Site Speed Optimization
Every Millisecond Counts.
What We Do
Every second your page takes to load costs you visitors. Studies consistently show that as page load time increases, visitors abandon at growing rates. Google confirmed this behavior and built Core Web Vitals into its ranking algorithm. Slow sites rank lower, cost more per click in paid advertising, and convert fewer visitors into customers. The problems are almost always fixable. Bloated JavaScript bundles that block rendering.
Unoptimized images served at full resolution regardless of device. Render-blocking CSS and scripts loaded before content. No CDN, so every request travels to a single server. Missing caching headers that force repeat downloads. We diagnose each issue with precision and fix them in order of impact. The result is measurably faster load times, better Core Web Vitals scores, and a site that stops punishing visitors for showing up.
How We Work
We begin with a multi-tool performance audit. Lighthouse measures your scores against Google's thresholds. WebPageTest shows a waterfall of every network request and where bottlenecks occur. Real User Monitoring data, when available, reveals how actual visitors on real devices experience your site. The audit produces a prioritized list of issues ranked by impact. We fix in order: critical rendering path first, then images, then JavaScript bundles, then caching, then server configuration. Every fix is measured before and after with consistent test conditions.
We do not guess at improvement. We document it. Image optimization includes format conversion to WebP, proper sizing with responsive srcset attributes, and lazy loading below the fold. JavaScript optimization covers tree shaking, code splitting, and deferred loading. CDN configuration routes assets to edge nodes near your visitors. After the sprint, we deliver a report showing before and after metrics for every change made.
Why Running Start Digital
Frequently Asked Questions
Most sites see 40 to 70 percent improvement in Largest Contentful Paint after optimization. Results depend on how much technical debt exists in the current build.
Yes. Google uses Core Web Vitals as a ranking signal. Faster sites rank higher, get more clicks, and convert better. Speed is not optional.
Yes. We optimize WordPress sites through caching, image compression, plugin audits, database cleanup, and CDN integration. For maximum performance, we also offer migration to Next.js.
We deliver a one-time optimization sprint. For ongoing performance monitoring and maintenance, we offer monthly retainer plans.
A focused site speed sprint typically takes 2 to 4 weeks. We audit in week one, implement fixes in weeks two and three, and deliver a final benchmark report in week four.
Core Web Vitals are Google's three key performance metrics: Largest Contentful Paint measures load speed, Interaction to Next Paint measures responsiveness, and Cumulative Layout Shift measures visual stability. Poor scores directly affect your search rankings.
We diagnose both. Server response time, geographic distance from visitors, and underpowered hosting plans are common culprits. We recommend the right hosting configuration alongside code-level fixes.
