Building for the Spain market
Spanish SEO rewards regional pages — Madrid and Barcelona behave like separate markets in search.
Practically, that shapes how we build: checkout flows use the gateways your customers already trust (Redsys, Stripe, Bizum, PayPal), prices and dates render in Spain formats, and the SEO plan targets Spain search results rather than a generic global audience. Where you serve specific cities — Madrid, Barcelona, Valencia, Seville — we build a page for each one with content written for that market.
