Video Completion Rate: What Good Looks Like

The benchmarks, by environment and length

Industry-reported data puts premium streaming and CTV completion at 90%+ generally, with some ad-supported CTV platforms reported as high as 97.2% and non-skippable CTV pre-roll specifically at 98.6%. Length matters too: 30-second CTV ads reportedly complete at around 95.9%, 15-second ads at 93.9%, and ads of 10 seconds or under at 90.4% — the counterintuitive detail here is that on non-skippable CTV, longer creative can complete about as well as shorter creative, because the viewer was never going to have the option to skip either way. That's a real departure from the "shorter always completes better" assumption that holds on skippable formats.

Why CTV and mobile aren't comparable numbers

Combined PC and mobile video completion averages around 62% — a very different number from CTV's 90%+, and not because CTV creative is inherently more compelling. The mechanism is structural: CTV is overwhelmingly non-skippable, watched in a lean-back living-room context; mobile and PC video is frequently skippable, watched during active browsing with constant competing demands on attention. Comparing a 62% mobile VCR against a 95% CTV VCR as if one campaign is simply outperforming the other misreads what's actually being measured.

A worked example

A Prime Video campaign running 30-second creative at a 92% completion rate is performing in line with, or slightly below, the reported benchmark — a reasonable result, not a standout one. If the same brand's mobile OLV creative completes at 58%, that's close to the reported 62% average for that format, not evidence the OLV creative is failing relative to the CTV one. Reading both against their own format's benchmark, rather than against each other, is the only way to tell whether either is actually underperforming.

Completion rate is also the fastest available signal on a brand-new streaming line item — it's readable within days, well before enough time has passed for branded search or sales data to be trustworthy. reMKTR runs 109 live Amazon DSP advertiser seats, and checking completion rate in week one, against the specific format's benchmark, is the standard first checkpoint before anything else on a new streaming flight, because it's the earliest point at which a genuine creative problem becomes visible.

When a low completion rate is a real signal

If CTV completion sits meaningfully below 85%, that's worth investigating — check length against the platform's accepted durations first, since a length outside what the placement is optimized for can hurt delivery and completion together, then check the opening seconds of the creative itself. If OLV completion sits well below the reported 62% average, check whether the creative front-loads its message assuming a skip option won't be used — OLV viewers who can skip generally do, within the first few seconds, if the hook doesn't hold.

Frequency is worth checking too, before touching the creative. A completion rate that starts strong and declines over the course of a flight, with no creative change, often points to over-frequency rather than a bad asset — the same household seeing the same ad for the fifth time in a week is simply less likely to watch it through, and the fix is a tighter frequency cap, not a new cut of the video.

The common mistake

The mistake is treating one universal VCR target across every format and length in a media plan, then judging every line item against it regardless of context. A 92% CTV completion rate and a 60% OLV completion rate can both be genuinely good results on their own terms — set the benchmark per format and length, not one number for the whole plan. reMKTR reports completion rate against the specific platform and duration benchmark for every line item, rather than a single blended completion target across a mixed-format campaign.

A second version of the mistake is chasing completion rate as the only metric that matters. A creative that completes at 96% but produces no branded search lift and no sales movement has held attention without doing anything with it — completion rate proves the ad was watched, not that it worked. Read it as a necessary early checkpoint, not the final scoreboard.
