Cook Candle: which opening line sells a kitchen candle

Too early to callAd copy · writing structureStarted 12 Oct
£589 spent across 5 versions in 7 days. Too early to call; verdict due around 9 Nov.
What we think

Same message (the Cook Candle clears cooking smells) written five ways. We think a scene or a question lands better than a product description, because the reader has to recognise the problem before the solution means anything.

What is different between the versions

The opening structure of the primary text only. Same three videos, same link, same audience.

When we call it

£150 spent on each version, or 28 days, whichever comes first. Not before.

What this will tell us

Which structure to lead with across Pott product copy. The Tomato round uses the same structures, so the two reads stack.

How this is read

The 5 texts run as options inside 3 ads. Meta chooses which text each person sees, so the texts never get equal spend, and Reels and Stories show no primary text at all, so text spend adds up to less than the ads' total. Per-text results are a steer, not a verdict: a colder text can look weaker while still doing its job for people who are not ready yet.

Spend, clicks and purchases are as reported by Meta for the ads in each test, from the test's start date to today, which is partial. Where versions share an ad set, Meta decides how much each one spends, so compare cost per purchase and purchases per click rather than totals. A test is only called once its rule is met; stopping early on a good week is how false winners get made.
