Reach and Frequency are two different factors used to evaluate the effectiveness of your outdoor media program in exposing your Target Audience to your advertising message during your AdVision campaign.

Reach:

Reach is the percentage of a Target Audience exposed (given an opportunity to see) to your outdoor advertising message at least one time. Reach (unduplicated Audience) is normally calculated for a schedule of locations over a specified period of time (1 to 4 weeks).

Frequency:

Frequency is the average number of times that an individual in your Target Audience has the opportunity to see your advertising message during a specified period of time.

An outdoor media Reach estimate should reflect Audience accumulation over time in the same way that a broadcast or print Reach estimate reflects Audience accumulation.

The Reach and Frequency calculations provided above were derived using the Gallop Math Model method.

The Gallop Math Model is an industry accepted arithmetic formula that has been in use for over 40 years. For more information on the Gallop Math Model, please see the Glossary provided in this website.
