What Are Multi-Touch Attribution Models, Really?
Single-touch? Laughable. Last-click says the final ad closed the deal. Wrong.
Multi-touch spreads the love. Customer sees Instagram story. Clicks email. Browses site. Buys. Each gets partial credit.
Analogy time: Like a relay race. No one runner wins alone. Models quantify each leg.
For beginners: Attribution = “who gets the gold?” Multi-touch = fair shares.
