Share of voice is your brand's portion of the mentions, reach or conversation in a category, compared with the competitors you track.
Why it matters
It puts your numbers in context. Growing reach in a market that is growing faster still means you are losing ground; share of voice shows that.
A simple way to track it
Pick three to five competitors and a set of category keywords. Each month, count mentions (or reach) for each brand and divide yours by the total. Track the trend rather than the absolute number.
