Copywriter Testing Tool FAQ
How does this help my copywriting workflow?
Instead of guessing which headline or CTA will perform best, you can test 2-3 options with 500 simulated Americans before presenting to your client. This gives you data to back up your recommendations and helps you deliver stronger work.
Can I test full ad copy or just headlines?
You can test anything—headlines, full body copy, email drafts, ad copy, landing page text, or CTAs. Each variant can be up to 10,000 characters on the email platform setting.
Can I share the results with my client?
Absolutely. Results include clear demographic breakdowns and sentiment analysis that make excellent additions to client presentations. You can share the results link directly or export data as CSV.
What demographics do the simulated audience represent?
Each AI persona includes age (18-29, 30-44, 45-59, 60+), education level, political leaning, US region, and urban/rural classification. This helps you see how different audience segments react to your message.
Is my copy kept confidential?
Yes. Your content is only used for testing and is deleted after 30 days. We never share, publish, or use your message for any other purpose. Client confidentiality is maintained.
How accurate are AI persona reactions compared to real audiences?
SimAudience is a synthetic simulation, not a survey of real people. Results provide directional guidance—think of it as a structured second opinion from diverse perspectives. It works best as a pre-launch filter before investing in real-world testing.
Important: SimAudience uses simulated audience modeled on demographic data. This is a synthetic simulation, not a survey of real people. Results should be used for directional guidance only and are not a substitute for real-world audience testing.
