TARP stands for Target Audience Rating Point and it refers to the proportion of an advertisers target audience that is exposed to a campaign or programme.
TARPs are typically used for TV advertising that is brought against a specific demographic or audience segment.
TARP = Average audience viewing a programme / target universe estimate x 100
‘Universe estimates’ estimate the total audience size. For example, in 2019, the universe estimate for Melbourne metro is 5,243,200.
So let’s say 720,000 women aged 25-to-39 were exposed to an advertising campaign from a total universe of 4,800,000 people, then the campaign delivers a TARP of 15 since 720,000 divided by 4,800,000 equals 15.
