mescius.com website review

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

20 files are served with short cache lifetimes, so returning visitors download them again (3.6 MB).

Your mobile performance score is 81. Pages that score under 90 lose visitors before the first paint.

Google Tag Manager costs a phone 323 ms of main-thread work and 178 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.

1 image could be 309 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 292 KiB of JavaScript is downloaded but never used on this page.

A phone's processor spends 2.7 s on main-thread work while loading, 703 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Google Fonts costs a phone 17 ms of main-thread work and 736 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.

4 third-party services load with your homepage (Google Tag Manager, Google Fonts and JSDelivr CDN and others), adding 930 KiB and 340 ms of main-thread time.

About 195 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.

9 long tasks block the main thread while loading, the longest for 238 ms. During a long task the page ignores taps.

32 KiB could be saved by minifying CSS.

The HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.

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.

2 KiB could be saved by minifying JavaScript.

The page becomes fully interactive after 11.0 s. Good is under 3.8 s.

Visually, the page fills in at 6.5 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 511 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 0.9 s to 1.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.5 MB in 55 requests on a phone: media 2.3 MB (2), images 792 KiB (7) and scripts 608 KiB (8). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.28 g of CO₂e: 153.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Your title is only 12 characters: “MESCIUS inc.”. Between 30 and 65 characters leaves room to say what you do and for whom.

Your meta description is only 69 characters: “メシウス株式会社（MESCIUS inc.）の企業サイトです。「世界の、役に立つ。」当社の理念、企業情報、採用情報などをご紹介いたします。”. 70 to 160 characters is enough to sell the click.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

No XML sitemap at https://www.mescius.com/sitemap.xml, so Google discovers your pages only by following links.

The homepage links to 53 pages on mescius.com and 0 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.

There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

/ and /en/default.html all use the title “MESCIUS inc.”. Search engines can't tell which page to show for a search, so each competes with the others.

/about/default.html, /about/overview.html, /about/philosophy.html, /about/greeting.html, /about/history.html and /about/sustainability.html and 8 others have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

/contact/default.html took over 3 s to send its HTML from our server.

We fetched 15 pages linked from your homepage (of 25 found) and read each the way a search engine does.

11 of 27 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage has only about 30 words of visible text; thin pages give Google and first-time buyers little to go on.

There is no form on the homepage, so every lead has to click through to another page first.

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 Analytics and Google Tag Manager (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 2 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 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
