HTTPS & Security Analyzer

Why It Matters

Mixed Content Undermines Your HTTPS Security and Affects Rankings

HTTPS is a confirmed Google ranking signal — but simply having an SSL certificate is not enough. Mixed content occurs when an HTTPS page loads resources (images, scripts, stylesheets) over HTTP. Modern browsers block or warn on mixed content, meaning your page's resources may fail to load for users — causing broken styling, non-functional JavaScript, and missing images.

Mixed content is particularly common after migrations from HTTP to HTTPS — hardcoded HTTP URLs in templates, CMS content, and third-party embeds don't update automatically. Sites that migrated months or years ago may still have hundreds of mixed content issues they're unaware of, causing browser "Not Secure" indicators on affected pages.

TechySEO checks every page for mixed content signals and HTTPS configuration issues — giving you a complete remediation list rather than just a flag that "issues exist."

⚠️

Mixed Content Warnings

HTTP resources on HTTPS pages trigger browser security warnings that undermine user trust and cause resource loading failures.

🔓

Insecure Form Actions

Forms submitting to HTTP endpoints expose user data to interception — a critical security issue, not just an SEO concern.

🔄

Missing HTTP→HTTPS Redirects

Pages accessible over HTTP without redirect leak link equity and create duplicate content between HTTP and HTTPS versions.

📡

HTTP External Resources

Third-party scripts, fonts, and embeds loaded over HTTP create mixed content on pages that otherwise have clean HTTPS.

What It Checks

6 Security & HTTPS Issue Types

Comprehensive HTTPS and mixed content auditing across your entire site — from internal links to external resource loading.

🔗

HTTP Links on HTTPS Pages

Internal and external links using HTTP on pages served over HTTPS — not mixed content itself, but a hygiene signal and potential redirect chain source that should be updated to HTTPS.

✅

HTTPS Link Verification

Confirms pages correctly use HTTPS links for all internal navigation — providing a positive baseline of security-compliant pages alongside the issues list.

⚠️

Mixed Content Pages

Pages that load active mixed content — scripts or stylesheets over HTTP on an HTTPS page — which browsers block entirely, causing functionality failures visible to users.

📡

HTTP External Resources

Third-party scripts, fonts, iframes, and API calls loaded via HTTP on HTTPS pages. Includes the resource URL and the pages affected — for contacting external providers about HTTPS support.

📝

Insecure Form Actions

Forms on HTTPS pages with action attributes pointing to HTTP URLs — a critical security issue that exposes form data to man-in-the-middle interception. Flagged as highest severity.

🔄

HTTP to HTTPS Redirect Verification

Verifies that HTTP versions of your key pages properly redirect to HTTPS via 301 — ensuring no duplicate content exists between HTTP and HTTPS versions and all link equity flows correctly.

How It Works

Continuous HTTPS Security Monitoring

Crawler Analyzes All Page Resources

For each crawled page, TechySEO analyzes all resource references in the HTML — script src, link href, img src, form action, iframe src, and anchor href — recording the protocol (HTTP or HTTPS) for each.

HTTP vs HTTPS Protocol Classified

Each resource is classified by type (active mixed content vs passive) and severity — active mixed content (scripts, stylesheets) is blocked by browsers and flagged critical; passive mixed content (images) generates warnings and is flagged high.

HTTP Redirect Paths Verified

TechySEO sends HTTP requests to all known page URLs and verifies they return 301 redirects to the HTTPS version — catching pages where the HTTP→HTTPS redirect is missing or returning a soft 200 response.

Issues Reported With Fix Context

Each issue includes the page URL, the specific insecure resource or link, the issue type, and the recommended fix — whether updating a hardcoded URL, contacting an external provider, or updating server redirect rules.

Use Cases

Security Analysis for Every Stage

HTTPS Migrations

Find Every Mixed Content Issue Post-Migration

After migrating from HTTP to HTTPS, TechySEO's security audit identifies every remaining hardcoded HTTP reference — in templates, CMS content, third-party scripts, and external embeds — so your migration is genuinely complete before you start link building on the new HTTPS site.

eCommerce

Ensure Payment Pages Are Fully Secure

Checkout and payment pages must be completely free of mixed content — any HTTP resource on a payment page triggers browser security warnings that destroy purchase conversion. TechySEO monitors these critical pages continuously, alerting instantly if any mixed content appears after a template or plugin update.

Enterprise

Audit HTTPS Compliance Across Subdomains

Large organizations with multiple subdomains, regional sites, and microsites often have inconsistent HTTPS implementation. TechySEO's security analysis provides a unified view of HTTPS compliance across all crawled domains — identifying the properties and page types most in need of remediation.

FAQ

Security Analysis — FAQs

What exactly is mixed content?

Mixed content occurs when an HTTPS page loads resources via HTTP. There are two types: active mixed content (scripts, stylesheets, iframes) which browsers block entirely — causing JavaScript errors and broken styling — and passive mixed content (images, audio, video) which browsers may load with a security warning. Modern browsers are increasingly blocking passive mixed content as well. TechySEO flags both types, with active mixed content marked as critical severity.

Does HTTPS directly affect Google rankings?

Yes — HTTPS has been a confirmed Google ranking signal since 2014. However, it's a lightweight signal; it's unlikely to overcome major content or authority disadvantages. More importantly, HTTPS affects user trust signals: browser security warnings on non-HTTPS or mixed content pages increase bounce rates and reduce time on page — behavioral signals that can indirectly affect rankings.

I have an SSL certificate but my site still has mixed content — why?

An SSL certificate makes your server capable of serving content over HTTPS — but it doesn't automatically update hardcoded HTTP URLs in your HTML, CSS, JavaScript, or database content. Old pages created before the migration, CMS content with absolute HTTP URLs, and third-party embeds referencing HTTP endpoints will continue to generate mixed content even after the SSL certificate is installed. TechySEO finds all these remaining references for you to update.

How do I fix mixed content?

For internal resources: update the hardcoded HTTP URLs in your templates, CMS, and database to use HTTPS or protocol-relative URLs (//). For external resources: contact the third-party provider to confirm they support HTTPS and update your references to their HTTPS endpoint. For some third-party embeds that don't support HTTPS, removal or replacement is the only option. TechySEO's export categorizes issues by internal vs external and by severity — helping you prioritize the fix effort.

Does TechySEO check beyond mixed content for security?

TechySEO's security analysis focuses on SEO-impacting security issues — primarily mixed content, HTTPS configuration, and insecure form actions. It is not a full security scanner (it doesn't scan for XSS, SQL injection, or application vulnerabilities). For comprehensive security scanning, use dedicated tools like OWASP ZAP or commercial vulnerability scanners alongside TechySEO's SEO-focused security checks.
