Speed is not a luxury — it's a ranking factor. Google has confirmed that Core Web Vitals directly impact search rankings, and studies consistently show that faster websites convert better. A one-second delay in page load time can reduce conversions by 7%. For businesses in Salem competing for local search visibility, a slow website means lost customers to faster competitors.
At Fillicore Technologies, we don't just run PageSpeed Insights and call it a day. We perform deep performance audits, identify the specific bottlenecks slowing your site, and implement targeted optimizations that deliver measurable improvements. From image compression and lazy loading to server-side rendering and CDN configuration — we make your website fast on every device, every network, everywhere in Tamil Nadu and beyond.
01 — Core Web Vitals
Google's Core Web Vitals are the three metrics that determine your performance score.
Largest Contentful Paint measures how quickly the main content loads. We optimize hero images, preload critical resources, implement server-side rendering, and configure CDN edge caching to achieve LCP under 2.5 seconds.
Interaction to Next Paint measures how quickly your site responds to user interactions. We optimize JavaScript execution, break up long tasks, use web workers for heavy computation, and defer non-critical scripts to achieve INP under 200ms.
Cumulative Layout Shift measures unexpected layout movements. We set explicit dimensions for images and ads, use font-display swap, reserve space for dynamic content, and implement skeleton screens to achieve CLS under 0.1.
02 — Techniques
We apply a comprehensive set of optimization techniques tailored to your specific bottlenecks.
Convert images to WebP/AVIF formats, implement responsive images with srcset, lazy load below-the-fold images, and use CDN-based image transformation. Typically reduces page weight by 40-60% without visible quality loss.
Split JavaScript bundles by route, tree-shake unused code, defer non-critical scripts, and implement dynamic imports. Combined with critical CSS extraction and minification, your pages load only what they need.
Configure CloudFront, Cloudflare, or Fastly CDN with optimal cache headers. Implement browser caching, service workers for offline support, and edge caching strategies that serve content from the nearest location to your Salem and Tamil Nadu users.
03 — Features
Every optimization project we deliver includes these essential capabilities.
Set and enforce performance budgets in your CI/CD pipeline. Automated alerts when bundle sizes exceed limits, ensuring your site stays fast as new features are added.
SSR and static site generation for React, Next.js, and Vue applications. Pre-render critical pages for instant loading while maintaining dynamic interactivity.
Extract and inline above-the-fold CSS, defer the rest. Eliminates render-blocking stylesheets and ensures your page paints instantly on first load.

Before/after benchmarks across devices and network conditions.
Ongoing performance monitoring and regression prevention.
05 — FAQ
Core Web Vitals are Google's metrics for measuring user experience: LCP (Largest Contentful Paint) measures loading speed and should be under 2.5 seconds, INP (Interaction to Next Paint) measures responsiveness and should be under 200ms, and CLS (Cumulative Layout Shift) measures visual stability and should be under 0.1. These directly impact your Google search rankings.
Your website should load in under 3 seconds on mobile and under 2 seconds on desktop. Studies show that 53% of mobile users abandon sites that take longer than 3 seconds to load. For e-commerce, every 100ms improvement in load time can increase conversion rates by up to 1%.
No. We follow a careful, incremental approach — optimizing one element at a time and testing thoroughly after each change. We maintain staging environments for testing, implement changes with rollback capability, and verify functionality across all browsers and devices before going live.
