warburtons.co.uk website review

29 files are served with short cache lifetimes, so returning visitors download them again (2.6 MB).

About 1.1 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 6.9 s faster on a phone.

6 images could be 644 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 3.3 s faster on a phone.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.8 s.

About 568 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 2.6 s faster on a phone.

Your mobile performance score is 57 (desktop: 76). Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and Google Maps and others), adding 1.4 MB and 564 ms of main-thread time.

Google CDN costs a phone 283 ms of main-thread work and 734 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 300 ms).

Google Tag Manager costs a phone 156 ms of main-thread work and 325 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 long tasks block the main thread while loading, the longest for 107 ms. During a long task the page ignores taps.

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

Your largest element takes 21.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “We use cookies to enhance your browsing experience, serve p…”.

The page becomes fully interactive after 21.7 s. Good is under 3.8 s.

Visually, the page fills in at 9.8 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.8 s on a phone. Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 82 ms to 88 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 3.0 s to 3.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.2 MB in 66 requests on a phone: scripts 2.1 MB (15), images 1.0 MB (22) and stylesheets 641 KiB (4). Under 2 MB keeps phones on slow connections fast.

Ad-Image-1.jpg weighs 495 KiB. On a phone connection a single image that size takes seconds.

2 images are downloaded at several times the size a phone draws them, for example Ad-Image-1.jpg at 2,359 px wide, shown at 390 px. Resized copies would save about 509 KiB.

5 images (876 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.

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

By the Sustainable Web Design model, a visit to your homepage emits about 1.20 g of CO₂e: 144.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 dropdown has no label.

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

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 13 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

20 form fields have no label, so screen readers announce an empty box and autofill guesses.

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

Alternative text of images should not be repeated as text: 1 element on the page fails this check, rated minor by axe-core.

Structured data found (Organization, SiteNavigationElement and WebSite) but with 2 problems, for example “Organization: sameAs is an empty list”.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

The homepage links to 56 pages on warburtons.co.uk and 10 external pages.

Your Organization JSON-LD is missing logo, sameAs (social profiles), 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.warburtons.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.

Your homepage links to 4 pages by a URL that isn't their canonical one, for example https://www.warburtons.co.uk/goodstuff/sustainability, whose canonical is https://www.warburtons.co.uk/goodstuff/responsible-business. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://www.warburtons.co.uk/goodstuff/sustainability, https://www.warburtons.co.uk/goodstuff/the-warburtons-foundation, https://www.warburtons.co.uk/goodstuff/product-donations, https://www.warburtons.co.uk/goodstuff/financial-giving, https://www.warburtons.co.uk/products and https://www.warburtons.co.uk/recipes took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 35 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “wp is not defined”.

Large scripts ship without source maps.

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: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

Your longest form asks for 29 fields (4 required). Every extra field lowers completion.

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 290 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager and Hotjar (measured from a US location before any click). A consent tool (CookieYes) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 1 cookie (measured from a US location before any click).

Loading the homepage contacts 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
