Livestream Advertising Glossary
A plain-English glossary of livestream advertising: the ad formats, metrics, pricing models, measurement standards and delivery technology used to run and buy ads inside live streams on Twitch, Kick, YouTube Live and TikTok Live.
Ad formats
- Livestream advertising
- Placing brand messages inside live broadcasts on platforms like Twitch, Kick, YouTube Live and TikTok Live — as overlays, banners, chat messages or streamer integrations — rather than as separate ad breaks.
- In-stream ad
- An advertisement rendered inside the live video itself, as an overlay or integration, rather than as a pre-roll or mid-roll break — so it cannot be skipped or removed by ad blockers.
- Overlay ad
- A graphic ad layered on top of the live stream — a banner, corner unit or animation — that appears without interrupting the broadcast.
- Picture-in-picture (PiP) ad
- A short video ad, typically 30–60 seconds, that plays in a corner of the stream while the live content keeps running.
- Banner ad (in-stream)
- A horizontal or vertical graphic placed within the stream layout and shown for a set duration.
- Pinned chat drop
- A sponsored message, often with a tracking link, posted into the live chat and pinned for a short window such as three minutes.
- Announcement format
- The streamer verbally and visually featuring a product live — an unboxing, trial or review — so the brand becomes part of the content.
- Rich media ad
- A premium in-stream format with interactive or animated layers — countdowns, quizzes, reveals — designed to draw attention.
- Live data moment
- A branded on-screen overlay that renders a real-time data feed — match scores, race positions, weather — the moment it changes, sponsored by a brand.
- Watch party
- A sponsored co-viewing event where a streamer and audience watch content together with brand integration.
Targeting & activation
- Moment targeting
- Placing an ad based on what is happening in the stream right now — a goal, a win, a product mention — rather than only on audience demographics.
- Sponsor-moment activation
- Selling and triggering a sponsorship around a specific live moment — a clutch, a victory, a milestone — instead of a fixed logo slot.
- Contextual targeting
- Matching ads to the content, game or moment of a stream rather than to a tracked user profile — a cookieless approach well suited to live video.
Metrics & pricing
- CPM (cost per mille)
- The cost of one thousand ad impressions; the standard pricing unit for most video and display advertising.
- CPCV (cost per completed view)
- The cost of a single fully-watched video ad; useful for comparing formats with very different completion rates.
- Impression
- One instance of an ad being shown to a viewer.
- View-through rate (VTR)
- The share of ad impressions watched to completion; a high VTR indicates ads that are not skipped or blocked.
- Video completion rate (VCR)
- The percentage of video ads played all the way through.
- Click-through rate (CTR)
- The share of impressions that result in a click on the ad.
- Fill rate
- The share of available ad slots that are actually filled with a paid ad.
- Concurrent viewers (CCV)
- The number of people watching a stream at the same moment; a core measure of livestream audience size.
- Average minute audience (AMA)
- The average number of viewers across each minute of a broadcast, used to value sustained exposure.
Measurement & brand safety
- Viewability
- Whether an ad was actually visible on screen, and for how long — typically verified by an independent third party.
- Third-party measurement
- Independent verification of impressions, viewability and brand safety by a vendor such as IAS or DoubleVerify, rather than by the seller alone.
- Brand safety
- Ensuring ads do not appear alongside harmful, offensive or off-brand content; in live streams this requires real-time controls.
- Adblock-safe (ad-block immunity)
- Ads that ad blockers cannot remove because they are rendered inside the video stream rather than served as separate web requests.
- Unskippable ad
- An ad the viewer cannot skip because it is part of the live content, not a pre-roll they can click past.
- IAB Known Agents List
- An IAB Tech Lab list of legitimate automated agents; inclusion signals that a vendor operates transparently within industry standards.
Delivery technology
- Streamsense
- GingerLive's real-time AI moment-detection engine, which analyzes stream audio and video in parallel and triggers actions — ads, overlays, data feeds — seconds after a moment happens.
- Clean feed
- The production video output without on-screen graphics, used as an input source for inserting ads or overlays.
- SRT (Secure Reliable Transport)
- A low-latency streaming protocol used to deliver a production or clean feed reliably over the public internet.
- RTMP (Real-Time Messaging Protocol)
- A widely used protocol for sending a live video stream from an encoder to a platform or ingest server.
- Broadcast ingest
- Taking in a public live broadcast, or a production feed, as the source that a detection or ad system analyzes.
- Edge device
- On-site hardware that runs detection or ad insertion locally at the venue or studio rather than in the cloud.
- Browser source
- A single overlay URL added in OBS or Streamlabs that lets a streamer display in-stream ads with no further setup.
Business models & roles
- In-stream ad network
- A service that places overlay ads across many streamers' channels at once and pays them a share, letting brands run one campaign at scale.
- Streamer sponsorship
- A direct deal in which a brand pays a streamer to feature it, usually per campaign or per activation.
- Creator marketplace
- A platform where brands post campaigns and creators apply, intermediating sponsorships at scale.
