What attribution model gives credit to only one touchpoint, it being the first?
Single-touch attribution model (first click or visit)
What attribution model should be used to better understand how to value the first click or visit in a conversion path, especially when success is defined within a longer attribution window or a longer consideration period?
Single-touch attribution model (first click or visit)
What attribution model gives no credit to impressions or later touchpoints that could have incremental effects on your conversion rate, and may oversimplify conversion paths that rely on middle- and lower-funnel activity?
Single-touch attribution model (first click or visit)
Scenario:
A conversion path contained ONLY an impression, then a click, and then a visit 30 seconds later. If the click and visit happened more than 30 seconds apart, the click would get 100% of the attribution. But because the click and the visit happened less than 30 seconds apart, they count as the same touchpoint and get 100% of the credit for the conversion. What attribution model is being used?
Single-touch attribution model (first click or visit)
