sensedia.com website review

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.4 s.

About 566 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.4 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, hsappstatic.net and website-files.com and others), adding 1.9 MB and 1.7 s of main-thread time.

16 files are served with short cache lifetimes, so returning visitors download them again (180 KiB).

Google Tag Manager costs a phone 607 ms of main-thread work and 527 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.

hsappstatic.net costs a phone 479 ms of main-thread work and 702 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.

A phone's processor spends 3.9 s on main-thread work while loading, 2.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

16 long tasks block the main thread while loading, the longest for 379 ms. During a long task the page ignores taps.

website-files.com costs a phone 178 ms of main-thread work and 382 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 64 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 160 ms faster on a phone.

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.

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.

Real visitors wait 6.1 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 4.7 s (75th percentile). Good is under 1.8 s.

Real visitors wait 2.8 s for your server to start answering (75th percentile). Good is under 800 ms.

Your largest element takes 12.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “This website stores cookies on your computer, used to colle…”.

The page becomes fully interactive after 17.6 s. Good is under 3.8 s.

Scripts block taps and scrolling for 1.0 s in total while the page loads. Good is under 200 ms.

The first text or image appears after 3.4 s on a phone. Good is under 1.8 s.

Real visitors wait 254 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 195 ms to 261 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 2.5 s to 4.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

Visually, the page fills in at 3.5 s (Speed Index). Good is under 3.4 s.

Your homepage downloads 2.2 MB in 123 requests on a phone: scripts 1.7 MB (52), fonts 175 KiB (5) and images 167 KiB (25). Under 2 MB keeps phones on slow connections fast.

1 image is downloaded at several times the size a phone draws it, for example 0630f611-96e1-5dc1-8d2a-6db512aa9a79.png at 400 px wide, shown at 110 px. Resized copies would save about 17 KiB.

1 image (53 KiB) is 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 (81 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 0.63 g of CO₂e: 75.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Images must have alternative text: 1 element on the page fails this check, rated critical by axe-core.

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

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

2 visible links have no text or label, so screen readers cannot say where they go.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

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

The homepage links to 127 pages on sensedia.com and 19 external pages.

We fetched 15 pages linked from your homepage (of 58 found) and read each the way a search engine does.

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: the server responded with a status of 400 ()”.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

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

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

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.

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 767 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Hotjar and HubSpot and 1 more (measured from a US location before any click). A consent tool (HubSpot cookie banner) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 4 cookies (measured from a US location before any click).

Loading the homepage contacts 27 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
