describe ranking gains.
Monthly SEO support starts at 900 euros, though one day of work a month may be too little for ambitious goals. The minimum project is 1,000 euros, and the median is around 20,000 euros. Clients receive monthly reports and real-time dashboards. Awards include a 2026 SEMY Award for best GEO campaign, a 2024 SEMY Award for best SEA campaign and 2022 SEOCamp awards for SEO and content marketing. They hold Google Partner Premier and Microsoft Advertising partner status and EcoVadis certification. Their scale and French-language focus suit dental groups, labs and multi-site networks in France more than a single small practice abroad.
