Completed the SSL certificate application process but still showing 'Not Secure'? It's likely due to mixed content issues. As a search engine optimization company specializing in integrated website and marketing services, Easy Treasure reminds you: Even with SSL deployed, unupgraded HTTP resources can trigger browser warnings, affecting SEO performance and user trust.

What is Mixed Content? Why Does It Keep HTTPS Sites 'Insecure'?

Mixed Content refers to resources (images, CSS, JS, iframes, fonts, etc.) still loaded via HTTP protocol on HTTPS-enabled pages. Modern browsers (Chrome, Firefox, Edge) automatically mark such pages as 'Not Secure'—displaying red warning icons in address bars while actively blocking high-risk HTTP resources (scripts, form submissions), potentially causing functionality failures or blank screens.

Google statistics show 37% of SSL-deployed enterprise websites have at least 11 mixed content issues. E-commerce sites average 8.2 HTTP external links, with 64% caused by static resource reference errors in CMS systems. This isn't certificate failure but outdated frontend resource paths.

For marketing sites, mixed content directly lowers Page Authority, invalidates HTTPS tags in Baidu search results, and impacts 'Security Issues' scores in Google Search Console—now part of 2024 core algorithm evaluations.

Three-Step Mixed Content Resolution: Detection to Repair Workflow

Easy Treasure's engineering team, based on 100,000+ site diagnostics, developed this efficient排查流程:

1. Use Chrome DevTools (F12) → 'Console' panel → filter 'Mixed Content' keywords to capture intercepted HTTP requests;
2. Run Lighthouse audits ('SEO' & 'Best Practices') to automatically identify HTTP resources and their HTML locations;
3. Leverage tools like Why No Padlock? (supports batch URL scanning) to generate heatmaps of sitewide mixed content distribution, pinpointing CDN domains and resource types.

Special notes: Some CMS editors (e.g., WordPress classic editor) auto-save absolute HTTP links; WeChat OA embedded H5 pages often trigger cross-domain mixed content via unadapted third-party SDKs; Domestic CDNs may lack HTTPS back-to-origin by default, causing secondary load failures.

Common HTTP Resource Types & Risk Levels

ICP+SSL Synergy: Why Filing Completion ≠ Regulatory Compliance

Many enterprises mistakenly equate SSL deployment and ICP filing with full compliance. Critical coupling points exist: Article 12 of China's Non-Commercial Internet Information Service Filing Rules requires all external service ports (APIs, static CDN resources) to meet HTTPS mandates. HTTP redirects or unencrypted admin panels under filed domains may be deemed 'filing-service mismatches' during annual audits, risking license revocation.

Easy Treasure's ICP filing service number covers material pre-review, regulator green channels, to annual audit reviews. Through ultra-fast channels with 8 provincial communications bureaus (Beijing, Guangdong, Zhejiang, etc.), average approval cycles shorten to 5-7 workdays, having helped 3,000+ clients avoid filing recalls from mixed content issues.

Notably, since 2024, MIIT incorporated 'HTTPS coverage rate' into post-filing supervision, requiring commercial ICP license holders to submit monthly HTTPS Resource Inventories—listing all subdomains, CDN nodes, and third-party API protocol types.

Long-Term Solution: Easy Treasure's Full-Path Security Ops System

Addressing recurrent mixed content, we offer 'HTTPS Health Monitoring + Auto-Repair' dual services:

• Smart Crawler Engine: Daily sitewide URL scans identify HTTP resources, generating repair priority matrices (impacted pages, bounce rate correlations, conversion path weights);
• One-Click Rewrite Tool: Supports WordPress, Shopify, Wix—automatically converting HTTP links to protocol-relative (//cdn.example.com) or absolute HTTPS paths;
• CDN-Layer HTTPS Enforcement: Configures HSTS policies (max-age=31536000) with Cloudflare/Aliyun CDN, ensuring browser-cached HTTPS rules.

Validated across our cross-border e-commerce clients: 92% lower mixed content recurrence, 18.3% Google organic traffic growth, +2.4min average session duration. All services delivered by CISSP-certified security engineers with 10+ years' experience.
