In most A/B testing platforms, including Mida, the conversion will be attributed to the first variant the visitor was exposed to.
Here's a breakdown:
Initial Assignment: When a visitor first encounters your test, they are assigned to either the Control or a Variant group. This assignment typically happens on the first page where the test is implemented (e.g., the homepage).
Persistent Assignment: Once assigned, the visitor remains in that group for the duration of the test, regardless of which pages they visit afterwards.
Conversion Attribution: If a visitor initially assigned to the Control group later converts on a page showing a Variant, the conversion will still be attributed to the Control group.
Cross-Page Tracking: This principle applies even if the conversion happens on a different page from where the test was initially encountered.
It's strongly recommended to prevent users from accessing both Control and Variant versions of your pages.
Here's why:
Data Integrity: Allowing users to see multiple variants can skew your results and compromise the validity of your test.
Consistent User Experience: Users should have a consistent experience throughout their journey on your site.
Accurate Attribution: Keeping variants separate ensures that conversions are correctly attributed to the intended test group.
