newdartslife.com website review

32 images could be 3.1 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.6 s faster on a phone.

36 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.8 s.

About 424 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.5 s faster on a phone.

Your mobile performance score is 41. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

156 files are served with short cache lifetimes, so returning visitors download them again (816 KiB).

8 third-party services load with your homepage (Google/Doubleclick Ads, Google Tag Manager and Google FundingChoices and others), adding 952 KiB and 692 ms of main-thread time.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 750 ms).

Google/Doubleclick Ads costs a phone 430 ms of main-thread work and 467 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.

A phone's processor spends 3.3 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 1,725 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

6 long tasks block the main thread while loading, the longest for 164 ms. During a long task the page ignores taps.

About 24 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.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 9.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “VOL.23-Web 一番流れるTop Page”.

The layout shifts by 0.494 while loading, so content jumps under the reader's thumb. Good is under 0.1.

The page becomes fully interactive after 9.6 s. Good is under 3.8 s.

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

Real visitors wait 984 ms for your server to start answering (75th percentile). Good is under 800 ms.

The first text or image appears after 2.1 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 282 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 67 ms to 71 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.7 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 8.8 MB in 327 requests on a phone: images 6.1 MB (209), media 1.1 MB (1) and scripts 1,010 KiB (42). Under 2 MB keeps phones on slow connections fast.

40 images (3.0 MB) 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.

2 images further down the page (138 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 2.48 g of CO₂e: 297.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

2 tap targets are too small or too close together to hit reliably with a finger.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 3 elements on the page fail this check, rated moderate by axe-core.

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

Banner landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Contentinfo landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Document should not have more than one banner landmark: 1 element on the page fails this check, rated moderate by axe-core.

Document should not have more than one contentinfo landmark: 1 element on the page fails this check, rated moderate by axe-core.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

ARIA role should be appropriate for the element: 78 elements on the page fail this check, rated minor by axe-core.

There is no <h1>, so neither visitors nor Google get a clear main headline.

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

The homepage links to 301 pages on newdartslife.com and 9 external pages.

There is no https://newdartslife.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.

https://newdartslife.com/column_cat/sakai, https://newdartslife.com/column_cat/ktm, https://newdartslife.com/column_cat/jinta and https://newdartslife.com/column_cat/igarashi have no meta description, so Google writes the search snippet from whatever text it finds.

https://newdartslife.com/contact, https://newdartslife.com/sponser, https://newdartslife.com/news-info and https://newdartslife.com/shop-bar-guide have no <h1> headline, so visitors and search engines get no clear main topic.

https://newdartslife.com/shop-bar-guide and https://newdartslife.com/japanese-player-int took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 106 found) and read each the way a search engine does.

16 of 56 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

1 image is served at too low a resolution for sharp phone screens.

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.

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.

The homepage carries about 389 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, 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 8 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 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
