In-stream video ads on Meta platforms like Facebook and Instagram integrate directly into video content, appearing before, during, or after videos. These ads work well because they engage users already watching videos, often with sound on, leading to higher brand recall (+8.8 points) and improved campaign metrics.

Key highlights:

  • Ad Types: Skippable (after 5 seconds) and non-skippable (up to 15 seconds).

  • Performance Metrics: Focus on ThruPlays (15-second views), completion rates, and cost metrics like Cost per ThruPlay.

  • Creative Tips: Hook viewers in the first 5 seconds with clear branding, strong visuals, and sound.

  • Audience Insights: Use data to identify high-performing segments and refine targeting with AI tools.

Brands like Maybelline and Heineken have seen success by optimizing creative elements and leveraging data insights. Tools like AdAmigo.ai further streamline ad management, enabling smarter targeting and faster scaling.

Key Performance Metrics for In-Stream Video Ads

Meta In-Stream Video Ads Performance Metrics and Impact

Meta In-Stream Video Ads Performance Metrics and Impact

To fine-tune your campaigns, it's crucial to focus on the right metrics. These metrics not only help identify successful strategies but also guide adjustments in creative execution and audience targeting using an Ad Performance Analyzer. Meta's in-stream video ads provide insights into viewer engagement, helping you gauge whether your ad spend is delivering results.

View Metrics: Views, ThruPlays, and Completion Rates

When it comes to in-stream ads, ThruPlay stands out as a key metric. It tracks how often a video is watched to the end (for videos under 15 seconds) or for at least 15 seconds (for longer videos). While 2- and 3-second views show brief exposure, ThruPlay reveals deeper engagement - indicating that viewers stayed long enough to absorb your main message.

Completion rates, on the other hand, highlight where viewers drop off - whether at 25%, 50%, 75%, or 100% of the video. High completion rates suggest your content resonates with the audience. A great example is Maybelline New York (France), which ran an in-stream campaign in November 2022 to promote its "Curl Bounce" mascara. Targeting women aged 15–34, the campaign achieved a 10% lift in ad recall and a 7% boost in brand awareness. According to Celine LY, Digital Brand Activation Manager, strong completion rates were a key factor in the campaign's success.

"The in-stream placement demonstrated outstanding completion rate and is therefore a very qualitative touchpoint we would consider in our future campaigns."

Metrics like ThruPlay and completion rates also help evaluate the strength of your video’s opening hook. A weak hook may lead to brief views, while a strong one keeps viewers engaged, ultimately influencing cost-related performance metrics.

Cost Metrics: Cost per Completed View and Cost per ThruPlay

Cost metrics like Cost per Completed View (CPCV) and Cost per ThruPlay focus on the quality of engagement rather than fleeting impressions. These metrics reveal how effectively your creative captures and holds attention.

Meta’s research highlights the impact of creative quality on costs. For instance, a 10% improvement in Creative Quality Score - measuring adherence to best practices like early branding and optimizing for sound - can lead to a 17.4% drop in CPCV, a 4.7% reduction in CPM, and a 66% higher Return on Ad Spend (ROAS). Aude Gandon, Global CMO at Nestlé, emphasized this connection:

"We just got data from Meta showing that ads with a higher Creative Quality Score received 66% higher ROAS."

If your Cost per ThruPlay starts climbing, it could signal that viewers are skipping the ad early or losing interest. To counter this, refine your creative by using strong visuals, clear text overlays, and compelling audio cues. These adjustments can help reduce costs and improve overall engagement.

Analyzing Viewer Engagement and Drop-Off Points

Figuring out where viewers stay engaged - and where they drop off - is key to improving your in-stream video ads. Meta offers detailed data that highlights which moments grab attention and which ones cause viewers to skip or scroll away. By studying these patterns, you can fine-tune your ad creative for better results.

Early Engagement: Hook Rate and Initial Views

The first few seconds of your video ad are everything. They determine whether viewers stick around or move on. One important metric to watch is the Thumbstop Rate (also called hook rate), which measures how many 3-second video plays you get compared to total impressions. If your thumbstop rate is low, it’s a sign your opening frames aren’t grabbing attention.

Since viewers can skip after 5 seconds, a drop-off at this point points to a weak hook. To fix this, make sure your brand identity and value proposition are clear and front-loaded in those critical first 5 seconds. Unlike feed ads, in-stream ads are often watched with sound on, so use audio to your advantage. Music, voiceovers, or sound effects can help pull viewers in during this short window of opportunity.

"For stream environments, leverage audio and video cues to hold attention during longer views."

Tracking Retention Through Completion Stages

Once you’ve captured attention, the next step is tracking how long viewers stay engaged. Retention metrics at key points - like 25%, 50%, 75%, and 100% - show where your narrative might be losing its grip. If there’s a sharp drop-off at any stage, it’s a signal to tweak your messaging or creative elements.

For ads longer than 15 seconds, Meta cuts the video at the 15-second mark, requiring viewers to click a context card to keep watching. This creates a natural point where engagement might dip. If retention drops significantly here, it could mean your message is too complex for the format, or your value proposition isn’t strong enough. To counter this, make sure your key message - whether it’s your brand story, product benefit, or call-to-action - lands before the 15-second cutoff.

In-stream ads generate approximately 0.07 brand recallers per second of attention. That means every second matters. By analyzing retention data in Meta Ads Manager, you can pinpoint weak areas in your creative and make adjustments to pacing, visuals, or messaging. These insights help you refine your campaigns for better engagement and stronger outcomes.

Improving Creative and Targeting Based on Performance Data

Using Performance Data to Improve Video Creative

Pinpoint where viewers drop off and tweak your video elements as needed. Start by linking your creative features - like branding placement, text overlays, and visual focus - to performance stats. For example, in 2024-2025, Heineken tracked four key creative elements against brand uplift. By monitoring their Creative Quality Score, they boosted creative quality by 50% and saw a 50% increase in brand value on Facebook.

To keep viewers engaged, use bold, concise text overlays and focus tightly on key characters. Make sure your branding is both visible and audible within the first few seconds. Tools like Meta's Image Animation and Video Expansion let you quickly create new variations without needing costly reshoots, helping you test and scale successful ideas faster. Performance data doesn’t just shape your creative - it also highlights which audience segments are worth targeting.

Refining Audience Targeting with Performance Insights

Performance data can also sharpen your audience targeting. By reviewing completion rates and costs across different segments, you can identify which audiences deliver the best results - those with high completion rates and lower costs per incremental outcome. These are the groups where scaling your budget could pay off.

In May 2025, boohooMAN, a men’s clothing retailer, tested a strategy pairing creator-led partnership ads with their usual approach. By analyzing performance data, they discovered this method led to a 35% increase in new customers compared to brand-only ads. They also tapped into the fact that 40% of people rely on creator recommendations on Instagram when shopping, using this insight to refine their targeting.

Meta’s Opportunity Score in Ads Manager offers AI-driven suggestions to optimize campaigns. Advertisers who follow these tips often see a median 5% cut in cost per result. Additionally, Meta's Advantage+ suite automates audience targeting and diversifies creative assets, helping brands achieve better outcomes. Those using these tools report earning an average of $4.52 in revenue for every dollar spent - a 22% improvement over standard campaigns. As the system learns from your data, it hones in on the segments most likely to convert, freeing you up to focus on broader strategy.
