# What is HTTPS?

> HTTPS is the secure version of the web's connection method, encrypting information between a visitor's browser and your website so it cannot be read in transit.

Also called: HTTP Secure, secure connection, padlock.

Web addresses start with either http:// or https://. The S stands for secure: the connection is encrypted, so anyone snooping on a café Wi-Fi network cannot read what is being sent, such as form details.

HTTPS needs an SSL certificate. Browsers show a padlock or similar icon for secure sites and warn visitors about insecure ones, particularly on pages with forms.

Google has used HTTPS as a small ranking signal since 2014. More importantly, it is now simply expected: a site without it looks neglected.

## Why it matters for a small business

Customers type their name, phone number and address into your quote form. HTTPS protects that information and avoids a browser warning that makes your business look careless or untrustworthy.

**Example:** Typing http://smithplumbing.co.uk should automatically redirect to https://smithplumbing.co.uk. If it does not, the site is not set up properly.
