Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Incrementality Estimator, so you can see the experience inside your AI.

It does not authenticate your account with Incrementality Estimator. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions Incrementality Estimator owners ask.

  • 01

    What is the difference between reported ROAS and true incremental ROAS?

    Reported ROAS treats all conversions as campaign-attributable, which usually overestimates value. True Incremental ROAS uses the calculate_roas_comparison capability to factor in the baseline conversion rate derived from the control group, providing a much more accurate measure of marginal return.

  • 02

    I only have raw cohort sizes and conversions. What should I run first?

    You must start by using the calculate_baseline_metrics capability. This establishes the fundamental conversion rates (Control CR and Exposed CR) needed for all subsequent lift calculations.

  • 03

    How do I find the absolute number of extra conversions? Which capability handles this?

    The calculate_incrementality_metrics capability is designed for this. It takes your baseline CR and exposed performance data to calculate the absolute incremental conversions, telling you exactly how many extra sales were achieved.
