ZERO to 1
The greatest number of consumers of
any brand are very light buyers, and
they contribute significantly to sales
volume, so for most brands the
biggest opportunity for growth comes
from taking people from buying it zero
times to buying it once in a typical
purchase cycle.

16%
As little as 16% of all advertising is both remembered and correctly
attributed, meaning that 84% of advertising spend could be wasted.
In a study by the Ehrenberg-Bass Institute of a sample of 143 TV ads,
avg. ad recall was found to be around 40%, and avg. branded recall
was 40% of that.

If you want people to remember your
key message, you’re best delivering 1
message not 2+. Analysis of the Link
database shows that the more
messages you try and communicate, the
less likelihood there is of any single
message being communicated.

share growth per 10 pts of excess SOV.

market and brand size, the 2nd most
important driver of advertising
profitability, on average multiplying
profitability by a factor of 12 according to
Data2Decisions.

Highly creatively-awarded campaigns can
achieve around 16 times the efficiency of
non-awarded campaigns, meaning they
drive market share growth 16 times more
strongly per point of excess SOV, whilst
less awarded campaigns achieved just
under 10 times the efficiency of
non-awarded campaigns.

60/40
Brands should spend around 60% of their
budget on brand-building activity and
40% on activation for maximum
effectiveness. Too little brand activity and
the brand equity needed to drive sales in
future will not accumulate. Too little
activation and the brand will not be
exploiting the sales potential of brand
equity as it accumulates.

0.5%
Excess share of voice (ESOV = SOV -
SOM) is an important contributor to the
level of growth. On average, a 10 point
difference between SOV and SOM leads
to 0.5% of extra market share growth.
So a brand with a share of 20.5% with
an ESOV of 10 points would grow to
21% market share over a year.
