sakertool.co.uk website review

A phone's processor spends 5.4 s on main-thread work while loading, 2.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 655 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 900 ms faster on a phone.

8 third-party services load with your homepage (Google Tag Manager, Clarity and Shopify and others), adding 1.6 MB and 1.1 s of main-thread time.

Your mobile performance score is 61. Pages that score under 90 lose visitors before the first paint.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 750 ms.

10 images could be 232 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 450 ms faster on a phone.

Google Tag Manager costs a phone 355 ms of main-thread work and 666 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.

About 105 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

The page has 1,662 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

vitals.app costs a phone 103 ms of main-thread work and 368 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.

7 long tasks block the main thread while loading, the longest for 167 ms. During a long task the page ignores taps.

Polyfills for old browsers add 57 KiB JavaScript that modern phones do not need.

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

16 files are served with short cache lifetimes, so returning visitors download them again (31 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.

Your largest element takes 9.8 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 19.2 s. Good is under 3.8 s.

Visually, the page fills in at 8.6 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 291 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 138 ms to 137 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 1.7 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.0 MB in 386 requests on a phone: images 1.7 MB (37), scripts 1.7 MB (78) and other files 1.4 MB (258). Under 2 MB keeps phones on slow connections fast.

1_0ade02c2-5b29-42c4-9ac0-112afe99a4d9.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).

By the Sustainable Web Design model, a visit to your homepage emits about 1.42 g of CO₂e: 170.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 elements use ARIA attributes their role does not allow, which confuses screen readers.

Certain ARIA roles must contain particular children: 2 elements on the page fail this check, rated critical by axe-core.

ARIA attributes must conform to valid values: 2 elements on the page fail this check, rated critical by axe-core.

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

ARIA input fields must have an accessible name: 3 elements on the page fail this check, rated serious by axe-core.

Interactive controls must not be nested: 2 elements on the page fail this check, rated serious by axe-core.

Links must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

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

7 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.

Elements marked as presentational should be consistently ignored: 2 elements on the page fail this check, rated minor by axe-core.

Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h1 → h3, h1 → h3 and 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.

There are 2 <h1> headlines (“” and “”). One clear main headline is easier for people and search engines.

Your meta description is 243 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 185 pages on sakertool.co.uk and 4 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.

We fetched 15 pages linked from your homepage (of 69 found) and read each the way a search engine does.

18 of 66 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

Chrome logged issues while loading the page (“Cookie”).

Social proof on the homepage: “Over 140,000 users”. 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 carries about 266 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 2 mores (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 32 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
