I have a query relating to last-touch attribution (somewhat more general than SQL) but it is in relation to task 6 of the Cool TShirts project- https://www.codecademy.com/paths/analyze-data-with-sql/tracks/analyze-data-sql-analyze-real-data/modules/analyze-data-sql-marketing-attribution/projects/analyze-data-sql-attribution-queries
Task 6: How many last touches on the purchase page is each campaign responsible for?
Am I correct in thinking that it’s typical to define last touch as the most recent interaction which led to the end of the attribution spectrum; in this particular case, the purchase page. This would be different to literally the most recent user interaction (e.g. by timestamp) of users who have ever reached the last step of attribution (since it ignores additional visits that didn’t result in the final step-purchase).
If anyone can confirm the standard it would be appreciated, I’ve been struggling to find a proper definition (assuming there is one).
