voltdata.com.au website review

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 1.0 s).

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 700 ms.

11 files are served with short cache lifetimes, so returning visitors download them again (264 KiB).

3 third-party services load with your homepage (Google Tag Manager, Google Fonts and Google Analytics), adding 224 KiB and 170 ms of main-thread time.

3 images could be 187 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

3 long tasks block the main thread while loading, the longest for 103 ms. During a long task the page ignores taps.

About 74 KiB of JavaScript is downloaded but never used on this page.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Visually, the page fills in at 4.1 s (Speed Index). Good is under 3.4 s.

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

3 images (209 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

1 image further down the page (42 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.14 g of CO₂e: 16.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

Your meta description is 200 characters; Google truncates after about 160, so the end of your pitch is cut.

No XML sitemap at https://voltdata.com.au/sitemap.xml, so Google discovers your pages only by following links.

There is no robots.txt at voltdata.com.au/robots.txt, the first file search crawlers ask for.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 26 pages on voltdata.com.au and 18 external pages.

We fetched 6 pages linked from your homepage and read each the way a search engine does.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

The homepage shows no opening hours. If customers visit or call, show when.

There is no form on the homepage, so every lead has to click through to another page first.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 495 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics and Google Tag Manager (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 2 cookies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
