justeffects.co.uk website review

Your mobile performance score is 76. Pages that score under 90 lose visitors before the first paint.

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 650 ms.

About 169 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 440 ms faster on a phone.

2 images could be 77 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 400 ms faster on a phone.

About 28 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 290 ms faster on a phone.

8 third-party services load with your homepage (Privy, textify-cdn.com and Google CDN and others), adding 409 KiB and 175 ms of main-thread time.

4 files are served with short cache lifetimes, so returning visitors download them again (8 KiB).

2 long tasks block the main thread while loading, the longest for 99 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 11 KiB JavaScript that modern phones do not need.

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.

Your largest element takes 6.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “THE LEADING SUPPLIER OF PYROTECHNICS SEE THE FULL RANGE”.

The page becomes fully interactive after 8.0 s. Good is under 3.8 s.

7 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.

2 images further down the page (113 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.55 g of CO₂e: 66.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 dropdown has no label.

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

2 tap targets are too small or too close together to hit reliably with a finger.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 22 elements on the page fail this check, rated moderate by axe-core.

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

The skip-link target should exist and be focusable: 1 element on the page fails this check, rated moderate by axe-core.

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

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

Headings should not be empty: 5 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h1 → h5, h1 → h5 and h1 → h5), which makes the page harder to scan with a screen reader.

Your title is 67 characters, so Google will cut it off around 60: “Just Effects - supplier of pyrotechnics and smokes to professionals”.

There are 8 <h1> headlines (“THE LEADING SUPPLIER OF PYROTECHNICS”, “EG25 SMOKES” and “WP40 SMOKES”). One clear main headline is easier for people and search engines.

Structured data found (untyped) but with 1 problem, for example “ld+json block 1 is not valid JSON (Bad control character in string literal in JSON at position )”.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 49 pages on justeffects.co.uk 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://justeffects.co.uk/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://justeffects.co.uk/collections/wire-pull-smoke-grenades and https://justeffects.co.uk/collections/mil-x-simulation-smoke-grenades have no meta description, so Google writes the search snippet from whatever text it finds.

https://justeffects.co.uk/collections/eg25-single-colour-packs, https://justeffects.co.uk/collections/eg25-mixed-colour-packs and https://justeffects.co.uk/collections/eg25-micro-smoke-grenade use the same meta description. A description written for each page earns more clicks.

We fetched 15 pages linked from your homepage (of 30 found) and read each the way a search engine does.

On a 390 px-wide phone the page scrolls sideways, a sign that something is wider than the screen.

10 of 45 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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 445 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, 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 7 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 14 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
