mifuko.jp website review

13 images could be 577 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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

Shopify costs a phone 96 ms of main-thread work and 470 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 (Clarity, Shopify and shop.app and others), adding 528 KiB and 221 ms of main-thread time.

4 long tasks block the main thread while loading, the longest for 101 ms. During a long task the page ignores taps.

About 32 KiB of JavaScript is downloaded but never used on this page.

About 28 KiB of CSS is downloaded but never applied on this page.

4 files are served with short cache lifetimes, so returning visitors download them again (15 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.

The page becomes fully interactive after 28.9 s. Good is under 3.8 s.

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

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 6.6 MB in 186 requests on a phone: fonts 4.0 MB (2), images 1.4 MB (28) and other files 780 KiB (98). Under 2 MB keeps phones on slow connections fast.

mv_sp_0122.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).

9 images further down the page (774 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

1 image is downloaded at several times the size a phone draws it, for example trust-link_sp.jpg at 1,300 px wide, shown at 342 px. Resized copies would save about 78 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.86 g of CO₂e: 223.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

8 visible links have no text or label, so screen readers cannot say where they go.

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

Elements with visible text labels do not have matching accessible names. (1 element).

Your meta description is 275 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 79 pages on mifuko.jp and 3 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

https://mifuko.jp/collections/bags, https://mifuko.jp/collections/2way, https://mifuko.jp/collections/market, https://mifuko.jp/collections/tote, https://mifuko.jp/collections/one-handle and https://mifuko.jp/collections/handbag and 4 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://mifuko.jp/pages/mifuko-trust and https://mifuko.jp/pages/sustainability have no <h1> headline, so visitors and search engines get no clear main topic.

https://mifuko.jp/pages/story, https://mifuko.jp/pages/mifuko-trust, https://mifuko.jp/pages/sustainability, https://mifuko.jp/pages/sizeguide and https://mifuko.jp/pages/material 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.

We fetched 15 pages linked from your homepage (of 32 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Refused to apply style from 'https://mifuko.jp/cdn/shop/t/2/assets/cuatum.css?v=2369' because its MIME type ('text/html…”.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

The homepage has only about 99 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 Meta Pixel and Microsoft Clarity (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 9 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 11 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
