Share-of-Voice to Share-of-Voices

Traditional brand advertising has often taken recourse to strengthening the Share of Voice (SOV) of the brand in the category. Let us delve deeper into this concept here, in the context of TV advertising as an example.

So, if there are 10 brands in a category and if a certain brand advertising is seen the most then that brand is said to have the highest share of voice. Of course! there are very clear formulae based on the extensive TAM data (in case of TV) that allows one to estimate the share of voice of each brand. An estimation of GRP is essential to arrive at the SOV estimate.

Various research studies over the past have clearly established a relationship between the share of voice and Market Share and the SOV:SOM method of advertising planning is extensively adopted. In the absence of Share of Voice data; the Share of Expenditure (SOE) data too is often used for similar purpose.

Let us understand "Share of Voice" and its context a bit more.

• Traditional advertising mainly had only the brands talking about themselves and hence the sources of "voice" were limited. So, in this case we may say that since there were 10 brands - there were 10  primary sources of  Voice.
• The voice is alien or distant for every consumer. so, there was no effort to measure the "influencing power" of the voice.
• So "Share of Voice" is a "volume measure" ie it just measures the amount of advertising. So, in a volume measure the nature or the strength of the voice is not reflected.
• However, it is not a "supply measure" as "secondage of advertising" but is a "consumer side measure" since, it depicts the "amount of advertising seen". Note, that purposely I have not called it a "demand side measure" since there really is no demand for advertising - it is often thrust upon consumers. Anyways, here let us not get into whether the advertising is really wanted or seen, given the high extent of ad-avoidance behaviour which is rampant.  
• The metric of voice in each media is different and hence complex statistical techniques are required to aggregate share of voice across different media. For those who know GRP would be aware how mysterious GRPs are and how erroneous can it be to aggregate GRPs across media. 

But, the media landscape has evolved so much since the time the science of SOV:SOM based planning was scripted. The emergence of social media has started diluting the control of the brands over their advertising. The changes that have been seen are certainly here to stay and will only get more acute with the accelerated growth of digital media in the country. In such a scenario, we need to look at the principles of Share of Voice - afresh.

• If there are 10 brands in the category today, are their only 10 sources of brand messages. NO. The number of sources of brand messages today are innumerable. Hence,. there are a multitude of voices.
• Each consumer has a unique relationship with at least one of these innumerable voices and hence each voice has a definitive "influencing power" over another consumer.
• Hence, it is not the volume of voice but the number of voices which is more important.
• With the transfer of power moving from the transmitter of messages to the reciever - an exposure to a message is subject to desire and demand by the consumer. Hence, the measure of number of voices seen/ heard can be termed as a "demand side measure"
• Number of voices is a count measure and is additive across media formats - though yes, given the unique influencing power of each voice we would still need recourse to complex statistical methods to arrive at a relationship between these different voices and brand success.

Yes, I admit my thoughts are still evolving on this subject and many arguments are possible on what will happen next. However, one thing is certain that "Share of Voice' based planning as it exists today has to re-invent itself and maybe change itself to "Share of Voices" based planning.

In effect, the media plans should not be targeted to generate the highest "Share of Voice" but rather structured to activate more and more consumers to raise their voice for the brand to maximize the "Share of Voices" for the brand.

Shouting by yourself is easy but getting others to canvass for you requires winning their love and respect. That is the real challenge that the brands have to confront. If a brand wins my heart - I will always raise my voice for it.
