jdmenginezone.com website review

Your mobile performance score is 74. Pages that score under 90 lose visitors before the first paint.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 500 ms.

A phone's processor spends 3.0 s on main-thread work while loading, 899 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Shopify costs a phone 220 ms of main-thread work and 580 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 198 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 260 ms faster on a phone.

7 third-party services load with your homepage (Shopify, notify-me.io and simprosysapps.com and others), adding 883 KiB and 316 ms of main-thread time.

3 images could be 105 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 250 ms faster on a phone.

About 65 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 180 ms faster on a phone.

11 files are served with short cache lifetimes, so returning visitors download them again (198 KiB).

3 long tasks block the main thread while loading, the longest for 60 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 7 KiB JavaScript that modern phones do not need.

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 6.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 7.6 s. Good is under 3.8 s.

The first text or image appears after 2.1 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 3.6 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 79 ms to 95 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.6 s to 1.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 10.7 MB in 447 requests on a phone: media 8.0 MB (2), scripts 1.0 MB (222) and other files 974 KiB (171). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 3.02 g of CO₂e: 362.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA attributes must conform to valid values: 2 elements on the page fail this check, rated critical by axe-core.

1 element hidden from screen readers can still receive keyboard focus.

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

All page content should be contained by landmarks: 17 elements on the page fail this check, rated moderate by axe-core.

Alternative text of images should not be repeated as text: 13 elements on the page fail this check, rated minor by axe-core.

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

There are 2 <h1> headlines (“JDM Engine Zone” and “ABOUT US”). One clear main headline is easier for people and search engines.

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

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

The homepage links to 89 pages on jdmenginezone.com and 3 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://jdmenginezone.com/collections and https://jdmenginezone.com/pages/why-shop-with-us have no <h1> headline, so visitors and search engines get no clear main topic.

https://jdmenginezone.com/collections/mitsubishi-engines, https://jdmenginezone.com/collections/scion-engines, https://jdmenginezone.com/collections/volkswagen-engines, https://jdmenginezone.com/collections and https://jdmenginezone.com/pages/why-shop-with-us took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 24 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.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

The homepage carries about 352 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 14 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 19 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
