SSL certificates are no longer optional for WordPress sites. Google penalizes HTTP sites in search rankings, browsers display scary "Not Secure" warnings, and visitors bounce when they don't see the padlock. But should you pay extra for SSL? Absolutely not.
This guide explains everything you need to know about SSL for WordPress, including how to get it free, the benefits of TLS 1.3, and which hosts still charge extra for what should be included.
What Is SSL and Why Does Your WordPress Site Need It?
SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) encrypt the connection between your website and your visitors. When someone visits your WordPress site over HTTPS, all data - including login credentials, form submissions, and page content - is encrypted end-to-end.
The Padlock That Builds Trust
You've seen the padlock icon in your browser's address bar. That small symbol has a massive impact:
- Google Ranking Factor: HTTPS is a confirmed ranking signal. Sites with SSL rank higher than those without.
- Browser Warnings: Chrome, Firefox, and Safari all display "Not Secure" warnings on HTTP pages, especially those with forms.
- User Trust: 84% of users would abandon a purchase if the site wasn't secure.
- Data Protection: Encryption prevents attackers from intercepting sensitive data on public WiFi.
- Compliance: PCI-DSS requires HTTPS for any site handling payment information.
Important: HTTP sites can have login credentials, admin passwords, and customer data intercepted by anyone on the same network. Never log into wp-admin over HTTP on public WiFi.
SSL vs TLS: What's the Difference?
When people say "SSL certificate," they're usually talking about TLS. Here's the history:
- SSL 2.0 (1995): First public version - now deprecated and insecure
- SSL 3.0 (1996): Improved but still vulnerable - disabled in modern browsers
- TLS 1.0 (1999): First TLS version - deprecated as of 2020
- TLS 1.1 (2006): Minor improvements - also deprecated
- TLS 1.2 (2008): Widely used today - still secure
- TLS 1.3 (2018): Current standard - fastest and most secure
Modern hosting should support TLS 1.2 and TLS 1.3, with older versions disabled. MojoShine enforces TLS 1.3 for all sites, providing the best security and performance.
Why TLS 1.3 Matters for WordPress Performance
TLS 1.3 isn't just more secure - it's significantly faster. Here's why it improves your WordPress site's performance:
Faster Handshake (0-RTT)
TLS 1.3 reduces the initial connection from 2 round trips to 1 (or 0 for returning visitors). This can save 100-300ms per page load.
Reduced Latency
Fewer round trips means faster Time to First Byte (TTFB), improving Core Web Vitals and user experience.
Stronger Encryption
TLS 1.3 removes outdated cipher suites and uses only modern, secure algorithms like ChaCha20 and AES-GCM.
Forward Secrecy by Default
Every connection uses unique keys, so even if your private key is compromised, past traffic can't be decrypted.
Real-World Impact: Sites using TLS 1.3 see 10-40% faster connection times compared to TLS 1.2. For WordPress sites, this translates to better Core Web Vitals scores and improved search rankings.
Free SSL vs Paid SSL: What's the Difference?
There are three main types of SSL certificates:
Domain Validation (DV) - Usually Free
DV certificates verify you own the domain. They provide the same encryption as expensive certificates and are perfect for most WordPress sites. Let's Encrypt issues millions of free DV certificates.
Organization Validation (OV) - $50-200/year
OV certificates verify your business exists. They show organization details in the certificate, but visitors see the same padlock as DV certificates.
Extended Validation (EV) - $100-500/year
EV certificates involve extensive business verification. They used to display a green bar with company name, but modern browsers no longer show this. The visual difference is gone.
Bottom Line: For encryption, all certificate types are identical. Free DV certificates from Let's Encrypt provide the same security as $500 EV certificates. The encryption is the same - only the verification process differs.
WordPress Hosting SSL Comparison
Not all WordPress hosts include free SSL. Here's how the major providers compare:
| Host | Free SSL | TLS 1.3 | Auto-Renewal | Custom Domains |
|---|---|---|---|---|
| MojoShine | Included | Yes | Automatic | Free SSL |
| WP Engine | Included | Yes | Automatic | Free SSL |
| Kinsta | Included | Yes | Automatic | Free SSL |
| Bluehost | Included | TLS 1.2 | Automatic | Free SSL |
| GoDaddy | $75/year | TLS 1.2 | Automatic | Extra cost |
| HostGator | Included | TLS 1.2 | Automatic | Free SSL |
Premium managed WordPress hosts like MojoShine, WP Engine, and Kinsta all include free SSL with automatic renewal. Budget hosts vary - some include it, some charge extra.
How MojoShine Handles SSL
At MojoShine, SSL is completely automated. Here's what happens when you create a site:
- Instant Certificate: SSL certificate is provisioned automatically during site creation
- TLS 1.3 Default: All sites use TLS 1.3 with the most secure cipher suites
- HTTPS Redirect: HTTP requests are automatically redirected to HTTPS
- Auto-Renewal: Certificates renew automatically before expiration
- Custom Domains: Add your own domain and get free SSL through Cloudflare for SaaS
You never have to think about SSL. It just works.
Get Free SSL with Your WordPress Site

Start Free TrialSetting Up SSL on WordPress
If you're on a host with free SSL, here's how to ensure your WordPress site uses it properly:
1. Update WordPress URLs
Go to Settings → General and ensure both "WordPress Address" and "Site Address" use https:// instead of http://.
2. Force HTTPS Redirects
Add this to your .htaccess file (Apache) or configure your host's redirect settings:
SSL Configuration Checklist
- WordPress URLs use https://
- HTTP redirects to HTTPS
- HSTS header enabled
- Mixed content errors fixed
- Certificate auto-renewal configured
- TLS 1.2+ enforced
3. Fix Mixed Content
Mixed content occurs when HTTPS pages load HTTP resources (images, scripts, stylesheets). Use a plugin like "Better Search Replace" to update all URLs in your database from http:// to https://.
4. Enable HSTS
HTTP Strict Transport Security tells browsers to always use HTTPS. Modern hosts enable this automatically. It prevents downgrade attacks where attackers force your site to load over HTTP.
Testing Your SSL Configuration
After setting up SSL, verify it's working correctly:
- SSL Labs Test: Use SSL Labs to get a grade (aim for A or A+)
- Browser Check: Visit your site and look for the padlock - click it to view certificate details
- Mixed Content: Open browser DevTools (F12) → Console to check for mixed content warnings
- Security Headers: Use SecurityHeaders.com to check HSTS and other headers
MojoShine Sites: All sites automatically receive an A+ rating on SSL Labs with TLS 1.3, HSTS, and secure cipher configuration out of the box.
Common SSL Problems and Solutions
Certificate Expired
Free Let's Encrypt certificates expire every 90 days. Good hosts renew them automatically. If yours expired, your host's renewal process failed - contact support.
Certificate Not Trusted
This usually means the certificate chain is incomplete. Your host needs to include intermediate certificates. Self-signed certificates also cause this error.
Mixed Content Warnings
Your HTTPS page is loading HTTP resources. Use your browser's DevTools to identify the offending URLs and update them in your WordPress database.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
Your server's SSL configuration doesn't match what the browser supports. This often happens with old TLS versions or weak ciphers. Your host needs to update their SSL configuration.
Frequently Asked Questions
Is SSL free with WordPress hosting?
Many WordPress hosts now include free SSL certificates, but not all. MojoShine, Cloudflare, and Let's Encrypt provide free SSL. Some budget hosts charge $50-100/year for SSL certificates. Always check if SSL is included before signing up.
What is the difference between SSL and TLS?
TLS (Transport Layer Security) is the modern, secure successor to SSL (Secure Sockets Layer). When people say "SSL certificate" today, they usually mean a TLS certificate. TLS 1.3 is the current standard, offering better security and faster performance than older versions.
Does SSL affect WordPress SEO?
Yes, SSL is a confirmed Google ranking factor. Sites with HTTPS rank higher than HTTP sites. Google Chrome also marks HTTP sites as "Not Secure," which hurts user trust and increases bounce rates. SSL is essential for WordPress SEO in 2026.
How do I know if my WordPress site has SSL?
Look for the padlock icon in your browser's address bar and check that your URL starts with https:// instead of http://. You can also use online tools like SSL Labs to test your certificate configuration and get a security grade.
Can I use a free SSL certificate for e-commerce?
Yes! Free DV certificates from Let's Encrypt provide the same encryption as expensive certificates. They're fully compliant with PCI-DSS requirements for e-commerce. The encryption strength is identical regardless of certificate price.
How often do SSL certificates need to be renewed?
Let's Encrypt certificates expire every 90 days but are renewed automatically by most hosts. Paid certificates typically last 1-2 years. Good hosting providers handle renewal automatically so you never have to think about it.
