Digital Footprint
The full set of information about you that exists online, including content you control and content you don't.
A digital footprint includes everything findable about someone online: their website, LinkedIn, social profiles, press mentions, reviews, old accounts, and anything else search engines index under their name. Some of it is actively managed; much of it accumulates passively over time.
Example
A physician's digital footprint might include their practice bio, a decade-old conference listing, patient reviews on third-party sites, and a personal LinkedIn profile, all shaping the picture a new patient sees.
Nuance
A digital footprint is broader than a personal brand. A personal brand is the intentional part; the footprint includes everything, intentional or not.
