# What is a Tested User A Tested User is someone who visits your website and is included in at least one Optibase test. Once a user is part of a test, Optibase tracks their behavior and attributes any relevant conversion events to the variant(s) they were shown. This helps you understand how different variants influence user actions — reliably and accurately. *** ### How Tested Users Work When a user visits your site, Optibase randomly assigns them to a variant in an active test. To ensure consistency, the same user will continue to see the same variant on future visits. > *Example: If a user is assigned Variant B of your homepage headline test, they’ll always see Variant B until the test ends.* *** #### Keeping Variants Consistent Tested Users always see the same variant version of any test they’ve previously been assigned to — even if they: * Leave the site and return later * Visit from a different page * Reload or navigate away This ensures the testing experience is consistent and that the data collected remains valid. *** #### Tracking Across Subpages When a user completes a Conversion Event (e.g. clicking a button, submitting a form, completing a purchase), Optibase attributes that conversion to all variants the user was exposed to, even if the conversion occurred on a different page. > *Example: A user sees Variant A on the homepage, then later signs up on the pricing page. That conversion is credited to Variant A.* *** #### Cross-Domain Tracking #### (Business & Professional Plans Only) If your project spans multiple domains, Optibase can continue tracking the same user across those domains — as long as the same Optibase custom script is installed on each site. > *Example: A user lands on your blog at blog.yoursite.com, then visits app.yoursite.io to sign up. Optibase connects the journey as one tested user.* *** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
