onsensecret.com website review

About 1.4 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

8 third-party services load with your homepage (Google Tag Manager, vitals.app and rebuyengine.com and others), adding 2.4 MB and 928 ms of main-thread time.

Your mobile performance score is 66. Pages that score under 90 lose visitors before the first paint.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 500 ms.

Google Tag Manager costs a phone 377 ms of main-thread work and 657 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.

16 images could be 350 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

A phone's processor spends 3.5 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 2,941 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

vitals.app costs a phone 131 ms of main-thread work and 318 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.

rebuyengine.com costs a phone 104 ms of main-thread work and 298 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.

tidio.co costs a phone 59 ms of main-thread work and 515 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 53 ms of main-thread work and 363 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.

18 files are served with short cache lifetimes, so returning visitors download them again (218 KiB).

63 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 150 ms faster on a phone.

7 long tasks block the main thread while loading, the longest for 146 ms. During a long task the page ignores taps.

Polyfills for old browsers add 47 KiB JavaScript that modern phones do not need.

About 33 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

3 KiB could be saved by minifying JavaScript.

The page becomes fully interactive after 25.8 s. Good is under 3.8 s.

Your largest element takes 6.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

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

Scripts block taps and scrolling for 370 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 4.2 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 138 ms to 171 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.9 s to 1.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 10.8 MB in 339 requests on a phone: media 6.0 MB (4), scripts 2.7 MB (110) and images 931 KiB (47). Under 2 MB keeps phones on slow connections fast.

15 images further down the page (795 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

4 images (443 KiB) 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.

By the Sustainable Web Design model, a visit to your homepage emits about 3.06 g of CO₂e: 367.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 element hidden from screen readers can still receive keyboard focus.

Summary elements must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

10 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.

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

Elements with visible text labels do not have matching accessible names. (2 elements).

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

Your <h1> is empty.

The homepage links to 168 pages on onsensecret.com and 16 external pages.

There is no https://www.onsensecret.com/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.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://www.onsensecret.com/collections/body-care/products/advanced-reboot-kit, whose canonical is https://www.onsensecret.com/products/advanced-reboot-kit-japanese-hot-spring-minerals. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 48 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

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

The homepage carries about 2,382 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 3 mores (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 27 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 49 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
