How to Evaluate a Podcast Media Kit Before Buying

1. What a Media Kit Really Tells a Buyer

A media kit is the document a show sends when it wants you to advertise with it. It bundles reach, audience profile, engagement data, ad formats, rates, and past partnerships into one place. The stated goal is to help you decide.

The practical reality is narrower. A kit is built by the seller to present its strongest case. It leads with the metrics that flatter it and stays quieter on the ones that do not. Your job is to read it for what it proves. On the other side of this transaction sits our guide to building a podcast media kit of your own.

Four numbers carry real weight. Everything else is context.

• Per-episode downloads, last 90 days. Not lifetime totals. Not the best month ever. The recent, repeatable average that predicts what your ad will reach.
• The platform that counted them. A download figure means nothing until you know the rules it was counted under. This is the check almost nobody makes, and it is covered in section 2.
• Completion rate at your ad's position. The share of listeners still present when your spot plays. This decides whether a mid-roll reaches an attentive audience or an empty room.
• Audience composition. Who listens, where they are, and what they do for a living. A large audience without your buyer in it is worth less than a small one that is entirely your buyer.

A kit presenting all four clearly belongs to a show that takes advertiser relationships seriously. If it buries or omits any of them, that absence is information. Everything that follows is about turning each section of the kit into a decision.

2. How Do You Know If Download Numbers Are Real?

This is the question a media kit rarely answers and a buyer rarely asks. It has a specific, checkable answer, and knowing it changes how you read every other figure in the document.

First, get the right number

The biggest figure on a kit is usually the one that matters least. Lifetime totals stack every request since launch, including episodes with no relation to your placement. A show advertising 12 million downloads since 2019 is describing its history. Peak months are worse, because they describe a moment the show has already failed to repeat.

What predicts your reach is the per-episode average from the last 90 days. If a kit gives you only a monthly total, divide it by the publishing frequency as a sanity check. Then ask for the real per-episode figure in writing, and watch how the show responds. A show with strong current numbers shares them willingly.

Then find out how it was counted

A download is often described as any file request, counted whether or not anyone pressed play. That was accurate a decade ago. It stopped being accurate once IAB Tech Lab published its Podcast Measurement Technical Guidelines, now at version 2.2. Under those guidelines a countable download needs roughly one minute of actual content to be requested. Bot and datacentre traffic is filtered out. Repeat requests from the same IP address and user agent are deduplicated.

So the useful question is not what a download is in general. It is whether this show's numbers were counted that way. Two words do very different work here.

Here is the move. Ask which platform hosts the show, then check that platform against the IAB Tech Lab certified companies listing. It takes under a minute and costs nothing. Certification also lapses, since companies must resubmit at least once every 12 months, so a current listing means current verification.

Independent measurement raises confidence further. Podtrac sizes audiences separately from what the hosting platform reports. Magellan AI tracks show level sponsor history, and was itself certified against version 2.2 in February 2026. A kit referencing either has been checked by someone other than the seller.

3. Is Their Listener Actually Your Buyer?

This section decides whether a deal is worth pursuing, and it is the one buyers skim fastest. Topic alignment and audience alignment are not the same thing. A cybersecurity show might serve hobbyist developers rather than the CISOs you sell to. A personal finance show might reach retail investors rather than the wealth managers you want.

The category label tells you the content. It does not tell you who is listening. A strong kit gives composition with specifics: job titles or seniority, company size, industry, geography, sometimes purchase behaviour. A weak one offers a single line like "business professionals and entrepreneurs", which describes almost everyone and qualifies no one.

When the description is vague, verify it yourself. Four checks cost nothing but time.

• Read who already advertises. Sponsors target the real audience, not the projected one. Developer tools and bootcamps mean a practitioner audience. Enterprise software and executive programmes mean the listener profile sits higher.
• Listen for how the host addresses the room. A line like "for those of you running teams of ten or more" tells you exactly who the host believes is listening. One sentence like that beats any demographic chart.
• Look at the recent guest list. Guests are booked to appeal to the audience the show actually has. A run of founders signals one listener. A run of academics signals another.
• Check the show's community. A tied newsletter, a Discord, or an active comment section. Ten posts will show you the roles people hold and the problems they raise.

If the kit's audience claim survives all four checks, it is credible. If your own listening contradicts what the kit says, trust your listening.

One more thing belongs here that kits rarely volunteer. Ask for the country level geographic split. Take a show quoting 80,000 downloads with 30 percent in your target market. As far as your campaign is concerned, that is a 24,000 download show.

4. What Your Ad Really Costs Per Person Reached

Two shows can report identical download numbers and deliver completely different value. The difference is completion, and it is the data point most kits either feature with pride or omit entirely.

Completion rate is the share of listeners who reach a defined point in an episode, usually around 80 percent of runtime. It matters because of where your ad sits. A mid-roll in a show with 40 percent completion reaches a fraction of the downloads you paid for. The same ad in a show with 85 percent completion reaches nearly everyone the download number promised.

The calculation to run before you accept any price

Multiply per-episode downloads by the completion rate at your placement point. That gives effective reach. Now divide the episode fee by effective reach and multiply by a thousand. That is your true cost per thousand people actually reached.

Worked through: a show quoting 60,000 downloads at $1,800 per episode looks like a $30 CPM. If completion at the mid-roll point is 50 percent, effective reach is 30,000 and your real cost is $60 per thousand. A smaller show quoting 25,000 downloads at $750 with 85 percent completion delivers 21,250 reached at roughly $35. The smaller show wins by a wide margin, and no rate card will say so.

Any show on a certified hosting platform, or on Spotify for Creators, can pull completion data without effort. So when a kit highlights downloads but stays silent on completion, treat the silence as a question rather than an oversight.

Signals worth weighing alongside completion

• Placement position. A high completion rate is worth nothing if your ad runs after the drop off. Ask where in the runtime your spot lands, in minutes.
• Consumption rate. The average percentage of an episode consumed. Useful when completion is not broken out separately.
• Follower growth trend. Rising means the audience is replenishing. Flat or falling means the show may be coasting on a back catalogue.
• Engagement off the feed. Newsletter opens, community activity, social response. These show whether the audience acts on what the host says, which is the behaviour your ad depends on.

A show that provides completion data quickly understands what you are buying. A show that cannot or will not is asking you to pay for reach you cannot confirm reaches anyone.

5. The Data a Good Kit Includes and a Weak One Skips

What a kit leaves out is as informative as what it puts in. Use this as your completeness checklist. A kit covering most of these was built for serious buyers. A kit missing several is asking you to commit on faith.

When a kit omits something, request it before you reply with interest. Send one email covering every gap at once, rather than three emails over two weeks. The speed and specificity of the answer is itself a data point.

A show producing a clean export in a day respects advertiser relationships. A show taking a week and answering in round numbers is telling you how the rest of the relationship will go.

6. Is the Price You Were Quoted Fair?

Podcast pricing never standardised the way search and display advertising did. Two shows with nearly identical audiences quote wildly different numbers, and that inconsistency is your opening.

One thing helps you read a rate card correctly. Published podcast prices come from rate cards rather than from a measured marketplace. So a quoted "market rate" is a seller's asking price, not an observed average. Libsyn Ads publishes $24 to $26 CPM for 60 second baked-in host-read spots. That is a useful anchor precisely because it is public. Our full breakdown of podcast CPM rates by genre, size and platform covers current ranges and where each figure comes from.

The kit reading skill that belongs here is smaller and more useful. If the kit quotes a flat fee rather than a CPM, back into the implied CPM yourself. Divide the fee by per-episode downloads and multiply by a thousand. A flat rate that looks reasonable can conceal a CPM well above market once you do the division. Flat rates are common precisely because they hide it.

If the implied number sits well above the benchmark for the show's size and category, ask what justifies the premium. Sometimes the answer is an exceptional completion rate or a genuinely scarce audience. Sometimes the rate card has not been revised in months. Either way, once you hold the number you can negotiate podcast ad rates from evidence rather than instinct.

7. What Past Sponsors Tell You About a Show

A kit's list of past partners is one of the most honest sections in the document, if you read it correctly. It is not there to impress you with logos. It answers one question: have advertisers bought this audience, and did they come back?

Returning sponsors are the strongest signal a kit can carry. Brands that find results renew quietly. Brands that find poor fit do not, and they rarely explain why in public. A show pointing to advertisers who ran several campaigns over time is showing you proof no download chart can match.

The reverse matters too. A show with two or more years of advertising history where every sponsor appears exactly once is showing you a pattern. That does not mean anything untoward. It can mean weak attribution, poor audience fit, or a host who treats ads as a transaction rather than a partnership. Either way, it earns a harder question.

Here is the move most buyers never make. Ask the show to connect you with one past advertiser willing to speak for fifteen minutes. Ask what the results looked like, whether attribution was clean, and whether they would run again. One honest reference call tells you more than any dashboard. A show that cannot produce a reference, or stalls when you ask, has told you something worth hearing.

8. How to Compare Three Kits Without Anchoring

Most buyers evaluate one kit at a time and unconsciously anchor on whichever number is biggest. That is how a 200,000 download show with a passive audience beats a 40,000 download show that matches your buyer exactly. The fix is a single scorecard so no one metric dominates.

Below is the scorecard filled in with three shows a B2B software buyer might realistically be weighing. Copy the rows and fill your own.

Show A has five times the downloads and costs nearly twice as much per person actually reached. Show B is the buy. Show C is not a rejection, it is an unanswered email, and it stays unanswered until the show fills those cells.

This is also where sourcing beats reacting. Build your own shortlist rather than waiting for kits to arrive, and every kit you read is already close to your buyer. A podcast directory covering 3M+ shows lets you filter by category, audience size, listener demographics, and sponsor activity. Then the three kits you compare are three you chose.

If you take one thing from this guide, take the order of operations. Verify the reach, verify how it was counted, verify who is listening, and only then discuss price. Most buyers reverse that sequence and negotiate hard over a number that was never real.

Do one thing in the next hour. Open the most promising kit in your inbox and send the four line request from section 5. Commit to nothing. What comes back, and how quickly, will tell you more than any cover number could.

9. Podcast Media Kit Questions Buyers Ask

What should a podcast media kit include?

A complete kit shows per-episode downloads from the last 90 days and names the platform that counted them. It gives completion or consumption rate with the threshold defined, audience composition by role and industry, and a country level geographic breakdown. Ad formats, a rate card, and named past sponsors round it out. Anything missing is a question to ask before you reply.

How do you know if podcast download numbers are real?

Ask which platform hosts the show. Then check whether that platform is listed by IAB Tech Lab as certified against the Podcast Measurement Technical Guidelines. Certified platforms apply a minimum content threshold, filter bot traffic, and deduplicate repeat requests. Numbers from an uncertified platform are self reported and should be weighted accordingly.

What is a good podcast completion rate?

There is no audited industry benchmark, because completion is reported by hosting platforms rather than by an independent body. The threshold behind the number matters more than the number. Ask where completion is measured, usually around 80 percent of runtime. Then ask where in the episode your ad sits. A high completion rate helps only if your placement lands before the drop off.

What are the biggest red flags in a podcast media kit?

Watch for lifetime or peak download totals presented as current reach, and for figures carrying no date. Missing completion data is another. So is a one line audience description that fits everyone, an absent geographic breakdown, and no named hosting platform. The last one is a sponsor history where every advertiser appears exactly once.

How do you calculate the real cost of a podcast ad?

Multiply per-episode downloads by the completion rate at your ad's position to get effective reach. Divide the episode fee by effective reach, then multiply by a thousand. That gives cost per thousand people actually reached, which is the only figure worth comparing between shows.

What should you ask a podcast before sponsoring it?

Ask for four things in one email. Per-episode downloads averaged over the last 90 days. The hosting platform and whether its measurement is certified. The recent average completion rate with its threshold defined. And a country level geographic breakdown. How fast and how specifically a show answers tells you how the rest of the relationship will run.
