Copy-paste your website or landing page copy into Copytesting.
Specify which people you want feedback from. There are 14 targeting criteria to choose from (or go for “general audience”).
The minimum number of people to recruit is 20 - so we’d have meaningful sample size for significance calculations.
People from the selected audience will mark parts of your copy as good (interesting, emotional, compelling, etc) or bad (boring, bland, unclear, etc).
Copytesting will highlight parts that are statistically significantly good or bad, or mediocre. This tells you which parts of the copy to focus on.
For every rating copy testers will add comments for what exactly is unclear about something, or what makes itboring, or what's the problem with a particular sentence.
