The formula

Share of voice for a brand is its mention count divided by the total mentions of all brands in the set, expressed as a percentage. SOV = (brand mentions / total mentions) * 100.

When to measure share of voice

  • After a launch or product announcement, to see if your mentions grew relative to competitors.
  • In a weekly or monthly digest, to track trend direction.
  • Before a content or marketing push, to set a baseline.
  • When reporting to a board or investor on category position.

How discatch helps

A catch per competitor at 6h or 24h, with a classified daily digest, gives the raw mention counts. The competitor-watch playbook automates it. This calculator is the offline version: paste the numbers in and see the chart.

Questions

What is share of voice?

The percentage of total mentions in a competitive set that belong to one brand. If you have 300 mentions and the set total is 1,000, your share of voice is 30%.

Does this tool call the discatch API?

No. It runs in your browser. Enter the mention counts yourself. To get the counts automatically, use the competitor-watch playbook.

How is this different from Octolens’s share of voice calculator?

Octolens’s calculator works the same way: mention counts in, percentages out. This one adds no features beyond showing the formula and linking to the playbook that automates it.

Can I track share of voice over time?

Yes. Run the calculation weekly or monthly with fresh mention counts. The competitor-watch playbook delivers the numbers on a schedule.

What sources should I count?

All sources where your audience talks about the category. For developer tools, Hacker News, Discourse, GitHub, and the web index cover the most ground.

Is 30 days the right window?

It depends on volume. Low-volume brands need a longer window to collect enough mentions. High-volume brands can use 7 days. Pick a window and keep it consistent.
