## Prompt

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

## Response

HTTPS is a security upgrade to HTTP that encrypts all traffic between a website and visitors, preventing eavesdropping, tampering, and injected content, while HTTP sends data in plain text, exposing it to interception and modification by third parties  [letsencrypt.org](https://letsencrypt.org/docs/why-all-https/) [aws.amazon.com](https://aws.amazon.com/compare/the-difference-between-https-and-http/) [cloudflare.com](https://www.cloudflare.com/learning/ssl/why-use-https/).

Practical implications for site owners
- **Privacy and integrity**: HTTPS prevents ISPs, Wi‑Fi operators, or attackers from reading or altering content in transit.
- **Malware injection blocked**: Without HTTPS, intermediaries can inject ads, tracking scripts, or malware into pages without consent.
- **Regulatory compliance**: Many privacy laws (e.g., GDPR) require encryption for processing personal data; HTTPS helps fulfill these obligations.
- **SEO and trust**: Major search engines rank HTTPS pages higher, and browsers label HTTP sites as “Not secure,” hurting user trust and conversions.
- **Referrer accuracy**: HTTPS preserves the full referrer URL in analytics; with HTTP, referrer information is often stripped or lost.
- **Modern browser features**: Many APIs (geolocation, camera, payments) require a secure context, so HTTPS is a prerequisite for features that drive engagement and revenue.

In short, migrating from HTTP to HTTPS addresses security risks, legal exposure, SEO penalties, and feature limitations that directly impact a site’s performance and reputation.
