OTT & CTV Analytics
« Back to Glossary Index
OTT (over-the-top) refers to any video content delivered directly over the internet, bypassing traditional cable or satellite distribution — and CTV (connected TV) is the device category, the smart TVs and streaming boxes, that most OTT viewing happens on. This guide covers how CTV advertising actually works step by step, how streaming monetization models differ, and how AI is helping publishers improve performance across an increasingly fragmented viewing landscape.
What Is CTV (Connected TV) Advertising?
CTV (connected TV) advertising delivers ads through internet-connected streaming devices — smart TVs, Roku, Fire TV, gaming consoles — instead of traditional broadcast signals. Unlike linear TV, CTV supports precise audience targeting, real-time delivery data, and household-level measurement.
How Does CTV Advertising Work? (Step by Step)
- A viewer starts a stream on a connected TV device — a smart TV, Roku, Fire TV, or game console.
- When the stream reaches an ad break, the app sends a real-time bid request identifying the household, device, and content context.
- Demand-side platforms bid on that impression in real time, the same auction mechanism used in standard programmatic advertising.
- An ad decisioning system selects the winning, most relevant ad for that specific household.
- The ad is delivered to the big screen with household-level targeting precision — combining programmatic precision with the brand-safe, lean-back context advertisers associate with television.
For publishers, CTV inventory commands a premium over standard digital video because it combines the targeting precision of programmatic advertising with the brand-safe, big-screen viewing context advertisers still associate with television.
OTT vs. CTV: What’s the Difference?
OTT is the content delivery method — video streamed directly over the internet rather than through a cable or satellite provider. CTV is the device category that content is watched on — a smart TV or streaming box. The same OTT content can be watched on a CTV device, a phone, or a laptop.
AVOD, SVOD & FAST: The Streaming Monetization Models Explained
AVOD (advertising-based video on demand) is free to the viewer and monetized through ads. SVOD (subscription video on demand) charges a recurring fee with little or no advertising. FAST (free ad-supported streaming television) delivers pre-programmed, linear-style channels over the internet, free to watch.
Most major media companies now run a blend of all three, which is exactly why publishers increasingly need unified analytics across all three rather than separate reporting — a gap our streaming and product analytics work is built to close.
Video Completion Rate & Engagement Metrics
Video completion rate (VCR) measures the percentage of viewers who watched an ad or piece of content all the way through, out of everyone who started watching it.
Adaptive Bitrate Streaming & Video Quality of Experience
Adaptive bitrate streaming automatically adjusts video quality in real time based on a viewer’s available bandwidth. Video quality of experience (QoE) is the broader measure of what a viewer actually experienced — startup time, buffering frequency, resolution stability.
Content Recommendation & Personalization in Streaming
A recommendation engine analyzes viewing history, engagement patterns, and content metadata to surface titles a specific viewer is likely to watch next. Recommendation quality is only as good as the underlying content tagging — a connection covered in depth by ContentIQ.
How AI Improves Streaming Platform Performance
AI is used across streaming platforms to predict and prevent buffering before it happens, to power recommendation engines that improve retention, and increasingly to forecast churn risk. Our streaming and product analytics work brings AVOD and SVOD personalization and performance monitoring together as one connected system.
