What is ‘Share of Voice’ in Audio Media and How to Measure It

Share of Voice (SOV) is the percentage of the total conversation in your category that belongs to you rather than your competitors. In audio, it measures how often your name surfaces across the podcasts your market actually listens to, weighted by the reach of the shows carrying you. If ten people in your space were named across podcasts last quarter and you accounted for three of every ten mentions, your Audio SOV is 30 percent. The number matters because in a crowded category, the operator who is talked about most is presumed to be the leader, regardless of who is technically best. SOV turns that presumption into a figure you can track, benchmark against named rivals, and defend a budget with.

Why this number decides category leadership

Audiences do not rank you against a spreadsheet of features. They rank you by how often your name reaches them with authority attached. Podcasts are where that authority gets minted, because a guest spot or a third-party mention carries the host’s implied endorsement.

When a prospect hears your name on three shows they trust and never hears your rival, you have already won the comparison before a sales call happens. SOV is the leading indicator of that outcome. It moves before revenue does, which is exactly why it is worth measuring.

The reputational risk runs the other way too. If a competitor is quietly accumulating mentions across the shows your buyers listen to, they are building a narrative lead you cannot see in your own analytics. By the time it shows up in your pipeline, the gap is months old.

Text SOV and Audio SOV are not the same measurement

Most operators track Text SOV: mentions across articles, blogs, news, and social posts. It is easy to measure because text is indexed and searchable the moment it publishes. It is also the most crowded and least trusted channel you have.

Audio SOV behaves differently in three ways that change its value:

• Higher trust per mention. A spoken endorsement from a host the listener chose to follow carries weight a banner ad or a press quote cannot match.
• Longer shelf life. A print feature decays in a week. An evergreen episode keeps surfacing your name in search and recommendation for years, so a single strong appearance compounds.
• Historically invisible. Audio was not indexed, so most people had no way to count it. That blind spot is precisely where the advantage sits.

The practical takeaway: a high Text SOV with a low Audio SOV means you are loud in the cheap channel and quiet in the channel that converts. That is a fixable, and expensive, imbalance.

How to actually measure your Audio SOV

The measurement is a ratio, and the discipline is in defining the numerator and denominator honestly. Sloppy boundaries produce a flattering number that means nothing.

1. Define the category set

List the specific names you compete with for attention. Not the whole industry. The four to eight rivals a buyer would realistically consider alongside you. This named set is your denominator.

2. Define the show universe

Decide which podcasts count. Counting every show that exists inflates the noise. Count the shows your buyers and your category actually listen to, plus any high-reach general shows that touch your space.

3. Count mentions, then weight them

A raw mention count is a starting point, not the answer. A name dropped on a show with 200 listeners is not equal to a name discussed for ten minutes on a show with 40,000. Weight each mention by:

• Reach of the show carrying it.
• Depth, a passing reference versus a full guest segment.
• Sentiment, since a critical mention is not the same asset as praise.

4. Calculate and trend it

Your weighted mentions divided by the weighted total across your named set gives your Audio SOV. The single figure is useful. The trend line over 90 days is where the intelligence lives, because it tells you whether you are gaining or ceding ground.

The honest part: doing this by hand is brutal. It means transcribing or listening to dozens of shows, catching every name variant, and estimating reach for each one. This is the work nobody admits to skipping, which is why most SOV numbers floating around are guesses. Continuous monitoring exists to remove that labor. Seraphina Podcast Intelligence tracks every mention across the shows in your space, attaches reach and sentiment to each one, and renders the comparison against named rivals as a live index rather than a quarterly scramble.

Benchmarking against named rivals, not the field

An SOV number in isolation tempts you into vanity. The figure only earns its keep when it sits beside a specific competitor’s figure.

Run the comparison rival by rival. You are looking for three things:

• Who leads, and by how much. A 5 point gap is a sprint. A 25 point gap is a strategy problem.
• The shows driving their lead. Almost always, a rival’s SOV advantage traces back to a handful of high-reach shows you are absent from. That is their open door and your whitespace.
• The narrative they are claiming. SOV is not only volume. It is which ideas a rival is attaching their name to, repeatedly, until the category credits them with it.

This is the move most analysis skips. Do not just measure that a competitor is louder. Map exactly which shows they appear on that you do not, and pitch into that specific whitespace. A competitor’s media footprint is a list of pre-qualified shows that book people like you. The booking decision has already been made in your favor by the fact your rival passed the same bar. The mechanics of running that footprint analysis and turning it into bookings are covered in our briefing on podcast PR and guest strategy.

Using SOV to justify and direct PR spend

PR budgets get cut first because they are the hardest to defend. SOV fixes that by giving you a metric that connects spend to a measurable shift in category position.

The argument writes itself once you have the baseline. We hold 18 percent Audio SOV against a leader at 34 percent. The gap is concentrated in six high-reach shows. Booking four of them over two quarters closes roughly half the gap. That is a budget request a finance team can evaluate, because it names the input, the mechanism, and the expected movement.

SOV also redirects spend you are already wasting. If you are paying for placements in channels that never move your audio number, the data tells you to stop. Concentrate the budget on the shows that actually carry weight with your buyers.

The discipline to maintain: measure SOV before and after every campaign. A PR push that does not move your Audio SOV against named rivals did not work, regardless of how many placements it generated. This is the accountability most agencies would rather you not apply.

What a rising SOV is worth in pipeline

The point of the number is not the number. It is what a higher number does to your commercial position. Three effects compound:

• Inbound shifts. When your name surfaces repeatedly across trusted shows, prospects arrive already convinced. The sales cycle shortens.
• Outbound warms. Cold outreach lands differently when the recipient has already heard you discussed favorably. Audio SOV is the quiet reason some emails get answered.
• Partnership leverage. A visible lead in category conversation makes you the obvious partner, not the one asking for the favor.

That last point is where appearances pay out beyond the listen. A strong guest spot is a relationship opened, and the follow-up is where it converts. We cover the exact sequence for converting an appearance into a deal in our briefing on following up after a podcast interview to secure partnerships.

Frequently Asked Questions

What is a good Audio Share of Voice score?

There is no universal benchmark, because SOV is only meaningful relative to your named competitors. In a category with five serious players, an even split is 20 percent each, so anything above that is a lead. The figure that matters is your gap to the specific rival ahead of you, and the direction of that gap over time.

How is Audio SOV different from podcast reach or downloads?

Reach and downloads measure the size of an audience. Audio SOV measures how much of the category conversation across those audiences belongs to you versus rivals. A show can have huge reach and contribute nothing to your SOV if your name never comes up on it. SOV is about presence in the conversation, not the size of the room.

Can I measure Audio SOV without a tool?

You can, but it is heavy manual work. You would need to identify every relevant show, listen to or transcribe episodes, catch every mention of you and each rival, estimate reach for each show, and weight everything consistently. Most people who try this give up after one quarter, which is why continuous monitoring exists to run it as a live index instead.

Should I count negative mentions in my SOV?

Count them, but track them in a separate lane. A critical mention still occupies space in the conversation, so it affects raw volume. It is not the same asset as praise, so weighting by sentiment keeps a string of negative coverage from masquerading as momentum.

How often should I measure it?

Treat the trend as a rolling 90 day window and review it monthly. Audio moves slower than social, so daily tracking creates noise without insight. The exception is around a campaign or a competitor’s media tour, when a tighter cadence shows you the movement in near real time.

How does SOV connect to actual revenue?

SOV is a leading indicator. It moves before pipeline does, because category presence shapes how prospects evaluate you before they ever reach out. The cleanest way to prove the link is to track SOV alongside inbound volume and sales cycle length over the same period and watch them move together.

What if a rival dominates one specific show?

That show is either their owned relationship or your open door. If it reaches your buyers, treat their repeated presence as proof the show books people in your category, and pitch into it with an angle they have not claimed. Owning the second voice on a show your rival treats as home territory is a direct way to erode their lead.

Your next move

Establish your baseline. Name your four to eight real competitors, define the shows your buyers actually listen to, and get an honest weighted figure for where you stand against each rival today. That single number reframes every PR decision you make for the next year.

Then watch the trend and act on the gaps. The shows driving a rival’s lead are a ready-made list of places to pitch, and the narratives they are claiming are the ones to contest before the category credits them permanently.
