TL;DR: To switch from HTTP to HTTPS, install an SSL certificate (free via Let’s Encrypt on most hosts), update your WordPress site URLs to https://, replace internal HTTP references in the database, fix any mixed content, then enable a site-wide 301 redirect. On a standard WordPress site with a modern managed host, the migration takes 30 to 60 minutes, and clean migrations stabilize in search within a few weeks.
Your visitors see it before they see your homepage. The “Not Secure” label appears in the address bar on every HTTP page, and for many visitors, it’s enough to close the tab before they read a word of your content.
The fix is straightforward for most business websites, but the order of operations matters. Skipping steps or reversing the sequence can take your site offline, damage search rankings, or leave half your pages still loading insecure content after you think the work is done.
This guide covers every step of the process: SSL certificate setup, WordPress configuration, cPanel redirect rules, and post-migration SEO validation.
Why Your Browser Is Flagging Your Site as ‘Not Secure’
Browsers including Chrome and Firefox display the “Not Secure” label for any page served over HTTP, not just pages with login forms or payment fields. A contact form, a blog post, a services page: every HTTP page triggers the warning.
HTTP transmits data in plain text between a visitor’s browser and your web server. Anyone positioned to intercept that traffic can read it. For a business that collects quote requests, contact submissions, or account credentials, that’s not a theoretical concern.
The impact extends beyond visitor trust. Google confirmed HTTPS as a ranking signal in 2014 and has progressively made the “Not Secure” warning more prominent in Chrome since then. A site running on HTTP is at a ranking disadvantage, and every visitor who lands on it sees a browser flag signaling their information isn’t protected.
HTTP vs. HTTPS: What the Difference Really Means
HTTP (HyperText Transfer Protocol) is the baseline communication layer between browsers and web servers. It moves data efficiently but provides no encryption for what’s being moved.
HTTPS adds TLS (Transport Layer Security) on top of HTTP. An SSL certificate installed on the server encrypts all data in transit and authenticates the connection. This confirms that visitors are reaching your legitimate server rather than an impersonator intercepting the request. The two protocol names are often used interchangeably; SSL vs. TLS explains the difference.
For business owners, the practical advantages of HTTPS are:
- Encrypted data in transit between your visitors and your server
- Satisfied browser security requirements across Chrome, Firefox, and Edge
- Payment processor compliance support for standards that require HTTPS
- A confirmed Google ranking signal, minor in weight but real
One point to be precise about: an SSL certificate means the connection is encrypted. It does not mean the website is free of vulnerabilities or that the business behind it is trustworthy. The security conversation extends well beyond the certificate. For a fuller picture, see why HTTPS matters for secure online transactions.
What You Need Before You Migrate
A clean migration depends on preparation. Skipping any item in this checklist means discovering the problem after the switch, when reversing course is more disruptive.
- Obtain your SSL certificate. Most hosts include a free Let’s Encrypt certificate activatable directly from cPanel. Paid DV, OV, or EV certificates provide higher identity assurance and are standard for regulated industries or customer-facing portals. Either way, the certificate is issued by a certificate authority.
- Back up your site completely. Back up both your files and your database before touching any configuration. Proper data backup and recovery services make this a quick, repeatable step rather than an afterthought.
- Record your baseline. Document your current rankings in Google Search Console and traffic in Google Analytics. Any post-migration change becomes immediately visible when you have a reference point to compare against.
- Audit your existing URLs. Identify canonical tags, sitemap entries, and hardcoded internal links that reference HTTP. All of them need to be updated to their HTTPS equivalents after the switch.
- Confirm your hosting environment supports SSL. Virtually every cPanel-based host does, and most managed WordPress platforms activate HTTPS with a single toggle in the settings panel.
How to Switch Your Website from HTTP to HTTPS
With your backup confirmed and your SSL certificate obtained, the migration follows a repeatable sequence.
Running WordPress? Most small-business sites are, and the steps below are written for it. If you’re on a managed WordPress platform, check the settings panel first — many activate HTTPS with a single toggle. On a standard cPanel host, steps 1 through 5 below are the full job: certificate, site URLs, database references, mixed content, testing.
- Install the SSL certificate in cPanel. Navigate to SSL/TLS in your cPanel dashboard and activate or upload the certificate for your domain. Most hosts surface a one-click Let’s Encrypt activation from the same panel, so check for that option before attempting a manual installation.
- Update your WordPress site URLs. Go to Settings > General in your WordPress admin and change both the WordPress Address and Site Address fields from
http://tohttps://. Save the settings and confirm the site still loads before moving forward. - Replace internal HTTP references in the database. The Better Search Replace plugin handles this reliably for most WordPress installs. Run it to update all stored
http://links, image paths, and embedded asset URLs across your database tables. Developers with direct database access can achieve the same result with a SQL query targetingwp_options,wp_posts, andwp_postmeta. - Check for mixed content. Open Chrome DevTools (Console tab) and reload your key pages. Any resource still loading over HTTP, including scripts, CSS stylesheets, or images, will appear as a warning here. Resolve every warning before enabling redirects.
- Test the HTTPS version thoroughly. Confirm all pages load without console errors, all forms submit correctly, and the padlock icon appears across your main page templates. This is your checkpoint before flipping the redirect live.
Setting Up 301 Redirects and Protecting Your SEO
A 301 (permanent) redirect from HTTP to HTTPS tells search engines the move is permanent. This transfers the link equity your HTTP URLs have built over time to the new HTTPS versions, preserving your rankings rather than resetting them.
In cPanel, the Redirects tool configures a site-wide HTTP-to-HTTPS redirect without requiring manual edits to server configuration files. For Apache-based servers, the same redirect is written as a RewriteRule in your .htaccess file:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]Verify the syntax carefully before saving. A malformed rule makes the site unreachable until corrected.
After redirects are live:
- Add the HTTPS property in Google Search Console
- Submit an updated XML sitemap so Google re-crawls the new URLs promptly
- Monitor the coverage report for crawl errors over the following two to four weeks
A brief ranking fluctuation after the switch is normal. Sites with clean migrations stabilize within a few weeks, and the coverage reports surface any crawl errors quickly.
Before making any server-level changes, document a tested rollback procedure. Restoring from a clean backup is significantly faster than debugging a broken redirect chain while your site is unreachable.
What HTTPS Won’t Fix (and What to Watch For)
HTTPS encrypts data in transit. It addresses nothing else.
It doesn’t protect against:
- Malware hosted on your site
- Phishing content on your domain
- Compromised admin credentials
- Unpatched plugins with known vulnerabilities
Those vulnerabilities exist at the application layer. A green padlock says nothing about any of them.
Mixed content is the most common post-migration problem. A single image or script still loading over HTTP suppresses the padlock icon across your entire site, even when every other asset is secure. A thorough audit after the switch catches these before visitors do.
HTTPS also does nothing for data at rest. Server hardening, access controls, patch management, and regular backups are separate obligations that the SSL certificate doesn’t touch. Treating HTTPS as a complete security posture leaves your business exposed to credential-based attacks, injection vulnerabilities, and account compromise.
Let’s Encrypt certificates expire every 90 days. An expired certificate triggers browser warnings as severe as those triggered by plain HTTP. Automated renewal monitoring is the ongoing obligation the migration creates. It slips through the cracks when nobody owns it explicitly.
When to Handle This In-House vs. When to Hand It Off
For a standard WordPress site on a modern managed host with built-in SSL management, this typically takes 30 to 60 minutes. The assumption is basic admin access and no custom server configuration.
Several scenarios raise the complexity significantly:
- WordPress multisite installations, where URL changes need to propagate correctly across all subsites
- E-commerce platforms with payment gateway integrations that carry their own HTTPS requirements and configuration dependencies
- Custom-coded sites where database updates require direct server access rather than a plugin
- Sites with legacy HTTP assets embedded across hundreds of posts, where a standard search-and-replace can miss edge cases buried in theme files or third-party scripts
If your team lacks server-level access or isn’t comfortable with DNS (Domain Name System) records, Apache configuration, or direct database queries, the calculation changes. A misconfiguration typically costs more to fix than getting the migration right from the start.
What Switching to HTTPS Costs
For most business sites, the certificate itself is free. The real costs are staff time and the risk of a botched configuration:
| Cost item | Typical cost | Notes |
|---|---|---|
| Let’s Encrypt SSL certificate | Free | Included with most cPanel hosts; renews every 90 days |
| Paid DV, OV, or EV certificate | — | Higher identity assurance; standard for regulated industries and customer-facing portals |
| DIY migration, standard WordPress site | 30–60 minutes of staff time | Assumes basic admin access, a modern managed host, and no custom server configuration |
| Complex migration (multisite, e-commerce, custom-coded) | — | Scope grows with payment gateway dependencies, direct database work, and legacy HTTP assets |
| Managed migration | Bundled into ongoing site management | Covers SSL provisioning, auto-renewal, redirects, mixed-content auditing, and monitoring |
Managed website services handle SSL provisioning, certificate auto-renewal, redirect configuration, mixed-content auditing, and ongoing monitoring as part of regular site management. The migration becomes one handled item in an ongoing workflow rather than a one-time project with a long tail of follow-up tasks that rarely get completed on schedule.
Frequently Asked Questions
How do I convert HTTP to HTTPS?
Install an SSL certificate on your server (most cPanel hosts include a free Let’s Encrypt option), update your WordPress Address and Site Address fields to https://, replace internal HTTP references in the database, and resolve any mixed-content warnings. Then enable a site-wide 301 redirect. Test forms and key pages at each step. On a standard WordPress site, the full sequence takes 30 to 60 minutes.
Can you redirect HTTP to HTTPS?
Yes. A 301 (permanent) redirect sends all HTTP traffic to the HTTPS versions of your pages and tells search engines the move is permanent, transferring the link equity your old URLs have built. Configure it through cPanel’s Redirects tool, or with a RewriteRule in your .htaccess file on Apache servers. Enable the redirect only after the HTTPS version of your site tests clean.
How to enable HTTPS from HTTP?
Start with the certificate: open SSL/TLS in your cPanel dashboard and activate or upload a certificate for your domain — most hosts offer one-click Let’s Encrypt activation. Many managed WordPress platforms enable HTTPS with a single toggle in the settings panel. Once the certificate is live, update your site URLs and set the 301 redirect so every visitor lands on the secure version.
What are the advantages of HTTPS instead of HTTP?
HTTPS encrypts data in transit between your visitors and your server, satisfies browser security requirements in Chrome, Firefox, and Edge, supports payment processor compliance standards, and is a confirmed Google ranking signal — minor in weight, but real. It also removes the “Not Secure” label that pushes visitors away before they read a word of your content.
What are the disadvantages of HTTPS?
There is no practical downside to HTTPS itself; the disadvantage is maintenance. Let’s Encrypt certificates expire every 90 days, and an expired certificate triggers browser warnings as severe as plain HTTP. The migration also creates one-time work — mixed-content cleanup, redirect configuration, and a brief ranking fluctuation while Google re-crawls. None of that argues for staying on HTTP.
Where to Go from Here
If your site is still running on HTTP, the migration is overdue. The steps above are repeatable for most WordPress-based business sites, and the trust and ranking benefits take effect as soon as the redirects go live. The longer the delay, the more visitors encounter that “Not Secure” label and move on.
The one-time migration is manageable for most teams. The ongoing work is where businesses consistently fall behind:
- Certificate renewals before browsers flag an expired SSL
- Mixed-content monitoring as new assets are added to the site
- Redirect integrity as URLs change and the site evolves
That’s the work that accumulates between projects until something breaks.
To move from reactive fixes to managed ongoing maintenance, see what managed website services include.
When SSL certificate maintenance, redirect configuration, and ongoing website security become managed responsibilities rather than recurring emergencies, your team can focus on the work that actually moves the business forward.
