7.2. Media Planning II Flashcards
Evaluating media effectiveness - reach
- percentage of target audience that is exposed to an advertisement at least once during a certain time frame (usually 4 weeks)
factors determining reach
- more people are reached when a media schedule uses multiple media
- number and diversity of media vehicles used
- diversifying the day parts
the (in)sufficiency of relying on reach
- in terms of CPM model, reach indicates only the number of people exposed to an ad
- in terms of hierarchy of effects model, reach doesn’t really guarantee that consumers will even be aware of the brand
Evaluating media effectiveness -frequency
average no of times an advertisement is exposed to the target audience in a four-week period
Evaluating media effectiveness - weight (=impact)
Gross rating points (GRPs) are an indicator of the amount of gross weight that a particular ad schedule is capable of => reflects overall impact of the ad schedule
GRPs Formula
Reach x Frequency
Ratings x # of Buys
GRPs are sum of all…
vehicle ratings in a media schedule
Rating
proportion of the target audience presumed to be exposed to a single occurrence of an ad vehicle in which the advertisers brand is advertised
Why does deciding on level of reach and frequency involve tradeoffs

CPM
Cost per Mile
CPT
Cost per thousand
lower CPM means…
higher efficiency
CPM/ CPT across media
not comparable
CPM based on circulation for print media - formula
(unit cost/ circulation) x 1000
CPM based on rating for print media - formula
(Unit cost/ rating x # of target audience) x 1000
