What we optimize

Six deep technical performance optimizations we execute.

We don't just install a generic caching plugin. We hand-audit and optimize the entire delivery pipeline.

01

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.
02

Next-Gen Image Compression & Responsive srcset

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.
03

Critical CSS Extraction & Unused CSS Removal

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.
04

Cumulative Layout Shift (CLS) Stabilization

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.
05

Time to First Byte (TTFB) & Server Caching

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.
06

Cloudflare Edge CDN & DNS Tuning

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

Every 1-second delay costs you 10% of conversions and search rankings.

Google officially ranks websites based on Core Web Vitals. Fast sites capture market share; slow sites get penalized.

What matters Template or generic agency An Aviance build Engineered for ROI
Mobile PageSpeed Red score (20–45) on Google PageSpeed with multiple failing metrics Green score (90–98) on mobile and desktop PageSpeed benchmarks
LCP (Paint Speed) Hero image takes 4.5+ seconds to display on 4G cellular connections Largest Contentful Paint loads in under 1.5 seconds worldwide
User Interaction (INP) Clicking menus or buttons lags because JavaScript freezes the main thread Instant interaction to next paint (INP) under 100ms with smooth 60fps
Third-Party Scripts Analytics, chat widgets, and heatmaps block initial rendering Third-party tags deferred or proxied via web workers without blocking
Fix Durability Speed plugins conflict, break checkout pages, and degrade after 30 days Clean architectural code fixes that remain fast permanently

A recent project · Swarngalore

E-commerce jewellery store speed reduced from 4.8s to 0.9s with 96+ PageSpeed.

Overhauled bloated theme assets and uncompressed catalog imagery, resulting in a 34% drop in cart abandonment.

  1. 01
    Brief

    Swarngalore suffered severe mobile bounce rates due to an image-heavy e-commerce catalog that took nearly 5 seconds to load on mobile connections.

  2. 02
    Approach

    We converted 1,500+ product images to WebP, removed 14 unused plugin stylesheets, inlined critical hero CSS, and implemented Cloudflare Edge cache.

  3. 03
    Handover

    Lighthouse mobile score surged from 28 to 96, and mobile page load dropped to 0.9 seconds with zero broken checkout functionality.

01Why does Google Core Web Vitals matter for my business?

Google 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.

02How do you guarantee a 90+ Lighthouse score?

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.

03Will speeding up our site break any features or design layouts?

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.

04What is TTFB (Time to First Byte) and why is it slow?

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.

05How long does a website speed optimization project take?

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.

06Can you optimize Shopify stores as well as WordPress sites?

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.

07Will third-party scripts like Google Analytics, Facebook Pixel, and live chat still work?

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.

08Why did my previous speed plugin make my site faster on desktop but not mobile?

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.

09How do you fix Cumulative Layout Shift (CLS)?

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`.

10Will the speed improvements remain permanent after you finish?

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.
