magic-mountain.co.uk website review

About 572 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.6 s faster on a phone.

13 files are served with short cache lifetimes, so returning visitors download them again (270 KiB).

Your mobile performance score is 69. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Facebook, Clarity and Klaviyo and others), adding 1.3 MB and 488 ms of main-thread time.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 350 ms.

A phone's processor spends 3.4 s on main-thread work while loading, 1.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Shopify costs a phone 18 ms of main-thread work and 342 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.

5 images could be 86 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. 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.

5 long tasks block the main thread while loading, the longest for 98 ms. During a long task the page ignores taps.

11 KiB JavaScript is shipped twice across bundles.

About 11 KiB of CSS is downloaded but never applied 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.

3 KiB could be saved by minifying CSS.

Your largest element takes 11.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 12.4 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 1.9 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 115 ms to 125 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.3 s to 1.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.6 MB in 234 requests on a phone: scripts 1.4 MB (96), other files 773 KiB (110) and images 146 KiB (9). Under 2 MB keeps phones on slow connections fast.

4 images (314 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 0.73 g of CO₂e: 87.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA attributes must conform to valid values: 1 element on the page fails this check, rated critical by axe-core.

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

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

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

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

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

Your meta description is 175 characters; Google truncates after about 160, so the end of your pitch is cut.

No XML sitemap at https://www.magic-mountain.co.uk/sitemap.xml, so Google discovers your pages only by following links.

The homepage links to 144 pages on magic-mountain.co.uk and 6 external pages.

Your Organization JSON-LD is missing logo, description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

There is no https://www.magic-mountain.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.

We fetched 15 pages linked from your homepage (of 96 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “An error has been thrown while configuring your widget AbortError: signal is aborted without reason AbortError: signal …”.

Social proof on the homepage: 16 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 610 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel 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 15 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 26 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
