sangininstruments.com website review

12 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.2 s.

About 555 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

Your mobile performance score is 75. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, Shopify and POWr and others), adding 1.3 MB and 588 ms of main-thread time.

The page has 2,902 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Google Tag Manager costs a phone 213 ms of main-thread work and 532 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.

Shopify costs a phone 92 ms of main-thread work and 382 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.

2 images could be 169 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 250 ms faster on a phone.

About 25 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.

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

4 long tasks block the main thread while loading, the longest for 114 ms. During a long task the page ignores taps.

9 files are served with short cache lifetimes, so returning visitors download them again (35 KiB).

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

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 24.2 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 33.6 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 88 ms to 108 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

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 9.8 MB in 260 requests on a phone: images 7.4 MB (61), scripts 1.4 MB (77) and other files 748 KiB (86). Under 2 MB keeps phones on slow connections fast.

23 images are downloaded at several times the size a phone draws them, for example Bracelet-Sangin-Instrumnets-Professional-Kii-WEB.jpg at 2,160 px wide, shown at 62 px. Resized copies would save about 4.9 MB.

2 images weigh 1.0 MB together. On a phone connection a single image that size takes seconds.

By the Sustainable Web Design model, a visit to your homepage emits about 2.79 g of CO₂e: 335.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

22 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

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

Alternative text of images should not be repeated as text: 1 element on the page fails this check, rated minor by axe-core.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

Your <h1> is empty.

The homepage links to 181 pages on sangininstruments.com and 25 external pages.

/collections/all and /policies/shipping-policy have no meta description, so Google writes the search snippet from whatever text it finds.

/collections/all, /policies/shipping-policy, /collections, /pages/rolling-updates, /collections/automatic-timepieces and /collections/quartz-timepieces and 8 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 83 found) and read each the way a search engine does.

3 of 11 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 “Uncaught (in promise) TypeError: Cannot destructure property 'name' of 'e' as it is undefined.”.

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

1 link go through two or more redirects, for example https://sangininstruments.com/customer_authentication/redirect?locale=en&region_country=US.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

sangininstruments.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

sangininstruments.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

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

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.

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 250 words of visible text.

DMARC is set to p=none, so mail pretending to be sangininstruments.com is still delivered. Add a report address, check the reports, then move to quarantine.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads 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 16 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 21 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
