institutskin.co.uk website review

About 473 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.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.5 s.

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

8 third-party services load with your homepage (Google Tag Manager, Facebook and Hotjar and others), adding 1.1 MB and 649 ms of main-thread time.

1 image could be 63 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.

Google Tag Manager costs a phone 353 ms of main-thread work and 519 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 files are served with short cache lifetimes, so returning visitors download them again (252 KiB).

A phone's processor spends 2.0 s on main-thread work while loading, 1.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 49 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

Polyfills for old browsers add 31 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

6 long tasks block the main thread while loading, the longest for 163 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).

7 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.

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

Your largest element takes 8.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 13.0 s. Good is under 3.8 s.

Visually, the page fills in at 5.1 s (Speed Index). Good is under 3.4 s.

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

The layout shifts by 0.177 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Scripts block taps and scrolling for 275 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.4 s to 1.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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 2.7 MB in 218 requests on a phone: scripts 1.3 MB (59), other files 854 KiB (133) and images 296 KiB (10). Under 2 MB keeps phones on slow connections fast.

GlycolicScrub14-2-960x960.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

1 image is downloaded at several times the size a phone draws it, for example Skinstitut_Logo_New.png at 6,987 px wide, shown at 77 px. Resized copies would save about 64 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 0.77 g of CO₂e: 93.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

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

7 elements hidden from screen readers can still receive keyboard focus.

Elements must only use permitted ARIA attributes: 2 elements on the page fail this check, rated serious by axe-core.

<html> element must have a lang attribute: 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: 6 elements on the page fail this check, rated moderate by axe-core.

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

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

The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

Alternative text of images should not be repeated as text: 2 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h2 → h4), 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.

Your meta description is 280 characters; Google truncates after about 160, so the end of your pitch is cut.

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

Your <h1> is empty.

The homepage links to 155 pages on institutskin.co.uk and 5 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.

https://skinstitut.co.uk/collections/regime-calming took over 3 s to send its HTML from our server.

We fetched 15 pages linked from your homepage (of 53 found) and read each the way a search engine does.

13 of 37 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 401 ()”.

Social proof on the homepage: 5 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

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

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 397 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Hotjar and Klaviyo and 1 more (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 14 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 31 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
