There are four main types of user personas. The four types are:
User personas: Also known as design personas. These are personas that aid UX and UI design processes and product-build decisions.
Marketing personas: Also known as buyer personas. A buyer persona helps product marketing teams go to market.
Proto-personas: These are rapid personas built on gut instinct and common user knowledge a business has. They’re often relied on when you don’t have the time for anything more in-depth.
Persona spectrums: A much more inclusive approach to building user personas, spectrums accumulate research data but form a wider array of personas, rather than building one specifically—which could limit its usability.
