Une prestation SEO viable démarre à 500€/mois minimum, avec une moyenne marché autour de 2000-2900€/mois. Les TJM s'échelonnent de 300€ (freelance junior) à 900€+ (agence premium). Quatre facteurs font exploser les coûts : taille du site, vitesse souhaitée, concurrence sectorielle et dette technique. Contrairement au discours habituel, le SEO peut produire des résultats en 6 mois avec un budget massif plutôt qu'en 12 mois avec un budget minimal.
SEO rates vary massively depending on the service provider and the project. The minimum viable investment sits around €500 per month to have support that actually generates results. Below that, it's impossible to invest enough time to make a real impact on a site. Mid-market agencies typically charge around €2,000-3,000 monthly, while premium agencies exceed €3,000. Very large accounts can go up to €25,000-30,000 per month in France.
The TJM (daily rate) reflects expertise: €300 for a junior freelancer, €400-600 for a senior, €700 for a quality mid-market agency, and up to €900 for large premium firms. These figures provide a framework, but the final price depends on multiple factors.
Four main factors influence the budget: site size (a 50,000-page e-commerce site will cost more than a showcase website), industry competition (CBD requires more effort than unexploited niches), objectives and deadlines (ranking in 6 months costs much more than over 2 years), and technical debt (an old Magento from 2008 requires a tremendous amount of corrections). A comprehensive SEO audit is priced between €1,500 and €5,000 depending on complexity.
