Share of Voice Calculator

Share of voice measures how much of the available organic visibility your domain owns across a set of keywords. It is not a count of rankings. A domain that ranks first for ten tiny keywords can still lose to a competitor that ranks third for one large one.

The calculator weights each keyword by monthly search volume and by the click-through rate of the position the domain holds. A position-one result is expected to win about 31.7% of clicks. Position two wins 24.7%, position three 18.6%, and the curve keeps falling to about 2.4% at position ten. Positions eleven to twenty earn between 1.8% and 0.6%.

Expected clicks = monthly search volume × position CTR. Your share of voice = your expected clicks ÷ the expected clicks of every domain in the table. A blank cell, a dash, or a zero means the domain does not rank, so that keyword adds nothing to its total.

Use a consistent snapshot. Pull the same country, device type, and date for every domain, otherwise the percentages compare different SERPs. Re-run the table after a content push to see whether your share moved, and check which competitor gained the points you lost.

The click curve is an industry estimate, not a Google number. Google does not publish CTR by position, and the real rate changes with query intent, SERP features, and branded demand. Treat share of voice as a directional metric for comparing domains on the same keyword set, not as a traffic forecast.
