## Prompt

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

## Response

I'll pull current sources to lay out the practical differences between HTTP and HTTPS and cite them for you.

For a website owner, the difference between HTTP and HTTPS is not just the letter S — it's how your site handles security, trust, and visibility.

**Security and data privacy**
HTTPS is HTTP with encryption and verification. The only difference between the two protocols is that HTTPS uses TLS (SSL) to encrypt normal HTTP requests and responses [Cloudflare](https://www.cloudflare.com/learning/ssl/why-is-http-not-secure/).

With HTTP, websites transmit data in the clear, which means that an adversary could wiretap the connection [Similarweb](https://www.similarweb.com/blog/marketing/seo/http-vs-https/). An HTTPS website uses SSL/TLS to encrypt the data, meaning that it is private and cannot be eavesdropped on [Similarweb](https://www.similarweb.com/blog/marketing/seo/http-vs-https/). That also protects it against tampering and man-in-the-middle attacks.

In practical terms, if you collect passwords, contact forms, or payment details over HTTP, anyone monitoring the connection can read them in plaintext.

**What you need to run it**
To run HTTPS at all, a site needs to get an SSL/TLS certificate from a Certificate Authority (CA), so that it can set up an encrypted channel directly with the browser [Similarweb](https://www.similarweb.com/blog/marketing/seo/http-vs-https/). For HTTP, no certificate is needed.

**User trust in the browser**
Sites using HTTPS display a padlock icon. This indicates a secure connection [Semrush](https://www.semrush.com/blog/http-vs-https/). HTTP sites show a “Not Secure” warning instead, which stops many visitors from proceeding.

**SEO and compliance**
Using HTTPS can significantly boost your website’s visibility in search engines. Search engines like Google prioritize secure sites over non-secure ones [Similarweb](https://www.similarweb.com/blog/marketing/seo/http-vs-https/). Google treats HTTPS as a positive ranking signal [Semrush](https://www.semrush.com/blog/http-vs-https/).

It is also now a baseline for legal compliance. Data protection regulations like GDPR require appropriate technical measures to protect user data during transmission, and HTTPS is the easiest way to meet that.

**Features and performance**
Most modern browser features — payment processing, geolocation, push notifications, progressive web apps — require HTTPS. Early HTTPS was slower, but with HTTP/2, it is now almost as fast as HTTP.

For a website owner today, staying on HTTP means: data at risk, browser warnings, lower trust, and a disadvantage in search. Switching to HTTPS means installing and maintaining an SSL certificate, forcing a 301 redirect to https://, and updating your sitemap.
