Website engineering standards

We build websites like engineers.

Every site we deliver is tested with Google Lighthouse. Speed, structure and stability are measured, not assumed, and published on both mobile and desktop.

What we measure

The metrics that actually matter.

Google uses these exact signals in its ranking algorithm. Faster sites rank higher, convert better and keep visitors longer.

LCP

Largest Contentful Paint

When the largest visible element, usually a hero image or headline, fully loads. This is what a visitor sees first and judges your brand by.

Good: under 1.2s desktop / 2.5s mobileIndustry avg 4.0s+
TBT

Total Blocking Time

How long the browser is blocked from responding to clicks, scrolls or taps. High TBT makes a site feel frozen even after it looks loaded.

Good: under 150msOur target: 0ms
CLS

Cumulative Layout Shift

Whether elements jump around as the page loads: buttons moving before you click, text shifting. It affects trust and ad quality scores.

Good: under 0.1Perfect: 0
PERF

Performance score

A composite score from 0 to 100 from Google Lighthouse. We publish mobile and desktop separately. Mobile is the harder test, and the one Google ranks on.

Our target: 90+ on mobile
SI

Speed Index

How quickly the page content is visually filled in during load. Lower is better. It keeps the screen looking complete without delay.

Good: under 1.8sOur target: under 1.5s
CODE

Code and asset efficiency

WebP/AVIF image compression, preloaded critical styles, no unused JavaScript and aggressive Cloudflare edge caching.

Zero bloated pluginsPure static performance

Every site below was built and delivered by Usher Media. Scores come from Google Lighthouse 12.x, tested 9 September 2026, median of three runs on mobile and desktop presets. The first client is an Australian business and the rest are in India.

Transparency note

The Lotus Polyclinic site scores 95 on desktop and 68 on mobile. The gap is Total Blocking Time: about 1.6 seconds of JavaScript that leaves the page unresponsive to taps after it appears. Most of it is the conversion tracking that makes the clinic's ad spend measurable: Google Ads, GA4, Meta Pixel and session recording. We are re-sequencing those tags, not removing them. We publish the mobile number because mobile is the number Google uses.

Stylewell Interior Design (audit 2 June 2026): Best Practices sits at 77 against our 90+ target because of third-party widget caching. It is a named open item in ongoing development.

Why it matters

What these scores mean for your business.

Higher Google rankings

Core Web Vitals are ranking factors.

LCP, TBT and CLS are direct ranking signals. A site that scores 99% on performance has a structural advantage over slower competitors. All sites pass Google's Core Web Vitals threshold.

Better ad performance

Faster pages cost less per click.

Meta and Google both score your landing page quality. Faster, more stable pages get lower cost per click and higher ad relevance, which lowers your cost per lead. CLS is 0 on 2 of 3 sites.

More conversions

Speed turns visits into inquiries.

Google research confirms that 53% of mobile visits are abandoned if a page takes over 3 seconds. Our fastest LCP is 0.6s, on Spotto Finance.

Zero outsourcing risk

Built in-house, every time.

No third-party developers, no freelancers, no handover gaps. We own the code, monitor the scores and fix issues without renegotiating scope. 15 in-house specialists, zero outsourcing.

Our process

How we achieve these scores.

01

Performance-first architecture

Every site is built static-first, with no bloated CMS and no unnecessary plugins. Minimal dependencies mean minimal load time. We design for speed before we design for aesthetics.

02

Image optimization pipeline

All images are compressed and converted to next-gen formats (WebP/AVIF). Explicit dimensions on every image element prevent layout shift, and off-screen assets load lazily.

03

Font and CSS delivery

Google Fonts are preloaded with font-display:optional. CSS is minified and critical styles are inlined for above-the-fold content, with zero render-blocking stylesheets on the critical path.

04

Cloudflare edge delivery

Sites deploy on Cloudflare Pages and serve from the nearest global edge node to your visitor. Aggressive cache headers on static assets remove redundant round-trips.

05

Lighthouse verification before delivery

Every website runs through Google Lighthouse CLI (mobile and desktop presets) and Google PageSpeed Insights before handover. We do not ship until scores meet our internal thresholds.

06

Ongoing monitoring and optimization

Performance is not a one-time event. As your content grows, we re-test and re-optimize. Monthly reports include website health alongside marketing metrics.

Reproducible

Check us. Every number.

Paste any of these URLs into Google PageSpeed Insights and compare. We run Lighthouse in mobile and desktop presets before every handover.
