What Is Attribution Modeling?

Attribution modeling is the method used to assign credit for a conversion across the different marketing touchpoints, such as ads, emails, and organic search, a customer interacted with before converting. The model chosen (last-click, first-click, data-driven) directly affects which channels appear to be performing well in reporting.

Attribution only works as well as the data feeding it: if a tag misses an event, fires late, or is blocked by something like Intelligent Tracking Prevention (ITP), the resulting model doesn’t just have a gap, it actively misattributes credit to the wrong channel. A marketing team can debate attribution models endlessly, but underlying tracking accuracy determines whether any of those models produce a trustworthy answer.
