Every website needs HTTPS now, not just online stores. Browsers flag any page without it as “Not Secure,” search engines weigh it as a ranking signal, and visitors have learned to bounce the moment they see that warning. The good news is that setting it up correctly takes minutes, not a specialist. Here is what SSL/TLS actually does and how to get it right.
What SSL/TLS actually does
SSL (now really TLS, though the old name stuck) encrypts the connection between a visitor’s browser and your server. Without it, anything typed into a form on your site, including passwords and payment details, travels in plain text that anyone on the same network can read. A valid certificate also proves to the browser that your site is who it claims to be, which is why the padlock icon appears next to your domain.
Encryption and identity verification are two different jobs, and a certificate does both. That is the whole point of the technology, and it is why “install SSL” really means “get a certificate and configure your server to use it.”
Why HTTPS is no longer optional
Three things changed the calculation. First, Chrome, Firefox, and every major browser now show an explicit warning on plain HTTP pages, which scares off visitors before they read a word of your content. Second, Google has confirmed HTTPS as a ranking factor, so an unsecured site is working against itself in search results. Third, any page collecting a login, an email address, or a payment is a basic trust test, and failing it costs conversions. If you are working on rankings more broadly, our SEO basics guide covers where HTTPS fits alongside other fundamentals.
Free certificates with cPanel hosting
You do not need to buy a certificate. Let’s Encrypt, a nonprofit certificate authority, issues free certificates that are trusted by every major browser, and cPanel hosting includes automatic Let’s Encrypt integration through AutoSSL. When your domain is pointed at your hosting account, AutoSSL detects it and issues a certificate without you doing anything. You can read more about how the project works at letsencrypt.org.
This is included at no extra cost on every plan we run, from OneDollar hosting up through shared hosting and unlimited hosting. There is no separate SSL product to buy and no renewal invoice to remember, because renewal is automatic too.
Installing and forcing HTTPS
In cPanel, check SSL/TLS Status to confirm AutoSSL has issued a certificate for your domain. If it has not run yet, you can trigger it manually from that screen. Once the certificate is active, the second step matters just as much: forcing every visitor onto HTTPS, not just making it available.
On most setups this means adding a redirect rule in your site’s .htaccess file so that any request to the http:// version of your domain is sent to https:// automatically. If you run WordPress, the same result is achieved by setting your Site Address to https:// under Settings, and our essential WordPress settings guide walks through that along with the other settings worth checking on a new install.
Fixing mixed-content warnings
Mixed content is the most common problem after switching to HTTPS. It happens when your page loads over a secure connection but pulls in an image, script, or stylesheet that is still hardcoded to an http:// address. Browsers block or flag those resources, which can break page styling or show a “not fully secure” warning even though your certificate is fine.
The fix is usually a straightforward search-and-replace across your database or theme files, swapping http:// for https:// in stored URLs. WordPress users can run this with a plugin or a WP-CLI search-replace command. Check your browser’s developer console after the switch; it will list exactly which resources are still loading insecurely, so you are not guessing. Google’s own developer documentation has a solid technical breakdown of the issue at developers.google.com.
Renewal and ongoing maintenance
Let’s Encrypt certificates are valid for 90 days, which is short by design, so the whole system assumes automation rather than manual renewal. On cPanel hosting, AutoSSL checks and renews certificates in the background well before expiry, so there is nothing to schedule yourself. The only time you would see a lapsed certificate is if your domain’s DNS stopped pointing at your hosting account, which is worth understanding if you are not sure how that connection works; our DNS records explained guide covers it. If you are migrating a site to new hosting, reissue and verify the certificate as one of the first steps.
Frequently asked questions
Does every plan include a free SSL certificate?
Yes. AutoSSL with Let’s Encrypt is included on all our hosting plans at no extra charge, and it renews automatically.
Will HTTPS make my site load slower?
No, the overhead from modern TLS is negligible. If your site feels slow, the cause is almost always something else, like unoptimized images or server resources; see our website speed guide for where to look.
What is the difference between SSL and TLS?
SSL is the older protocol name; TLS is its modern, more secure successor. “SSL certificate” stuck as the common term, but every certificate issued today actually uses TLS.
Can I still use HTTPS if I bought my domain elsewhere?
Yes, as long as your domain points to your hosting account’s nameservers or A record. AutoSSL works the same way regardless of where you registered the domain.
What if AutoSSL fails to issue a certificate?
This is usually a DNS propagation issue or a firewall blocking the verification request. Confirm your domain resolves correctly to your hosting IP, then retry AutoSSL from cPanel; our support team can also check it for you.
Every UWeb Solutions hosting plan includes free, auto-renewing SSL, and you can try it with a 3-day free trial on Shared hosting.
