METHODS AND APPARATUS TO DETERMINE AUDIENCE ENGAGEMENT INDICES ASSOCIATED WITH MEDIA PRESENTATIONS
Methods, apparatus, and articles of manufacture to determine audience engagement indices associated with media presentations are disclosed. An example method involves determining a first engagement index associated with media based on a quantity of users of an Internet service that have posted messages containing a keyword associated with the media between a first time and a second time. The example method also involves weighting the first engagement index with a first weight. The example method also involves determining a second engagement index based on a survey of panel members exposed to the media at the first time. The example method also involves weighting the second engagement index with a second weight, and determining a composite engagement index based on the weighted first engagement index and the weighted second engagement index.
1 . A method, comprising:
determining, via a processor, a first engagement index associated with media based on a quantity of users of an Internet service that have posted messages containing a keyword associated with the media between a first time and a second time;
weighting the first engagement index with a first weight;
determining a second engagement index based on a survey of panel members exposed to the media at the first time;
weighting the second engagement index with a second weight; and
determining a composite engagement index based on the weighted first engagement index and the weighted second engagement index.
2 . A method as defined in claim 1 , wherein the first engagement index associated with the media is based on ones of the quantity of the users of the Internet service that are unique.
3 . A method as defined in claim 1 , wherein the first weight is proportional to a total number of users registered with the Internet service.
4 . A method as defined in claim 3 , wherein the total number of users registered with the Internet service is determined using the users registered with the Internet service that are unique.
5 . A method as defined in claim 1 , wherein the second weight is proportional to a total number of the panel members used to determine the second engagement index.
6 . A method as defined in claim 1 , wherein the first and second weights are based on a total number of users in a targeted group registered with the Internet service and a total number of panel members in the targeted group used to determine the second engagement index.
7 . A method as defined in claim 6 , wherein the targeted group is based on demographics of members of the targeted group.
8 . An apparatus, comprising:
an Internet engagement index generator to determine a first engagement index associated with media based on a quantity of users of an Internet service that have posted messages containing a keyword associated with the media between a first time and a second time;
a survey engagement index interface to determine a second engagement index based on a survey of panel members exposed to the media at the first time; and
a total engagement index generator to:
apply a first weight to the first engagement index;
apply a second weight to the second engagement index; and
determine a composite engagement index based on the weighted first engagement index and the weighted second engagement index.
9 . An apparatus as defined in claim 8 , wherein the first engagement index associated with the media is based on ones of the quantity of the users of the Internet service that are unique.
10 . An apparatus as defined in claim 8 , wherein the first weight is proportional to a total number of users registered with the Internet service.
11 . An apparatus as defined in claim 10 , wherein the total number of users registered with the Internet service is determined using the users registered with the Internet service that are unique.
12 . An apparatus as defined in claim 8 , wherein the second weight is proportional to a total number of the panel members used to determine the second engagement index.
13 . An apparatus as defined in claim 8 , wherein the first and second weights are based on a total number of users in a targeted group registered with the Internet service and a total number of panel members in the targeted group used to determine the second engagement index.
14 . An apparatus as defined in claim 13 , wherein the targeted group is based on demographics of members of the targeted group.
15 . A tangible machine readable storage medium comprising machine readable instructions that, when executed, cause a machine to at least:
determine a first engagement index associated with media based on a quantity of users of an Internet service that have posted messages containing a keyword associated with the media between a first time and a second time;
weigh the first engagement index with a first weight;
determine a second engagement index based on a survey of panel members exposed to the media at the first time;
weigh the second engagement index with a second weight; and
determine a composite engagement index based on the weighted first engagement index and the weighted second engagement index.
16 . A tangible machine readable storage medium as defined in claim 15 , wherein the first engagement index associated with the media is based on ones of the quantity of the users of the Internet service that are unique.
17 . A tangible machine readable storage medium as defined in claim 15 , wherein the first weight is proportional to a total number of users registered with the Internet service.
18 . A tangible machine readable storage medium as defined in claim 17 , wherein the total number of users registered with the Internet service is determined using the users registered with the Internet service that are unique.
19 . A tangible machine readable storage medium as defined in claim 15 , wherein the first and second weights are based on a total number of users in a targeted group registered with the Internet service and a total number of panel members in the targeted group used to determine the second engagement index.
20 . A tangible machine readable storage medium as defined in claim 19 , wherein the targeted group is based on demographics of members of the targeted group.
