HTTPS & Website Security
Securing your website with SSL/TLS encryption to protect user data and satisfy Google's ranking requirements.
The Definition
HTTPS (Hypertext Transfer Protocol Secure) encrypts data between a user's browser and your web server using SSL/TLS certificates. Website security for SEO also includes proper security headers (HSTS, CSP, X-Frame-Options), mixed content prevention, and certificate validity monitoring.
Why It Matters
HTTPS has been a Google ranking signal since 2014. Browsers flag HTTP sites as 'Not Secure,' which destroys user trust. Beyond rankings, security vulnerabilities can lead to your site being flagged as malicious and removed from search results entirely.
Best Practices
Redirect all HTTP URLs to HTTPS with 301 permanent redirects — do not serve content on both protocols
Implement HSTS (HTTP Strict Transport Security) headers to prevent downgrade attacks and enforce HTTPS
Audit for mixed content issues where HTTPS pages load HTTP resources (images, scripts, stylesheets)
Monitor SSL certificate expiration dates and set up automated renewal with Let us Encrypt or your CA provider
Add security headers: Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, Referrer-Policy
Ensure internal links and canonical tags use HTTPS URLs, not HTTP
Mistakes to Avoid
- 1
Letting SSL certificates expire, which shows browser security warnings and immediately destroys user trust
- 2
Not updating internal links from HTTP to HTTPS after migration, creating unnecessary redirect chains
- 3
Missing mixed content issues where secure pages load insecure resources, triggering browser warnings
- 4
Forgetting to update canonical tags, sitemap URLs, and hreflang tags to HTTPS after migration
Audit Checks
How Digispot AI identifies and fixes related issues
Website is not served over HTTPS
Impact: Data transmission is not encrypted, vulnerable to man-in-the-middle attacks
Install SSL certificate and enforce HTTPS
Page contains mixed (HTTP/HTTPS) content
Impact: Reduces security and triggers browser warnings
Update all resource references to use HTTPS
SSL certificate has expired or is expiring very soon (within 14 days)
Impact: Browsers will show security warnings, potentially blocking access
Renew SSL certificate immediately
Self-signed SSL certificate detected
Impact: Browsers will show security warnings and may block access, reducing user trust
Replace with a certificate from a trusted Certificate Authority (CA)
SSL certificate does not match the domain name
Impact: Browsers will show security warnings and may block access
Install a certificate that matches the domain name or update certificate configuration
SSL certificate has invalid date range (not yet valid or already expired)
Impact: Certificate will not be trusted, browsers will show security warnings
Check system clock and certificate validity dates, renew if necessary
