330collins.com website review

11 files block the first paint until they finish downloading. Deferring or inlining them could save about 4.2 s.

About 595 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.1 s faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 1.6 s).

About 190 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.1 s faster on a phone.

Your mobile performance score is 54. Pages that score under 90 lose visitors before the first paint.

5 third-party services load with your homepage (Google CDN, Google Tag Manager and Other Google APIs/SDKs and others), adding 1.0 MB and 364 ms of main-thread time.

Polyfills for old browsers add 40 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 350 ms faster on a phone.

Google CDN costs a phone 251 ms of main-thread work and 743 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

14 KiB could be saved by minifying CSS.

2 images could be 93 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

6 long tasks block the main thread while loading, the longest for 90 ms. During a long task the page ignores taps.

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

The page becomes fully interactive after 14.6 s. Good is under 3.8 s.

Your largest element takes 6.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “HThree City Australia Pte. Ltd.”.

Visually, the page fills in at 9.4 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 4.4 s on a phone. Good is under 1.8 s.

The layout shifts by 0.157 while loading, so content jumps under the reader's thumb. Good is under 0.1.

2 images have no width and height attributes, so the layout jumps as each one loads.

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.

Your homepage downloads 2.6 MB in 54 requests on a phone: scripts 1.2 MB (19), images 450 KiB (15) and other files 359 KiB (6). Under 2 MB keeps phones on slow connections fast.

1 image is downloaded at several times the size a phone draws it, for example ficon1.png at 1,099 px wide, shown at 223 px. Resized copies would save about 32 KiB.

4 images (295 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.74 g of CO₂e: 88.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

5 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

All page content should be contained by landmarks: 19 elements on the page fail this check, rated moderate by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

63 visible links have no text or label, so screen readers cannot say where they go.

6 form fields have no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h2 → h6), which makes the page harder to scan with a screen reader.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

2 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 27 pages on 330collins.com and 6 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://330collins.com/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

https://330collins.com/location, https://330collins.com/building, https://330collins.com/sustainability and https://330collins.com/privacy-policy have no meta description, so Google writes the search snippet from whatever text it finds.

https://330collins.com/location, https://330collins.com/building, https://330collins.com/sustainability and https://330collins.com/privacy-policy have no <h1> headline, so visitors and search engines get no clear main topic.

https://330collins.com/sustainability has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 4 pages linked from your homepage and read each the way a search engine does.

Large scripts ship without source maps.

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 has only about 162 words of visible text; thin pages give Google and first-time buyers little to go on.

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

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.

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