To set up client-side a/b testing, integrate the Optimizely Web snippet by adding the script tag with your PROJECT_ID to the page head, enabling snippet-based experiment activation and event tracking across web routes.

Snippet-based activation is a client-side experimentation method that uses the Optimizely Web script tag to load experiments and apply variation data, allowing targeted testing without modifying backend code.

Prevent page flicker during Optimizely experiment loading by applying the snippet's built-in anti-flicker handling, which hides page content until variation data is fully applied.

Yes, you can include optional custom JavaScript hooks alongside the Optimizely script tag to manually activate experiments, apply targeting rules, and read variation data across pages.

No, Optimizely Web snippet integration requires no external dependencies, needing only the inclusion of the Optimizely script tag with your PROJECT_ID to enable client-side experimentation.

The best way to track event outcomes is using the Optimizely Web snippet's built-in event tracking capabilities, which measure experiment results directly through the client-side script.
