sekisuidiagnostics.com website review

11 images could be 3.8 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 6.6 s faster on a phone.

9 files are served with short cache lifetimes, so returning visitors download them again (3.3 MB).

Your mobile performance score is 70. Pages that score under 90 lose visitors before the first paint.

About 161 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 780 ms faster on a phone.

4 third-party services load with your homepage (Google Tag Manager, cdn-cookieyes.com and AddToAny and others), adding 4.0 MB and 170 ms of main-thread time.

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 400 ms.

sekisui-dx.com costs a phone 0 ms of main-thread work and 3.7 MB 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.

1 long task block the main thread while loading, the longest for 113 ms. During a long task the page ignores taps.

About 10 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.

Your largest element takes 12.6 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 12.7 s. Good is under 3.8 s.

Visually, the page fills in at 3.7 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.3 s to 1.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.7 MB in 43 requests on a phone: images 4.0 MB (14), scripts 344 KiB (13) and fonts 304 KiB (4). Under 2 MB keeps phones on slow connections fast.

2 images weigh 2.7 MB together. On a phone connection a single image that size takes seconds.

3 images are downloaded at several times the size a phone draws them, for example Sustainable-Lab-Practices.png at 1,535 px wide, shown at 350 px. Resized copies would save about 949 KiB.

11 images (4.0 MB) are 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.

10 images further down the page (2.9 MB) 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 1.33 g of CO₂e: 160.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

All page content should be contained by landmarks: 18 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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

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

Structured data found (Article, ImageObject, Organization and Person) but with 1 problem, for example “Article: missing datePublished”.

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

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

The homepage links to 123 pages on sekisuidiagnostics.com and 13 external pages.

https://sekisuidiagnostics.com/products, https://sekisuidiagnostics.com/products/clinical-chemistry/clinical-chemistry-reagents, https://sekisuidiagnostics.com/products/clinical-chemistry/sekure-clinical-chemistry-reagents, https://sekisuidiagnostics.com/products/clinical-chemistry/calibrators-controls-linearity, https://sekisuidiagnostics.com/products/clinical-chemistry/bulk-reagents and https://sekisuidiagnostics.com/product/stat-site and 5 others use the same meta description. A description written for each page earns more clicks.

We fetched 15 pages linked from your homepage (of 52 found) and read each the way a search engine does.

4 of 13 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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.

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 483 words of visible text.

Before a visitor clicks anything, the page loads Google Tag Manager (measured from a US location before any click). A consent tool (CookieYes) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 2 cookies (measured from a US location before any click).

Loading the homepage contacts 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
