What is share of voice?
Share of voice — The proportion of total available search visibility a site captures across a defined keyword set, weighted by volume and position.
Share of voice measures the proportion of total available search visibility a site captures across a defined keyword universe, weighting each position by its expected click-through rate and each query by its volume.
Its advantage over rank tracking is that it is robust to the things that make rankings misleading: personalisation, result diversity, and the fact that averaging positions across a keyword set produces a number with no meaning. Its weakness is that it is only as good as the keyword universe you define, which makes the definition itself a strategic act.
Why share of voice matters for your career
Share of voice is the metric that makes SEO legible to executives. Rankings mean nothing to a CFO; 'we hold 18 percent of available visibility in our category and our nearest competitor holds 31' means a great deal. Being able to build and defend this metric is a channel-leadership skill.

What share of voice involves day to day
- Define the keyword universe deliberately — the queries that represent the market, not the ones you already rank for.
- Weight by volume and by expected click-through at each position.
- Track against a named competitor set rather than in isolation.
- Segment by intent stage so you can see where in the funnel you are weak.
- Re-baseline when the universe changes, and say so rather than letting the trend line lie.
How share of voice comes up in interviews
Explain why you would use it instead of average position, and be candid about its main weakness — that the keyword universe is a choice and therefore contestable. That candour reads as rigour.
Evidence that lands
- A share-of-voice model you built, including how you chose the universe.
- A case where it changed a prioritisation decision that rank tracking would have got wrong.

Common mistakes
- Choosing a universe that flatters you.
- Failing to weight by position, which treats rank 1 and rank 9 as equal.
- Changing the universe silently and presenting the resulting jump as growth.
