Googleganger is a fairly new word; it has an equally interesting synonym in doppelgoogler.

A googleganger is a person who has the same name as you and is discovered when you search for yourself using an internet search engine.

The origin of both googleganger and doppelgoogler is the originally German word doppelgänger, meaning ‘a double of a living person’.

Googleganger has been named the Macquarie Dictionary word of the year (2010) and was nominated (in the form Googlegänger) for word of the year (2007) by the American Dialect Society.
