Render-blocking requests
2.1 s10 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.1 s.
Use efficient cache lifetimes
50 ms · 5.3 MB25 files are served with short cache lifetimes, so returning visitors download them again (5.3 MB).
Improve image delivery
3.5 MB7 images could be 3.5 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.
Mobile performance score: 88
88/100Your mobile performance score is 88. Pages that score under 90 lose visitors before the first paint.
6 third-party services on the page
6 third-party services load with your homepage (bcebos.com, Baidu Analytics and 51.la and others), adding 5.3 MB and 174 ms of main-thread time.
adcomma.cn adds 0 ms
0 msadcomma.cn costs a phone 0 ms of main-thread work and 4.9 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.
Reduce unused JavaScript
300 ms · 200 KiBAbout 200 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.
6 long tasks on the main thread
6 long tasks block the main thread while loading, the longest for 112 ms. During a long task the page ignores taps.
Legacy JavaScript
35 KiBPolyfills for old browsers add 35 KiB JavaScript that modern phones do not need.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.
Forced reflow
Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.
2 checks passed
Main-thread work: 1.7 s
A phone's processor spends 1.7 s on main-thread work while loading, 623 ms of it running JavaScript. That is comfortably low.
Server response: 2 ms
2 msYour server sent the HTML in 2 ms, well inside Google's 600 ms guideline.
Core Web Vitals
Speed Index: 23.4 s
23.4 sVisually, the page fills in at 23.4 s (Speed Index). Good is under 3.4 s.
Time to Interactive: 12.0 s
12.0 sThe page becomes fully interactive after 12.0 s. Good is under 3.8 s.
12 images without width and height
12 images have no width and height attributes, so the layout jumps as each one loads.
Not enough real-visitor data yet
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.
4 checks passed
First Contentful Paint: 1.6 s
1.6 sThe first text or image appears after 1.6 s, inside the 1.8 s “good” threshold.
Largest Contentful Paint: 2.3 s
2.3 sYour largest element renders in 2.3 s on a phone, inside Google's 2.5 s “good” threshold. The largest element is the text “AI，让我们更高效”.
Cumulative Layout Shift: 0
0The layout barely moves while loading (CLS 0, good is under 0.1).
Total Blocking Time: 62 ms
62 msScripts block the page for only 62 ms while loading. Good is under 200 ms.
Images and page weight
Page weight: 10.2 MB in 59 requests
10.2 MBYour homepage downloads 10.2 MB in 59 requests on a phone: media 5.1 MB (6), images 4.6 MB (25) and scripts 502 KiB (15). Under 2 MB keeps phones on slow connections fast.
About 2.9 g of CO₂ per visit
2.90 gBy the Sustainable Web Design model, a visit to your homepage emits about 2.90 g of CO₂e: 347.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
3 checks passed
Images use modern formats
Every sizeable image is WebP, AVIF or SVG.
Images load when needed
Images below the first screen wait until the visitor scrolls to them.
Images are sized for phones
No image is downloaded at more than three times the size it is drawn on a phone.
Accessibility
5 text elements with low contrast
5 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
2 tap targets too small
2 tap targets are too small or too close together to hit reliably with a finger.
7 images without alt text
7 images have no alt text, which hurts accessibility and image search.
All page content should be contained by landmarks (19 elements)
All page content should be contained by landmarks: 19 elements on the page fail this check, rated moderate by axe-core.
No main landmark
The page has no <main> landmark, so screen-reader users cannot jump straight to the content.
Zoom is disabled
The viewport tag blocks pinch-zoom, which low-vision visitors rely on.
Page should contain a level-one heading (1 element)
Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.
3 links without text
3 visible links have no text or label, so screen readers cannot say where they go.
1 form field without a label
1 form field has no label, so screen readers announce an empty box and autofill guesses.
Alternative text of images should not be repeated as text (6 elements)
Alternative text of images should not be repeated as text: 6 elements on the page fail this check, rated minor by axe-core.

30 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 39 WCAG 2.2 A/AA and best-practice rules on the phone render: 30 passed and 9 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
No H1 headline
There is no <h1>, so neither visitors nor Google get a clear main headline.
Title is short (15 characters)
Your title is only 15 characters: “特变电工新能源_特变电工新能源”. Between 30 and 65 characters leaves room to say what you do and for whom.
No structured data
No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.
No canonical URL
No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.
Meta description is long (173 characters)
Your meta description is 173 characters; Google truncates after about 160, so the end of your pitch is cut.
No social preview image
No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.
No robots.txt
There is no robots.txt at sunoasis.com.cn/robots.txt, the first file search crawlers ask for.
7 links crawlers can't follow
7 links have no real href, so search engines can't follow them.
No favicon declared
No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.
No X (Twitter) card tag
No twitter:card tag. X falls back to Open Graph, which is incomplete here.
86 internal links, 41 external
The homepage links to 86 pages on sunoasis.com.cn and 41 external pages.

XML sitemap found
Your XML sitemap is reachable at https://www.sunoasis.com.cn/sitemap.xml.
AI search readiness
No Organization structured data
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.
No llms.txt
There is no https://www.sunoasis.com.cn/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.
1 checks passed
AI answer engines may read the site
There is no robots.txt, so nothing stops the crawlers behind ChatGPT search, Claude and Perplexity from reading the site and cite it in answers.
Other pages
2 pages share a title
https://www.sunoasis.com.cn/Product-ESS and https://www.sunoasis.com.cn/Solution-ESS-S all use the title “储能系统_特变电工新能源”. Search engines can't tell which page to show for a search, so each competes with the others.
12 pages share a meta description
https://www.sunoasis.com.cn/Product-PV, https://www.sunoasis.com.cn/Product-ESS, https://www.sunoasis.com.cn/Product-DC, https://www.sunoasis.com.cn/Product-Statcom, https://www.sunoasis.com.cn/TB-eCloud and https://www.sunoasis.com.cn/Solution and 6 others use the same meta description. A description written for each page earns more clicks.
12 pages without an H1
https://www.sunoasis.com.cn/Product-PV, https://www.sunoasis.com.cn/Product-ESS, https://www.sunoasis.com.cn/Product-DC, https://www.sunoasis.com.cn/Product-Statcom, https://www.sunoasis.com.cn/TB-eCloud and https://www.sunoasis.com.cn/Solution and 6 others have no <h1> headline, so visitors and search engines get no clear main topic.
12 pages with very little text
https://www.sunoasis.com.cn/Product-PV, https://www.sunoasis.com.cn/Product-ESS, https://www.sunoasis.com.cn/Product-DC, https://www.sunoasis.com.cn/Product-Statcom, https://www.sunoasis.com.cn/TB-eCloud and https://www.sunoasis.com.cn/Solution 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.
6 pages slow to respond
https://www.sunoasis.com.cn/Product-ESS, https://www.sunoasis.com.cn/Product-DC, https://www.sunoasis.com.cn/Product-Statcom, https://www.sunoasis.com.cn/TB-eCloud, https://www.sunoasis.com.cn/Solution and https://www.sunoasis.com.cn/Solution-SVG took over 3 s to send their HTML from our server.

Content and conversion
No call to action on the first screen
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 calls to action
We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.
No social proof
No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.
No analytics detected
No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.
Only about 31 words
The homepage has only about 31 words of visible text; thin pages give Google and first-time buyers little to go on.
No risk reducer
No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.
