Each tool is a text box. Write or paste your draft, and it is reviewed automatically against named checks. Every run is saved with its date, so you can see what changed between versions.
The offer sentence
This tests the one sentence that says what you sell, before money is spent marketing it. Write the sentence and the five answers people outside your organisation gave, word for word, when you asked them who it is not for.
Not openedEarly accessWhat a customer has to be worth
This works out the most a click can cost you before it stops paying. Write your price, your margin, how often customers buy again and the conversion rate at each step from click to sale, and say which rates you counted rather than estimated.
Not openedEarly accessHow long a test would take
This works out how many visitors a test needs before its result means anything, on your own traffic. Write your current conversion rate, the smallest improvement you want to detect and your weekly traffic, before you design the test.
Not openedEarly accessAttributed against incremental
This sets what an advertising platform says it delivered against what your holdout or pause test shows actually happened. Write the platform's reported figures and your test's figures for the same period; without a holdout there is nothing to compare.
Not openedEarly accessWhere the people actually go
This ranks where people leave your path to a sale by how many people go, not by percentage. Write each step with the number of people at it, the date range, and the system the number came from.
Not openedLevel 0, freeThe ten statement check
Ten statements rated one to five, before Level 0 and again after Level 5. Write your rating for each with the date, and compare the lines that moved with the lines that did not.
