Share of Voice (SEO)
Share of voice in SEO is the percentage of total possible search visibility your site captures across a set of tracked keywords, compared with competitors. It shows how much of the market's search attention you own.
How share of voice is calculated
You take a set of keywords, weight each position by its expected click-through, and express your visibility as a share of the total available across all players. The result is a single percentage that captures presence better than any one ranking.
Why use it
Individual rankings move constantly; share of voice rolls them into one trend you can report and compare with rivals. Rising share means you are winning ground across the keyword set, even if some single positions slip.
