The secure version of the HTTP protocol. Google prefers encrypted websites.
What is HTTPS?
HTTPS (Hypertext Transfer Protocol Secure) is the encrypted version of the HTTP protocol. It protects data sent between browser and server with SSL/TLS encryption.
Example: a visitor fills in the contact form of a law firm. If the site runs on HTTPS, the name and message are encrypted on their way to the server and the browser shows a secure connection. On plain HTTP, the same page is marked "Not secure".
HTTPS as a ranking factor
Google confirmed HTTPS as an official ranking factor in 2014. Chrome marks websites without HTTPS as "Not secure", which seriously damages user trust.
- Data protection – encrypts sensitive user data
- Trust signal – part of the E-E-A-T assessment (Trustworthiness)
- Ranking boost – a small but measurable SEO advantage
Because trustworthiness is part of E-E-A-T, HTTPS also supports how search engines and AI systems judge a source. A correct HTTPS setup belongs to technical SEO, and our technical SEO checklist covers it.
