Podcast and YouTube Sponsorship Glossary for Advertisers

Brands spent $2.862 billion on US podcast ads in 2025¹, and US creator ad spend was projected to reach $37 billion the same year². Yet the people selling those ads use words most buyers never learned. Host read. Baked-in. Makegood. Flight.

This glossary defines the terms you'll meet when you buy ad reads, integrations or sponsorships from podcasts and YouTube channels. Each entry is short, sourced to industry glossaries, and tied to the moment in a deal where it matters.

Key takeaways

• An ad read is a sponsor message spoken inside a podcast or video, and a host read is one voiced by the show's own host.
• CPM is the cost per 1,000 downloads or impressions, so a 20,000-download episode at a $25 CPM costs about $500 per placement.
• A baked-in ad is built into the episode file at upload, while dynamic ad insertion places an ad in real time each time the episode is requested.
• A makegood is money or extra inventory owed when a purchased ad fails to meet the insertion order's terms.
• On YouTube, an integration is a sponsored segment inside a regular video, while a dedicated video is entirely about the sponsor and costs 2 to 4 times as much, per 1of10.

How to use this glossary

Terms are grouped by the stage of a deal where you'll hear them. Placement and read type come first, because they set the price. Pricing and deal terms come next. Rights, measurement and YouTube terms close it out.

Most definitions come from two industry glossaries, the Sounds Profitable podcast industry glossary³ and the Libsyn Ads podcast advertising glossary⁴. When the two differ, both views are shown.

The ten terms you'll hear first

Why we wrote it

Media List holds 1.2 million podcasts and 189,000+ YouTube channels with contact emails right now. You can use it to email hosts and creators about ad reads. Their media kits and replies use the terms below. A buyer who knows them can read a quote fast, spot what's missing and ask the right follow-up question.

New to buying? Start with our podcast advertising guide, then come back here when a term trips you up.

Placement terms

Pre-roll. An ad in the first 10% of an episode, commonly before the content begins³. Libsyn Ads simply calls it an ad at the beginning of a podcast⁴.

Mid-roll. An ad in the body of the episode, after the intro and before the outro³. Listeners are already engaged, so it usually costs the most. ADOPTER Media puts host-read mid-rolls at $15 to $30 CPM, against $15 to $25 for host-read pre-rolls⁷.

Post-roll. An ad in the last 10% of an episode, commonly after it ends³. It's the cheapest slot, at $5 to $10 CPM per ADOPTER Media⁷.

Billboard. A short ad of roughly 10 seconds at the start, middle or end of an episode⁴.

Ad spot. One ad product a show sells to an advertiser⁴.

Ad load. How much of an episode is ads. Magellan AI measured average advertiser ad load at 8.75% of episode time in Q2 2026⁸.

Share of voice (SOV). Your share of all impressions in an ad position or an episode. If an episode has four ad slots and you buy one fully, you hold 25% of the episode's SOV and 100% of that slot's³.

Availability. How many ad spots are open in a given period, which depends on how often the show publishes⁴.

Blackout. Inventory you can't buy, because no episodes are coming or the slot is already booked³.

Read types

Ad read. Any sponsor message spoken inside the content. The word covers host, producer and announcer voices.

Host read. Ad creative voiced by the podcast's host³. Magellan AI found host-read ads had a median response rate of 3.22% in H1 2026, against 2.09% for produced ads⁹.

Endorsed read. A host read in which the host shares a positive personal experience with the product and recommends it³.

Live read. Ad creative recorded live during the sponsored episode, often woven into the content³. Libsyn Ads adds that it's usually recorded into the episode for good⁴.

Producer read. An ad voiced by the show's producer rather than the host³.

Pre-produced read. Ad creative made and supplied by the buyer, with no host or producer voice³. Libsyn calls this a pre-produced ad, usually an MP3 file that is stitched into the episode⁴.

Script styles

• On script, or exact read. The host reads your script word for word⁴.
• Off script. The host delivers the ad in their own words⁴.
• Talking points. The host gets a few bullet points and fills in the rest⁴.

Most buyers of host reads send talking points. The read sounds like the host, which is the reason you bought it.

Insertion terms

Baked-in. Also called an integrated ad. The ad is built into the episode when it's uploaded, so every listener hears the same ad³. The show may re-upload the episode without it after an agreed period³.

Dynamic ad insertion (DAI). The server picks and places an ad in real time each time a listener requests the episode. It can use the listener's IP address, device, the episode and the campaign's targeting³.

Programmatic. Buying and selling ad inventory by software through supply-side and demand-side platforms, with real-time bidding³. ADOPTER Media puts programmatic and run of network CPMs at $5 to $20⁷.

Programmatic guaranteed (PG). A programmatic deal for a guaranteed number of impressions at a rate agreed in advance³.

Run of network (RON). Targeting that lets your ad run on any show in a network, not on shows you pick³.

Back catalog. Episodes released more than 30, 60 or 90 days ago³. Dynamic insertion can sell ads into them.

Limited time. An ad that runs in the episode for a set period rather than for good⁴.

Why this matters to you. A baked-in host read keeps playing as long as the episode gets listens. A dynamic ad stops when the campaign ends. Ask which one you're buying before you agree a price. Our guide to baked-in vs dynamic ad insertion goes deeper.

Pricing terms

CPM. Cost per mille, the price for every 1,000 impressions³. Libsyn gives the formula as cost divided by downloads, times 1,000⁴. A show with 20,000 downloads per episode at a $25 CPM costs about $500 per placement¹⁰.

eCPM. Effective CPM, what you actually paid per 1,000 once real downloads are in. ADOPTER Media's example is a $20 CPM on 50,000 downloads, or $1,000. If the episode gets 100,000 downloads, the eCPM drops to $10⁷.

Flat fee. A fixed price per episode or package, whatever the audience. Small shows often price this way.

CPA. Cost per acquisition, the cost to win one customer⁴.

CPV. Cost per view, a price for each single view. You'll see it mostly in YouTube and Shorts deals. Multiply it by expected views to get the fee, then compare that fee with a CPM quote.

Affiliate deal. The creator earns a commission on each tracked sale. The FTC treats that commission as a material connection that must be disclosed¹¹.

Rate card. A document listing a show's details, audience demographics, CPM and sponsorship rates, exclusivity, cancellation terms and previous advertisers³. Libsyn notes it generally sets the maximum price you may pay⁴.

Media kit. The show's sponsor-facing pack, which usually holds the rate card plus audience and reach details.

Knowing the words gets you a fair price. It doesn't get you the rate card. For that you need the host's email, and for small shows it's rarely on the ad marketplaces. Agencies and hosting platforms often want about 5,000 US downloads per episode before they sell a show¹².

Deal terms

Insertion order (IO). A signed agreement between seller and buyer that sets the campaign terms, obligations and price³. Libsyn calls it the final step in the proposal process⁴. See our podcast sponsorship agreement and IO template.

Flight. The length of a campaign. For dynamic ads it sets start and stop times. For baked-in ads it lists each episode's drop date³.

Makegood. Money or extra inventory owed when a purchased ad fails the IO's terms. It can cover one spot or a whole campaign³.

Exclusivity. Protection from brands in the same IAB content category, on a whole show or one episode, during the campaign and sometimes after³.

Cancellation clause. The agreed window in which either side can cancel the rest of a contract³.

Spot buying. Buying 100% share of voice for one ad position in one episode, for good or for a set period³.

Episodic buying. Buying a set number of impressions in one or more named episodes³.

Upfronts. Talks in late Q3 or early Q4 between advertisers or agencies and shows or networks that set pricing for the next year's annual deals³.

Delivery time. How long the show needs to get an ad live after you buy it⁴.

Rights terms

These come up mostly with YouTube and video podcasts, when you want to reuse a creator's content.

Usage rights. A paid license to run the creator's raw files as an ad from your own account. The ad then comes from your brand⁶. 1of10 puts usage rights at plus 30% to plus 100% of the base fee, scoped by length of time and platform⁵.

Whitelisting. Permission from the creator for your brand to run paid ads from the creator's own profile. You control budget, targeting and dates, not the content⁶. Existing likes and comments carry over⁶.

Spark Ads. TikTok's tool for whitelisted ads, which uses an authorization code the creator makes in the app⁶.

Partnership Ads. Meta's tool for the same thing, formerly called Branded Content Ads⁶.

Category exclusivity on YouTube. 1of10 puts it at plus 20% to plus 30% for 30 days and plus 50% or more for 90 days⁵.

Put every right you want in the contract. If it isn't written down, assume you don't have it.

Measurement terms

Download. Under IAB guidelines, one download per episode for each unique IP address and device pair in 24 hours, once at least 60 seconds of audio has reached the device³. The IAB Tech Lab measurement guidelines set these rules, now at version 2.3¹³.

Ad delivered. The podcast version of an impression. It counts when the part of the episode with the ad is sent to a listener in an IAB-certified download³.

Promo code. A code the host mentions that listeners enter at checkout. Redemptions show how the campaign did⁴.

Vanity URL. A short, show-specific web address, such as yourbrand.com/show. Libsyn Ads recommends a unique landing page for each show¹⁴.

HDYHAU survey. How did you hear about us. A question after purchase. Fairing says these surveys tend to get 40% to 50% response rates¹⁵.

Attribution pixel. A tag that matches people who heard the ad to later actions on your site or app³. Fairing says pixel attribution is only about 50% accurate¹⁵.

Response rate. In Magellan AI's reports, the share of reached listeners who visit the advertiser's site within 30 days. The H1 2026 median was 2.23%⁹.

Brand lift. A survey study that compares people who heard or saw the ad with people who didn't, to measure recall and awareness.

YouTube sponsorship terms

Integration. A sponsored segment inside a regular video. 1of10 calls the 60-second integration the standard unit⁵, priced at about $10 to $50 per 1,000 expected views⁵.

Dedicated video. A video made entirely about the sponsor. 1of10 prices it at 2 to 4 times an integration⁵. ADOPTER Media calls it premium inventory¹⁶.

Shoutout. A quick mention, often before the video starts¹⁶. 1of10 prices a 30-second shoutout at 0.5 to 0.7 times an integration⁵.

Sponsored Short. A sponsor feature in a YouTube Short, priced at 0.25 to 0.5 times an integration by 1of10⁵.

Full integration. ADOPTER Media's term for a deal where your product is part of the content itself¹⁶.

Paid promotion disclosure. Creators tell YouTube a video includes paid product placement, sponsorship or endorsement, and YouTube shows a label on it¹⁷. The FTC says the disclosure should also be in the video itself, not just the description¹¹.

Average views. The number YouTube deals are priced on. ADOPTER Media says the minimum investment is almost always $1,000, even on small channels¹⁶.

Simulcast. A podcast that also publishes its episodes as video on YouTube. ADOPTER Media puts YouTube simulcast ads at $10 to $30 CPM⁷. Magellan AI reported that podcasts which simulcast to YouTube had an 8% higher renewal rate¹⁸.

Video podcast. A show with a video version. In Magellan AI's H1 2026 data, video podcasts had a 2.05% median response rate against 1.88% for audio-only shows, and a 4.50% lead conversion rate against 2.57%⁹.

Renewal. Buying the same show again after a test. Libsyn Ads notes many buyers reorder for a full quarter or half year once a show works¹⁴.
