What is hook rate?

A number built from two columns

No ad platform ships a column called hook rate. Advertisers named it, and they build it by dividing two figures the platforms already report. In Meta Ads Manager those figures are 3-second video plays and impressions. An ad served 40,000 times that played for three seconds on 12,000 of those impressions has a hook rate of 30 percent. Because it is a derived number, it only means something when both inputs come from the same ad, the same date range and the same placement. Pull impressions from an ad set and plays from a single ad, or combine two weeks of plays with one week of impressions, and the result looks precise while describing nothing real.

How each platform counts the early view

Meta counts a 3-second video play when the video plays for three seconds, or for 97 percent of its length if it is shorter than three seconds, and each impression is counted separately with replays excluded. TikTok Ads Manager has no three second count. Its nearest figures are 2-second video views, which need at least two seconds within one impression session, and 6-second video views, which count six seconds, a complete play of a shorter video, or at least one engagement within the first six seconds. YouTube's analytics describe viewing through average view duration and average percentage viewed rather than a fixed early threshold. A hook rate from Meta and one from TikTok are therefore two different measurements that happen to share a name.

Reading a high or low number

A low hook rate points at the opening: the first image, the first words on screen, the first movement, or a mismatch between the opening and the audience being targeted. A high hook rate with poor results further down the funnel points somewhere else, usually at a promise the rest of the video does not keep. There is no universal good figure, because placement, audience, format and offer all move the number, and published benchmarks rarely say how they were measured. The comparison that holds up is against your own ads: the same placement, similar audiences, similar spend, several versions of the opening tested at the same time. Small differences between two versions with only a few thousand impressions each are usually noise.

When it matters most

Hook rate earns its place in feed placements, where a video starts playing without anyone choosing it and the viewer's thumb is already moving. It matters less where somebody has deliberately pressed play, such as a video on a product page or a tutorial opened from search, because the decision to watch was made before the first frame. It is most useful while testing creative: several openings for the same body and offer, run side by side, where hook rate is the fastest signal to arrive and the cheapest to act on.

Common mistakes

Comparing a Meta hook rate against a TikTok one built on 2-second views is the most frequent error. Dividing by reach instead of impressions inflates the figure whenever people saw the ad more than once, because plays are counted per impression. Judging an ad after a few hundred impressions treats chance as a result. Chasing the number for its own sake produces openings that grab attention with something the product cannot deliver, which lifts hook rate and sinks everything after it. And mixing organic and paid views in one calculation blends audiences that behave very differently. Keep the calculation boring and consistent, and let the creative be the variable.

Where the opening is made, and where it is measured

The video builder does not report views, impressions or retention, so hook rate is measured in Meta Ads Manager or TikTok Ads Manager after the exported MP4 is uploaded as an ad. What the builder shapes is the opening itself. Videos export in landscape at 1920 by 1080 or vertical at 1080 by 1920, at 30 frames a second. A promotional scene runs 2.5 to 4 seconds with 5 to 8 words of narration, so the first scene alone covers most or all of the three second window. Captions are on by default for every scene, which keeps the opening line readable for anyone watching without sound. A share link plays in a browser player rather than delivering a file, so upload the MP4 itself to the ad platform. For writing the opening line, the UGC ad script guide covers the patterns in detail.
