The problem
A rental marketplace had to rank product pages and keep checkout fast enough that shoppers finished paying.
What we did
- Server-rendered dynamic routes so product and category pages stay crawlable.
- Wired Stripe into a tighter checkout path to cut drop-off.
- Split heavy UI with dynamic imports and caching to protect time-to-interactive.
Why performance and checkout were one problem
A marketplace page can look ready before it is ready. If the JavaScript bundle is still loading when a shopper taps "Rent" or "Pay", nothing happens, and trust drops at the exact moment you ask for a card. So the checkout work and the performance work were planned together: a faster interactive page and a shorter payment path both protect the same moment.
Server rendering where it pays off
Product and category pages were server-rendered because they do two jobs: they rank in search and they start the purchase. Real HTML on first paint means search engines index every product and shoppers see content instead of a spinner. Pages that do neither, like account settings, gain little from SSR, so the server cost belongs where it earns something.
A shorter Stripe path
Every screen between "I want this" and "paid" is a place to leave. Stripe was wired into a tighter checkout flow with fewer steps, so shoppers reached payment faster and with fewer decisions on the way. Heavy UI such as galleries and filters was split out with dynamic imports, and stable data was cached, so the pay button responded sooner on mid-range phones.
Applying this to your marketplace
Measure Interaction to Next Paint and Largest Contentful Paint on product, cart and checkout pages using real mobile traffic. Server-render the routes that rank and sell. Count the screens from cart to paid and remove one. Confirm orders from Stripe webhooks rather than browser redirects, and use idempotency keys so a double tap never charges twice.
Outcome
Cart abandonment dropped 30% and time-to-interactive improved 20% after the performance and checkout work landed.
