Speed

3 to fix87

  • Mobile performance score: 87

    87/100

    Your mobile performance score is 87 (desktop: 94). Pages that score under 90 lose visitors before the first paint.

  • Reduce unused JavaScript

    450 ms · 71 KiB

    About 71 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.

  • 1,750 HTML elements

    The page has 1,750 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • Improve image delivery

    150 ms · 17 KiB

    1 image could be 17 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.

  • 3 third-party services on the page

    3 third-party services load with your homepage (Google Tag Manager, Google Fonts and Google/Doubleclick Ads), adding 199 KiB and 116 ms of main-thread time.

  • 3 long tasks on the main thread

    3 long tasks block the main thread while loading, the longest for 135 ms. During a long task the page ignores taps.

  • Reduce unused CSS

    58 KiB

    About 58 KiB of CSS is downloaded but never applied on this page.

  • 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.

2 checks passed

  • Main-thread work: 1.2 s

    A phone's processor spends 1.2 s on main-thread work while loading, 182 ms of it running JavaScript. That is comfortably low.

  • Server response: 20 ms

    20 ms

    Your server sent the HTML in 20 ms, well inside Google's 600 ms guideline.

Core Web Vitals

    1.8 s

    Scripts block the page for only 195 ms while loading. Good is under 200 ms.

  • First Contentful Paint: 1.2 s

    1.2 s

  • Speed Index: 1.6 s

    1.6 s

Images and page weight

100

  • About 0.2 g of CO₂ per visit

    0.25 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.25 g of CO₂e: 29.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 checks passed

  • Page weight: 891 KiB in 49 requests

    891 KiB

    Your homepage downloads 891 KiB in 49 requests on a phone: other files 343 KiB (34), scripts 163 KiB (1) and images 118 KiB (2). That is a lean page.

  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

  • Images load when needed

    Images below the first screen wait until the visitor scrolls to them.

  • Images are sized for phones

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

Accessibility

1 to fixGoogle 9599

  • 1 link without text

    1 visible link has no text or label, so screen readers cannot say where it goes.

  • Headings skip levels

    Headings skip levels (h1 → h6, h3 → h6 and h2 → h6), which makes the page harder to scan with a screen reader.

2 checks passed

  • Every image has alt text

    All 34 images in the HTML carry an alt attribute.

  • 47 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 49 WCAG 2.2 A/AA and best-practice rules on the phone render: 47 passed and 2 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

Google 100100

8 checks passed

AI search readiness

100
4 checks passed

  • AI answer engines may read the site

    Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.

  • Organization data: 6 of 6 facts

    Your Organization JSON-LD gives name, url, logo, sameAs (social profiles), description and contact details.

  • Text is in the HTML

    Your server sends the page's text in the HTML (1,579 words), so crawlers that don't run JavaScript still read it.

  • llms.txt published

    The site publishes https://yellowcom.co.uk/llms.txt (59 KiB, 165 links, though it should open with a “# Title” line), a plain-text guide to the site for AI tools.

Best practices

1 to fixGoogle 10093

  • 2 small tap targets

    2 of 9 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 checks passed

  • No console errors

    No JavaScript errors were logged while the page loaded on a phone.

  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

1 to fix95

  • Only about 210 words

    The homepage has only about 210 words of visible text; thin pages give Google and first-time buyers little to go on.

  • No map or directions link

    There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

10 checks passed

  • Clear next step on the first screen

    On a phone, the first screen shows a clear next step: “Get a Free Consultation”.

  • 20 calls to action

    The homepage has 20 calls to action, for example “Contact Us”, “Get a Free Quote” and “Get a Free Consultation”.

  • 2 short forms

    2 short forms (5 fields at most) are right on the homepage, asking for an email.

  • Social proof on the page

    Social proof on the homepage: 39 testimonial or review blocks, 2 customer or partner logos and 1 trust badge.

  • Analytics in place

    Analytics detected: Google Tag Manager.

  • Direct contact links

    Visitors can reach you directly: 18 phone links and 0 email links.

  • Opening hours shown

    Your opening hours are on the homepage.

  • Phone number on the homepage

    Your phone number is on the homepage as a tap-to-call link.

  • LocalBusiness structured data

    Your homepage describes the business with LocalBusiness JSON-LD, so search engines and AI assistants can read its address, hours and phone reliably.

  • Risk reducer mentioned

    A guarantee or risk reducer (money-back, free trial, no credit card or similar) is mentioned on the page.

Privacy and tracking

1 to fix

  • 1 tracker load before any consent

    1

    Before a visitor clicks anything, the page loads Google Tag Manager (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.

  • 3 cookies set on arrival

    3

    Opening the homepage sets 3 cookies (measured from a US location before any click).

  • No consent tool detected

    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.

  • 4 other companies contacted

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

Security, domain, email and software versions

The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at yellowcom.co.uk, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
