Untested changes cost you sales.

Most changes go live untested. When one hurts sales, it usually takes weeks to notice.

This assumes one untested change cuts sales by 5%, and that it takes 6 weeks to notice. Six weeks is about how long a live A/B test takes to call a winner.

One untested change$2,769
Testing it first$99

That one change costs more than a year of Starter.

Your figures stay on this page.

Test the things that matter.

Photos, prices, claims, packaging and offers decide whether a visitor buys. Test them here while your real store stays exactly as it is.

Common questions.

Is this an A/B test?

No. We never split your live traffic.

Why should I trust this over my own instinct?

It's not instinct versus shoppers. It's your instinct, tested before you commit, instead of after.

Will this tell me how much extra money I'll make?

No. It helps you choose which version is stronger. It does not predict sales.

What if I don't have much order history yet?

TestFeed works with zero history. The deeper store-shaped value needs some sales data, but you don't need to wait to start.

Is my customer data safe?

We never ask for names, emails, phones, or addresses, and the process never contacts your customers directly.

What happens if my trial ends or I cancel?

Access locks until you reactivate a plan. Nothing stays behind read-only — pick a plan and you're straight back in.
