JavaScript Deferral & Tree-Shaking
Delaying, minifying, and eliminating render-blocking JavaScript files and unused third-party tracking scripts.
Slashing Total Blocking Time (TBT) from 1,200ms down to zero.Slow websites destroy conversion rates and lose Google search rankings. We eliminate JavaScript bloat, optimize images, configure edge caching, and fine-tune server response times to guarantee sub-1.5s load times and 90+ Lighthouse scores.

What we optimize
We don't just install a generic caching plugin. We hand-audit and optimize the entire delivery pipeline.
Delaying, minifying, and eliminating render-blocking JavaScript files and unused third-party tracking scripts.
Slashing Total Blocking Time (TBT) from 1,200ms down to zero.Converting bloated PNG/JPEGs to modern WebP/AVIF formats, defining explicit dimensions, and adding native lazy loading.
Reducing total page weight from 8.5MB down to 850KB.Inlining above-the-fold critical CSS while deferring non-critical styling, eliminating render-blocking stylesheet delays.
Fixing Largest Contentful Paint (LCP) to load in under 1.2 seconds.Adding aspect-ratio bounding boxes to images, banners, and ads so elements don't jump around during page rendering.
Achieving a perfect 0.00 CLS score on Google Search Console.Configuring Redis object caching, Nginx FastCGI microcaching, and database query optimization on the origin server.
Dropping initial server response time from 1,400ms to under 120ms.Routing traffic through global edge data centers with HTTP/3, Brotli compression, and tiered edge caching.
Delivering instant sub-second response times worldwide.Why Aviance
Google officially ranks websites based on Core Web Vitals. Fast sites capture market share; slow sites get penalized.
If we don't achieve a 90+ Lighthouse score on your agreed key templates, you receive a full refund.
We thoroughly test all forms, shopping checkouts, sliders, and interactive menus on staging to guarantee nothing breaks.
You receive comprehensive before-and-after reports showing exact millisecond gains, payload reductions, and Core Web Vitals pass marks.
How speed optimization runs
We perform all optimizations on a private staging clone before deploying clean verified changes to production.
Running Chrome DevTools network waterfalls, profiling CPU main-thread execution, and auditing slow database queries.
Comprehensive speed diagnosis report and benchmark score.Converting all media to WebP/AVIF, stripping unused CSS, and deferring non-essential JavaScript libraries.
Total page weight reduced by over 60% on staging.Preloading critical fonts, inlining critical LCP assets, stabilizing CLS layout boxes, and reducing INP latency.
Green Core Web Vitals metrics verified in Chrome DevTools.Configuring Redis/Memcached, FastCGI microcaching, HTTP/3, and Cloudflare Tiered Edge caching.
Server TTFB reduced to under 150ms.Testing checkout flows and forms across devices, deploying to live domain, and monitoring real user metrics.
Verified 90+ Lighthouse score live on your website.Ways to start

A recent project · Swarngalore
Overhauled bloated theme assets and uncompressed catalog imagery, resulting in a 34% drop in cart abandonment.
Swarngalore suffered severe mobile bounce rates due to an image-heavy e-commerce catalog that took nearly 5 seconds to load on mobile connections.
We converted 1,500+ product images to WebP, removed 14 unused plugin stylesheets, inlined critical hero CSS, and implemented Cloudflare Edge cache.
Lighthouse mobile score surged from 28 to 96, and mobile page load dropped to 0.9 seconds with zero broken checkout functionality.

Get A Free QuoteGoogle officially incorporates Core Web Vitals (Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift) as explicit search ranking factors. Websites that fail Core Web Vitals suffer lower organic search rankings and higher cost-per-click on Google Ads. Furthermore, human visitors expect pages to load in under 2 seconds: according to industry data, every 1-second delay reduces conversions by 7% and increases bounce rates by over 30%. Passing Core Web Vitals directly protects your SEO rankings and boosts sales.
We guarantee a 90+ score because we don't rely on superficial caching plugins that conflict with code. We perform deep architectural optimizations: converting all imagery to modern WebP/AVIF formats, inlining critical CSS, deferring or eliminating render-blocking JavaScript, preloading key web fonts, stabilizing layout dimensions to eliminate CLS, and optimizing server TTFB. If we do not achieve a 90+ score on your agreed primary templates, we refund your payment in full.
No. We perform all code optimizations on an isolated staging clone of your website. We test all interactive components—including checkout payment gateways, lead forms, navigation menus, filters, and third-party widgets—to ensure 100% functionality before deploying to your live domain.
TTFB measures the time it takes between a browser requesting a page and receiving the first byte of data from the web server. High TTFB (above 600ms) is caused by unoptimized database queries, slow shared hosting, lack of object caching, or uncompressed server responses. We reduce TTFB to under 150ms by implementing Redis object caching, PHP OPcache tuning, MySQL query indexing, and Cloudflare Edge caching.
A complete speed and Core Web Vitals overhaul typically takes between 5 and 7 business days. Day 1 is dedicated to in-depth network profiling; Days 2–4 are for asset compression, JavaScript deferral, and CSS optimization; Day 5 focuses on server and CDN caching; and Days 6–7 are for cross-device QA testing and live deployment.
Yes. On Shopify, where server configuration cannot be modified, we optimize Liquid theme templates, eliminate unused app script tags, clean up old app snippets from `theme.liquid`, convert image assets to responsive WebP, preload primary hero banners, and defer third-party analytics to achieve 90+ scores.
Yes. We do not remove the tracking tools essential to your marketing. Instead, we optimize their execution order: we defer non-critical scripts until after the primary page content renders, or proxy them via lightweight asynchronous web workers. Your analytics continue to track with 100% accuracy without freezing the user's screen.
Mobile devices have significantly slower CPUs and operate on high-latency cellular 4G/5G networks compared to desktop computers with high-speed fiber internet. Many speed plugins simply minify code, which helps desktop, but leaves massive JavaScript bundles that choke mobile processors. We solve mobile speed by removing unused JavaScript entirely and optimizing the main thread execution.
Cumulative Layout Shift happens when images, fonts, or ad banners load without defined dimensions, causing the content to jump around while a user tries to read. We fix CLS by applying explicit aspect-ratio attributes to all images, reserving layout placeholders for dynamic widgets, and preloading custom web fonts with CSS `font-display: swap`.
Yes, because our changes are made at the foundational architectural level (clean code, server caching, compressed assets). To ensure staff uploads don't degrade speed in the future, we set up automated server-side image compression hooks and provide an easy guide on asset hygiene.
