Why Your Website Needs an SSL Certificate — and When a Free One Is Enough

If your website is open to the public, visitors now expect a secure connection. Without it, browsers can warn them — or, in Google Chrome, ask for permission before the page even opens. An SSL certificate is what makes that secure connection possible. This note explains what it does, why it matters for trust and search visibility, and how to choose between a free certificate and a paid one.

What an SSL certificate is for

Think of an SSL certificate as a small digital ID for your website.

When a visitor opens your site, their browser checks this ID, then opens a private connection. The address starts with https (the “s” means secure), and a padlock appears in the address bar. Information sent through the page — a contact form, a login, or a payment — is encrypted, so it is much harder for anyone in between to read or change it.

You may also hear the word HTTPS. It is simply the secure version of a web address. The certificate is what allows HTTPS to work.

You do not need to understand the technology behind it. What matters is this: the certificate tells the visitor’s browser, “this is the right website, and this connection is private.”

Why every website should have one

This is no longer only for online shops. It applies to company sites, service pages, and simple enquiry forms as well.

Browsers will warn visitors — or stop them first

For years, Chrome, Edge, Safari, and Firefox have labelled sites without a secure connection as “Not Secure.” That warning appears before a customer has read a word of your content, and it can look as if the business itself is unsafe.

Google has now gone further. In an official Chrome blog post on 21 October 2026, Google said Chrome now asks users for permission before connecting to a public website that is not using HTTPS. The older “Not Secure” label only appeared after the page had already loaded. The new prompt appears first. A visitor who is in a hurry may simply leave.

Google Search prefers a secure site

In 2014, Google announced that it uses HTTPS as a signal in search ranking. It described the signal as a lightweight one — still less important than high-quality content — but the direction has been consistent ever since: Google wants websites to use a secure connection. In Google Search Console, Google also says it strongly recommends HTTPS, and that if a page exists on both a regular and a secure address, Google prefers to index the secure version.

In short: a missing certificate can cost you trust in the browser, and it can put you at a disadvantage in search. A valid certificate will not, by itself, put you at the top of Google. It does remove a clear reason for visitors — and for Google — to treat the site as incomplete.

Free SSL certificates

A free certificate is enough for most business websites. It still encrypts the connection, still shows https and the padlock, and still satisfies what browsers and Google expect for a public site.

Three widely used free options are:

Let’s Encrypt. A nonprofit whose mission is to make secure websites available to everyone. The certificates are free. Many hosting companies install and renew them automatically, so the site stays secure without anyone on your team managing dates.

Google Trust Services (GTS). Google’s own certificate service. It issues trusted certificates for Google’s services, and Google also offers publicly trusted certificates at no charge. For many organisations, the appeal is simply that the issuer is Google.

Cloudflare. If a domain is set up on Cloudflare, Cloudflare issues and renews a free Universal SSL certificate by default. For a typical company website — the main domain and common addresses such as www — this is handled in the background.

A free certificate usually confirms that you control the domain name. It does not, by itself, prove the legal identity of the company behind the site. For most company websites and enquiry forms, that is enough.

When a paid certificate is worth considering

A paid certificate does not make the padlock “more locked.” A correctly set-up free certificate already encrypts the connection. What you pay for is mainly extra verification, broader coverage, and commercial support.

Paid certificates are typically offered in three levels:

• Domain validation (DV) — confirms you control the website address. This is the same type of check used by Let’s Encrypt, Google Trust Services, and Cloudflare’s free certificate.
• Organisation validation (OV) — the issuer also checks that a real organisation is behind the site.
• Extended validation (EV) — a more thorough check of the organisation. This can matter when a partner, a customer, or an internal policy asks for a named commercial certificate tied to the company.

Other practical reasons to choose a paid certificate:

• You want one certificate that covers all subdomains (often called a wildcard) or several websites, purchased and supported through a vendor.
• You want a named commercial brand — for example RapidSSL or GoDaddy — and a support desk if the certificate needs to be reissued.
• Some paid certificates include a warranty from the issuer.

For most small and mid-size company websites, a free certificate is the sensible default. A paid organisation or extended validation certificate is worth discussing if the site takes payments, handles sensitive information, or needs to show that the business itself has been checked — not only the domain name.

You do not have to set this up yourself

An SSL certificate can be arranged when you register a domain or set up website hosting. In that case, you do not need to install or configure anything on your own. Renewal can also be handled with the hosting, so the certificate does not quietly expire.

If you already have a website and are not sure whether it has a valid certificate — or whether a free or paid option is the better fit — we can check the site and arrange the certificate with your domain or hosting.
