## Prompt

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

## Response

**HTTPS encrypts traffic and improves trust, security, and search rankings compared to plain HTTP.**

## Security and Data Protection
HTTPS uses TLS/SSL to encrypt data exchanged between the browser and server, preventing interception of sensitive information like login credentials or payment details.  
HTTP transmits data in plain text, exposing it to eavesdropping or man-in-the-middle attacks on public networks.

## Browser and User Experience
Modern browsers display "Not Secure" warnings for HTTP sites, which can reduce visitor trust and increase bounce rates.  
HTTPS sites show a padlock icon, signaling safety and avoiding these warnings.

## SEO and Search Rankings
Google treats HTTPS as a lightweight ranking signal, giving secure sites a slight advantage in search results.  
HTTPS also preserves referrer data in analytics, supporting better measurement of traffic sources.[[1]](https://developers.google.com/search/blog/2014/08/https-as-ranking-signal)

## Practical Requirements for Owners
Website owners must obtain and install an SSL/TLS certificate (free options like Let's Encrypt exist), configure server redirects from HTTP to HTTPS, and enable HTTP Strict Transport Security (HSTS) for full protection.  
Certain features, such as payment processing, require HTTPS for regulatory compliance.
