HTTPS
HyperText Transfer Protocol Secure
In one line
HTTPS (HyperText Transfer Protocol Secure) is HTTP traffic encrypted with TLS — and a baseline ranking signal Google has confirmed publicly.
Going deeper
HTTPS is HTTP encrypted with TLS. Google confirmed it as a lightweight ranking signal back in 2014, and at this point it's effectively a hygiene requirement rather than a competitive edge.
The operational checklist is short. Every URL on the domain should serve HTTPS, plain HTTP should 301 to its HTTPS counterpart, and the certificate plus all sub-resources have to be clean — no expired certs, no mixed content.
It is not a direct GEO citation signal, but it sets a trust baseline. When an AI weighs source credibility, a non-HTTPS domain tends to start at a disadvantage before any of the content is even read.
