jemsystems.ca website review

Your mobile performance score is 76. Pages that score under 90 lose visitors before the first paint.

About 256 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

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

7 images could be 110 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

tidio.co costs a phone 55 ms of main-thread work and 515 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.

8 third-party services load with your homepage (Hotjar, tidio.co and Shopify and others), adding 700 KiB and 189 ms of main-thread time.

18 files are served with short cache lifetimes, so returning visitors download them again (45 KiB).

About 27 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

1 long task block the main thread while loading, the longest for 75 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.

3 KiB could be saved by minifying JavaScript.

Your largest element takes 6.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Access Restricted”.

The page becomes fully interactive after 8.1 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 80 ms to 78 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.5 MB in 215 requests on a phone: other files 848 KiB (125), scripts 722 KiB (51) and images 680 KiB (28). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.72 g of CO₂e: 86.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

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

The homepage links to 208 pages on jemsystems.ca and 2 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

https://jemsystems.ca/pages/about-us, https://jemsystems.ca/pages/fire-alarm-design, https://jemsystems.ca/pages/bim-modeling, https://jemsystems.ca/collections/vesda-by-xtralis, https://jemsystems.ca/collections/all and https://jemsystems.ca/collections/edwards and 4 others have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 81 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

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.

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

The homepage has only about 12 words of visible text; thin pages give Google and first-time buyers little to go on.

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.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Hotjar (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 13 cookies (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 22 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
