BS Property Group — Miami real-estate digital rebuild

BS Property Group — a boutique North Miami agency specialising in waterfront and the premium segment from Brickell to Bal Harbour. $1.2B in closed deals, sixteen years on the market, cross-border buyers from São Paulo to Shanghai. The old site ran on AngularJS — a framework EOL’d in 2022. Each page loaded ~96 JavaScript files, listing pages rendered in the browser (Google did not index them), property cards opened in modals without dedicated URLs. Sharing a property on WhatsApp showed no preview. The most critical failure: "favourite" and "saved search" were gated behind mandatory registration — the site shed about 70% of first-session visitors on the spot.

Anonymous favourites: +15–20%. Three CTAs per card instead of one: +30–50%. Premium agent form with photo, rating, online indicator, twelve-minute reply promise: +35–60%. Sub-2s LCP: +25–35%. Social proof (views per week, inquiries): +10–20%. Combined effect (not additive): 2–4× to leads. Plus the long-term lever — SSR and indexable URLs open organic traffic from Google, expected 3–5× growth over six months.
