Why do I need an SSL certificate?

SSL – technically now more accurately called TLS, though “SSL” remains the term everyone uses – is what turns “http://” into “https://” in your browser’s address bar.

Practically, it does two things. It encrypts any information passing between your website and a visitor, so a password, a form submission, or payment details can’t be intercepted in transit, and it removes the browser warning that now appears on any site without it.

That warning matters more than it might seem. Most visitors won’t know what SSL means technically, but they recognise “not secure” as a reason to leave, especially on any page asking for contact details or payment information.

Google has also confirmed HTTPS as a ranking signal – a minor one on its own, but it compounds with everything else search engines already weigh.

The practical reality is that SSL is now essentially free and automatic through most hosting providers, which means there’s very rarely a good reason not to have one.

The one place it’s worth checking specifically is renewal. Certificates aren’t permanent, and if yours isn’t set to renew automatically, it can quietly lapse, causing the exact warning it was installed to prevent in the first place.

The real question isn’t whether you need SSL. It’s whether it’s actually being monitored and renewed properly, which is exactly the kind of detail a maintenance plan should cover but often doesn’t.
