Video Completion Rate
What AdGradr checks
Section titled “What AdGradr checks”AdGradr pulls videoQuartileP100 (viewers who watched 100% of the ad) and videoQuartileP50 (viewers who reached the midpoint) from the Google Ads API. Both metrics are weighted by view volume across active video campaigns, so campaigns with more views have more influence on the score. This check only runs when your account has active video campaigns.
AdGradr flags completion rates below 10% as a serious concern and rates between 10% and 20% as a warning. Rates above 20% pass the check. The report also surfaces the midpoint rate (P50) as context. A high midpoint rate with a steep drop to completion signals the video loses people in the second half.
Why this matters
Section titled “Why this matters”View rate tells you whether someone started watching. Completion rate tells you whether they stayed. A viewer who watches your full ad is far more likely to recall your brand, visit your site, or convert later.
Low completion rates also indicate wasted spend. You are paying for views where the audience disengages before seeing your call to action or key message.
What good looks like
Section titled “What good looks like”Completion rates above 20% are solid for in-stream ads. Shorter creatives (15 seconds) naturally achieve higher completion rates than 30- or 60-second spots, so compare within the same duration range.
A healthy account will show a gradual drop from P50 to P100, not a cliff. If 40% reach the midpoint but only 5% finish, the back half of the video needs work.
Common mistakes
Section titled “Common mistakes”- Burying the value proposition. If your core message appears at the 25-second mark of a 30-second ad, most viewers will never see it.
- Overly long creatives. A 60-second ad needs to justify every second. If the story can be told in 15, trim it.
- No pacing variation. A monotone delivery with no visual changes causes drop-off. Vary the pace, introduce new visuals, and use text overlays to re-engage.
How to fix it
Section titled “How to fix it”- Map the drop-off curve by comparing P25, P50, P75, and P100 quartiles for each campaign. Identify exactly where viewers leave.
- Front-load your key message. The call to action or core benefit should appear before the midpoint.
- Test shorter versions of the same creative. Often a 15-second cut of a 30-second ad will outperform on completion while delivering the same message.
- Use end screens and companion banners to capture intent even from viewers who do not finish.
When to ignore this check
Section titled “When to ignore this check”Non-skippable ads (bumper and 15-second non-skip) will mechanically show high completion rates. If your account runs mostly non-skippable formats, completion rate is less diagnostic and the view rate check is more relevant.
