Primary Data Sources

Metrics that Matter
 Engagement e.g. youtube comments/likes; twitter retweets
 Reach Youtube views, twitter followers etc
 Target demographic & Interest e.g. males aged 25-34
 Channel(s) e.g. Youtube for a video campaign
 Indices: H-index, M-index, G-index

H-index
Definition:
“A scholar with an index of h has published h papers
each of which has been cited in other papers
at least h times. Thus, the h-index reflects
both the number of publications and the
number of citations per publication.”
H-index = 116
H-index = 116

The H-Index is a means of measuring influence
Twitter Author-level metric – measures: productivity (tweets) & engagement
(retweets)
Tweet Retweeted Retweeted
1 10 25
2 8 8
3 5 5
4 4 3
5 3 3
200
Last 200 tweets
H-index = #of tweets which have been
retweeted H or more times
H-index = 4 H-index = 3

Twitter H-index
Twitter H-index = 10 Twitter H-index = 5

M-Index
 The m-index is defined as h/n, where n is the time delta in years between the
last tweet and the 200th tweet & h is the h-index
 M-indices tend to be higher than H or G-indices as the time taken to tweet
200 times could be days in some circumstances

G-Index
The g-index can be seen as the h-index for an averaged retweet count,
largest number n of highly engaged tweets for which the average number of retweets is at least n
The index is calculated based on the distribution of retweets
received by a given authors tweets, such that given a set of
tweets ranked in decreasing order of the number of
of retweets that they received, the g-index is the unique largest
number such that the top g tweets received together at least g2
retweets.

Objective
Validate a set of influencers that can be used
to market a food brand on Youtube, or
Twitter, targeting mixed audience, primarily
females in age group 25-34, intrested in food
& parenting?
