## Definition

Post-roll ads are video advertisements that appear after the main content concludes, designed to capitalize on viewer completion and engagement. These placements are particularly effective for direct response and call-to-action messaging, as viewers who complete content are typically more invested and likely to engage. Post-roll ads often feature interactive elements and clear conversion paths to maximize action rates.

## Examples

- Interactive end cards with clickable product galleries
- Direct response video ads with strong calls-to-actions
- Multi-option choice boards letting viewers select their next content
- Companion banner integration with post-roll video messaging

## FAQs

### What are post-roll ads?

Post-roll ads are video ads that play after the main content finishes. Because they run once the viewer has already gotten what they came for, they reach a satisfied, fully-engaged audience — but also one whose attention is naturally drifting toward leaving, so post-roll trades guaranteed prior engagement for lower staying power than pre- or mid-roll.

### When are post-roll ads effective?

When you want to reach viewers who completed the content — a self-selected, highly engaged group — and a follow-on message or CTA makes sense after they've finished. They work for re-engagement, related offers, or a call to action that builds on the content just watched. They're weaker for broad reach (many viewers leave before the end) or when capturing attention up front is the priority.

### Post-roll vs pre-roll and mid-roll — how do they compare?

Pre-roll reaches everyone at the start (high attention, high skip intent); mid-roll reaches committed mid-content viewers (good completion, interrupts the experience); post-roll reaches viewers who finished (maximum prior engagement, but attention is leaving). Reach is largest for pre-roll and smallest for post-roll. Choose by goal: pre-roll for reach, mid-roll for engaged attention, post-roll for a follow-on message to finishers.

### Why is completion intent important for post-roll?

Because only viewers who watched to the end see a post-roll ad, the audience is pre-qualified as engaged and interested in the topic — valuable for relevant follow-on messaging. The flip side is that having finished, they're primed to move on, so the post-roll must grab the residual attention quickly with a clear, relevant CTA before they navigate away.

### Do post-roll ads have lower engagement?

Often, yes, relative to pre- and mid-roll, because the viewer's goal (watching the content) is already complete and their attention is shifting to whatever's next. That's not a reason to avoid post-roll — it reaches a uniquely engaged, self-selected audience — but it does mean the creative must be concise and immediately compelling, and you should weigh its narrower reach when planning the buy.
