Attribution Desk - which channel really drove the conversions, and the test that settles it

Paste what each source claims per channel - Google Ads, Meta, LinkedIn, GA4, your CRM or store, a how-did-you-hear survey, spend - and optionally your converting touch paths. Free in your browser: one source of truth for the count, how far the platforms over-claim against it, each channel's cost per real conversion, six attribution models side by side (first, last, last non-direct, linear, time-decay, position-based) and where direct, branded search and dark social hide the real driver. Paid: an attribution readout with the allocation call, and the incrementality test that settles the channel two sources fight over. Derived from the agent skill @coreyhaines31/attribution by Corey Haines (coreyhaines31/marketingskills, MIT).
