Definition
Multi-touch attribution is a method of crediting multiple marketing touchpoints, not just the first or last one, for driving a conversion or customer action.
Instead of giving 100% of the credit to a single channel, multi-touch models distribute credit across every interaction a prospect had before converting. That includes paid search clicks, organic visits, email opens, and phone calls.
For call tracking, this matters because phone calls rarely happen in isolation. A prospect might click a paid ad, visit the site twice, then call three days later. Without multi-touch attribution, that call looks like a direct conversion. The paid ad gets no credit. Budget decisions get made on incomplete data.
Across 72,000+ locations, Convirza sees this pattern consistently: phone calls are often the final step in a multi-session journey, which means the channels that warmed the lead go unmeasured unless attribution spans the full path.
