TikTok cold hooks: open on the product or on the problem?

Picture a home fitness brand running cold prospecting on TikTok where the top performer opens on the product in the first frame. The team wants to keep that style because it converts well on retargeting, and that's where I'd push back. A cold audience isn't looking for the product yet, so the opening has to stop the scroll on something they already feel, like a sore lower back after a day at a desk. The product can show up around second 3 or 4.

My view is that problem-first hooks should be tested on cold traffic and judged on 2-second and 6-second view rates before anyone looks at cost per purchase. Cold audiences convert slowly and the purchase data is thin early on, so view rates tell you whether the hook is doing its job well before cost per purchase has anything useful to say.

I'd side with the product-first camp on warm audiences who already know the brand. Leading with the product is fine there. Do you judge cold hooks on view rates, or do you wait for conversions?

I mostly agree, but I'd lean on the 6-second view rate over the 2-second one on TikTok. The 2-second number gets inflated by people who scroll past without really stopping, so it says less about the hook. I'd still hold off reading either until there's enough spend behind it, since a small test can swing hard on a handful of impressions.

Agreed on the 6-second number. A rule of thumb for trusting it: wait until each creative has roughly 1,000 impressions, and only call a winner if its 6-second view rate beats the others by about 20 percent relative, in the same ad group and audience. Smaller gaps are usually just the delivery system giving one creative a better slice of traffic early on, which is why two hooks can swap places from one day to the next.

It's worth keeping that strict because cold hooks are the noisiest part of the test. A problem-first and a product-first opener can look almost identical for the first few hundred impressions and then pull apart. Kill the slower one too early and you never find out whether it would have kept people through to the offer.

1,000 impressions and the 20 percent bar both make sense to me. What I'd watch is whether the two hooks are getting comparable traffic. On TikTok, a creative that lands a better early slice can look like a winner purely because of how it was delivered. If the spend split is lopsided after the first day, the 6-second number isn't comparing the same thing yet.

Agreed, and the fix is simple: look at the impression split before you read the 6-second rate. If one hook has already taken 70 percent of impressions in the first day, the comparison is lopsided from the start, so hold off until both have roughly similar delivery.
