Our attribution model is the industry standard. If a user visits your site and clicks on a Perform recommendation, and returns to the site within 30 days and buys the product they clicked on/converts, then full attribution for the conversion will be given to Perform.
A question that gets asked a lot is, "what if a user engages with a recommendation, returns to the site and purchases the item, plus other items they weren't recommended?"
Episerver Perform will only be attributed the revenue generated solely from the item recommended to the user and engaged with (i.e. clicked on) and not the entire basket value.
Example: A user is recommended a T-shirt for £15 while browsing the site. They click on the recommended T-shirt, however they leave the site without purchasing. The user returns later that day and purchases 2 of the T-shirts they were recommended and engaged with. They also purchase a Jumper for £30 that they were not recommended. The order total is £60 and the total revenue attributed to Perform would be £30 (2x £15 T-shirts).
If the user buys multiple units of the same item that was recommended to them and clicked on, this collective sum will be attributed to Perform. Equally, if it was just one item, solely the value of that one item will be attributed to recommendations.
We can produce a graph that plots attribution against time. This will show you when most people convert having been shown a recommendation. The metrics used are CPC (Click to purchase conversion) against time.
Our experience shows that on average 85% of conversions occur within 24 hours.
So the graph will look somewhat like the below:
