If you visit a website and your browser shows “Not Secure” in the address bar, what do you do? Most people leave immediately. That warning appears when a website doesn’t have an SSL certificate — and if your site is one of them, it’s costing you visitors every single day.
What is SSL?
SSL (Secure Sockets Layer) is a technology that encrypts the connection between a visitor’s browser and your website. When SSL is active, your website address starts with “https://” instead of “http://”, and browsers display a padlock icon to show the connection is secure.
In practical terms, it means that any information exchanged between the visitor and your website — contact form submissions, login details, payment information — is encrypted and can’t be intercepted by third parties.
Why every website needs it
Browser warnings scare visitors away
Chrome, Safari, Firefox, and Edge all display prominent warnings on sites without SSL. Chrome marks them as “Not Secure” right in the address bar. For a business trying to build trust with potential customers, that’s devastating.
Google uses it as a ranking factor
Google confirmed years ago that HTTPS is a ranking signal. All else being equal, a secure site will outrank an insecure one. It’s a small factor, but in competitive local markets like Cambridge, every advantage counts.
It protects your visitors
Even if your website doesn’t process payments, it almost certainly has a contact form. Without SSL, the information your visitors submit — their name, email, phone number — is sent in plain text across the internet. SSL encrypts that data in transit.
It’s required for modern web features
Many modern browser features simply don’t work without HTTPS. Geolocation, service workers, and some payment APIs all require a secure connection.
Common misconceptions
“I don’t sell anything online, so I don’t need SSL.” You need SSL regardless. Browser warnings alone make it essential, even for a simple brochure website.
“SSL certificates are expensive.” Not anymore. Let’s Encrypt provides free SSL certificates, and most quality hosting providers include SSL at no extra cost. There’s genuinely no reason not to have one.
“Installing SSL will break my website.” It can cause issues if not done properly — mixed content warnings, redirect loops, and broken images are common when SSL is added as an afterthought. But when set up correctly from the start, it’s seamless.
What we do
Every website we build at Red Web Cambridge includes SSL from day one. Our managed hosting includes automatic SSL certificate provisioning and renewal, so you never need to think about it. If you have an existing site without SSL, we can add it and ensure everything works correctly.
It’s one of those things that should just be handled — and with us, it is.
