Website Testing from China – How It Works
See what users in China really experience when visiting your site
Our testing service measures how accessible and fast your website is when accessed from inside mainland China. Unlike typical monitoring tools that run from overseas or use VPNs, our tests are performed on real infrastructure located within China, providing results that reflect authentic user experience.
What We Test
Your website is analyzed across four layers, allowing us to identify exactly where any problem occurs:
| Layer | What It Checks | What It Tells You |
|---|---|---|
1 DNS Resolution | Can your domain be found by Chinese DNS servers? | Detects domain blocking or misconfiguration |
2 HTTP Connectivity | Can browsers connect to your server? | Identifies firewalls, SSL issues, or misconfigurations |
3 Network Diagnostics | (If HTTP fails) Can the network reach your IP? | Shows whether the issue is network- or application-level |
4 Browser Rendering | How your page loads in a real browser | Measures which resources fail, slow down, or block rendering |
This multi-layer approach helps us find the exact root cause of any accessibility or performance issue.
The Unified Reachability Score (0–100)
Every test produces a Reachability Score that summarizes how accessible your site is from China.
Connectivity
Can users reach your website? (DNS + HTTP)
Resource Loading
Do key images, scripts, and styles load correctly?
Performance
How quickly does your site become usable?
Example: A score of 78/100 means your site is partially accessible — users can reach it, but key features or visuals may not work properly.
Understanding the Score
Your Reachability Score provides a data-driven overview of your site's accessibility from China, but it doesn't represent a perfect measure of user perception.
What it tells you:
- • The technical reachability of your site through real China-based networks
- • How many resources load successfully and how fast
- • Where the main points of failure or slowdown occur
What it doesn't guarantee:
- • That every user in China will experience the same results
- • That a high score equals flawless usability
- • That a low score means the site is completely unreachable
Even though our methodology simulates real-world access as closely as possible, these are still automated tests. A site with a lower score may still feel usable if missing or slow resources are non-critical, while a site with a high score might still encounter localized issues depending on the user's ISP or region.
In short: the score measures objective accessibility and performance, not subjective perception — but it's a strong indicator of how real users will experience your site.
Score Interpretation
Our updated scoring model is designed to reflect real user experience more accurately. Scores now represent not just connectivity, but how usable your site actually feels from within mainland China.
| Score Range | Label & Status | What It Means for Users |
|---|---|---|
| 95–100 | Fully Accessible No meaningful barriers detected | The site behaves almost like a domestic Chinese website — fast, reliable, and fully functional. |
| 85–94 | Mostly Accessible Minor slowdowns or small third-party issues | The site is generally smooth and usable, with only occasional non-critical delays. |
| 70–84 | Partially Accessible Noticeable slowdowns or missing elements | The site loads but users may experience visible delays, broken features, or layout issues. |
| 50–69 | Degraded Accessibility Significant performance or functionality problems | Technically reachable, but frustrating to use — major features may not work properly. |
| 0–49 | Unreachable / Severely Limited Major connection or content failures | The site cannot be reliably accessed or rendered for most users in China. |
Common Issues We Help Identify
| Problem | Typical Cause | Recommended Fix |
|---|---|---|
| Slow or partial loading | CDN not optimized for China | Use China-based or globally distributed CDNs |
| Google Fonts / Analytics not loading | Blocked third-party services | Self-host or replace with China-friendly alternatives |
| DNS errors | DNS pollution or configuration issues | Use China DNS providers or optimize DNS setup |
| SSL/TLS handshake failures | Non-standard or untrusted certificate chains | Use globally recognized CAs |
| Incomplete page loads | Mixed blocked and unblocked resources | Replace or remove affected elements |
FAQ
Why is testing from China important?
Because tools outside China can't detect the DNS, routing, or filtering that affects users inside the country.
Do you use VPNs or simulated connections?
No. We test from real servers inside mainland China, ensuring authentic results.
What does the reachability score tell me?
It shows how easily Chinese users can reach and use your website — combining connectivity, loading success, and performance.
Can a low score still mean my site works fine?
Yes, in some cases. If the failing or slow resources aren't critical to user experience, your site may still feel fine to real users.
