What is Share of Voice (SOV)?

How to calculate SOV

Share of voice measures the percentage of media spend compared to the total media expenditure for the product, service, or category in the market. 

Share of voice is calculated by taking the campaign's proposed impressions divided by the minimum number of impressions available in the market and multiplying this by 100. As the proposed impressions of a campaign are directly correlated to the amount you are spending, the more money spent the higher percentage of share of voice you will have.
