What HTTP actually is
HTTP stands for HyperText Transfer Protocol. It's the language your browser uses to communicate with web servers — the set of rules that governs how data is requested and sent across the internet.
When you visit a website, your browser sends an HTTP request to the server saying "give me this page." The server sends back an HTTP response with the page content. This has been the foundation of the web since it was invented in 1989.
The problem is that HTTP sends everything in plain text. No scrambling, no protection, no lock on the door. Anyone who can intercept the traffic between your browser and the server can read it — exactly as it was sent.
HTTP is like sending a postcard. The message is written in the open, and every person who handles it between you and the recipient — postal workers, sorting centres, anyone — can read exactly what it says. HTTPS puts that postcard inside a sealed, tamper-proof envelope that only the recipient can open.
What HTTPS adds
HTTPS is simply HTTP with security added on top. The S stands for Secure, and what makes it secure is TLS — Transport Layer Security — which encrypts every piece of data sent between your browser and the server.
With HTTPS active, even if someone intercepts your traffic, all they see is scrambled, unreadable data. The content of the page, any forms you fill in, login credentials, personal details — all of it is protected.
HTTP
- Data sent as plain text
- Anyone can intercept and read it
- No identity verification
- Browser shows "Not secure"
- Google penalises in rankings
- Visitors leave immediately
HTTPS
- All data fully encrypted
- Intercepted data is unreadable
- Server identity verified
- Browser shows padlock
- Google ranks it higher
- Visitors trust the site
Why this matters for your business
If your website is still on HTTP in 2026, several things are actively working against you.
Google flags your site. Chrome — used by more than 65% of web users globally — shows a "Not secure" warning in the address bar for any HTTP site. This appears before a visitor even reads a single word of your content. The message it sends is clear: this site is not maintained and cannot be trusted.
Google ranks you lower. HTTPS has been a confirmed Google ranking signal since 2014. Two otherwise identical websites will rank differently in search results — the one with HTTPS will outrank the one without. For a business relying on Google to bring in clients, this is a direct commercial impact.
Form submissions are exposed. If you have a contact form on an HTTP site, everything a visitor types — their name, email, phone number, message — is transmitted in plain text. Any attacker with access to that network traffic can read it. This is particularly serious if your clients share sensitive business information through your contact form.
Public Wi-Fi networks — coffee shops, airports, hotels — are a common target for traffic interception. A potential client filling in your contact form on hotel Wi-Fi is sending their details completely exposed if your site uses HTTP. HTTPS eliminates this risk entirely.
How you get HTTPS
To enable HTTPS, your website needs a TLS certificate — a digital ID that proves your server is who it claims to be and enables the encryption. This is what the padlock in your browser actually represents.
TLS certificates used to cost money and require manual installation and annual renewal. That changed significantly around 2016 when a non-profit called Let's Encrypt began issuing free, automatic certificates. Today, every major hosting platform — Cloudflare, Netlify, and others — issues and renews TLS certificates automatically for every site they host.
In practice, this means that if you build and host your website through a modern platform, HTTPS is simply on by default. You don't pay for it, you don't manage it, and you don't have to think about it renewing. It just works.
Every website we build and host comes with HTTPS active from day one. TLS certificates are provisioned automatically and renew automatically — it's never an extra cost and never something you need to chase up.
How to check your own site right now
Open your website in a browser. Look at the address bar. If you see a padlock icon and the address starts with https://, you're protected. If you see "Not secure" or the address starts with just http://, your site needs attention.
If your site is on HTTP and you're not sure how to fix it, the answer depends on your hosting setup. Some older hosting providers require you to manually request and install a certificate. Others have a simple toggle in their settings. Moving to a modern hosting platform like Cloudflare Pages typically solves it automatically as part of the migration.
Type your website address into your browser right now. If you don't see a padlock, contact your hosting provider and ask specifically: "How do I enable HTTPS and get an SSL certificate for my site?" Most providers can walk you through it in minutes.
Key takeaways
- HTTP sends data as plain text — anyone intercepting the traffic can read it
- HTTPS encrypts all data between your browser and the server
- The encryption in HTTPS is provided by TLS (often still called SSL)
- Google flags HTTP sites as "Not secure" and ranks them lower in search results
- Contact form submissions on HTTP sites are transmitted in plain text — a real security risk
- TLS certificates are now free and automatic on all modern hosting platforms
- If your site doesn't have the padlock, fix it — it's usually quick and costs nothing
What's next
Now that you understand what HTTPS is and why it matters, the natural next question is: how exactly does the encryption work? That's covered in the TLS article — it goes deeper into the handshake process and how the padlock actually gets there.
And if you're wondering how your browser even finds the right server in the first place before any of this encryption happens, that's DNS — covered in the networking article below.
