Whether the channel suits your product
The honest filter is short. Can somebody understand what the product does in three seconds of video, would they buy it without researching, and is it cheap enough to be an impulse? Three yeses and TikTok is worth testing. One or two and the money almost certainly does better elsewhere.
It is worth saying plainly because the pressure to be on the platform is social rather than commercial. A kitchen fitter, an accountant or a B2B supplier can spend a great deal there learning something a five-minute conversation would have said for nothing.
Creative is the cost, not the media
On search you buy intent that already exists. Here you have to create it, and the ad does that job — which means the work is producing enough variations to find one that works, then producing more before it wears out. Ads fatigue fast on this platform, so a single winner is a few weeks of relief rather than a solution.
That is what makes the growth block a sensible shape for it: the hours go into making things, and when the channel stops earning they go somewhere else without a contract renegotiation.
