SOV (Share of Voice) is the share of visibility a brand holds against its competitors for a given set of terms or within a category — the proportion of impressions or placements that belong to you.

What is SOV?

SOV (Share of Voice) is the share of visibility a brand holds against its competitors for a given set of terms or within a category — the proportion of impressions or placements that belong to you.

It is available in two flavours that together tell a coherent story. Paid share of voice reflects advertising dominance: what proportion of the available impressions in that space your campaigns are winning. Organic share measures how often your products appear in the organic positions that matter. Read together, they show whether a brand is buying its presence, earning it, or both.

Why the two measures belong together

A brand with a large paid share and a weak organic share is renting its visibility — the moment the budget stops, so does the presence. A brand with a strong organic share and modest paid share owns its position and spends less to defend it. The most efficient mature accounts show both, with advertising concentrated where it defends or builds rather than where organic already carries the load.

Tracking the ratio over time is more informative than either number alone. Rising organic share with flat paid share means the content and ranking work is paying off, which is the healthiest direction a brand can move in — and falling organic share with rising paid share is the pattern worth intervening on early.

Using it to make decisions

At category level it sizes the competitive position: how much of the conversation a brand actually occupies versus the rivals it meets on every search page. At term level it identifies the specific battlegrounds where the brand is underweight — which is where a deliberate push, organic or paid, has the clearest rationale.

And it keeps advertising honest. Campaign reporting shows what you spent; share of voice shows what you got for it relative to everyone competing for the same attention. A rising spend that buys a falling share is a signal that the auction is being lost, not that the budget needs increasing.

SOV (%) = (Your Impressions ÷ Total Category Impressions) × 100Calculated for a defined term set or category. Paid and organic shares should be tracked separately.

In practice

A brand measures its paid and organic share across its core terms each month. Organic share climbs steadily as listing content and review depth improve, while paid share stays flat — evidence that the organic position is being earned rather than rented, and that the advertising budget is defending rather than subsidising. The mix is left deliberately in place.

⚠️ Watch out. Reading the paid number as the whole picture. A brand sees strong advertising share, concludes it dominates its category, and misses that its organic presence is eroding underneath the spend. When a budget squeeze arrives, the visibility goes with it — because none of it was owned.

💡 Harpy tip. Track both shares over time and watch the direction: rising organic with steady paid is the healthy pattern; falling organic with rising paid is the warning. Use term-level share to decide where a deliberate push is worth funding.

How Harpy Media helps

Competitive visibility is part of our growth work: paid and organic share tracked separately, the balance between them used to judge health, and advertising concentrated where it defends real positions.

SOV FAQ

What is share of voice on Amazon?

The proportion of visibility your brand holds against competitors for a set of terms or in a category — measurable in paid terms (advertising impressions and placements) and organic terms (search presence).

Why track paid and organic separately?

Because they indicate different things: paid share shows what your budget is buying now; organic share shows what you own. The ratio between them is the real measure of competitive health.

What is a good share of voice?

There is no universal target — it depends on the category’s concentration. What matters is the trend relative to competitors and the direction of the organic share, which indicates whether position is being earned.
