Security tools

How does your site compare?

95% of Google's top-ranking pages use HTTPS. Sites without SSL see 20-30% lower trust ratings from visitors.

Based on analysis of HTTPS adoption and security header presence across top-ranking websites.
Your site uses HTTPS with a valid certificate, no mixed content, and at least 4 of 6 recommended security headers.

How to fix this

Enable HTTPS with a valid SSL certificate, fix mixed content, and add security headers.

  1. 1Install an SSL certificate. Most hosts offer free SSL via Let's Encrypt or Cloudflare.
  2. 2Redirect all HTTP traffic to HTTPS using a 301 redirect.
  3. 3Fix mixed content: search your HTML/CSS for "http://" URLs and change them to "https://".
  4. 4Add HSTS header: Strict-Transport-Security: max-age=31536000; includeSubDomains
  5. 5Add CSP header to control which resources can load on your pages.
  6. 6Add X-Frame-Options: DENY to prevent your site from being embedded in malicious iframes.

Frequently Asked Questions

What is SSL/TLS?
SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) encrypt data between your visitor's browser and your server. This prevents eavesdropping and tampering with data in transit.
Do I need SSL for my website?
Absolutely. Without SSL, browsers show "Not Secure" warnings, Google penalizes your rankings, and visitor trust plummets. Most hosting providers offer free SSL via Let's Encrypt.
What are security headers?
HTTP security headers are instructions your server sends to browsers about how to handle your site's content. Key headers include HSTS (force HTTPS), CSP (prevent XSS), and X-Frame-Options (prevent clickjacking).
What is mixed content?
Mixed content occurs when an HTTPS page loads resources (images, scripts, stylesheets) over HTTP. This weakens security and triggers browser warnings. Update all resource URLs to use https://.
