About the HTTPS & Mixed Content Checker
The HTTPS & Mixed Content Checker from SEOAegis scans web pages to verify they load securely over HTTPS
and flags any insecure assets (http://) that can break browser padlocks, block resources, or hurt SEO and Core Web Vitals.
It’s ideal for SEOs, developers, and security-conscious site owners who want a fully secure browsing experience for users.
The tool inspects all linked resources—images, scripts, stylesheets, iframes, videos, embeds, and forms—and reports mixed content issues.
By fixing these, you protect your visitors, maintain search ranking signals, and meet modern security standards.
Key Features
- Scans all asset types including images, CSS, JavaScript, iframes, audio/video, embeds, and forms.
- Counts total mixed content issues and displays up to 5 example offenders per page.
- Checks each asset’s protocol to confirm HTTPS compliance.
- Exports a clean CSV for developer review and quick fixes.
Why Mixed Content Hurts SEO & UX
- Breaks security padlock: Users see “Not Secure” warnings, which can reduce trust and conversions.
- Blocks scripts and styles: Modern browsers may block insecure resources, breaking functionality or layout.
- Hurts Core Web Vitals: Blocked or delayed assets can slow load times and increase layout shifts.
- Impacts rankings: HTTPS is a confirmed Google ranking signal; mixed content undermines it.
When to Use This Tool
- After an HTTP→HTTPS migration to ensure all resources are updated.
- During SEO audits to find hidden mixed content issues.
- Before launching new designs or templates that may include legacy HTTP assets.
- As part of security hardening for eCommerce and login-protected sites.
Pro Tip: Always use protocol-relative URLs (//example.com/script.js) or direct HTTPS links for CDNs and embedded resources to avoid triggering mixed content warnings.
