SplitStat

SplitStat is an A/B testing tool for websites. Marketers and product teams use it to test changes to their pages, from a new headline to a whole new landing page, and see which version brings more conversions. Build tests without a developer Paste one tag into the head of your site once. After that, most tests are built in the browser.

Preview each variation on your own page before it starts, and save a change for desktop, mobile or both. Developers can use the HTML, CSS and JavaScript code editor. Single-page apps are supported. Every test type in one place - A/B tests on the same URL - Split URL tests that send visitors to a second address - Multipage, A/A and cross-domain tests - Rollouts that serve a change to any share of visitors, on Growth and Enterprise - Mutual exclusion groups, so a visitor sees at most one test from a group, on Growth 250K and above and on Enterprise Show each test to the right people Target by URL, device, browser, operating system, country, language, traffic source, UTM, referrer, returning visitors and day of the week. Save an audience once and reuse it. Measure what matters to you Track events with no code, or send your own with event parameters. Judge a test on unique conversions, total conversions or value per visitor, and add guardrail metrics for the numbers a winner must not hurt. Each result shows the lift, a likely range and a clear verdict. Connect Google Analytics 4 and Microsoft Clarity.
