arrowupskill.com website review

87 files are served with short cache lifetimes, so returning visitors download them again (7.1 MB).

8 third-party services load with your homepage (7sea.cc, 126.net and aliyuncs.com and others), adding 2.4 MB and 1.8 s of main-thread time.

12 images could be 1.4 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Your mobile performance score is 76. Pages that score under 90 lose visitors before the first paint.

7sea.cc costs a phone 734 ms of main-thread work and 1.1 MB 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.

About 835 KiB of JavaScript is downloaded but never used on this page.

126.net costs a phone 683 ms of main-thread work and 707 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 3.8 s on main-thread work while loading, 2.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 1,711 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 191 KiB of CSS is downloaded but never applied on this page.

13 long tasks block the main thread while loading, the longest for 144 ms. During a long task the page ignores taps.

35 KiB could be saved by minifying CSS.

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.

Visually, the page fills in at 15.6 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 28.2 s. Good is under 3.8 s.

The first text or image appears after 2.8 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 274 ms in total while the page loads. Good is under 200 ms.

Your largest element takes 2.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “JDB电子夺宝官网”. Most of its time is element render delay (3.3 s).

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 9.1 MB in 181 requests on a phone: media 3.3 MB (2), scripts 2.7 MB (52) and images 2.7 MB (52). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 2.58 g of CO₂e: 309.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Some list items are not inside a list.

Some lists contain elements other than list items, which screen readers announce wrongly.

3 frames have no title, so screen-reader users cannot tell what they contain.

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

All page content should be contained by landmarks: 6 elements on the page fail this check, rated moderate by axe-core.

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

Your title is only 14 characters: “jdb电子(中国)·官方网站”. Between 30 and 65 characters leaves room to say what you do and for whom.

Structured data found (untyped) but with 2 problems, for example “ld+json block 1 is not valid JSON (Bad control character in string literal in JSON at position )”.

Your hreflang tags are invalid, so Google may show the wrong language version.

The homepage links to 369 pages on arrowupskill.com and 2 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.

Your homepage links to https://arrowupskill.com/ppzx, which answers with an error. Visitors hit a dead end and search engines drop it.

Your homepage links to 14 pages by a URL that isn't their canonical one, for example https://arrowupskill.com/zzxt, whose canonical is https://arrowupskill.com/zzxt/JDB%E7%94%B5%E5%AD%90%E5%A4%BA%E5%AE%9D%E5%AE%98%E7%BD%91. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://arrowupskill.com/zzxt, https://arrowupskill.com/zmyq, https://arrowupskill.com/sxxl, https://arrowupskill.com/zyfz, https://arrowupskill.com/zzry and https://arrowupskill.com/winlong and 8 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.

https://arrowupskill.com/yfxt and https://arrowupskill.com/ppjj took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 58 found) and read each the way a search engine does.

33 of 55 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.”).

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

The page has no <!DOCTYPE html>, so browsers render it in quirks mode.

Chrome logged issues while loading the page (“Cookie”).

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.

Social proof on the homepage: “over 6000 customers”. Pairing it with named testimonials or customer logos makes it far more convincing.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

The homepage has only about 151 words of visible text; thin pages give Google and first-time buyers little to go on.

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.

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 9 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
