jksmfg.com website review

About 778 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.4 s faster on a phone.

27 files are served with short cache lifetimes, so returning visitors download them again (879 KiB).

24 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.6 s.

Your mobile performance score is 38. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.3 s on main-thread work while loading, 1.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Affirm and Facebook and others), adding 1.8 MB and 1.6 s of main-thread time.

Google Tag Manager costs a phone 483 ms of main-thread work and 466 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.

Affirm costs a phone 345 ms of main-thread work and 169 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.

Facebook costs a phone 265 ms of main-thread work and 285 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.

roseperl.com costs a phone 145 ms of main-thread work and 388 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.

The page has 1,830 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

13 long tasks block the main thread while loading, the longest for 232 ms. During a long task the page ignores taps.

9 images could be 132 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 37 KiB JavaScript that modern phones do not need.

About 34 KiB of CSS is downloaded but never applied on this page.

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.

5 KiB could be saved by minifying JavaScript.

4 KiB could be saved by minifying CSS.

Your largest element takes 18.2 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 21.3 s. Good is under 3.8 s.

The first text or image appears after 5.4 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 7.7 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 851 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 124 ms to 146 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 1.3 s to 1.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.7 MB in 275 requests on a phone: scripts 2.1 MB (100), other files 757 KiB (103) and images 467 KiB (18). Under 2 MB keeps phones on slow connections fast.

JKS_Q2_2026_Campaign-1080x1350-JspecLA.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 1.04 g of CO₂e: 124.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

Links must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 9 elements on the page fail this check, rated moderate by axe-core.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

Headings skip levels (h1 → h3 and h2 → h5), which makes the page harder to scan with a screen reader.

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

4 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 200 pages on jksmfg.com and 13 external pages.

We fetched 15 pages linked from your homepage (of 85 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

The homepage has only about 230 words of visible text; thin pages give Google and first-time buyers little to go on.

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, Klaviyo 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 18 cookies, 1 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 39 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
