Hook × variant matrix — 4 hooks × 3 variants = 12 cells
Powered — each variant can earn a reliable read
Choose your platform and lay out the test: how many hooks, how many variants per hook, and the spend behind each. Set your CTR benchmark and the downstream conversion goal that defines a winner. The calculator builds the hook × variant matrix, sizes the recommended budget and per-hook split, estimates clicks per variant, and tells you whether the test is powered enough to trust.
A hook test compares different opening ideas to understand which message earns attention fastest. For short-form video ads, the first few seconds often determine whether users watch, click or ignore the creative. Because the hook gates everything downstream, improving it lifts the whole funnel — which is why hook rate and thumb-stop rate are the first metrics serious short-form teams optimise.
Recommended budget is the number of cells in your matrix multiplied by the spend per variant. From spend and a typical platform CPM, the calculator estimates impressions and then clicks per variant using your CTR benchmark. If clicks per variant fall below the reliable-read floor, the test is underpowered — the apparent winner may just be variance. The fix is more spend per variant or fewer hooks.
If the test is powered, run it and judge hooks against your benchmark and conversion goal — not on gut feel. Iterate the winners into fresh variants rather than starting over each time. To plan the broader creative test this sits inside, use the creative testing budget calculator, and to make sure you have enough raw material, the creative volume calculator.
This calculator plans a hook test. ElenIQ’s Loki measures one in flight — tracking hook rate, thumb-stop rate and downstream performance across your short-form creative, so winning openings surface quickly and feed straight into the next round of creative testing.
A hook test compares different opening ideas to understand which message earns attention fastest. For short-form video ads, the first few seconds often determine whether users watch, click or ignore the creative, so testing hooks is one of the highest-leverage forms of creative testing.
Hold the body of the ad roughly constant and vary the opening. A clean matrix is several distinct hooks, each with a few variants, so one weak execution does not bury a strong idea. The total cells — hooks × variants — drive the budget and data you need.
Each variant needs enough impressions to read its hook rate and CTR reliably — a common floor is around 100 clicks per variant. Below that, normal variance can crown the wrong hook. The calculator estimates whether your spend per variant clears that floor.
A hook wins when its hook rate (the share of viewers who watch past the first few seconds) and its click-through rate beat your benchmark, backed by enough downstream actions to trust the result. Set the benchmark and conversion goal before the test so the decision is objective.
ElenIQ’s Loki tracks hook rate, thumb-stop rate and downstream performance across your short-form creative, so winning openings surface quickly and can be iterated — turning hook testing into a repeatable engine rather than a one-off.
Use Loki to track hook rate and thumb-stop rate across your short-form creative, so the best openings surface fast and feed the next test.
