What is SSL/HTTPS?
SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are protocols for establishing authenticated and encrypted links between networked computers. In SEO terms, HTTPS means your site is secure and trustworthy.
- Encryption: Protects data (passwords, credit cards) from being intercepted by attackers.
- Authentication: Confirms that the server the user is talking to is actually who they claim to be.
- Integrity: Ensures that the data sent between the browser and server hasn't been tampered with.
Why Security Matters for SEO
Since 2014, Google has used HTTPS as a ranking signal. Beyond direct rankings, security is about user trust. Browsers like Chrome mark HTTP sites as "Not Secure," which can trigger a 40-60% drop in conversion rates as users flee the site.
HTTPS is a requirement for modern browser features like Geolocation, Service Workers, and HTTP/2. Without a valid SSL certificate, you're not just risking security; you're blocking your own site's performance.
Best Practices for SSL/HTTPS
Keeping your site secure requires more than just installing a certificate once. Follow these best practices:
- Automate Renewals: Use services like Let's Encrypt with auto-renewal scripts to avoid the #1 cause of SSL failure: manual oversight.
- Full Site HTTPS: Don't just secure the login page. Redirect all HTTP traffic to HTTPS using permanent 301 redirects.
- Fix Mixed Content: Ensure every image, script, and CSS file on your page is loaded via HTTPS. One HTTP file can break the security padlock.
- HSTS: Enable HTTP Strict Transport Security (HSTS) to tell browsers to ALWAYS use HTTPS for your domain.
