Strasbourg network of freelance SEO, SEA, CRO and AI consultants plus Qualiopi training
About Conversion Boosters
Conversion Boosters is based at 5 Quai de Paris in Strasbourg. It is not a conventional agency. It runs a selective network of about 100 independent consultants and trainers in e-marketing and generative AI. Members work from cities including Paris, Lyon, Lille, Bordeaux, Nantes, Toulouse, Brussels, Luxembourg, Lausanne and Montreal. It was founded in 2017. The firm began when two web marketers kept hearing marketing managers complain about their usual providers. At the same time, they saw that senior specialists were going freelance.
The core team goes by first names. Adrien is CEO and runs the website division. Alphonse heads data and AI, Aurélie leads social media and content, and Vinciane runs training. Each consultant is recruited through two interviews and reference checks and has 8 to 25 years of experience. A framework contract and Hiscox liability insurance cover every mission. Clients rate the consultant after each one.
Services fall into acquisition, conversion, data and AI. Acquisition covers SEO and GEO audits, SEO overhauls, SXO, Google Ads and social ads, and email automation. Conversion work includes CRO and UX audits, A/B testing, heatmaps, user testing and accessibility. Data work covers GA4, Matomo, tag management, server-side tracking, Looker Studio dashboards and GDPR compliance. The firm also offers outsourced CMO or digital director roles, custom AI agents and more than 80 training courses. These include courses on ChatGPT, Claude, Google Ads and analytics. Its training arm holds Qualiopi certification, so French employers can fund courses through their OPCO training budgets. It also carries the Activateur France Num label.
The firm has more than 600 clients and has trained over 2,000 learners. Its references cover around 330 clients, from Lidl, Crédit Mutuel and SNCF to online shops such as Electrostock, Allnatura and Fazup. A few health names appear, including CHU Toulouse, Softway Medical and Frenchtooth. The work done for them is not described, and no dental practice case study is published.
On Google the firm shows 5.0 from about 140 reviews. GoodFirms has no reviews yet. Hourly rates run $100 to $149, with minimum budgets of $1,000 to $10,000. Consultants charge freelance rates, and the firm promises a reply within 24 hours and a quote within 48 hours.
For dental practices, the fit is best for multi-site groups or practices that want to measure bookings properly, test their booking pages, or train in-house staff on SEO and ads. Single practices wanting a done-for-you local dental SEO package will find no dental-specific offer here.
