Lyon SEO and e-commerce agency with certified consultants and Qualiopi-certified SEO training
About 410 Gone
410 Gone is a search marketing and e-commerce agency at 6 place Dumas de Loire in Lyon's 9th arrondissement. It was founded in 2017, and Patrick Valibus has run it since November of that year. The agency employs more than 20 people across SEO, Magento, PrestaShop, paid acquisition and web marketing. It is a certified Magento and PrestaShop agency, and it also builds on Shopify.
Valibus is CEO, has more than 15 years in SEO and e-commerce, and holds the CESEO and QASEO consultant certifications. He also chairs FEPSEM, the French body for search marketing professionals, and organises the SEO CAMP'us Lyon conference. Christophe Vidal is partner and sales director. The SEO team includes senior consultant and trainer David Bardy, consultant Charly Rouget and junior consultant Marie-Alexine Augereau, with nearly 50 years of SEO experience between them.
Each SEO project starts with a free pre-audit. The full technical audit checks Core Web Vitals, internal links, robots.txt, sitemaps, crawl errors, site structure, security and how link value flows through the site. Content work is built around semantic cocoons, groups of 20 to more than 200 linked pages that answer related searches, plus audits of existing content. Netlinking and coaching complete the service. A long article on local SEO for small firms covers Google Business Profile categories, consistent contact details, photos and posts, directory listings including Doctolib for health professionals, reviews, city pages, LocalBusiness schema such as the Dentist type, and local visibility in AI assistants. The article points to Moz Local and BrightLocal as audit tools, and Bardy wrote a February 2026 guide to setting up a Google Business Profile.
Published results come from e-commerce and media. An anonymised building equipment retailer saw organic revenue rise by 231%. Photoweb in Grenoble gained 45% more organic traffic and ranked first for its main product terms within five months. A health news site recovered from a Google Discover drop and grew from about 700,000 to 12 million monthly views. Other clients include Mon Échafaudage, Groupe Couleur, Thermador Groupe, Enlaps and Conectic+. No dental practice is named. A Lyon practice would mainly use the agency's local SEO knowledge, technical audits and treatment content, or train its own staff.
Training is a separate business line, and the training activity holds Qualiopi certification. One-day courses cover beginner SEO, technical SEO, semantic SEO, GA4, site migration and Google Ads, mostly from 790 euros before tax, with log analysis at 1,190 euros. Agency fees are quoted per project, with time and deliverables set out in each quote. Valibus's personal Malt day rate is 1,600 euros.
