Aaron’s brand doesn’t have a standard font yet. Which font does LinkedIn NOT recommend he explore for his ads?

LinkedIn recommends using professional, legible fonts that enhance brand credibility. Helvetica, Open Sans, and Sans Serif are all widely accepted, clean, and modern font families suitable for professional advertising. Comic Sans, however, is generally considered unprofessional and informal, often associated with childish or amateurish designs. Its playful, handwritten style can detract from a brand's authority and is therefore not recommended for business advertising on platforms like LinkedIn.
