If your website still shows "Not Secure" in the browser address bar, you are losing visitors before they even read your content. SSL certificates are no longer optional — they are a baseline requirement for trust, search ranking, and increasingly for browser compatibility.
The good news: for most small business websites, a proper SSL certificate costs nothing. Here is everything you need to know.
What Is SSL and Why Does It Matter?
SSL (Secure Sockets Layer) — now technically TLS — encrypts data transmitted between your website and your visitors. Without it, data like form submissions, login credentials, and payment details travel in plain text that can be intercepted. With it, the data is encrypted end-to-end.
Practically, SSL matters because:
- Google ranks HTTPS sites higher — it has been a ranking factor since 2014
- Chrome and Firefox mark HTTP sites as "Not Secure" — visible to every visitor in the address bar
- Many browsers block form submissions on non-HTTPS pages
- Payment processors require HTTPS — you cannot accept card payments without it
Types of SSL Certificates
| Type | Validates | Cost | Best For |
|---|---|---|---|
| DV (Domain Validated) | Domain ownership only | Free–£80/yr | Small business websites, blogs |
| OV (Organisation Validated) | Domain + business identity | £50–300/yr | Company sites, professional services |
| EV (Extended Validation) | Full legal business verification | £100–500/yr | Financial institutions, enterprise |
| Wildcard | Domain + all subdomains | £70–400/yr | Sites with multiple subdomains |
| Multi-domain (SAN) | Multiple different domains | £100–500/yr | Agencies, businesses with multiple sites |
What Most Small Businesses Actually Need
A standard DV certificate from Let's Encrypt is sufficient for the vast majority of small business websites. It provides the same encryption as certificates costing £300/year — the only difference is that it does not display your company name in the certificate details. For a 5-page business website or a WordPress site, Let's Encrypt is the right choice.
How to Install a Free SSL Certificate
On cPanel Hosting
- Log into cPanel → Security → SSL/TLS → Manage SSL Sites
- Or look for "AutoSSL" in cPanel — most cPanel hosts include automatic Let's Encrypt SSL
- If AutoSSL is not available, go to cPanel → Let's Encrypt (or ask your host to enable it)
On aaPanel (VPS)
- Go to Website → your domain → SSL
- Select Let's Encrypt → Apply
- Enable "Force HTTPS" once the certificate is installed
After Installing SSL
- Force HTTPS: add a redirect in your .htaccess or Nginx config so all HTTP traffic redirects to HTTPS
- Update WordPress site URL: in Settings → General, change both URLs from http:// to https://
- Run a mixed content check: use WhyNoPadlock.com to find any resources (images, scripts) still loading over HTTP
- Update your Google Search Console property to the HTTPS version
- Set up auto-renewal: Let's Encrypt certificates expire every 90 days — ensure auto-renewal is configured
