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.
That one change costs more than a year of Starter.
Your figures stay on this page.
Photos, prices, claims, packaging and offers decide whether a visitor buys. Test them here while your real store stays exactly as it is.
Each simulated shopper starts from your store's own patterns.
Your store sends totals like these, never names. Sample store, Brookside Skin Co.
A live A/B test splits your real visitors and waits. TestFeed is done before your coffee goes cold.
Three ways to find out if a change will sell.

| Cost | From $99 a month | Your traffic, and sales lost to the weaker version | $5,000 to $65,000 a study |

It's not instinct versus shoppers. It's your instinct, tested before you commit, instead of after.
No. It helps you choose which version is stronger. It does not predict sales.
TestFeed works with zero history. The deeper store-shaped value needs some sales data, but you don't need to wait to start.
We never ask for names, emails, phones, or addresses, and the process never contacts your customers directly.
Access locks until you reactivate a plan. Nothing stays behind read-only — pick a plan and you're straight back in.
