vulcandelivery.com website review

13 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.6 s.

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

About 107 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 930 ms faster on a phone.

Your mobile performance score is 81. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, Google Analytics and LinkedIn Ads and others), adding 445 KiB and 502 ms of main-thread time.

Google Tag Manager costs a phone 450 ms of main-thread work and 347 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.

3 images could be 305 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

5 long tasks block the main thread while loading, the longest for 224 ms. During a long task the page ignores taps.

About 146 KiB of JavaScript is downloaded but never used on this page.

4 files are served with short cache lifetimes, so returning visitors download them again (103 KiB).

20 KiB could be saved by minifying CSS.

12 KiB could be saved by minifying JavaScript.

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 10.0 s. Good is under 3.8 s.

Your largest element takes 3.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Experience the power of real-time tracking & monitoring”. Most of its time is element render delay (1.8 s).

The first text or image appears after 2.6 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 3.6 s (Speed Index). Good is under 3.4 s.

14 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 3.8 MB in 71 requests on a phone: media 2.3 MB (1), images 677 KiB (16) and scripts 529 KiB (24). Under 2 MB keeps phones on slow connections fast.

4 images (631 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.

4 images further down the page (631 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

1 image is downloaded at several times the size a phone draws it, for example Drone_without_bg.png at 1,443 px wide, shown at 273 px. Resized copies would save about 166 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.09 g of CO₂e: 130.4 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.

Form elements should have a visible label: 1 element on the page fails this check, rated serious by axe-core.

6 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 5 elements on the page fail this check, rated moderate by axe-core.

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

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

Headings skip levels (h2 → h5 and h3 → h6), which makes the page harder to scan with a screen reader.

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is only 6 characters: “Valcun”. Between 30 and 65 characters leaves room to say what you do and for whom.

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.

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

The homepage links to 9 pages on vulcandelivery.com and 1 external page.

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://vulcandelivery.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.

Your homepage links to https://vulcandelivery.com/contact-us.html, which answers with an error. Visitors hit a dead end and search engines drop it.

https://vulcandelivery.com/contact-us/index.html and https://vulcandelivery.com/contact-us all use the title “Contact us”. Search engines can't tell which page to show for a search, so each competes with the others.

https://vulcandelivery.com/about.html, https://vulcandelivery.com/contact-us/index.html and https://vulcandelivery.com/contact-us have no meta description, so Google writes the search snippet from whatever text it finds.

https://vulcandelivery.com/contact-us/index.html and https://vulcandelivery.com/contact-us have no <h1> headline, so visitors and search engines get no clear main topic.

https://vulcandelivery.com/contact-us/index.html and https://vulcandelivery.com/contact-us have 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.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

1 image is served at too low a resolution for sharp phone screens.

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

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage has only about 160 words of visible text; thin pages give Google and first-time buyers little to go on.

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 Ads, Google Analytics, Google Tag Manager and LinkedIn Insight (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 9 cookies, 2 of them by other companies (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 14 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
