Tools
Each tool takes a draft and returns a review against named tests. Every run is kept and dated, so you can see what changed between versions.
The offer sentence
Scores your one-sentence offer on what it fails to name, and reads the five verbatim answers you collected to the exclusion question. It rejects nine specific words on sight and it will not run on fewer than five answers.
Not openedWhat a customer has to be worth
Computes gross profit per customer, value per click and the maximum a click may cost you, on your numbers. It will not give you a maximum cost per click if your conversion rates were estimated rather than counted.
Not openedHow long a test would take
Computes the sample each variant needs and the weeks that takes at your traffic, then tells you what a declared winner would be worth if you stopped early. It refuses any minimum detectable effect above 25 per cent relative.
Not openedAttributed against incremental
Reads your holdout or pause test against what the platform reported. Without holdout figures it computes nothing at all, and says why in the terms of the counterfactual.
Not openedWhere the people actually go
Takes your own funnel steps with the count at each and ranks the losses by people rather than by percentage. It refuses counts that rise, and refuses any step without a date range and a named system.
Not openedThe ten statement check
Ten statements rated one to five, taken before Level 0 and again after Level 5. It reports the lines that moved and the lines that did not, and says plainly that the total is the least informative thing on the page.
