davison.com website review

About 885 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 5.7 s faster on a phone.

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.5 s.

16 images could be 1.3 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.3 s faster on a phone.

Your mobile performance score is 45. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google Tag Manager, Vimeo and Clarity and others), adding 1.6 MB and 861 ms of main-thread time.

Google Tag Manager costs a phone 547 ms of main-thread work and 510 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.

14 files are served with short cache lifetimes, so returning visitors download them again (130 KiB).

About 75 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

A phone's processor spends 3.5 s on main-thread work while loading, 1.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Vimeo costs a phone 216 ms of main-thread work and 1.0 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.

18 long tasks block the main thread while loading, the longest for 238 ms. During a long task the page ignores taps.

Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

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

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

The first text or image appears after 8.3 s on a phone. Good is under 1.8 s.

Your largest element takes 21.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “index_slider_products3”.

The page becomes fully interactive after 22.5 s. Good is under 3.8 s.

Visually, the page fills in at 8.9 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 116 ms to 148 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 1.9 s (75th percentile). Good is under 1.8 s.

Real visitors wait 896 ms for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 471 ms in total while the page loads. Good is under 200 ms.

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

Your homepage downloads 4.6 MB in 97 requests on a phone: images 2.5 MB (34), scripts 1.6 MB (27) and fonts 263 KiB (4). Under 2 MB keeps phones on slow connections fast.

3 images (233 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 (158 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 1.31 g of CO₂e: 157.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

2 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 10 elements on the page fail this check, rated moderate by axe-core.

Users should be able to zoom and scale the text up to 500%: 1 element on the page fails this check, rated minor by axe-core.

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

Your meta description is 168 characters; Google truncates after about 160, so the end of your pitch is cut.

1 link has no real href, so search engines can't follow it.

The homepage links to 79 pages on davison.com and 6 external pages.

We fetched 15 pages linked from your homepage (of 39 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=151010721&tm=gtm002&Ver=2&mid=fee93f4b-900b-46da-a6a7-b6ea3c3e62bb&bo=1&sid=16ade0d0d35111f18cd7c780ba20cbaf&vid=16ae3490d35111f1bafef1d2194d1b4c&vids=1&msclkid=N&pi=9.

10 of 35 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

4 errors were logged to the browser console while the page loaded, for example “Unexpected end of input”.

3 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

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

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

davison.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

davison.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

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 1,018 words of visible text.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Microsoft Ads and Microsoft Clarity (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 10 cookies, 2 of them by other companies (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 21 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
