stevensontuning.com website review

About 203 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.2 s faster on a phone.

Your mobile performance score is 58. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, Shopify and Google/Doubleclick Ads and others), adding 1.0 MB and 479 ms of main-thread time.

Google Tag Manager costs a phone 310 ms of main-thread work and 338 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.

Shopify costs a phone 166 ms of main-thread work and 622 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 2.1 s on main-thread work while loading, 909 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 250 ms.

4 long tasks block the main thread while loading, the longest for 193 ms. During a long task the page ignores taps.

About 23 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.

5 images could be 91 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

4 files are served with short cache lifetimes, so returning visitors download them again (5 KiB).

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.

Your largest element takes 10.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 10.3 s. Good is under 3.8 s.

The first text or image appears after 2.9 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 5.5 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 342 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 71 ms to 87 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.1 s to 1.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.3 MB in 196 requests on a phone: other files 976 KiB (93), scripts 727 KiB (64) and images 382 KiB (17). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.64 g of CO₂e: 77.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Elements must only use permitted ARIA attributes: 1 element on the page fails this check, rated serious by axe-core.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

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

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

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

Elements with visible text labels do not have matching accessible names. (3 elements).

Your title is 68 characters, so Google will cut it off around 60: “Canada's Premier VW/BMW Diesel Tuning Company – Stevenson Tuning Ltd”.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

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

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

The homepage links to 62 pages on stevensontuning.com 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.

/ and https://stevensontuning.com/en-ca all use the title “Canada's Premier VW/BMW Diesel Tuning Company – Stevenson Tuning Ltd”. Search engines can't tell which page to show for a search, so each competes with the others.

https://stevensontuning.com/collections/all, https://stevensontuning.com/collections/volkswagen, https://stevensontuning.com/collections/bmw, https://stevensontuning.com/collections/audi, https://stevensontuning.com/collections/porsche and https://stevensontuning.com/collections/frontpage have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 28 found) and read each the way a search engine does.

3 images failed to load on a phone, for example https://stevensontuning.com/.

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 404 ()”.

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

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.

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 1,323 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Meta Pixel (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 15 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
