HTTPS & Mixed Content Check
Ensure your website is fully secure. Our dual-layer scanner verifies your SSL certificate validity and detects specific "Mixed Content" errors that break the green padlock.
We check for valid certificates, 301 redirects, and insecure HTTP resources.
Auditing Security Protocols...
This involves an SSL handshake and a full DOM scan.
Please wait while we connect to the server.
Security Audit Report
The SERPInsight HTTPS Scanner
HTTPS is a confirmed Google ranking signal and a critical trust factor for users. However, simply installing an SSL certificate isn't enough. If your secure page loads resources (images, scripts, CSS) over insecure HTTP, browsers will block the padlock icon.
The SERPInsight HTTPS Scanner performs a dual-layer audit. We first verify the server-level certificate handshake, and then we parse the page code to find "Mixed Content" vulnerabilities that other tools miss.
How our tool works
-
1
Input Target URL
Enter your website URL. We support both HTTP and HTTPS inputs to test redirect logic.
-
2
SSL Handshake
We connect to Port 443 to retrieve the certificate issuer, expiration date, and TLS protocol version.
-
3
Deep DOM Scan
We download the HTML and scan every image, script, and iframe tag to detect insecure HTTP links.
Understanding Our Metrics
The certificate is issued by a trusted authority (e.g., Let's Encrypt) and has not expired.
Occurs when a secure page loads insecure files (http://), causing browser warnings.
The server correctly uses a 301 Redirect to send all http:// traffic to https://.
Indicates which security protocol (TLS 1.2 or 1.3) is being used for the connection.
Frequently Asked Questions
Why does my site say "Not Secure" even with SSL?
http://your-site.com/logo.png, browsers consider the entire page compromised. Our tool identifies these exact files.
What is "Force HTTPS"?
http://example.com, your server should automatically 301 Redirect them to https://example.com.
Does HTTPS affect SEO rankings?
Why use SERPInsight?
Professional-grade diagnostics for serious SEOs.
Dual-Layer Audit
Most tools only check the certificate validity. We check the certificate *and* scan the HTML code for insecure resources in one go.
Native PHP Scanning
Built with native PHP streams and DOMDocument parsing for lightning-fast results without relying on slow third-party APIs.
Pinpoint Accuracy
We don't just say "Failed." We give you the exact URL of every single image, script, or iframe that is causing the security warning.
Private & Secure
We process the scan in real-time and do not store your data or crawl history. Your analysis remains completely private.
