Speed

4 to fix100

  • 8 third-party services on the page

    8 third-party services load with your homepage (Google Tag Manager, loox.io and Klaviyo and others), adding 4.6 MB and 358 ms of main-thread time.

  • Shopify adds 60 ms

    60 ms

    Shopify costs a phone 60 ms of main-thread work and 4.2 MB 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.

  • Render-blocking requests

    450 ms

    3 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

  • Improve image delivery

    434 KiB

    17 images could be 434 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • Reduce unused JavaScript

    239 KiB

    About 239 KiB of JavaScript is downloaded but never used on this page.

  • 1 long task on the main thread

    1 long task block the main thread while loading, the longest for 138 ms. During a long task the page ignores taps.

  • Use efficient cache lifetimes

    57 KiB

    9 files are served with short cache lifetimes, so returning visitors download them again (57 KiB).

  • Legacy JavaScript

    19 KiB

    Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

  • Chained critical requests

    Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

  • Forced reflow

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

3 checks passed

  • Mobile performance score: 100

    100/100

    Your mobile performance score is 100. That is in Google's “good” band (90 and up).

  • Main-thread work: 1.7 s

  • Server response: 7 ms

    7 ms

    Your server sent the HTML in 7 ms, well inside Google's 600 ms guideline.

Images and page weight

1 to fix70

  • Page weight: 5.6 MB in 226 requests

    5.6 MB

    Your homepage downloads 5.6 MB in 226 requests on a phone: media 2.9 MB (1), images 1,020 KiB (33) and other files 817 KiB (115). Under 2 MB keeps phones on slow connections fast.

  • 2 images below the first screen load straight away

    2 images further down the page (134 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

  • About 1.6 g of CO₂ per visit

    1.60 g

    By the Sustainable Web Design model, a visit to your homepage emits about 1.60 g of CO₂e: 192.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 checks passed

  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

  • Images are sized for phones

    No image is downloaded at more than three times the size it is drawn on a phone.

Accessibility

2 to fixGoogle 9596

  • 7 text elements with low contrast

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

  • Scrollable region must have keyboard access (1 element)

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

  • Headings skip levels

    Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

2 checks passed

  • Every image has alt text

    All 39 images in the HTML carry an alt attribute.

  • 51 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 54 WCAG 2.2 A/AA and best-practice rules on the phone render: 51 passed and 3 failed. 3 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

2 to fixGoogle 10088

  • Title is long (72 characters)

    Your title is 72 characters, so Google will cut it off around 60: “GLASSGUARD Cleaning, Mould Removal & Surface Restoration | GLASSGUARD UK”.

  • Meta description is long (288 characters)

    Your meta description is 288 characters; Google truncates after about 160, so the end of your pitch is cut.

  • 91 internal links, 0 external

    The homepage links to 91 pages on glassguard.uk and 0 external pages.

6 checks passed

Security, domain, email and software versions
