Lyon paid-ads and SEO agency focused on tracked leads, with no dental specialism
About Convertix
Convertix is a French acquisition agency. Its registered office is at 254 rue Vendôme in Lyon's 3rd arrondissement, registered with the Lyon trade register (SIREN 931 970 354). It was founded in 2024 and has six people. It also has more than ten years of advertising experience and over 170 clients, which probably reflects the founders' earlier careers. The co-founders are Alexis Gaulard, the legal representative, and William, who has worked in online advertising since 2016. The site has landing pages for dozens of French cities, including Montpellier, but the only address published is in Lyon.
The agency began with paid search and later added SEO and GEO, meaning optimisation for AI-generated answers. Its paid work covers Google Ads, Meta and TikTok campaigns, as well as YouTube, Microsoft and LinkedIn ads. Every set-up includes tracking. The team installs Google Tag Manager and GA4, configures Consent Mode v2 for GDPR and can feed CRM data back so the ad platforms optimise toward profitable leads. It also writes sales pages and makes ad visuals and videos.
The SEO plan runs over six months. Months one and two cover a technical crawl, Core Web Vitals, indexing errors, semantic analysis, competitor benchmarks and server-side conversion tracking. Months three and four focus on pillar pages, supporting articles, internal linking and trust signals, with early GEO work. Months five and six add new keyword clusters and refine pages using Search Console data. Links come from editorial partnerships, digital PR and guest posts. Monthly reports cover rankings, organic traffic, leads attributed to SEO and click-through rates, and compare SEO cost against paid acquisition. The agency expects first results in two to three months and stronger gains in four to eight.
SEO starts at €1,200 excluding VAT per month for a site of 50 to 200 pages. That covers an audit, content strategy, two to four articles a month and reporting. Larger catalogues are quoted separately. Free audits are offered, and the contact form asks about ad budget in bands from under €500 to over €1,000 a month. Paid clients get a Looker Studio dashboard, a monthly report and WhatsApp contact. No contract length is published.
Named clients come from property, insurance, retail and services and include Foncia, Keolis, O2, Neovia, Génération Piscine, Kubii, Krème and César & Brutus. The César & Brutus case shows the team dropping Meta Ads for Google Ads to improve lead quality for a property manager. Impli ranks it third among Lyon Google Ads agencies. Its site has no healthcare or dental pages, so a practice would be buying general lead-generation skills rather than dental experience.
