Building for the France market
French audiences expect fully localised copy — machine-translated sites lose both trust and rankings.
Practically, that shapes how we build: checkout flows use the gateways your customers already trust (Stripe, Lydia, PayPal, Sofort), prices and dates render in France formats, and the SEO plan targets France search results rather than a generic global audience. Where you serve specific cities — Paris, Lyon, Marseille, Toulouse — we build a page for each one with content written for that market.
