쿠키 없는 A/B 테스트 (동의 배너 불필요)

You changed your headline last month. Did it sell more, or did it just feel better? If you don't know, every change you make to your site is a gamble.

I'm James, founder of Privatus Analytics. Let me show you how to stop gambling.

Here's how it usually goes. You rewrite the page. You watch the chart for a week. It looks a bit better. Someone on the team says it worked. Then next month it's back where it was, and nobody knows if the headline did anything at all. So you change something else. And something else. Every one of them a guess. You tried a testing tool once. It needed a cookie to remember who saw what. That meant a consent banner, and everyone who clicked no was left out of the test. The test only counted the people who said yes. It was another subscription too, on top of your analytics, for a question you ask a few times a year. And the time it did show a winner, you called it after three days, on a lucky streak that never held up. So you went back to guessing. And every guess costs you a month of sales you can't get back.

With Privatus Analytics, the test runs on the script that's already on your site. Nothing to install, nothing extra to pay for. Pick the page, add your new version, and say what counts as a win, like a sale. Press Start. No cookies, so no banner, and every visitor is in the test, not just the ones who clicked accept. Then you wait, and the result is one you can trust. In this example, the new checkout converts at 9.3 percent, against 5.4 for the original. That's 72 percent more sales from the same traffic. A winner is only called when it's real. Never after three days on a lucky streak, and never because of bots, which machine learning filters out of every visit. When it wins, every visitor goes to the winning version straight away, before you've touched your site.

That headline you changed last month? Now you'd know, in one number, whether it sold more. Every change becomes a test instead of a gamble. And every visitor counts, with no banner in sight.
