I built Luxury Hotel Offers, a fully static site with 3,400+ listings that generates 4,400 HTML pages at build time. No SSR, no database at runtime. Here are the four hardest scaling problems I hit.
1. Googlebot's 2 MB HTML Limit
With 3,400 hotels on one listing page, the naive approach (render all cards in HTML) produced a 9 MB page. Googlebot truncates at 2 MB and ignores the rest.
The fix: cap the initial HTML at 400 cards. The remaining 2,500+ cards are generated as a separate HTML fragment file at a predictable URL (/data/cards/{slug}-remaining/). A "Load More" button injects 48 cards at a time from the fragment. The first search or filter interaction loads the entire fragment so all cards are available for client-side filtering.
This keeps every page under 2 MB for crawlers while giving users access to everything.
