uswitch.com website review

Your mobile performance score is 84 (desktop: 93). Pages that score under 90 lose visitors before the first paint.

About 133 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

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.

5 long tasks block the main thread while loading, the longest for 186 ms. During a long task the page ignores taps.

About 13 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 11 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

4 files are served with short cache lifetimes, so returning visitors download them again (64 KiB).

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.

4 third-party services load with your homepage (rvu.co.uk, Builder and Trust Pilot and others), adding 8 KiB and 4 ms of main-thread time.

The page becomes fully interactive after 8.6 s. Good is under 3.8 s.

Your largest element takes 3.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “We use cookies and similar technologies. You can use the se…”.

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-10, real Chrome visitors' tap response (inp) went from 113 ms to 113 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

By the Sustainable Web Design model, a visit to your homepage emits about 0.54 g of CO₂e: 64.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 274 pages on uswitch.com and 4 external pages.

There is no /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 196 found) and read each the way a search engine does.

The page uses 1 deprecated browser API that will stop working in future browsers (“Attribution Reporting is deprecated and will be removed. See https://goo.gle/ps-status for details.”).

1 error was logged to the browser console while the page loaded, for example “Cannot read properties of undefined (reading 'register')”.

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

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

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.

Social proof on the homepage: 2 trust badges. 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.

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.

The homepage carries about 965 words of visible text.

Opening the homepage sets 11 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 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
