The Brief

Load Runner Trailers moves serious volume across six Florida locations, and it does it with one of the strongest trailer catalogs in the state. None of that reached the buyer fast enough. The site was WordPress with an inventory plugin bolted on, and it failed Core Web Vitals on every measure that matters. Main content took nearly six seconds to appear on mobile. The page jumped as it loaded. Spanish-speaking buyers, a real share of the Florida market, got a Google Translate widget with zero SEO value behind it. The catalog was the competitive advantage. The website was the tax on it.

The Goal

Improve sales by making the inventory the fastest part of the buying process instead of the slowest.

The Work

A platform, not a theme. We rebuilt the site from scratch in SvelteKit and TypeScript, deployed on Cloudflare. Three environments, dev, staging, and production, with automated tests running on every change. Engineering discipline you would expect from a software company, applied to a dealership.

Six seconds to under two. Largest Contentful Paint dropped from 5.9 seconds to 1.8 seconds on mobile. Cumulative Layout Shift went to zero. The old site failed Core Web Vitals. The new one clears every threshold. Google treats those numbers as a ranking input, and buyers treat them as a reason to stay.

Inventory sync rebuilt for speed. Stock still syncs automatically from their inventory management system, but the sync now runs every 15 minutes through a dedicated Cloudflare Worker and lands in an edge-replicated database. The plugin that used to slow down every page load is gone.

A Spanish site that actually ranks. Real Spanish pages at /es/ URLs, declared in the sitemap with alternate-language tags so Google indexes them as native content. Every trailer's name, description, and color is translated at ingestion by a language model running on Cloudflare's AI platform, then stored and indexed rather than regenerated on each view. The result reads like someone who knows trailers wrote it, because the translation is trailer-aware and permanent.

Closed-loop attribution. Ad click to site visit to signed deal, tracked first-party. Closed-deal data flows back into Google and Meta so their targeting algorithms learn what an actual Load Runner buyer looks like, not what a form fill looks like.

The Result

Buyers stayed. Average engagement time more than doubled, engagement rate climbed 11.7%, and sessions rose 31% in the first full month. Sales orders were up 26% and revenue up 22% over the prior month. Load Runner is now able to invest in advertising with confidence.

Same inventory, same market, same six locations. The only thing that changed was that the site stopped getting in the way.
