## Prompt

Explain the practical difference between HTTP and HTTPS for a website owner, and cite a source.

## Response

I'll explain the practical differences between HTTP and HTTPS from a website owner's perspective and pull a supporting source.

For a website owner, HTTP vs. HTTPS is not just letters in the URL — it's a different way of operating your site.

**1. Security and data handling**
HTTP transmits all requests and responses in plaintext that anyone monitoring the connection can read. HTTPS is HTTP with encryption and verification — it uses TLS (SSL) to encrypt requests and responses and to digitally sign them.

In practice: 
* **HTTP:** login info, passwords, credit card numbers travel as readable text.
* **HTTPS:** the same data is encrypted, meaning it is private and cannot be eavesdropped on, authenticated, and protected against tampering.

The core difference: HTTPS encrypts data between your browser and the website, while HTTP doesn't.

**2. What you need to do**

* **HTTP:** Nothing extra. Works on port 80 by default.
* **HTTPS:** You must get an SSL/TLS certificate from a Certificate Authority (CA) to set up an encrypted channel with the browser. You then need to install it, force 301 redirects from HTTP to HTTPS, and update your sitemap/search console.

**3. User trust and conversion**

Browsers show visual trust indicators. Sites using HTTPS display a padlock symbol, while HTTP sites show a warning like 'Not Secure'. Since 2018 Chrome flags all HTTP sites as "not secure," visitors bounce before engaging.

**4. SEO and compliance**

Search engines like Google prioritize secure sites over non-secure ones, meaning HTTPS sites are more likely to rank higher. HTTPS is also the easiest way to meet data-protection requirements like GDPR that require encryption of personal data in transit.

In short: HTTP is cheaper and simpler, but exposes you to interception and trust warnings. HTTPS requires a certificate and maintenance, but gives you encryption, authentication, better rankings, and browser trust.
