sonic-brush.jp website review

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

Shopify costs a phone 2 ms of main-thread work and 389 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.

10 files are served with short cache lifetimes, so returning visitors download them again (147 KiB).

8 images could be 130 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 72 KiB of CSS is downloaded but never applied on this page.

5 third-party services load with your homepage (JSDelivr CDN, Shopify and videowise.com and others), adding 523 KiB and 9 ms of main-thread time.

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.

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

2.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 0.35 g of CO₂e: 41.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 frame has no title, so screen-reader users cannot tell what it contains.

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

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

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

Headings skip levels (h1 → h3 and h2 → h4), which makes the page harder to scan with a screen reader.

Your title is only 20 characters: “Sonic Brush® | 公式サイト”. Between 30 and 65 characters leaves room to say what you do and for whom.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

The homepage links to 73 pages on sonic-brush.jp and 13 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://sonic-brush.jp/collections/%E5%95%86%E5%93%81 and https://sonic-brush.jp/pages/contact have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 3 pages by a URL that isn't their canonical one, for example https://sonic-brush.jp/collections/%E5%95%86%E5%93%81, whose canonical is https://sonic-brush.jp/collections/%e5%95%86%e5%93%81. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://sonic-brush.jp/products/sonic-brush, https://sonic-brush.jp/products/sonic-brush-v5, https://sonic-brush.jp/products/sonic-brush%C2%AE-kids, https://sonic-brush.jp/products/nylon-mouthpiece, https://sonic-brush.jp/products/sonic-brush-head and https://sonic-brush.jp/products/foam-toothpaste and 7 others have no <h1> headline, so visitors and search engines get no clear main topic.

https://sonic-brush.jp/collections/%E5%95%86%E5%93%81, https://sonic-brush.jp/products/nylon-mouthpiece, https://sonic-brush.jp/products/sonic-brush-head, https://sonic-brush.jp/products/foam-toothpaste, https://sonic-brush.jp/products/disinfection-box-for-sonic-brush and https://sonic-brush.jp/products/3-in-1-brush-head-set and 6 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.

We fetched 15 pages linked from your homepage (of 33 found) and read each the way a search engine does.

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 91 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 Klaviyo (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 6 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.
