Personifi Knows the Difference
Personifi ensures that your ads get placed in a safe, risk-free environment because it “reads” pages based on the context of the page, not just keywords. An advertiser running ads for airplanes can rest assured that Personifi won’t serve ads to pages about insects or zippers.

Context NOT Keywords
Personifi “reads” pages based on the context of the page, not just keywords.
¿Habla usted Personifi®?
Personifi analyzes pages based on context in multiple languages, not just keywords, ensuring a more accurate placement.
