PPC report. 7 Day Total Sales £ . Confused

Hi there, On campaign reports, I’m confused on how to work out the column headed ‘7 Day Total Sales £’ as the numbers stated don’t add up to my 7day sales or anything else related to my sales. Can someone please explain to me how this works? Thank you.

According to the Amazon help page on Campaign Metrics, when a shopper clicks on one of your ads, they track their activity after the click is registered in case the shopper comes back to purchase a product they clicked on previously.

The time period for measuring purchases after a click is called an attribution window. The standard attribution window for Sponsored Products is 7 days.

If a shopper returns to your product and purchases it within the attribution window, that sale will be included in your sales data.

”For example, if a shopper clicks your Sponsored Products ad on January 29 and purchases the product on February 3, this order occurred 5 days after the click on your ad and would be counted in your sales total.

If the current date is February 5, a month-to-date time range would not include the sales data for clicks generated in January, but a last-month time range would include this sales data.”
