How to buy podcast ads without a media agency

Podcast advertising is one of the last channels where a brand can still buy directly, talk to a real human on the other side, and keep the margin that would otherwise disappear into a media plan. US podcast ad revenue reached more than $2.4 billion in 2024, up 26.4% year over year according to the IAB, and a growing share of that spend now flows through self-serve and direct relationships rather than traditional agencies. If you have a clear product and a willingness to do the work, you can run a credible campaign yourself. This guide is honest about both halves of that sentence: the work, and the reward.

The instinct to hire an agency is understandable — podcast buying looks arcane from the outside. But most of the mystery is packaging. Once you can name what an agency does, price what it costs, and follow a simple process, the case for going direct on a focused campaign becomes hard to argue with. Let's take those three things in order.

What a media agency actually does

Before you decide to skip one, it helps to name what you would be replacing. A good podcast agency does four distinct jobs, and they are not interchangeable:

• Sourcing and vetting — knowing which shows fit your product, which sell house ads versus premium host-reads, and which have audiences that actually convert.
• Negotiation — pushing CPMs down, securing added value, and holding sellers to make-goods when downloads underdeliver.
• Trafficking and operations — briefing hosts, approving scripts, delivering assets, and keeping a dozen insertion orders straight.
• Measurement and reporting — standing up pixels or promo codes, reading the results honestly, and deciding what to renew.

Notice that only two of these require scale or relationships. The other two are process. That distinction is the whole argument for going direct.

The margin you are paying for

The classic agency arrangement is a 15% media commission, though real rates range from 10% to 20% and are frequently paired with a monthly retainer. The mechanics are worth understanding because they are deliberately quiet. Media vendors bill the agency a net rate; the agency bills you a gross rate that is grossed up by about 17.65%. The gap is the commission. You rarely see it itemized, which is exactly why it is easy to overlook.

Only two of an agency's four jobs actually require scale. The other two are process — and process is something a small team can own.

A worked example: the money you keep

Say you want to run host-read mid-rolls on a show with 50,000 downloads per episode at a $25 host-read CPM. The math per insertion is straightforward:

• 50,000 downloads ÷ 1,000 = 50 CPM units
• 50 × $25 = $1,250 per episode
• A 10-episode flight = $12,500 in net media

Now add an agency at 15%. Grossed up, that same flight bills at roughly $14,700 — about $2,200 you paid to have someone else place a buy you could have placed with three emails. Scale that logic to a $100,000 annual podcast budget and the commission alone is $15,000 to $17,600, enough to fund two or three additional shows or a proper measurement setup. That is the prize for buying direct.

The direct playbook, step by step

Doing it yourself is less mysterious than it looks. A workable sequence:

• Shortlist by fit, not just size. Pick shows whose audience overlaps your buyer. A smaller, tightly matched show usually beats a large general-interest one.
• Ask for the media kit and the net rate. Sellers expect this. Confirm downloads, CPM, placement (pre-, mid-, or post-roll), and whether the read is host-read or produced.
• Negotiate on volume and commitment. Multi-episode flights, category exclusivity, and prompt payment are your levers.
• Insist on IAB-certified numbers. Reputable sellers measure to IAB Tech Lab guidelines — a 60-second minimum to count a listen and a 24-hour deduplication window. If a seller cannot say how they count, treat their downloads with suspicion.
• Set up attribution before you launch, not after. A tracking pixel or a clean promo code decided up front saves you from arguing about results later.

Where doing it yourself gets hard

Honesty matters here, because the failure cases are real. Direct buying breaks down when:

• Your buy gets big. Coordinating 30 shows across five networks is a full-time operations job, and the errors — missed insertions, wrong scripts, unbilled make-goods — start to cost more than the commission would have.
• You lack leverage. A first-time direct buyer has less negotiating power than an agency spending millions a year with the same network.
• Nobody owns it internally. Podcast ads reward iteration. If no one on your team can read the numbers and adjust, the channel quietly underperforms.

When you still want an agency

Keep the agency for what it is genuinely good at: large, complex, multi-network campaigns; categories where relationships unlock inventory you cannot reach cold; and moments when you need to move fast without building internal capability. A seasoned buyer also brings pattern recognition — they have seen which shows overpromise and underdeliver, and that judgment is worth real money on a big plan. The mistake is defaulting to an agency for a focused campaign on a handful of well-chosen shows, where you are paying scale pricing for a job that does not need scale. A useful test: if you can list your target shows on one page and brief them in an afternoon, you almost certainly do not need to rent someone else's Rolodex to buy them.

Buying direct without flying blind

The reason most brands hand this to an agency is not the negotiation — it is the fear of sourcing the wrong shows and reading the results badly. That is exactly the gap 10AM Media's Ads Marketplace is built to close. Instead of a keyword search that surfaces the biggest shows, it matches your product to shows by meaning, so a small, tightly relevant podcast surfaces alongside the obvious ones. You see real, IAB-aligned audience numbers, place the buy directly with the show, and keep the margin an agency would have taken. You get the leverage of a platform without giving up the economics of going direct.
